ibraba 0 Posted May 25, 2014 Hello to all of you I have some troubles with my IP cameras. It's a system with 6 cameras ; and the nvr could not detect more than 4 cameras.The 2 others were a bit far from NVR (nearlly 200m). Then I've used FIBER OPTIC cable; the NVR happen to detect 5 cameras and the 6th is not detected yet.I'm a bit confused and stuck. Can someone tell me what's wrong with the Installation. NOTA: There are 4 speed domes and 2 fixed cameras. Share this post Link to post Share on other sites
seriousfew 0 Posted May 25, 2014 I would make sure first of all that there's nothing wrong on the Physical layer. Basically make sure that either the cable the last camera is connected to the network isn't faulty. Share this post Link to post Share on other sites
ibraba 0 Posted May 25, 2014 Hello sir All the cameras are good. Please what do you mean, by "Physical layer". I've launched detecting process many times,but I don't allways detect all the 6 cameras and I don't understand what happens.Right now I get only 5 cameras. Best regards.

thewireguys 3 Posted May 25, 2014 What type of fiber are you using? Single mode or multimode? Did you use pre terminated fiber or did you term it on your own. How are you converting the fiber to ethernet? Share this post Link to post Share on other sites

Make sure all of your cables are good. What are you connecting the cameras to? A PoE switch? Make sure that all cameras are connected to PoE ports on the switch.

ibraba 0 Posted May 26, 2014 Hello, thanks for your reply The connections are made by another technician,he told me the fiber is Multimode type.He used Fiber-RJ45 converters for both side (ie connecting the camera and the main switch). Best regards Share this post Link to post Share on other sites
