VideoEdge NVR 4.1 Release Notes
30
8200-2735-07 D0
AV8185 series - observed 7 seconds of video loss on camera stream several times during
soak. This is a firmware issue. (Arecont ticket: TECHSUP-15751)
For some properties‟ values are retrieved from the camera itself (e.g. resolution), result in,
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 Models AV1300, AV2100DN etc. (MJPEG VERSION), the latest firmware version is
64328 (AV2100 64327). When the camera is set a password, and get JPEG stream by HTTP
using incorrect password, the HTTP response is missing one CRLF, which causes the
GSTREAMER to get stream failed.
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.
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:
o -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 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
o http://<cameraip>/set?page=3®=100&val=29))
Models AV8185DN or AV8365DN retrieved by http://<cameraip>/get?model has a “DN” suffix
after the digital model value, e.g. 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:
