Wansview NCB541W delivers corrupt JPEG data

[Brian de Halma]

Hi everybody,

first of all I have to admit, that I'm not very experienced with Ubuntu (Using it (V. 12.04) just as fileserver). Nevertheless I was brave enough trying to use Zoneminder as surveillance-server. The Installation process did work smoothly, but now I'm stuck connecting our camera (Wansview NCB541W) to Zoneminder. Here are the settings I used so far:

Name: C-Cam-01
Source Type Remote
Function Monitor
Enabled
Maximum FPS 5.00
Alarm Maximum FPS 5.00
Reference Image Blend 7

Rem. Prot. HTTP
Rem. Meth. Simple
Rem. Host Name <username>:<password>@cameraip
Remote Host Port: 81
Remote Host Path: /videostream.cgi
Remote Image Colors: 24 bit color
Capture Width 160
Capture Heigth 120

All the other settings I left as they were.

What I achieved was, that the camera log-file shows that Zoneminder accessed the camera. But in Zoneminder itself there is nothing more to see than a hole lot of (error) messages in the log-file:

Does anybody have an idea what the problem is and how it can be solved?

Google is your friend (and the forum search option too):

Thanks,

Unfortunately only partly. These error-messages are annoying, so its good to know a way to get rid of them. But the main problem is still unsolved: the monitor won't show a picture and I don't know why. It seems Zoneminder has access to the camera and it gets pictures, but can't process them properly.

Hi everybody

I solved the problem! For those who have the NCB514W and failed implementing it into zm - here my solution:

The mistake was, that I didn't add user and password in <host path>. So the complete settings which at least work on my system are:

General
Name: <Your Cameras Name> (for example:My_Camera_01)
Source Type: Remote
Function: <choose what you want zm to do>
Enabled: Yes
Maximum FPS: 5.00
Alarm Maximum FPS: 5.00
Reference Image Blend: 7
Triggers: n. a.

Source
Rem. Protocol: HTTP
Rem. Methode: Simple
Rem. Host Name: <username>:<password>@cameraip (username and pw --> camera)
Remote Host Port: <the port your on which your camera is listening>
Remote Host Path: /videostream.cgi?user=<username>&pwd=<password> (username and pw --> zm)
Remote Image Colors: 24 bit color
Capture Width: <Width of camera settings>
Capture Heigth: <Height of camera settings>

All the other settings I left as they were.

Good luck!
