  1. If i use ip cameras and nvr poe built in without poe switch it is better to choose cat6 23awg? Or cat6e 24awg?
  2. 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?
  3. 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
  10. 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?
  11. Hi what is the requirment for choosing between those two cables cat6 23 or 24 awg? Is it how long it will be? We are talking about cctv system analog cameras
  12. So i need 0.3 amp for 3 cameras that goes 1 amp approx. And 1.25 amp for the motorized camera. So if i get 4 way box 5amp. my 4th camera should be ok? Because im 5 amp / 4 way is at the limit of my 4th camera amp.
  13. So you recommeded not use splitter but the box? Is it ok to have more amper to each channel that the camera needs?
