Hi friends, 
  
i just installed my 16 camera cctv system in my 2.5 cre farm house.  
2mp ip hikvision (2020 f-i) 
16 channel nvr 
  
my question is since its a huge farm house, how do i get best nightvision. i read that lighting is really important but how do i setup the lighting for thr camera ?? 
  
should i buy floodlight and place them above the camera?? i can get a 20 foot pole and place the 100w led light above the camera ?? 
  
as of now i have a camera facing in a direction and light on the ground in the field of the camera which is not giving good night vision. all cameras are at a height and where ever there are pointed, lights are installed there. white led bulbs so the bulb is really shinning on the screen. 
  
 the cameras i have are really expensive. ive spent more than $3000 on the whole setup so i dont mind spending another $300 on lighting if that helps. 
  
please help !! 
thanks !
