A lot of people prefer wireless security, and honestly it’s one place where I agree wireless is a good option. However, in larger homes you can have wireless range issues.
So if you have the time, it’s still a good idea to prewire for your security system. At a minimum, you need to wire Security Keypads for power.
Security Keypads take (1) 22/4. I prefer to place the Security Keypads above the light switch for the room, and at a height of 5’, but you can place them anywhere you like.
Motion sensors take (1) 22/4. You want to place the motion sensor at a height of about 7’, and usually in the corner of the room. Make sure it’s an area that won’t be obstructed by media cabinets, or other large furniture. If you have cats or medium sized pets, you can’t aim the motion up the stairs.

Glass Break Sensors
Glass Break Sensors take (1) 22/4. You want to place these in the ceiling. Glass breaks cover windows within 15’, and that are in clear site of the glass break.
Door Sensors take (1) 22/2. This is a little different, you are going to pull the 22/2 through the door jam. There’s a couple options, but to keep it simple, use a 3/8” drill bit, and drill out a hole in the door jam to pull the wire through. You’ll use that hole later to slide your door sensor back into.
Window sensors take (1) 22/2. These are the same thing as door sensors. They have variety of types, but they work the same way as door sensors. It’s possible to recess the sensors in the track of the window, but it’s different window to window. It’s almost easier to just plan on using a surface mount sensor. The kind that stick to the window frame, and window.
You’ll want to pull an 18/2 or a (22/4) to a location in the home for a Siren. You can pull multiple siren locations if you like.
Most Security systems don’t integrate with your Smoke alarm system. This is largely due to the fire code. Smoke alarms are designed so that if one smoke goes off, all smokes go off. This is one location where you’re likely going to do a wireless smoke detector after the install. A few security systems like HAI, and ELK support hardwired sensors. You should consult with your electrician if you plan to do this.
