Garage Alarm

For my electronics course, I need specifications for a company garage alarm system (it can do, not what he used). that's not all my classes so you do not do it for me, it's just that I find nothing to do with burglar garage.
Please, any help would be greatly appreciated.

If you mean a garage door sensor for an alarm system, your search is over:

If, on the other hand, you mean more generalized protection for a garage is more complicated. Some alarm companies will sell PIR motion detectors (PIR) for the garage, but it's a bad idea, because hot weather could miss a PIR intruder (and here is a link that explains why):

So the best way to protect a garage (in addition to the sensor referenced above for the garage door) is a combination of wireless sensor normal door / window and / or glass break sensors, depending on configuration.

Our site has a ton of information on these sensors, hope this will be useful for you all.

If you look at sites for companies like ADT Security Home you can find the specifications for what types of products they have for Garages - including how they work. Regarding alarm systems garage door will also work separately - companies like The Home Security Store LifeShield and manufacture products that could meet the needs of an alarm garage.
