Wireless Vehicle Detecting Driveway Alarm with Loud Bell

The Protect 800 Wireless Vehicle Detecting Driveway Alarm is a premium driveway security solution, designed to detect moving steel only—making it ideal for properties with animals roaming freely. This system offers long-range wireless performance, an adjustable receiver, and a loud bell alert for maximum protection.

Kit Includes:

• 1 × Indoor 4-Channel Wireless Receiver with Plug-in Transformer

• 1 × Outdoor Wireless Transmitter & Vehicle Detecting Probe (14m Cable)

• 1 × Loud 85 dB Outdoor/Indoor Bell (3m Cable)

• 1 × Siren ON/OFF Cable Switch

• 1 × Set of Batteries

How It Works

• The hidden probe, buried just beneath grass or driveway surfaces, detects moving steel (vehicles) only—ignoring people and animals.

• Once activated, it transmits a wireless signal up to 800m line of sight (approx. 400–600m in most real-world applications) to the indoor receiver.

• The bell connects to the receiver with a 3m cable (extendable on request) and is controlled via the included ON/OFF switch.

• When the receiver is triggered, it chimes and activates the bell for a user-selectable duration: 5s, 30s, 60s, or 10 mins.

• Optional outdoor wireless receivers are available to connect bells, sirens, floodlights, or strobes—ideal when you don’t want to run additional cabling.
