COTINSE Solar Motion Sensor Alarm with Strobe & Siren

The COTINSE Solar Motion Sensor Alarm is a battery-free outdoor security siren that combines a red-and-blue police-style strobe with two 130 dB speakers and 13 rotating alarm sounds to deter intruders day and night.

This weatherproof, solar-powered unit mounts outdoors to protect driveways, yards, barns and remote properties without wiring or frequent maintenance. A built-in PIR motion sensor triggers continuous-loop playback through dual speakers while alternating red and blue LEDs imitate emergency lighting, helping the device remain noticeable and unpredictable—two qualities that increase deterrence compared with single-tone alarms.

How does the rotating 13-sound system improve security?

The alarm cycles automatically among 13 different alerts—dog barks, sirens, animal calls and more—so potential intruders can’t habituate to one repeated tone. Rotating sounds maintain psychological uncertainty and increase the perceived risk for an intruder, making the deterrent more effective over the long term.

• Continuous loop playback while motion remains detected
• Includes dog barking, wolf howl, lion roar, gunshot and siren
• Prevents tone desensitization seen with single-sound alarms

What coverage and loudness can I expect outdoors?

Two independent 130 dB speakers produce stronger acoustic pressure and a broader sound field than a single speaker of the same rating. That wider dispersion helps the alarm carry across larger yards, farms and detached structures so neighbors and passersby can hear the alert earlier.

• Dual 130 dB channels for greater reach and clarity
• Better sound distribution for irregular outdoor spaces
• Speakers tuned for outdoor frequency ranges to cut through ambient noise

How do the LED strobe and operating modes adapt to different locations?

The unit’s alternating red and blue LEDs mimic police warning lights and remain visible in daylight and at night, increasing the alarm’s visual impact. Four selectable modes let you balance visibility and sound according to site needs—24/7 protection, light-only, night-only or night light-only—for flexible placement in residential, rural or quiet areas.

• Red & blue police-style strobe for high-visibility deterrence
• Mode 1: 24-hour sound + light; Mode 2: 24-hour light only
• Mode 3: night-only sound + light; Mode 4: night-only light only

Is installation and power maintenance difficult?

Installation is wireless and straightforward: mount the unit where the solar panel receives sun, set the desired mode, and the built-in solar array charges the internal battery. No mains power, external cabling or frequent battery swaps are required, making it ideal for remote properties or outbuildings.

• Top-mounted solar panel auto-charges daily
• Wire-free mounting for fences, walls and poles
• PIR sensor protects driveways, coops, orchards and ponds

Who is this for? The COTINSE Solar Motion Sensor Alarm suits homeowners, smallholdings and caretakers who need a low-maintenance, high-impact deterrent for outdoor spaces that lack easy power access. It’s designed for yards, villas, farms, barns and outbuildings where visual and audible presence deters intruders without professional installation. Choose this unit if you want a solar-powered, weather-resistant alarm with varied alarm tones, police-style strobe lighting and configurable modes to match different neighbourhood or site requirements.
