American Dynamics Fixed Camera (illustra 210, illustra 600 and illustra 610 Domes)

18-3

• NVR only supports audio in 8KHz.

• illustra 600, add 720p and 1080p resolution for MJPEG stream, change the codec or resolution

of stream 1 will report an error. illustra 600 camera only supports one 720P/1080P stream. If

there is one 720P/1080P stream on the NVR, it is impossible to set another. Please refer to the

camera limitation.

• Auto Exposure switch appears to occur earlier than expected for 720p PAL and 1080p camera.

• The GOP of H264 must be below 120. If the GOP is too big, several seconds are needed to

create a key frame. This will cause a mosaic image effect when opening the NVR if it is not a I-

Frame. It is suggested to set the GOP size the same as the frame rate. On the camera, the

default factory GOP is 30 for NTSC, 25 for PAL, it is not recommended to change this.

• When changing the FPS, the corresponding RTSP stream will restart. This may result in a minor

video loss dependent on the GOP size configured, because the video needs a key frame.

• It is recommended to configure the camera within the camera FPS limitations. If the parameters

exceed the limitations, the camera performance may be affected.

• Rebooting the camera to factory default can resolve the camera performance. Once this is

complete, reconfigure the camera within the camera FPS limitations.

• NVR does not support changing the quality of H264.

• Although the NVR does not support changing the quality of H264, this can be managed through

the camera web GUI. To support dual streams, it is recommended the interval between changing

codec/resolution should be greater than 30 seconds. Otherwise the camera may keep rebooting.

• Dry contact messages that have been lost on the NVR maybe received if the camera is set

beyond camera FPS limitations. Please refer to the camera FPS limitation document.

• When changing the codec of steam 1 in an NVR that has dual streams, the error “unable to

determine stream 2 – malformed request” will be reported. When the “back” button (refresh in

the web GUI) is clicked, the codec will have changed to the configured codec. This is a limitation.

• If Motion Meta Data is enabled, changing codec/resolution of stream1 or stream2 after the

camera reboots, the Motion Meta status will be disabled. This is a limitation.

• If the default exposure is configured on the illustra 600 or 610, a 2 to 3 second video freeze will

be experienced as the camera changes mode from day to night. When the available light caught

by the camera lens drops sufficiently, the camera changes from Day mode (color images) to

Night mode (black and white images). This freeze is related to the time it takes the camera lens

to readjust to the light difference when it is set to the default exposure rate and the effect on the

NVR as the mode changes over. A workaround for this is to increase the exposure setting. This

is a limitation.

• For resolution/frame rate/quality limitation, refer to the camera FPS limitation document.

• Video and audio may become out of sync when navigating playback to specific times on the

victor Client clips.

• If the codec on the camera primary stream is MJPEG, when this camera is added into a NVR,

the camera will need to change the codec to H264 and reboot. The camera will be offline for

about 20 seconds

• Wrong video timestamp will make NVR create a lot of sessions and have a minor video loss in

playback.

• If a user changes the rate control of an illustra 210 model on the Camera Web GUI to VBR it

may cause a pulsation effect on the H264 stream when using default resolution, FPS and quality

values. The Default for the Rate Control is CBR.

• The Factory default values for the illustra Camera models are:

1 2 ... 42 43 44 45 46 47 48 49 50 51 52 ... 107 108
