I have the DS-2CD2T46G1-2I 4MP installed since 2 weeks ago, and I must say it is just amassing. It is my fourth camera from Hikvision. Daytime video quality is great, night time also very good. Only enabled intrusion detection and alert to email. It makes no mistake distinguishing between dog and human for example. Once you go acusense you never go back Country: Romania.
Picture beside DS-2CD2020FI. It is a monster.
Define better? 8MP musst not be better, its based what you gonna do with a camera, and whats there goal. If you wanna look only a door entrance with 5m distance, 2mp is enough. If you wanna look a parking lot or a company ground, 8mp are good for details. If you wanna do a alarm system with cameras, EasyIP 4.0 or Deep In Mind is the key.
So there are many details to think about it. Distance - Range, IR Range, Height, fov, Detection Functions, Optical Zoom for more Details and so on.
