How can i check existing security system cameras
Hi I just moved into a home and i see outside 4 camera outside the home. I have found what looks to be the wiring but no dvr box. If i get a box and connect will old cameras just start working??? No idea about how it works. Also i have a dcs monitoring box and 2 keypads. How do I re hock that up. Or when I call a monitoring company they do all re connect for that part.
