Hi all ,
After much research I finally bought a decent HIK setup for home (have installed for friends already).
I purchased both the below cameras in 2.8mm guise. They both allegedly (according to spec sheets) have the same sensor and the same field of vision. However in reality the mini bullet has a much smaller FOV.
DS-2CD2045FWD-I - Hangzhou Hikvision Digital Technology Co. Ltd.
DS-2CD2345FWD-I - Hangzhou Hikvision Digital Technology Co. Ltd.
2.8 mm, horizontal FOV: 109°, vertical FOV: 60°, diagonal FOV: 131°
Can anybody please suggest why?
Thanks.
