COTINSE Wireless Motion Sensor LED Light with 500 ft Range

The COTINSE Wireless Motion Sensor LED Light is a plug-and-play motion detector and alarm system that pairs battery-powered sensors with a receiver to alert you up to 500 ft away.

This compact kit combines an infrared motion transmitter and a receiver chime with LED indication, offering audible and visual alerts when movement is detected. Designed for homes, shops, offices, and classrooms, the system is expandable, simple to install, and lets you choose from multiple ringtones and volume levels for discreet or attention-grabbing notifications.

How does the alarm notify me when motion is detected?

When the motion sensor detects activity it sends a wireless signal to the receiver, which flashes its LED and plays a selected ringtone. The receiver supports multiple volume settings so you can adjust the intensity to suit the environment.

• 58 ringtones to match different alert priorities
• 5 selectable volume levels for silent to loud notifications
• LED indicator flashes on each trigger for visual confirmation
• 110 dB maximum alarm output for high-traffic or noisy locations

What range and coverage can I expect from the transmitter and receiver?

The receiver and transmitter communicate wirelessly up to about 500 ft in open space, while the infrared sensor detects motion across a roughly 13–16.5 ft zone. The sensor gives approximately a 110-degree detection arc, suitable for doorways, hallways, and small entry areas.

• Up to 500 ft operating range between devices (line of sight)
• 13–16.5 ft motion detection distance per sensor
• About 110° detection angle for broad coverage at entrances
• Receiver accepts signals from multiple sensors for wide-area monitoring

Can I expand the system or pair multiple sensors?

Yes — the system is modular so you can add transmitters or additional receivers to match your security layout. Each receiver can pair with up to 20 motion sensors, letting you monitor multiple doors, aisles, or rooms with a single chime unit.

• Mix and match transmitters and receivers to create the right setup
• Each receiver supports up to 20 sensors for larger coverage
• Receivers plug into standard outlets; sensors run on AAA batteries (included)
• Simple pairing process for adding or replacing units

How easy is installation and everyday use?

Installation requires no wiring: mount the sensor where you need it and power it with the included AAA batteries, then plug the receiver into a wall outlet. Settings such as ringtone selection and volume are accessible on the receiver, making daily adjustments straightforward.

• Sensor mounts with included hardware; batteries are preinstalled
• Receiver plugs into any standard household outlet
• Quick setup and pairing—no electrician required
• LED flash provides immediate visual feedback when triggered
