Home Alarms Systems

Ultra-Sonic Home Alarms Systems

Sound frequency in the ultra-sonic range is inaudible to the human ear. Such ultra-sonic frequencies when applied in burglar alarms provide a lot of protection for your assets, property, family and yourself. This is why ultra-sonic alarms are also known as ‘silent’ alarms. It is not at all difficult to install the ultra-sonic burglar alarms. Such a system coupled with a 24 hours monitoring ensures quick response in case of a break-in.

You might wonder about the working of the system if it is a ‘silent’ alarm. That is justified as you cannot hear the alarm at all if it goes off. This is also the reason why many people decide against ultra-sonic burglar alarms. However, it is more likely for a burglar to be caught in the act if you have an ultra-sonic alarm system installed. This is owing to the fact that the thief cannot hear the alarm ringing.

Working
The ultra-sonic alarm system makes use of sound waves in the house which act as motion sensors. They are projected in the form of beams which get dispersed by a coverage lens. The angle of dispersion depends on the lens configuration. Whenever there is a change in the vibration of sound, the dispersion also changes and the alarm sets off. They also detect changes in surrounding temperature.

Points to consider:

Lens position
While it is true that the governing factor here is the coverage lens, you must also remember the position of the lens. It should be placed at a proper angle. There are chances of the alarm being set off by the mere change in the direction of the sunlight. To avoid such false alarms, the lens must be positioned accordingly.

Pets
Position of the beams must be such that your pet does not trip accidentally setting off the alarm. To avoid this, position the beams such that it does not set off a false alarm.

Animals can hear ultra-sonic sound. Therefore, once the silent alarm is set off by an intruder, your pet will start barking as the alarm sound is an unusual occurrence for your pet. Thus, while your pets risk a false alarm to be set, they are the ones to warn you of an intruder.

Price
The cost of ultra-sonic alarm systems vary. However, the entire cost can be often waived off if you hire a security company for monitoring long term. Some companies offer incentives like additional keypads or window alarms while buying an ultra-sonic alarm system. There are also do-it-yourself kits available in the market. However, it is recommended that installation of ultra-sonic beams be done by professionals. This is because they are experienced in lens positioning. They position your lens such that the beams point in the right direction considering all factors like lifestyle, pets etc. Sensitivity level is also set accordingly.
