U21 Wireless Surveillance Camera with 1080P HD Resolution and USB Portable Monitor for Home Security

The U21 wireless surveillance camera system combines 1080P high-definition video capture with a convenient USB in-line portable monitor for direct viewing. This compact security solution features a low-power PIR (Passive Infrared) human body sensor that activates recording when movement is detected within its 16-metre range, making it suitable for monitoring entry points, rooms, or valuable items in residential settings. With infrared illumination extending up to 8 metres, the camera maintains visibility in darkness, while its ABS plastic construction houses the CMOS image sensor and 2.8mm lens within a lightweight 0.03kg body. Available configurations include direct recording models or units with integrated memory cards offering 5 to 20 days of continuous storage capacity.

Features and Construction

The U21 camera system incorporates several technical specifications designed for reliable home surveillance monitoring across varying conditions.

Material and Build

Constructed from ABS plastic, the camera housing provides durable protection for the internal components while maintaining a lightweight profile suitable for portable installation. The material choice contributes to the system's compact form factor and facilitates placement in various indoor locations. Within this housing operates a CMOS image sensor capable of capturing 2 million pixels, translating to the stated 1080P HD resolution that delivers clear surveillance footage with sufficient detail for identification purposes.

Size and Practical Fit

With dimensions measuring 1/3 inch, the camera unit maintains a discreet profile that can be positioned inconspicuously while providing its 16-metre detection coverage. The complete system includes a portable USB in-line monitor that allows direct viewing without requiring separate display equipment, enhancing its practicality for immediate monitoring situations. Weighing just 0.03kg, the camera can be mounted using minimal support structures and relocated as security needs change within the home environment.

Uses and Placement

This surveillance system addresses various home security scenarios through its combination of detection technology and viewing options.

Event or Professional Use

The camera's PIR sensor specifically detects human body movement rather than general motion, reducing false triggers from pets or environmental changes while ensuring recording activates when people enter its 16-metre range. This makes it suitable for monitoring specific zones like doorways, hallways, or valuable item storage areas where human presence requires documentation. The system's operating temperature range of -10℃ to 60℃ allows functionality in various indoor environments, from cooler basements to warmer attic spaces.

Everyday Home Use

For routine home security, the portable USB monitor provides immediate viewing capability without complex setup procedures. The infrared illumination extending to 8 metres ensures visibility in low-light conditions commonly encountered during evening hours or in poorly lit rooms. Available configurations with integrated memory cards (16G, 32G, or 64G) offer 5 to 20 days of continuous recording, providing sufficient historical footage for reviewing events while managing storage space practically.

Benefits and Buying Value

The U21 system delivers practical security monitoring through its integrated design and specification-focused performance.

Reuse and Low Maintenance

The wireless camera design eliminates cable management concerns while maintaining connection to its portable monitor, simplifying installation and potential relocation as monitoring needs evolve. With power supplied at 5V, the system operates efficiently, and its electronic shutter ranging from 1/3 second to 1/100,000 second adapts to varying lighting conditions automatically. The signal-to-noise ratio exceeding 48db contributes to clearer image quality by minimising interference in the captured footage.

Why Choose This Product

This surveillance system combines measurable technical specifications into a practical home security package. The 1080P HD resolution (1920*1080 pixels) provides sufficient detail for identification purposes, while the 2.8mm lens offers a field of view appropriate for monitoring defined areas. The minimum illumination of 0.1 Lux enables recording in very low light conditions before infrared illumination becomes necessary. These specifications work together to deliver a functional monitoring solution with defined performance parameters rather than ambiguous claims.
