Know when a car turns into your driveway, even from the far end of the house. The battery-powered sensor watches the driveway, and the receiver plugged in indoors alerts you with a tone and a light.

• Up to 1,000 ft of range: place the sensor at the end of a long driveway and still get the alert inside.
• No wiring outdoors: the weatherproof infrared sensor runs on a 9 V battery and covers a 40° zone.
• Tone and light alerts: the receiver sounds a tone at the volume you set and lights an LED, with a reset switch.
• Expandable: add more coded sensors to one receiver to also cover a garage, side gate or back door.
• Accessory jack: connect an extra sound or light indicator for a louder or more visible alert.
• Made in the USA: backed by a limited lifetime warranty.

Using it: mount the sensor where the driveway meets the road, aimed across the lane, and plug the receiver into an outlet in the kitchen or office.

What you need: a 9 V battery for the sensor and a standard 110 V outlet for the receiver.

In the box: infrared sensor/transmitter, plug-in receiver, mounting hardware and instructions.

Good to know: the sensor watches a 40° zone, so aim it across the path vehicles take rather than straight down the driveway.
