Many home security companies who offer free house alarm system deals will usually install a basic key pad and sensors on a few doors and windows. In the case of ADT, they will offer a free key pad, 1 motion detector, 3 window sensors and 1 remote.
The hardware isn’t what usually costs the homeowner so much, the cost is usually found in the monthly monitored alarm system service.
ADT usually asks for a 2 year contract around but the monthly usually goes down after the contract is over. Other companies might have you sign a contract that lasts from between 2 to 5 years.
The one thing I’d recommend using when it comes to negotiating your contract is another firm’s home security quote which maybe matched by the company of your choice in order to gain you as a customer.
Regardless of the service provider you choose, be sure to only consider free alarm system deals from a reputable local alarm company in the area with good relationships with law enforcement. There are too many suspect individuals with negative intentions who might simply be attempting to take a look at your property for a future burglary.
