8 channel NVR

2 IPC ‘s

 

I have one camera recording and working fine.  The other one is identical, and in Setup, Camera, Remote when I Device Search, I can see it.  I Add and it shows up below  I Modify it and set the correct password, but the Status remains with the Red X for Connection Failed. 

 

I can log on to the second camera itself via internet explorer no problem, see video, etc.  Both cameras are set up the same with different IP’s.

 

Ideas?

Check the firmware on those cams and see if it is the same on both. Also the cabling might be bad. Is it pre-made or custom? Check your termination.

1) I would try another IP address to see if that helps.  I have seen cameras with very close IP addresses have problems.  2) Try defaulting the camera and get it working with all defaults first before you make any changes.

The IP’s are 1 off:  192.168.1.162 – Camera 1, works fine.  192.168.1.161 – Camera 2, no problem connecting via internet explorer from a laptop at any point in the network, NVR won’t connect. 

 

Cabling is “custom.”  Network:  NVR to router to LOCOM5 pair to switch (Camera 1 attaches here) to LOCOM5 pair to router to camera.  CAT5e cable between non-RF components.

The cameras are identical:

SDK version 4.0.0.2

Kernel version: NVSS_V6.8.3_20140407

Web Version: 5.0.0.28

Factory ID:  slightly different

Access moudle: onvif_v2.4.0_20140723

 

Changed the IP to *.148, rebooted the camera. No change in behavior:  Can connect to the camera with IE, on the NVR, Device Search finds it, add, edit to set PW and change the port to 8080 (same as the other camera), no connection.

OK, I found a work around:  Set the camera PW to admin, then run the Device Search, Add, edit to change the port to 8080.  The NVR now “sees” both cameras. green Status and it is recording both channels.

 

I don’t like leaving the camera PW as admin.  My network is air gapped from teh intr4w3bz, y0, but I’m still not real comfortable with that.  Is this a bug inthe NVR software?

The NVR may have a requirement of 8 characters or less for a password, so a long password may have been the issue.  Always get it working with default settings and then go from there.

The PW I was trying to use is 5 characters, and it’s the same PW that the other camera (Camera1) is using successfully with the NVR.

I sent you an email with a link to newer firmware than what you have.  You can try that first.  If you want me to log in and try your password, I would be happy to do that.

I upgraded the firmware to what you provided in the emailed link.  I don’t see any change in the Version Information page.  Kernel version and web versions are still the same as listed above.  And, the PW behavior is also the same.  That is, set PW to anything else on both the camera and the NVR besides ‘admin’ and they won’t talk.

I didn’t notice, but the Access Module is now: onvif_v2.4.0_20140904, so that’s different.  Behavior is the same.  I suspect the NVR’s code.

To my understanding changing the password of the camera will not affect the ONVIF connection. Also I believe the port will but I’m not sure where to change the 8080 port, do to the fact that you can access the gui of the camera if you add the 8080 at the end of the IP address when using IE to access it. It will bring the logging interface anyway, some how is redirected to 80 at the end. The admin username and password is lower case just as a side note. So is everything working I guess?

I found the settings to remap the port, but I’ve left that alone.  It is all working on 8080 now.  The only thing is that I can’t change the camera password off of the default value and have it work on the NVR, but only on Camera 2.  Camera 1 works fine with a different PW.  That’s a securitiy hole, but I have this network airgapped from the internet.  If an update for the NVR code becomes available, please let me know.
