How a Proximity Switch Makes Your Car Safer
Nowadays, you can never be too careful when parking a car in a public place. Even if the vehicle itself does not pose as a ripe target, burglars can always pick the locks or simply smash the windows to get valuables and other things inside the automobile. Thus, how do you protect your car or the things inside it from being stolen?
Your best precaution, of course, is to buy a car alarm. However, you can make your anti-theft system even more efficient by incorporating a radar proximity motion switch, considered as one of the most effective intrusion sensors available. Using radio-frequency field-disturbance technology, it detects high density objects moving toward your car.
The great thing about this device is that it is designed to sense motion within an interior and exterior zone of protection, triggering a pre-warning output if it detects something. In other words, it acts as a double protective field around your car. You can also adjust its sensitivity according to your preference. If this sounds too technical, this scenario should let you understand how the proximity switch works.
Let us say an intruder wants to rob your car. As he comes within range of the exterior field generated by the vehicle's security system, the breach triggers your alarm to sound its pre-warning signal. If he comes closer and crosses the interior field, the main alarm is activated and will probably scare off the intruder. Even if your system lacks a pre-warning alarm, you can still use the proximity switch as a single-zone sensor. In addition, if you incorporate an automatic window roll-up kit, triggering the proximity switch causes the windows to automatically roll up. Now, installing this device in your automobile makes you feel safer, right?
