COTINSE Wireless Motion Sensor LED Light Door Chime

The COTINSE Wireless Motion Sensor LED Light is a plug-and-play door and motion alert system that combines a motion detector, LED indicator and chime receiver with a 500 ft wireless range for flexible home or business monitoring.

Compact and expandable, this kit pairs battery-powered motion transmitters with a plug-in receiver to give audible and visual alerts when movement is detected. Designed for quick setup, each sensor covers roughly 13–16.5 ft and a wide 110° detection arc; the receiver responds with one of 58 selectable ringtones and five volume levels. That makes it useful for monitoring doors, hallways, small storefronts, offices, classrooms and other indoor locations where you want an unobtrusive alert without hardwiring.

How does the system alert me when motion is detected?

When movement crosses a sensor’s infrared field, the transmitter sends a wireless signal to the receiver up to 500 ft away. The receiver flashes its LED indicator and plays the chosen ringtone at one of five volume settings, allowing both visual and audible notification.

• Receiver supports 58 ringtone options to suit environments.
• Five volume levels let you adapt alerts from discreet to loud (up to 110 dB).
• LED indicator provides a visible cue for noisy spaces.

Can I expand the system to cover multiple doors or rooms?

Yes — the COTINSE system is modular: each receiver can pair with multiple transmitters, and you can add extra receivers and sensors as needed. Mix and match quantities to create coverage tailored to your space.

• Each receiver can work with up to 20 motion sensors.
• Multiple receivers can be paired with the same sensor for wider alert distribution.
• No complex wiring — sensors use AAA batteries and receivers plug into standard outlets.

What are the installation and power requirements?

Installation is straightforward and requires no special tools: mount the motion sensor where it can view the area you want to monitor, insert two AAA batteries, and plug the receiver into a wall outlet. The sensor’s 110° field and 13–16.5 ft detection distance suit entrances and short corridors.

• Sensors mount with included hardware or adhesive and run on two AAA batteries (included).
• Receiver is powered by a standard AC outlet; LED flashes when receiving signals.
• Sensor coverage is ideal for doorways, vestibules and compact indoor spaces.

Will the system work in a store, office, or school setting?

The receiver’s choice of tones and adjustable volume make it adaptable to customer areas, back rooms, reception desks and classrooms. Since receivers can be placed where staff are present and sensors installed at strategic points, the system helps teams respond quickly to entries or movement without intrusive hardware.

• Selectable ringtones help differentiate alerts between zones or uses.
• Volume control prevents disruption in quiet environments while remaining loud enough for busy locations.
• Wireless range of up to 500 ft allows flexible placement of receiver and sensors across medium-size properties.

Who this is for: COTINSE’s Wireless Motion Sensor LED Light is aimed at homeowners, small business operators, shopkeepers and school administrators who want a low-cost, easy-to-install alert system without running wires or subscribing to monitoring services. It suits anyone needing quick visual and audible notice of doors opening or movement in defined indoor areas, and for users who want the option to grow coverage by adding additional sensors or receivers.
