Each day, more than a dozen homes get burglarized, costing homeowners thousands of dollars in stolen and damaged properties. This is the reason why homeowners spend thousands of dollars each year to install home security and surveillance systems that will help deter would-be thieves. If you're still using an old double lock system, consider investing in a voice alert home protection system. It can monitor and sense intruders in your absence and then alert you in case an intruder does enter your property.
How it works
The voice alert home protection system is a wireless home security device that uses a sensor to 'sense' any physical intrusion or activity within a pre-designated zone or area. It then uses a built-in transmitter to send signals to a receiver or speaker that will record the activity or broadcast it. The sensors and transmitters use PIR or passive infrared technology, which allows homeowners to take advantage of a virtually invisible way to detect thieves, burglars and other unwanted visitors.
What you can expect from a voice alert home protection system
The voice alert home protection system is made up of two basic units: the PIR or transmitter unit and the receiver unit. The signal can be sent from a short distance of about 300 feet to as far away as 1000 feet. The maximum distance that the voice alert home protection system will work depends on the unit, make and brand, so be sure to check.
The system is programmable, which means you can record voice messages that will be played from the receiver's end if the transmitter is triggered. Since most voice alert home protection systems are designed to handle multiple zones or areas, you can easily monitor from a minimum of four zones at one time. Additional zones may be added, provided the system is capable of handling them.
The voice alert home protection system is also designed for outdoor use. It is waterproof and weatherproof, which means it can be installed in backyards, frontyards, garages and patios without worrying about their safety. They can also be programmed to trigger other functions as well, such as switching on patio lights and turning on desk lamps.
Limitations
Although the voice alert home protection system can transmit through common obstacles such as walls, the presence of these barriers can affect the quality of the signal. If there's a wall between both units, for example, the signal can only be strong if the distance between both units is closer. That means a transmitter that can send a signal to as far away as 1000 feet may only be able to muster a strong signal at 300 to 400 feet in the presence of an obstacle. However, this can be corrected by correct placement.
The system also works best if located near windows or doors. If there are metal surfaces or sidings between the transmitter and the receiver, a problem with the signal may also be noticed.
The system can also suffer from false alarms, although this is largely due to placement. The recommended mounting height for the transmitter is about 2.5 ft. to 3 ft. from the ground. The receiver should be mounted at about 7 to 8 ft., depending on the manufacturer's recommendation. The suggested mounting heights are designed to minimize the possibility that the system produces a false alarm.
