  5. Hi im planning to install dahua system with nvr 4208-p-4ks2 and 4mp cameras. I saw tha the nvr supports resolution 3840x2160 ,1920x1080 and so on. The cameras are 2688x1520 . The nvr can support this resolution? And the monitor resolution max is the same as the cameras. The nvr has no other option for this resolution of the cameras? Or i had to go with 1920x1080 so the 4mp camera set to 2mp?
  6. If i use ip cameras and nvr poe built in without poe switch it is better to choose cat6 23awg? Or cat6e 24awg?
  7. And also if i use 15.5v power supply for 12vdc 1 amp depending on balun and the distance is less than 50m will burnt out the camera?
  8. On my first picture there are 2 kinds of balun. If i use the second one with 24v power supply will be ok? Because it say from 24-36v the balun can convert to 12vdc. Is there a possibility to burnt my camera? And on the balun that i pictured if i use 23 awg with power supply 12v will cover the slight different of voltage? Thank you

    Mp or starlight

    Somewhere i read that the higher resolution you get the more light sensitivy has is that right. So if i get a 4mp camera non starlight i will be dissappointed about night vision? If you have to install one of those which you will use? 4mp ir or 2 mp starlight? If you have to cover 30-40 meters is better to get a fixed lens about 3.6mm ot get a motorized? Thank you
  15. Hello i have to decide what cameras analog have to install . The options is dahua 4mp non statlight with motr. Lens 2.5-12mm or a 2mp starlight with same lens? Starlight is worth it?
