I am choosing between these three models:
4526: http://overseas.hikvision.com//uploadfile/image/20150413111741603.PDF
4535: http://overseas.hikvision.com//uploadfile/image/20150417022147307.PDF
4585: http://overseas.hikvision.com//uploadfile/image/20150422082615905.PDF
The camera will cover my back garden, 20 x 20 ft, 90 degree view from a corner. There is no direct lighting but it is far from pitch black as it has some indirect light spill from a few far-away street lights.
The way I see it, it's a trade-off between low-light performance and resolution. It would have been nice to have the high-pixel density of the 4585 in order to meet ID requirements (500px/m) up to 16 ft. On the other hand I suppose the Darkfighter's performance would be superior at night, but by how much, and enough to go for 2MP only. High FPS is another bonus with the 4526. Perhaps the 4535 is the golden compromise with respect to these parameters with a motorized lens to boot?
4585: High resolution, medium light sensitivity, no true WDR, low FPS; or
4535: Medium resolution, medium light sensitivity, true WDR, medium FPS; or
4526: Low resolution, high light sensitivity, true WDR, high FPS.
What do you guys think?
