For burglar alarms, homeowners can also ask their contractors to wire their house in such a way that when the wires are tripped or cut in any way, the alarm will go off. However, it is more typical to see motion detectors now since technology has improved alarm systems. These motion detectors act much like wires but they use infrared beams instead of wires. Once these beams are crossed or disturbed in any way by some object, the alarms will go off. Motion detectors are not to be used in a house that is full of pets. Detectors are a great gadget because they can also be connected wirelessly to other components like wireless cameras and computers. LocksContractors know that every house needs good locks. These home security system products for contractors are great to offer homeowners. Electronic locks are becoming more commonplace in areas around the world where house break ins are just as common. Electronic locks are useful in that they can be controlled only by those who know their combinations. This means that everybody else who cannot use the electronic lock will more than likely set off an alarm.

The former is a wireless connection to the monitoring station, making it immune to power outages or someone cutting a cable. It is limited, however, with regard to transmitting large quantities of video, so many cellular primary systems incorporate broadband for video. Broadband primary services, on the other hand, have cables running down the side of a house that can be cut, thereby disabling the system. Some services offer cellular back up should this occur. Look for a home security system with a full line of wireless peripherals, including modules for controlling lights and appliances, thermostats, cameras, motion sensors some can distinguish between a pet and a person, water sensors, and glass break and vibration sensors. Look for long life battery power, too. Lithium sensor batteries, for example, can last three to five years. When they do run low, the system lets you know well in advance. Choose a controller with back up battery so the system will stay active in the event of a power outage or if the Internet is down. If you will be installing smoke alarms you’ll need the extra power of a 24 hour battery back up, not the 4 hour back up offered by many manufacturers. THE COST FOR SECURITY There are two costs to keep in mind when shopping for a home security system.
