Home Cctv

I have 2 wireless cameras and using thrm for home security do i need a time lapse vcd or a regular one and i have a pvr im not using can i hook that up too cameras i tryed but it didnt work dont know what channel they would go on

I’m looking for some good quality home security system(DVR+Color Cameras). I need most capabilities for the DVR like optimized storage, 160GB space, motion detection, good quality, connection to TV/Monitor. Cameras connect to DVR via BNC connector and colored with night-vision.
Suggest any with good balance between price and quality?
