Bought a driveway alarm system.
I have a very long driveway and wanted a good alarm system. The two basic requirements were that it had to be wireless and had to go at least 1,000 ft.
I finally found this product, the Di2000, the Driveway Informer by Security2020 and it is awesome.
The only con I can say is that they offer flat rate shipping of $4.95. They ship it out FedEx ground so it took at little over 4 days (from order) for it to arrive. I guess I would have though it would come a little sooner. For $4.95, I guess I should not complain.
