I use Reolink cameras. There are several models to choose from. Many can be connected via WiFi or LAN, though some are only one or the other. Most of them have a micro SD card slot for recording or you can get an NVR (network video recorder) to record and playback footage from several cameras (optional). You can view them over your phone, tablet, computer or, with the NVR, on your TV. All of mine do infrared during low-light conditions. Many capture sound as well and some even have a speaker so you can talk to the chickens (which, btw, really freaks them out ).
