Dear Tony,

The best way to approach that would be to choose the system you like feature-wise. Then contact the manufacturer and get their wiring requirements. What happens is the security world is not so much sticking to any particular standard. Most every manufacturer is playing by their own rules. Therefore it might be misleading to propose any particular type of wiring because the manufacturer may insist (and tie their warranty to) on other kind.

Most likely you'll have to home-run cables from the sensors back to control panel. Also, those wires will be most likely AWG22-24, two pairs, unless you want to drive door locks. Then you should use thicker cables as the loads draw much more current.
