  1. Same reason I am buying them from china in the first place, and not from some distributor in my country: It will be presumably 30-50% cheaper from the original manufacturer, than these other suppliers. Right?

     

    If you can find the true manufacturer, they will not deal with you for less than 10 units anyway. More likely 50+


  2. Chances are neither are the original brand.

     

    The practice of OEM allows Asian manufactures to sell much larger volumes by branding them for multiple companies.

    While the product may be OK, the support on this kind of sales is often 0

     

    If you buy from a recognised name (a manufacturer) it will often cost more but you will get on going support.

  3. 800m on cat5 UTP is a long way and I suspect the voltage drop you are getting on this cable is going to be too much.

     

    If you have a multimeter, measure the voltage at the camera when it is meant to be running. If it is lse that 11.5 volts, that is the problem.

     

    Because you have 2 nice IR lights and the camera to power up, UTP is not a good option.

    Can you move the power closer to the camera and only use the UTP for the video?
