Factory alarms vs aftermarket

Many of today's modern vehicles come supplied with a factory alarm from the manufacturer. But are they any good? Be in the know and check out our helpful article on factory alarms vs aftermarket.

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.


If 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.
