Voice Alert Systems

Most alarm systems will sound a loud wail or a siren to inform you about the presence of an intruder. However, at times, such sounds are at best avoided. Even though the receiver in most alarm systems is placed inside your home, you may not be the only person who may be able to hear the noise. Many states have tough regulations about noise pollution and burglar alarm systems. If it is a false alarm and your neighbor ends up calling the police, then you might end up being penalized for it. A voice alert system is a perfect alternative for a shrill sounding alarm. It consists of a PIR motion sensor device that alerts you about the intruder in a custom voice message recorded by you. You may record your own voice or the voice of someone close to you. 

How it works 

A voice alert system has a detectable range of up to 100 feet and consists of a PIR sensor that detects heat radiated by living things and movement as well. The sensor itself can be installed anywhere (including outdoors) without any sort of trouble or interference from rain and snow. As any sort of movement is detected in the protected zone, the PIR sends a radio signal back to the receiver which can be installed within your home (up to 1000 feet away). The radio signal can easily pass through walls and doors. However, metallic objects like aluminum grills or sliding panels may cause difficulties. Once the signal is received by the receiver, one of the following actions may occur. 

1. The custom recorded message will sound and inform you about the possible intrusion. Some models also mention the specific zone and location where the intrusion was detected.
2. You can then use the ‘C’ relay function within the system to either give the burglar a warning or alert the law enforcement agencies.
3. A normal voice alert system has different functions like volume control, message playback, custom message recorder, built in messages, missed message indicator that blinks if there are any messages that you missed while you were not present at home, a low battery indicator and the sensor indicator that indicates the life of any of your sensors.
4. Installing these systems is a cinch. All that you need to do is mount the PIR sensors in the places that you wish to, install the receiver at a precise place within your home and record different voice messages to identify each zone.
5. They can alert you accordingly when cars are coming up the driveway, children have ventured into your tool shed, kids are close to the swimming pool, there are possible intruders walking up the front or back door of your home, when someone enters your garage and when your parked vehicle or boat is boarded.  

Tips for buyers 

• You must always give careful consideration to the different features, quality and price of a voice alert system before choosing one.
• Some models have a limited monitoring capacity while other advanced models let you monitor up to 6 different zones at one time. Multiple beam patterns is another desirable feature.
• Some other features worth looking for are beam sensitivity, adjustable mounting and a delay timer.
• Always compare amongst the best models and select a model that suits your security requirements.
