I have an older hard wired B&W system. It came with 2 cameras and a monitor. Harbor Freight sold these systems and they would go on sale for 50. Now they have color ones with flat screen monitors. The monitor on mine has a switch where you can set it to either camera or to altenate at an interval between the two. I assume the new ones do that too. I use it in my staging and it works great. Basically I only need one camera so the second is superfluous.
I dont' know about how hard the wifi are to set up and use. These hard wired ones are very simple. And for the price you could get more than one system if you wanted more than 2 cameras. The colors seem to go on sale now for about 60 at Harbor Freight stores.
