Arecont Vision

27-3

• Due to the camera firmware issue on AV8185DN, the camera stream may restart on the NVR.

• Due to a camera hardware limitation, for AV8185 and AV8365 cameras, the sensor size is

1600x1200, so the NVR resolution setting is 1600x1200, but it streams at 1600x1184

Known Issues

•

• NVR receiving H.264 frames with timestamp prior to last one received for cameras AV3105,

AV5105, AV8365, AV10005. (Arecont ticket: TECHSUP-20512)

• A number of Arecont cameras have been identified as having firmware issues where cameras

may unexpectedly stop sending Frames for a short time (3-7 seconds). In some instances this

will trigger a lost video alert. Cameras where this issue has been observed are AV3115DN,

AV5125IR, AV8185DN. (Arecont ticket: TECHSUP - 15613.

• AV8185, AV10005 series - observed 7 seconds of video loss on camera stream several times

this is a firmware issue. (Arecont ticket: TECHSUP-15751).

• For some properties' the values are retrieved from the camera itself (e.g. resolution). When an

Arecont camera is added to the NVR, the return value is not the default value defined in the

NVR, but the actual value in camera.

• For Arecont's MJEPG version cameras, the D/N camera does not return suffix DN for the model.

So NVR will not get D/N option.

• On Internet Explorer, if changing the default user name and password, the camera may not be

accessed successfully.

• Due to camera firmware defect, the camera does not return the full model name, the NVR

cannot support the daynight and auto Iris settings for all the Arecont cameras. The settings can

be configured in the settings via the camera web GUI. (Note: Please refer to the Arecont Vision

Camera Release Notes published by Arecont Vision for additional information.)

• On the AV8185 camera, the camera continually rebooted itself during daytime hours. This was

caused by the NVR smoothing mechanism.

• Higher video bit rate may occur under low light conditions, which may cause video loss.

•

Special Points

• It is recommended when the camera is added to the NVR, not to change any property

parameters on camera web GUI.

• Arecont only support two resolutions, one is half, the other is full, and we will convert it to width x

height according to the actual picture size.

• MJPEG over RTSP is not supported.

• Video Codec Properties are all set to DB. The properties on the camera web page are not used,

and these settings are for default stream fetching by web.

• Internet Explorer may cache the history data, if Internet Explorer is used to get the properties of

an Arecont camera by the direct URL (such as http://<ip>/get1?brightness), a page refresh

should be used to get new data.

• Brightness and sharpness are retrieved from the Arecont camera GUI. There for if the user

changes the value on the camera GUI it will change the values displayed on NVR.NVR's value
