re: A psycho is threatening my family--- Home camera system help UPDATE

Wireless cameras can be good but can go out at inopportune times (our back door camera decided it no longer wanted to connect via wifi right after we left for a week-long trip, but it connects via enet and the other wireless cameras are fine).

If recently put a wireless D-Link DCS-8525LH in one of our windows facing out into the back yard so the wife can watch the birds on the feeders/ground/birdbath in the back yard while she is at work. It has a slot for an SD card for recording (both audio and video), motion sensors, etc and is pretty simple to set up and access via D-Link's site.

If you put one in a window though, be sure to angle it a bit or set it back a few inches as during the night the night-vision camera will pick up its own infrared lights and give you little more than its own reflection in the window).
