The TECKNET indoor motion sensor alarm is a wireless infrared security detector designed to provide audible alerts for unauthorized movement in various indoor environments. It features a loud 125dB siren that activates upon detection, combined with a remote control operating at a range of up to 328 feet, allowing users to arm, disarm, or trigger the alarm from a distance. The built-in PIR sensor covers a detection angle with a range of 40 feet, making it suitable for monitoring entry points in homes, garages, vans, or storage areas.

Constructed with a durable ABS plastic housing, the unit is compact and lightweight, enabling simple placement on shelves, walls, or desktops. It operates on three AA batteries (included), ensuring cord-free installation without the need for wiring or outlets. The passive infrared technology responds to changes in heat signatures emitted by humans and animals, minimizing false triggers from small pets when properly positioned.

An adjustable sensitivity setting further refines detection for specific room layouts. The alarm system includes both a chime mode and an alarm mode. In chime mode, a gentle tone sounds when motion is detected, useful for alerting to entry without causing disruption.

In alarm mode, the 125dB siren blasts for a preset duration before automatically resetting, deterring potential intruders. The remote control features a panic button for manual activation, and the alarm unit also has a built-in tamper switch that triggers if the device is moved or removed from its mounting surface. This motion detector is powered by a low-power consumption design, allowing extended battery life under normal use.

The straightforward setup process involves inserting batteries, selecting the desired mode, and mounting the sensor at the recommended height for optimal coverage. Its versatility makes it appropriate for residential spaces, office areas, workshops, or temporary security needs in vehicles. The combination of loud siren, long-range remote, and reliable PIR detection provides a practical, cost-effective addition to a layered security approach.
