27-4 Camera Handler Release Notes
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 for H.264 is (17, 36). And the normalization are:
36 5
35 10
...
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®=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,
not3105DN. 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.
• For saturation range from
camera to NVR, its mapping relationship is:
1 0
2 20
3 40
4 60
5 80
6 100
