Unstable network using IP camera

Recommended Posts

Hi All,

 

I had an issue which is my vms randomly unable to fetch view from NVR.

Probably due to the traffic to the NVR was overload.

 

i use vivotek cam with dual streaming

stream 1

H.264

2mbps

25fps

 

stream 2

mpeg

512kbps

15fps

 

In order to encounter this issue,i had setup the environment on labs & try enabled udp multicast on camera & network to reduce the traffic overload. The finding is :

 

NVR unable to records the streaming while camera in black & white mode. & randomly disconnect.

 

Does anyone had encounter this kind of issue?

Hello. Simplest thing to try is placing the NVR and camera antennae in different positions and see if that improves stability. Other things to consider are to move the NVR closer to the camera (or at least the antenna). You might check with the manufacturer and see if they recommend some sort of signal booster or repeater that can reside between the NVR and camera.

Hi GadgetAssistant,

 

Thanks for the response, btw, what is meant by cam antenna?

All of our camera was using Poe for the camera, which means it in LAN network environment.

I think it is not the distance issue, since all cat6 cabel in our labs environment are less than 2m.

 

While onsite, all of the port trunk were using fiber cable. Cat6 cable are less than 100m.

PoE extender were equipped for those cable that are more than 100m.

Oh. Sorry I assumed this was a wifi setup. My next guess, in your case, would be that there may be an issue with power to the cameras. The fact that the issue seems to be exacerbated when the LED's are activated also points to that. If the cameras have a power input separate from the POE connection use that from a power outlet close to the camera, If your cable run is really long, attenuation may prevent enough power from getting to the camera. If your cable run is not very long then try a new power adapter for the NVR.
