Arecont Vision

22-4 Camera Handler Release Notes

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

AV5125IR, AV8185DN.

Considerations

• 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 camera’s 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 set to Arecont camera. So changing these values on web page of

camera will change the values displayed on NVR.

• NVR’s value range can’t cover all the values of the device.

• Camera’s range is -50, 50 and NVR’s range is 1,100. The normalization will be: -50,-41 to 1,10

and -39,50 to 11,100. -40 is not normalized. When the value is read from camera, it is

normalized to 11.

• The range of image quality of MJPEG is (1, 21). So the normalization will be: 1, 20 2, 24 … 21,

100

• Arecont default has blank username and password. Users can use any password or username

to access the camera. But if the password has been set to user admin or viewer, users should

use correct username and password to access the camera. Only by doing “Factory default” can

set the password to be blank. (NOTE: a blank password does not mean ZERO length string. If

user empties the password input in camera’s web page, and saves to the camera, still means

there is a password set.)

• The VideoCodecKeyFrameInterval is the same for all 4 lenses. The default value is set to 30 by

the handler and the camera’s default value is 51. (NOTE: the panoramic camera’s register

address for key frame interval setting is [3:100] not as the individual camera’s [3:21]. The setting

value is the p frames number between I frames, not containing I frame. (For example, if user

wants to set key frame interval 30, the http command should be

http://<cameraip>/set?page=3&reg=100&val=29))

• Models AV8185DN or AV8365DN retrieved by http://<cameraip>/get?model has a “DN” suffix

after the digital model value, i.e. 8185DN or 8365DN, while single lens DN cameras return only

digital model value without “DN” suffix, for example, AV3105DN camera returns 3105, not

3105DN. User can get the model type with “DN” suffix by http://<cameraip>/get?model=fullname

(Confirmed by Arecont supporter). Anyway, what is displayed on NVR should be a full model

type, which means DN camera should have “DN” information in camera model type.

• For H.264 stream, using default bitrate=8192 Kbits and qp=24.
