COTINSE Wireless Motion Sensor LED Light — Motion Detector

The COTINSE Wireless Motion Sensor LED Light is a plug-and-play alert system that detects movement and sounds a customizable alarm up to 500 feet away.

Compact and expandable, this motion-detector alarm system pairs battery-powered sensors with a plug-in receiver to give you audible and visual alerts for doors, hallways, storefronts, or any indoor/outdoor transitional area. With 58 ringtone options, adjustable volume levels, and a wide wireless range, the kit is designed to be flexible for homes, small businesses, offices, schools, and rental properties.

How does the motion detection and alerting work?

The sensor uses passive infrared detection to spot body heat moving across its field and transmits a wireless signal to the receiver, which then plays a selected ringtone and flashes an LED. Detection covers roughly a 110-degree angle up to about 13–16.5 feet, so it’s best placed facing the expected path of entry or movement.

• Infrared sensing angle: approximately 110 degrees
• Detection distance: about 13–16.5 feet
• Receiver response: LED flash plus chosen ringtone
• Alarm volume: five adjustable levels up to 110 dB

Can I expand the system or customize alerts?

Yes — the COTINSE system is modular and meant to grow with your needs. Each receiver can pair with up to 20 transmitters, and you can mix and match multiple transmitters and receivers to cover different doors or zones. Choose from 58 ringtone options to assign distinct alerts to specific entrances or areas.

• Receivers pair with up to 20 motion sensors each
• 58 ringtone choices for unique alerts
• Five volume settings to suit different environments
• Mix-and-match transmitter/receiver configuration

What are the range and power requirements?

The wireless link between transmitter and receiver reaches as far as 500 feet in open space, giving reliable coverage across larger homes or small business layouts. Sensors run on two AAA batteries (included) for cordless placement, while the receiver plugs into a standard outlet so it’s always powered and ready to respond.

• Transmit/receive range: up to 500 feet (open area)
• Sensor power: two AAA batteries (included)
• Receiver power: plugs into standard AC outlet
• LED indicator on receiver for visual confirmation

How easy is installation and daily use?

Installation is straightforward: mount the sensor where it will see walkers or doors, insert batteries, and plug the receiver into an outlet. No wiring is required, and the system includes a visible LED indicator so you know when a signal is received. Ringtone and volume adjustments are handled directly on the receiver for quick tuning.

• No-wiring setup: mount sensor and plug receiver
• Includes batteries for immediate use
• Simple controls for ringtone and volume selection
• LED flash confirms each received alert

Who is this for? The COTINSE Wireless Motion Sensor LED Light is suited for homeowners, small business owners, shopkeepers, landlords, schools, and office managers who need a low-cost, easy-to-install alert system. It’s ideal where a visible and audible notice of movement is helpful — such as entryways, storage rooms, back doors, or seasonal displays — and for anyone who wants an expandable setup without complex wiring or recurring fees.
