Reddit mentions of Hikvision 4MP DS-2CD2042WD-I IR PoE Network Security Bullet Camera 4mm Lens

This one from Hikvision works pretty great!

That GW Security camera looks fine.

I recommend POE IP cameras though like the following:

If you got to have indoor WIFI then something like this Hikvisiion will do all right, but remember WIFI can be flakey at times so you may experience some periodic drop in the stream/recording:

One MAJOR thing to be aware of, with any security camera system, make sure you set up the cameras on a separate VLAN and/or separate physical LAN from your other home network and have firewall rules in place to deny that VLAN and separate physical LAN from communicating to the outside and do not let any external device access it from the outside. If you need access remotely to the cameras, setup a VPN server to have secure access into that camera network. Pretty much all of these cameras come from China so, you want to protect yourself not just from unwanted random outside snooping but also from the cameras calling home in the event there's hidden foreign government backdoors/spyware.

I have a Synology ds 418 and a hikvision camera. You can record with the synology software for free (no cloud) for 2 cameras i think
