Review on PTZ Pan Tilt Zoom Bullet Security Camera : Motorized Lens & Housing : 1080P 2MP@30FPS, 2.8-12Mm Auto-Focus Lens, IR LEDs, IR-Cut, WDR, Motion Detection, DNR by Brent Borseth

I originally got a DVR security camera setup to keep an eye on my kids but had blind spots so I got 2 of these they installed fine everything was good. Then i ordered 2 more I hooked them up to my controller to program them and they worked fine but when I replaced the cameras they refuse to respond. I'm not sure why I have replaced the power line with 14 agw the RS-485 lines have been replaced and still they don't want to work I programmed them #4 and #7 but for some reason #2, #3 #5(p&t base) and #6 (p&t base) all work fine but these last 2 just power on and then reset to 0x0 with no control on pelco-d but pelco-d only
