Perfect Solution for Large Parking lots or Truck yards
Every CCTV installation company comes across this kind of clients, where the options are limited or very expensive.
For example a Large parking lot, huge open area to cover but power out lets or it is very hard to run cables from each camera to the DVR or NVR.
We found the right camera,
Vivotek a few months back released a bullet camera that does exactly this. It has a PoE in, and then another port for PoE out to connect to another camera.
Vivotek IB8367-R $486.00/ea.
As for the NVR, I would recommend the Vivotek ND8322P: http://download.vivotek.com/downloadfile/downloads/datasheets/nd8322pdatasheet_en.pdf
It is awesome, run only one cable from Camera 1 to 2 and then 2 to 3 so on and so forth.
