American Dynamics Fixed Camera (illustra 400 series)

17-2 Camera Handler Release Notes

Limitations

• The camera will reboot when changing codec (audio or video), resolution, frame rate, key frame

interval, video quality, audio volume, enable audio / audioin and any other audio / video

properties. The reboots will take about 20 to 30 seconds.

• All audio and video streams will be lost when the camera reboots. All audio and video streams

will then need to be re-established.

• When the camera is rebooting, video and audio properties may not be available to get / set new

value.

• Due to camera internal resource contention, both profiles (streams) must have the same

resolution. If profiles (streams) are set to obtain different resolutions the requested FPS will not

be obtainable for MJPEG.

• To achieve optimal H.264 Motion Detection results, the recommended settings are:

• Stream 1 is H.264, 30fps, D1 or D2 resolution, default quality

• Stream 2 is MJPEG, 7 fps, CIF, default quality

• For some properties’ value are retrieved from camera itself (e.g. resolution, quality), result in that

when user adds the camera, the return value is not the default value defined in the NVR, but the

actually value in camera.

• VideoCodecKeyFrameInterval is not supported by the camera handler, but the user can change

it from the camera web page.

• For AudioInputVolume, the microphone input and line-in input have different ranges.:

• Microphone input:

• A setting of ‘low (1)’ is 20dB

• A setting of ‘high (10)’ is 26 dB

• Line-in:

• A setting of ‘low (1)’ is 6 dB

• A setting of ‘high (10)’ is 18dB.

• Due to camera internal resource contention, changing the resolution or quality or bit rate may

affect the frame rate performance. Please refer to camera limitation.

• Changing the video codec/audio codec may cause the RTSP service in the camera to crash,

and can’t get the video/audio streaming, the workaround is to reboot or power cycle the camera

• With camera firmware v2.20, the FPS selections for the MJPEG codec from the camera web

GUI shows only "3,5,7,10,12,15,30" for NTSC and “3,5,7,10,12,15,25" for PAL. This, however,

does not affect the FPS selections from the VideoEdge client, which remain supporting 1 - 30 for

NTSC and 1-25 for PAL.

• To meet the single stream fps, the user can enable dual stream on NVR, configure the stream

codec/resolution/fps/quality for Stream 1 and then configure Stream 2 to lowest

resolution/fps/quality. Once Stream 2 is configured the user can disable Stream 2 on the NVR.

Alternatively the user can access the camera’s web GUI settings to change stream 2 to the

lowest/resolution/fps/quality.
