The product is a passage detector with integrated motion sensor and alarm function, manufactured under the brand NONAME. It is designed for monitoring rooms or passageways and triggers an audible alarm upon detection of motion. The device is intended for use in buildings where a simple, battery-operated security solution without complex installation is required. The functionality is based on a passive infrared (PIR) sensor that detects motion in the surrounding area and subsequently activates a siren.

Motion detection and alarm function
The detector captures motion within a range of up to 5 meters. The detection angle is approximately 140°, providing sufficient coverage for areas such as corridors, entry zones, or small rooms. Upon detection of motion, a siren with a sound level of 85 decibels is activated. The alarm duration is approximately 6 to 8 seconds, after which the device automatically turns off. This duration is sufficient to attract attention without being excessively disruptive.

Operation and power supply
The operating voltage depends on the number and type of batteries used, with the typical voltage for three AA batteries being 4.5 volts.

Mounting and installation
The detector features a flexible wall and ceiling mount, enabling easy installation on various surfaces. Installation can be performed without additional tools or drilling, provided the mounting options of the holder system are sufficient. The device dimensions are 100 mm height, 65 mm width, and 38 mm depth, making it compact and unobtrusive. Installation is typically performed at a height that optimizes the detection range, such as in the middle of a wall or on the ceiling.

Applications
The passage detector is suitable for use in apartments, commercial spaces, warehouses, or other indoor environments where simple motion detection with an audible warning is sufficient. It is not intended for outdoor use, as no protection rating such as IP67 or equivalent is specified. The functionality is designed for detecting persons or moving objects indoors.

Technology explained simply
The sensor operates on the principle of a passive infrared (PIR) sensor, which detects thermal radiation from moving objects. The siren generates an audible alarm tone, which is typically perceptible in the immediate vicinity due to its 85 dB sound level. The combination of motion detection and audible warning serves to deter or notify in case of unauthorized access.

Compatibility and accessories
The device is designed as a standalone system and requires no additional components for operation. The use of accessories such as additional sensors or remote controls is not intended and not described.

Advantages in operation
The detector offers a simple, low-maintenance solution for room monitoring. Installation is quick and does not require electrical wiring. Operational reliability is based on the dependability of the PIR sensor and the audible alarm function. The 85 dB sound level ensures sufficient audibility indoors. The flexible mounting allows adaptation to various rooms and installation situations.
