Definitely consider zoneminder. I&#x27;ve used it with Foscam and Crenova ip cameras with good results. The cameras I got were $30 for a basic dome and $70 for a pan-tilt.<p>However, if you do decide to go this route I would be prepared to put all of the cameras on a separate network without access to the internet or the rest of the lan. They are literally little linux machines that shouldn&#x27;t be trusted. Setup a firewall that ensure they can only connect to the zoneminder server.
