Provides three types of adjustment: electronic exposure control, gain control, and autoiris lens control.
AutoExposure and AutoGain are normally enabled to maintain consistent image brightness in video surveillance applications with varying indoor/outdoor lighting conditions. In darkening conditions, the exposure will increase up to the auto exposure knee point (default: 25 ms). Next, gain will increase up to the auto gain knee point. In still darker conditions, the exposure time may increase up to the maximum possible value (this may produce blurry images). In the very darkest conditions, additional digital gain may be applied. Very high gain may result in noisy (snowy) images that compress poorly and consume more network and storage capacity. If the gain is very high, it is best to open the lens aperture or otherwise provide more light to the camera.
The AutoIris extends the ABC capability by opening the lens aperture to admit more light in low light conditions. In bright sunlight, the iris closes to increase the image clarity and depth of field. Most camera models use 4-wire DC AutoIris lenses (also called DC AI, direct drive, or galvanometric lenses). Large-format cameras with motorized 35-mm lenses do not normally use AutoIris. Instead 35-mm lenses typically use one aperture in the day (e.g. aperture=2.8) and another at night (e.g. aperture=16).
Specifies the ABC mode used to calculate luminance. The calculation is performed in the region of interest defined by the Auto Window.
Peak Detect: Used to regulate only the brightest pixels. Use with a high Target Brightness (90) for outdoor use (sun, snow) or where bright lights are present.
Median: Ignores extreme bright and dark. Use with a Target Brightness of 30 to 50 for general purpose or indoor conditions.
Average: Similar to Median, but includes all pixels.
Dark Detect: Provides consistent appearance of the darkest pixels (areas of shadow). Use with a low Target Brightness value (10 to 20).
The luminance (image brightness) target. The value is expressed as a number between 0 (darkest) and 100 (brightest). If the Auto Window is enabled, the average luminance evaluated against the target is computed only in the region of interest defined by the AutoWindow.
Enables or disables the AutoExposure control (default is enabled). If you disable the AutoExposure function, you can specify the precise exposure in units of milliseconds. Part of the Auto Brightness Control (ABC).
Enable this option to permit longer exposures when working in very dark environments. You may also use this option to specify a short maximum exposure to capture images of moving objects such as vehicles. Otherwise the exposure will be automatically limited to values that do not reduce the frame rate.
The longest exposure time in AutoExposure mode, measured in units of milliseconds. If the target is moving, long exposures may cause the image to blur. Set the maximum exposure to 1 to 3 ms to capture blur-free images of moving vehicles. Extremely long exposures will reduce the frame rate for image capture.
Enables or disables the AutoGain control (default is enabled). If you disable the AutoGain function, you can specify the precise gain. The minimum gain is 1 (1X). The analog gain in most models ranges up to 16X. Digital gain is used to achieve the highest gain values. Digital gain shifts lower bits (gray levels) in the digital image data to higher bits. Part of the Auto Brightness Control (ABC).
The highest gain factor in AutoGain mode.
Enables or disables the AutoIris control (default is disabled). Recommended for DC Iris cameras only. Part of the Auto Brightness Control (ABC).
Note - The Aperture control feature is not supported by most camera models. The Aperture setting is available only on cameras that use 35-mm motorized lenses, such as the Le259 and Le11059.
The Aperture control allows the user to remotely adjust the lens aperture (iris diaphragm). The numerical value is expressed as the relative aperture or f-number of the lens. Larger values of the f-number correspond to narrow physical apertures that admit less light but increase the depth of field (ability to focus on both near and far objects).
To change the aperture setting:
Use the "+" button to increase the f-number (reduce the iris opening, admit less light).
Use the "-" button to decrease the f-number (increase the iris opening, admit more light).
You may also enter the f-number in the field provided (e.g. "4" for f/4, where the aperture diameter is 1/4 of the focal length of the lens).
Note that not all values of the f-number are permitted, depending on the features of a particular lens.
Note - The Focus Settings feature is not supported by most camera models. Focus Settings are available only on cameras that use 35-mm motorized lenses, such as the Le259 and Le11059.
The Focus Settings control allows the user to remotely adjust the lens focus through the web page user interface. The numerical focus value is expressed in arbitrary units.
To change the Focus Settings:
To focus at nearer points, use the buttons denoted "<<<" (large/coarse step), "<<" (medium step), or "<" (fine step).
To focus at more distant points, use the buttons denoted ">>>" (large/coarse step), ">>" (medium step), or ">" (fine step).
You may also enter a numerical value in the field provided (e.g. "4" for f/4, where the aperture diameter is 1/4 of the focal length of the lens).
Note that not all values of the f-number are permitted, depending on the features of a particular lens.
White Balance ensures that images have accurate color.
Perform auto white balance (AWB) on an ongoing basis when enabled (default is enabled). The calculation is performed in the region of interest defined by the Auto Window.
If you disable the Continuous White Balance option, a Single Calculation button will be displayed to allow you to perform a one-time white balance. When performing the white balance, it is best to (1) place a white to gray card in front of the camera, or (2) set the AutoWindow to include a white to gray area. Users can also manually enter color gain values to allow for custom artificial lighting.
Preset: The white balance preset is used to constrain the gain in each color channel based on the light source, such as a warm incandescent or a cool fluorescent. The preset can be set to default, wide, fluorescent, and daylight. There is also a user option to allow for specialty artificial lighting.See also the description of the Lighting Source option in the Image Settings menu.
Defines a smaller region of interest within the overall field of view that is used by Auto Brightness Control (ABC) and auto White Balance (AWB) functions (default is disabled).
If disabled, the entire image is used for AutoExposure, AutoGain, AutoIris, and White Balance calculations.
The Auto Window is defined relative to the current image/region of interest, which is set using the Geometry options. It is possible for the Geometry and Auto Window settings to conflict and produce warning messages.
AutoWindow horizontal offset in pixels, measured from the left edge.
AutoWindow vertical offset in pixels, measured from the top edge.
AutoWindow width in pixels.
AutoWindow height in pixels.
These are settings that adjust and fine tune the image quality.
Increases or decreases the mid-tone brightness. A typical gamma value is 1.4 (default). The useful range of values lies between 1 (darker) and 2 (brighter).
The contrast of the image, with a value between -100 and +100, for example:
0 (default) no change from the input; 50 increased contrast; 100 maximum contrast; -50 reduced contrast, and -100 no contrast.
The brightness of the image, with a value between -256 (black) and +256 (white). In technical terms, the brightness is the offset of the transform applied to the image's Y component or luminance.
The edge enhancement (image sharpening) level: high (sharpest, factory setting), alternate, default, or off (no enhancement).
Enable automatic adjustment of the JPEG compression level (default is enabled). Auto JPEG Quality helps to maintain consistent bandwidth and storage utilization even for very complex/busy images of snow, rain, leaves, sun/shadow, etc.
The JPEG quality level. A JPEG quality value of 90 provides large, minimally compressed image files. Smaller values produce smaller images with higher levels of compression.
The maximum JPEG image size in bytes.
If set to the special value of 0, each JPEG image may occupy the entire size of each buffer segment in circular image buffer allocated in the on-camera RAM.
Allows you to skip (subsample, decimate) or combine (bin) pixels in the image.
On cameras with CMOS image sensors 1X, 2X, 4X or 8X subsampling is provided.
On cameras with CCD image sensors binning from 2X2, 4x4, or 8x8 binning may be provided. Adjacent pixels are summed, resulting in increased sensitivity. Since binning on color cameras combines signal from pixels representing different colors, the camera will set saturation=-100 to generate black and white images when binned.
Width of the image in pixels. Automatically rounded down to the next lowest multiple of 32.
Height of the image in pixels. Automatically rounded down to the next lowest multiple of 8, with a minimum value of 16.
Image horizontal offset, measured in pixels from the left edge. Automatically rounded down to the next lowest even integer.
Image vertical offset, measured in pixels from the top of the image. Automatically rounded down to the next lowest multiple of 8.
If enabled, the image is mirrored from left to right.
If enabled, the image is mirrored from top to bottom.
When the camera is mounted upside down, enable both the X and Y Mirror functions.
Used to obscure parts of the image in order to comply with privacy regulations. Privacy zones can be defined in a grid/checkerboard pattern. Use the Set All and Clear All buttons for quick edits.
Enable/disable and alignment crosshair in the center of the field of view. Not intended for use with privacy maps.
Enable this option to apply the Privacy Map to images from the camera (disabled at the factory).
Set the Privacy Map width (number of columns) and height (number of rows) in the user interface. The default grid dimensions are 4x4. The largest dimensions that can be set in the web page are 16x16. Note that the Grid Width and Height define the number of rectangles in the grid and NOT the size of the rectangles in pixels.
Day-Night camera models come with an automatic moving filter mechanism. In the day mode a glass filter eliminates near-infrared light to provide accurate color. In the night mode, an infrared-transparent glass is used. The night mode will admit near-infrared light from the environment or from active-infrared illuminators. Cameras without the day-night filter mechanism can also use the Day-Night menu to apply automatic changes to color saturation (color or black & white) or the lighting frequency (DC, 60Hz, 50Hz).
Two buttons are provided to assist with configuring the Day/Night settings:
"Indoor" - always sets the lighting frequency to 60 Hz for use with AC-powered artificial lighting.
"Outdoor" - sets the lighting frequency to DC (sunlight, 0 Hz) in Day mode and 60 Hz (artificial light) in night mode.
The time in seconds for which a day/night threshold condition must hold before the day-night filter mechanism switches modes. A short time (10) is best for testing. Long times (60) are recommended in long term outdoor use.
The threshold condition to trigger a change in the day-night mode. For example, gain < 16 for Day Settings, gain > 32 for Night Settings. Trigger criteria based on the gain are preferred. The performance of exposure-based thresholds depends on the lighting frequency setting (DC, 60Hz, or 50Hz).
The color saturation (black & white, normal color, or bold color). A value between -100 (monochrome) and +100 (saturated). Normally between 0 and 30 for color cameras. It is conventional to use -100 for (monochrome) in Night Settings for day-night cameras, since near-infrared light will distort colors.
Modulation frequency of any artificial light source in Hertz (Hz) or cycles per second. If you use AC-powered lighting, set the Lighting Frequency to 50 Hz or 60 Hz in night mode to eliminate lighting flicker and horizontal bands in the image. In such a case, use Trigger Criteria based on the gain, not the exposure.
Use DC (0 Hz) for sunlight or DC-powered lighting.
60 Hz is typical in North America, Brazil, Western Japan (Osaka), South Korea. The exposure will be limited to multiples of a half-cycle time (8.333 ms).
50 Hz is the standard in most of Europe, Eastern Japan (Tokyo), Asia, Africa, the Middle East, Australia, and New Zealand. The exposure will be limited to multiples of a half-cycle time (10 ms).
Enable and disable motion detection alarms (default is disabled).
An alarm occurs when a minimum number of pixels change by a minimum amount in a specified area. The area(s) of interest are selected from a grid/checkerboard pattern called the Motion Map.
The sensitivity of motion detection from 0 to 100, with 100 being the most sensitive. A value of 80 is recommended.
The percentage of pixels in the enabled areas of the Motion Map that must change to trigger an alarm event. A value of 5 to 20 is recommended.
The delay time in milliseconds between motion detection calculations. The time must correspond to a value between 0 and 255 frames. If set too low, objects that are moving slowly may not trigger an alarm. If set too high, fast objects may not trigger a motion alarm. The value entered will alter frame rate calculations.
Show the active regions of the Motion Map as light gray regions within a dark image. This mode is intended to be used only as a setup and calibration tool. Any image sent by the camera will display the motion detection mark-up. You cannot select Show Motion Detected at the same time.
Show the motion detected a bright overlay within a dark image. This mode is intended to be used only as a setup and calibration tool. Any image sent by the camera will display the motion detection mark-up. You cannot select Show Motion Detection Regions at the same time.
Set the Motion Map width (number of columns) and height (number of rows) in the user interface. The default grid dimensions are 4x4. The largest dimensions that can be set in the web page are 16x16. Note that the Grid Width and Height define the number of rectangles in the grid and NOT the size of the rectangles in pixels.
Enable this option to register alarm events due to a signal voltage applied to the general purpose input terminals.
Enable this option to trigger the general purpose input on the edge (transition) of a voltage pulse rather than a voltage level.
Enable this option to have the general purpose input trigger on a negative level or falling edge rather than a positive level or rising edge.
The general purpose input debounce (response) time constant in units of milliseconds.
The minimum delay in seconds between two consecutive alarm notifications. Notifications will be suppressed for alarm events that occur more frequently.
Output Select: The operating mode of the general purpose output terminals.
Valid settings are:
on: The output is active.
off: The output transistor is turned off.
alarm: Pulse once when an alarm occurs. The pulse may be due to a motion detection Motion Alarm event, a pulse on the general purpose input IO IN Alarm, or both, depending on the alarms configured by the user.
start_of_readout: Pulse once per frame. Pulse after line 1 of the image completes its exposure. This is the appropriate setting to use to trigger external strobe lighting with rolling shutter CMOS cameras. Line 1 of the image will not be exposed to the flash. The exposure must be made long enough to expose all remaining lines of the image.
strobe: Pulse once per frame. Pulse duration matches the exposure time. This is the appropriate setting to use to trigger external strobe lighting with global cameras.
Enable this option to send alarm notifications via email in response to alarm events. The email response may be due to a motion detection Motion Alarm event, a pulse on the general purpose input IO IN Alarm, or both, depending on the alarms configured by the user.
The email address (e.g. user@domain.com) that receives emails upon a motion alarm event.
The subject of the email message that is sent upon a motion alarm event.
The IP address or DNS name of the server that is used to send an email message upon a motion alarm event.
Enable this option to provide image uploads to an FTP server in response to an alarm event. The image upload may be due to a motion detection Motion Alarm event, a pulse on the general purpose input IO IN Alarm, or both, depending on the alarms configured by the user.
The IP address or DNS name of the target FTP server.
The file path for JPEG image files uploaded to the FTP server. File names may include date, time, and image sequence information.
Example 1. To include the year, month, day of month, hours, minutes, seconds, and milliseconds in the file name, enter alarm%Y%m%d%H%M%S%%Q.jpg.
Example 2. Use image%%05i.jpg to specify a relative image number to 5 digits (a negative number for pre-alarm images, positive for post-alarm).
The user login on FTP server. (default: ftp)
The password associated with the FTP server login. (default: ftp)
The pre-alarm period in seconds (default is 0). The specified pre-alarm JPEG images in the on-camera circular buffer memory will be uploaded to the FTP server when an alarm event occurs. Since new images are always being added to the rolling image buffer while the oldest images are overwritten, the practical maximum value is related to the API property number_of_buffers and the camera frame rate.
The post-alarm period in seconds (default is 0).
Select the Passive option to enable passive (PASV) mode FTP. The default setting is disabled.
The frame rate in frames per second at which images are to be uploaded to the FTP server. If larger than the current framerate, JPEG images will be transferred as fast as possible given capacity for data transmission. (default: 1000)
Enable to provide alarm notifications via UDP. The response may be due to a motion detection Motion Alarm event, a pulse on the general purpose input IO IN Alarm, or both, depending on the alarms configured by the user.
When an alarm occurs, a UDP packet is sent up to three times to the Client(s) on the specified port. The packet is the following human readable format using CRLF as the separator:
Event number - an incrementing unsigned long integer
IP address - the camera's IP address (xxx.xxx.xxx.xxx)
Hardware address - the camera's hardware (MAC) address (00:0B:E2:xx:xx:xx)
Trigger time - the time the trigger occurred (Tue Jun 10 12:09:46 2006)
Trigger reason - one of:
motion-centroid x:%d y:%d area:%2.4f (specifies the x,y coordinates where the motion was detected).
I/O input triggered.
To acknowledge the alarm packet, send a UDP packet containing the event number in human readable format to the source address and port of the alarm packet. If not acknowledged, the alarm packet will be resent at one second intervals, to a maximum of three packets.
A comma-separated list of the target client addresses that will receive UDP alarm packets. If the broadcast IP address for the subnet is specified, alarms will be broadcast. Each client address can include an optional appended port number, delimited by a colon.
The target client port that will receive UDP packets upon an alarm event. The port can also be specified in alarm_udp_client using a colon (e.g. 123.123.123.123:9999).
The file path for JPEG image files uploaded to the FTP server. File names may include date, time, and image sequence information.
Example 1. To enter include the year, month, day of month, hours, minutes, seconds, and milliseconds in the file name, enter alarm%Y%m%d%H%M%S%%Q.jpg.
Example 2. Use image%%05i.jpg to specify a relative image number to 5 digits (a negative number for pre-alarm images, positive for post-alarm).
The user login on FTP server. (default: ftp)
The password associated with the FTP server login. (default: ftp)
The pre-trigger period in seconds (default is 0). The specified pre-trigger JPEG images in the on-camera circular buffer memory will be uploaded to the FTP server. Since new images are always being added to the rolling image buffer while the oldest images are overwritten, the practical maximum value is related to the API property number_of_buffers and the camera frame rate.
The post-trigger period in seconds (default is 0).
Select the Passive option to enable passive (PASV) mode FTP. The default setting is disabled.
The frame rate in frames per second at which images are to be uploaded to the FTP server. If larger than the current frame rate, JPEG images will be transferred as fast as possible given capacity for data transmission. (default: 1000)
Enable this option to provide RTP/RTSP streaming capability.
To view an RTP/RTSP stream, issue a streaming media player application such as QuickTime from Apple Computer. Under QuickTime's main menu, select File.. Open URL and specify the URL using a camera IP address such as rtsp://123.123.123.123/. You may also specify a DNS name such as rtsp://CameraModel-0d0000.local/. Some web browsers may also allow you to click on the rtsp:// and rtp.dsp links provided in the camera web pages.
The frame rate in frames per second for RTP transfer. The RTP frame rate may be affected by the image width or height (see Geometry) as well as the exposure or Maximum Exposure (see AutoExposure). Network capacity may also affect the perceived frame rate.
The size of RTP packets in bytes. A size of 1450 bytes ensures that Ethernet fragmentation does not occur. A size of 65400 bytes provides much faster transfers. Your RTP client software may assume that the size is 1450 bytes as directed by RFC 2035.
The RTP base port number, which must always be an even number. This is different from the RTSP port number, which is always at the IANA standard location of 554.
Use these options to specify the network configuration of the camera. Click on the Save Settings link to retain any changes you make to Network Settings in the event of a reboot or power loss. After saving settings, you must click on the Reboot Camera link to reboot the camera using a new IP address and network settings.
The factory default setting will normally have the camera seek to automatically acquire an IP address using DHCP (Dynamic Host Configuration Protocol). While this is useful during initial setup, you will normally want to deploy multiple cameras using either a user-defined static IP address or the camera-specific link-local IP address.
The link-local IP address is derived from the MAC address as (169.254.93+MAC5.MAC6). The link local IP address is indicated on the Status page and can also be found on the white label affixed to every camera.
The camera's hostname. For example, if the camera's default hostname is "CameraModel-0c04d1" (camera model with latter portion of the MAC address), and the default DNS domain name is 'local', the camera can be reached using the fully qualified domain name: http://CameraModel-0c04d1.local. Any hostname specified by a DHCP server will override the name set on the camera.
A string describing the camera. In the web page user interface, this string is displayed in the banner at the top of the screen. By default the contents state the camera model and last 3 bytes of the MAC address. Users can edit the description.
Select on (the usual default) to acquire an IP address from a DHCP server at boot time. Select off to set a static IP address on the camera to use at the next boot.
The IP address the camera will use after the next reboot if DHCP is disabled. Use this field to set a static IP address. Remember to click on first on Save Settings and then on Reboot Camera to start the camera using your new Network Settings.
The subnet mask the camera will have after the next reboot if DHCP is disabled. The most typical value of the netmask is 255.255.255.0 for a private IP addresses. Private IP address ranges are: Class A - 10.0.0.0 to 10.255.255.255, Class B - 172.16.0.0 to 172.31.255.255, and Class C - 192.168.0.0 to 192.168.255.255.
You should normally also use a netmask of 255.255.255.0 on any host computer that will communicate with the cameras. The most common exception is in a cases where you specify the link-local IP address (169.254.93+MAC5.MAC6) for the cameras in use. Use a netmask of 255.255.0.0 on your computer if you will be specifying the link-local camera IP address.
The address of the gateway the camera will use after the next reboot if DHCP is disabled.
The nameserver that the camera will use after the next reboot if DHCP is disabled.
To synchronize the time in the camera with the time on your computer, click on the button provided.
Network Time Protocol (NTP) is used synchronize clocks of devices over variable-latency networks. Enter a list of NTP servers separated by spaces. Enter a null string to disable NTP. Use NTP servers to keep the clock in each camera synchronized with other devices on the same network.
The time zone specified in standard Unix (SUSv2) format. Some examples follow.
JST-9 This means that Japanese Standard Time (JST) is 9 hours later than Coordinated Universal Time (UTC) and does not have daylight saving time.
MST7MDT This means that Mountain Standard Time (MST) is 7 hours earlier than Coordinated Universal Time (UTC). Both standard time and daylight saving time apply to this locale. By default Mountain Daylight Time (MDT) is one hour ahead of MST.
NST3:30NDT2:30 This means that Newfoundland Standard Time (NST) is 3.5 hours earlier than Coordinated Universal Time (UTC). Both standard time and daylight saving time apply to this locale. Newfoundland Daylight Time is 2.5 hours earlier than Coordinated Universal Time (UTC).
Enable this option to provide an on-screen timestamp in the image.
Enter text, such as 'CAMERA 123' that will be displayed when the on-screen timestamp is enabled. Text is limited to 15 characters. All text will be displayed using upper case characters. The Western European (Latin) alphabet, numbers and most punctuation can be entered. You may not enter the characters for tilde ('~'), vertical bar ('|') and curly braces ('{'and '}').
Enable this option to set up an administrator password for the camera. The expected login for the Admin Account is "admin". Enter the password and the confirmation password for the 'admin' login in the boxes provided. Click on the Save Settings link to store this and other user settings in the event of a reboot or power loss.
To remove password protection, enter a null (empty) string and then use Save Settings. If the password starts with "$1$", the string is assumed to be an encrypted hash of the password rather than the password itself.
Setting an admin password allows the system administrator to restrict access to the Admin Mode camera configuration tools. The 'admin' login can execute any command in the on-camera /cgi-bin/ directory and can 'set' any property of the camera. The 'admin' permissions also extend to the privileges of the 'user' login.
Enable this option to set up a user password for the camera. The expected login for the User Account is 'user'. Enter the password and the confirmation password for the 'user' login in the boxes provided. Click on the Save Settings link to store this and other user settings in the event of a reboot or power loss.
To remove password protection, enter a null (empty) string and then use Save Settings. If the password starts with "$1$", the string is assumed to be an encrypted hash of the password rather than the password itself.
The user password can only be set if the admin password is set. However, there is no requirement to enter a user password. You may leave the user password blank if you wish to have password-free access to the camera home page and basic functions, provided that you define an admin password to control access to the Admin Mode web pages and advanced functions.
The 'user' access privilege can have access to only the following functions from the on-camera /cgi-usr/ path:
View a JPEG image, e.g. /cgi-usr/nph-image.
View MJPEG video, e.g. /cgi-usr/nph-video?type=multipart/x-mixed-replace
Query the version info (boot version, hardware, firmware), /cgi-usr/version.
Query camera properties (e.g. /cgi-usr/get?exposure, /cgi-usr/get?date)
Enable this option to allow Telnet access to the camera. If the box is unchecked, the Telnet daemon will be terminated immediately. Click on the Save Settings link to store this and other user settings in the event of a reboot or power loss. The Admin Account password can be set to restrict Telnet access by unauthorized users.
Enable this option to place the RS-232 serial port in console mode. This is the same setting as serial_use =console in the API. Leave the box blank to disable the serial port with serial_use =none. Click on the Save Settings link to store this and other user settings in non-volatile memory. Click on the Reboot Camera link to apply the change.
A third serial port mode can be specified as serial_use =accessory. This mode can be used to interface the camera with other devices such as pan-tilt-zoom (PTZ) controllers. In the accessory (transparency) mode, any command sent to the camera over IP on TCP port 8548 will be echoed verbatim on the serial port. The accessory mode can be set programmatically, using the telnet/serial console (l set serial_use=accessory) or by entering a URI in a web browser (http://CameraIPAddress/cgi-bin/set?serial_use=accessory). Click on the Save Settings link and then the Reboot Camera link to apply the change.
Enable this option to turn on Watchdog (health check) functions. The Watchdog Enable and HTTP check boxes should be enabled at all times. Following a firmware upgrade, it is important to check the Watchdog settings.
The Watchdog will periodically check various system parameters. If these parameters indicate that the camera is functioning as expected, the timer will get reset ("kicked"). If the timer does not get reset, the time will expire and the camera will reboot as a self-healing mechanism.
This option is normally enabled. Checks that the webserver is functioning correctly.
Normally disabled. Checks the status of the image compression engine and the image sensor. Enabling this property is not recommended under normal conditions. In the unlikely event that the image sensor fails, the camera may constantly reboot if Watchdog CODEC is set, making communication very difficult.
Normally disabled. Enter an IP address to ping before kicking the watchdog. If communications with the target IP address fail, the camera will eventually reboot. To disable, enter an empty string. Not recommended under normal conditions. The Watchdog Ping feature is only useful if the camera is difficult to access and resetting the camera is likely to fix network connectivity problems.
