oturva 0 Posted October 24, 2016 We try to use CantonK poe ip-cameras with Tvt's nvr, but there is some problem and manufaturer cant help us. Camera works only when we use external router and external 12v power, not with poe or straight connected to nvr (we are tried with cross and straight cable). Any help? Can someone recommend any good quality oem manufacturer whose poe ip-cameras work with tvt nvr? I know there is always option to change other nvr brand but i like Tvt's dvr's and nvr's quality and software too much to change it. We are also tried CantonK own nvr but it's quality is not good enough. Share this post Link to post Share on other sites
almelst 1 Posted October 25, 2016 Are IR LEDs on camera glowing in the dark while supplied by PoE? If so, everything is OK with PoE power supply Try connecting PC to Cantonk IP camera via router and set IP address to DHCP option. Then connect it to the NVR.

Yes, power comes to camera and leds are on. We are changed camera to use DHCP but still no picture. Now nvr finds cameras ip address but still no picture. Everything works fine when we use external router and 12v power. Any help? Share this post Link to post Share on other sites
almelst 1 Posted October 28, 2016 Check protocols in camera and NVR setup. They both should be the same, ONVIF. Share this post Link to post Share on other sites
