Electronic Alarms and Home Security Devices - DIY alarm

I would like to make and install a garage alarm system.
Would it be easier to just buy a alarm system and have them install it than for me to buy all the pieces and make my own.

Many of the alarm systems are available as "kits" and "fast-packs" that contain all of the essential parts with the exception of the hardwired zone contacts.

The more important question is how willing are you to tackle the installation and programming yourself. As you can tell from reading this forum, surprisingly simple things give people fits where programming is concerned.

I can understand what you mean and it makes me wonder myself.

I know a guy who doesn't use his alarms now because it is a hassle to have to program in and out all the time.

Is there a simpler DIY way to not even have a program key board and maybe a hidden switch or key switch maybe with motion or infrared detectors inside the garage ?

I installed an alarm system in my house and shop about a year or so ago. Running the wire and hooking up the devices was easy, programing the keyboard was not - probably the hardest thing I ever did. Once finished it is easy to operate, on mine you just push the arm button on the keypad to activate and punch in your 4 digit code to deactivate.

I purchaced mine online. The "complete kit" was about $100 and maybe another $100 for everything I added on.

Nearly all systems require at least one keypad for the system to work. You can still set a zone as a "keyswitch" input to arm and disarm, if you wish.

The setup is the hard part. The day to day arming and disarming is pretty straight forward with most systems.
