Ok. I will wait. I am curious to know how much diference it's between this two in terms of the angle and the distance from left to right at 4 m ahead.

I need help to choose an IP camera. I looked at HIKVISION DS-2CD2032-I 3mp lens 4mm. If someone can post the angle view diference between the DS-2CD2032-I 4mm and one with 3.6mm (DAHUA IPC-HFW2100). I found on youtube a movie with diference between 2.8-3.6-4-6 mm. But the angle view depend also by sensor. I need a video sample from these 2 camera, take from the same position. I want to install this camera in front of a fence with lenght of 12 m and at a distance from 4 m, in the middle. I want to know how much of the fence these camera can see. Thanks.
