The parts for home use are mostly standardised. The DVR has camera inputs for up to 4 cameras (other sizes are available).
The inputs are either Phono (RCA) coaxial connectors or BNC (bayonet type).
The cameras have a video lead which conforms to the CCIR standard and commonly have a phone plug on the end.
You may have the option of audio as well, which are covered by the same plug standard and colour coded (so you get them in the right sockets).
Most common DVRs are sold without the hard drive. You purchase separately and specify the size you require. Once the drive is full it automatically writes over the oldest recording, progressively.
Most hard drives are easily accessible, as a lockable pull out drwer in front.
Some DVRs have other outputs for alarms. Most have a movement recognition program, where an alarm can be triggered if a change in scene is detected.
These are only the basics you have to consider. The rest is up to you, your requirements and budget.
