Alarm system expansions

Extensions for alarm systems make your home even more secure. For example, you choose motion detectors, sirens, or window sensors. With a motion detector, you ensure that nobody enters your house unnoticed. The sensor quickly notices someone and ensures that the alarm system gives you a signal. With a siren, you ensure that the alarm sounds loud and clear that there is an unwanted burglar in your house. A window sensor gives a signal when a window is opened when you're not at home or when a window is left open when you are away. Make sure that the extension is suitable for your alarm system. This way, you can be sure that you can link the products.
