I have connected 16 nos 2MP IP camera to a 32 Channels NVR, the location is double storey ship lot in Tawau.

 

+ 24 port Switch + DC 12V 20A(F) Power supply

 

Problem :

1. Everything working fine, after the installation.

2. However, few days later Some of the camera not link and unable to see from the monitor.

3. There are 2 camera out of order.

4. Re -changed the camera and is working but however the 4 same camera cannot see again.

5. The Switch is on, light is blinking

6. Restart the Power Supply and the camera are working,

 

I want to know what contribute the above problem ?

 

Am I using the correct power supply ?

 

Thanks

Running short of electrical power could be main cause.

You mean the power supply that I use is not enough ?

The camera which unable to see is always the same.

Camera model?

how are you running power to the camera? Over what cable?

Did you properly crimp the cable using 568 standards?

Running the power through power supply, AC cable

I am not sure about the 568 standard, I will need to check with the CCTV installer.

The problem is it started from the cabling ?

It is possible that the cable run is at or beyond 100 meters, that will cause all sorts of weird issues.

i want to know which products you are using for the cameras and nvr?

I want to know if you have tried to view the camera on the web interface

 

Nevertheless you could troubleshoot the following:

ok, As regards the cameras not showing on the display

 

1. check if the cameras are still powered by physically examining the cameras while connected to the switch,

2. if you are using a POE switch, connect your laptop to the switch and try to see if you can assess the camera through the web interface

3. Check also if ip address of the cameras is not conflicting with another

4. Test the cable.

5. if everything seems ok yet its still not displaying images but if you can find the camera on the nvr list, then I suggest that you also check the nvr configuration, if it was hikvision , their NVR usually have where you can specifically assign a camera to a particular display channel (menu-configuration-live view)
