Infrared wifi ip camera to monitor rat in the night

[zio_mangrovia]

I need outdoor wifi IP infrared camera to arrange in small techincal room (3x2x2 m) and to save video events in the night.
My scope is to intercept rats and angle of view must be wide because room is small, I wish good good camera lens to register (720p or 1080p) events in the NIGHT.
I don't know if It exists the automatic mechanism which permit to save videto internal SD card if wifi signal was not enough sufficient.
Can you suggest me some brand or models to buy please?

You might want to check out the below models from Hikvision.

DS-2CD2142FWD-I 4MP dome camera
This camera has a built-in microSD card slot, and is available in a 2.8mm focal length which would give you an approximate 105° horizontal field of view - very wide.

DS-2CD2152FWD-IWS 4MP mini-dome camera
This is a camera from the same series as the one above - it's much smaller though. It has a built in microSD card slot, but it also has WiFi capabilities, if wireless connection is essential for your application.
