Alarm Sensors - What you need to knowIf you're looking for total peace of mind when it comes to your vehicle's security, you'll need a complete alarm solution that includes one or more alarm sensors depending on the type of vehicle and security requirement. Whilst a high quality, professionally installed immobiliser will stop an intruder from getting very far by shutting off the engine, alarm sensors are your best defence against any compromise of your cars security including any attempt to steal valuable contents from inside the cabin, such as laptops or power tools. Once triggered, an alarm sensor will immediately send a signal to your vehicle's siren - setting it off and sending the intruder running. Alarm sensors play such an important part in vehicle protection that they are a mandatory requirement for alarm solutions looking to meet the internationally recognised Thatcham alarm standard, such as the Autowatch 446RLi Premium and the Autowatch 695 CAN-BUS. Glass-break SensorA properly installed Glass-break sensor provides glass protection for all vehicles with hard-tops and windup windows. Built-in amplifiers filter and amplify the noises inside the cabin of vehicle. When the high frequencies associated with breaking glass are detected, a trigger signal is sent to the alarm system. Glass-break sensors are an extremely simple and effective security solution that are widely used. Wireless P.I.R SensorThese sensors work using Infra Red technology, much like the alarm sensors you see in many New Zealand homes. What's great about these sensors is that they don't require any cables, which makes them perfect for exposed areas such as ute canopies where a cable may be vulnerable to attack. Wireless Reed SwitchThese clever wee sensors are a good choice for doors, windows and canopies where threading cables just isn't practical. The Reed Switch mechanism senses when the vehicle's door, window or hatch is opened and triggers the alarm siren wirelessly. It's suitable for vehicles such as boats, trucks, motor homes, ute canopies or any vehicle with hatch-style doors or windows. Ultrasonic SensorUltrasonics work by triggering the alarm if a change in air pressure or movement is detected in the cabin of the vehicle. It monitors this by bouncing inaudible sound waves off the interior of the vehicles. These sensors are so effective that they are required for alarm systems looking to meet the internationally recognised Thatcham CAT 1 and CAT 2-1 standard. Because they detect air pressure owners must remember not to leave their windows open! Microwave SensorSimilar to an Ultrasonic sensor, Microwave sensors detect and protect against movement inside a vehicle cabin by establishing a microwave field which it then monitors. Microwave sensors are suitable for convertibles and targa tops as the microwave field is self-limiting, unlike Ultrasonic sensors which require a hard surface for reflection. Shock Sensor
A shock sensor is the simplest way to detect physical impact against a vehicle. The sensor's sensitivity can be adjusted depending on the size of the vehicle to avoid false alarms such as a the neighbour's cat jumping on the bonnet! Shock sensors will protect glass as any attempt to interfere with windows will exert vibration upon the vehicle.
Tilt SensorIf you've ever heard of tow-truck car thieves who literally steal cars by towing them away, you'll be pleased to know that you can protect your precious vehicle with a Tilt Sensor. These sensors have been developed to detect a change in the angle of the vehicle and impressively take into account strong gusts of wind by allowing time for the vehicle to return to the original angle (great for Wellingtonians!) |
