I’ve got some Smonet cameras (from Amazon) that connect wirelessly to an NVR (network video recorder).
Likes:
Not that expensive.
Easy to install.
Impressive picture quality (day and night).
2TB card in NVR records several months of continuous video from 3 cameras.
Good customer service.
Able to view remotely over the internet via an App.
No need to subscribe to an internet cloud service.
Dislikes:
Unable to disable built-in infrared LEDs. I would like to be able to use separate LEDs that don’t attract insects to the camera because you end up having to clean spiderwebs off the camera lenses regularly during summer. Also, I have one camera behind a window and the LEDs reflect off the glass at night.
The connector on the camera leads are too big meaning you need to drill large holes in the wall for the power cable.
