U21 wireless surveillance camera with 1080P HD portable monitor and 16 metre PIR motion detection

The U21 wireless surveillance camera combines 1080P high-definition video capture with a portable USB in-line monitor for flexible home security applications. This compact system features a low-power PIR human body sensor that detects movement up to 16 metres away, automatically activating recording when motion is identified. The camera's infrared illumination extends visibility up to 8 metres in low-light conditions, while its small ABS plastic body allows for discreet placement in various indoor environments. With multiple recording configurations available, from direct recording to pre-loaded memory cards offering 5 to 20 days of storage, this system provides practical monitoring solutions for residential settings where clear footage and motion-activated recording are priorities.

Features and Construction

The U21 surveillance system incorporates several technical specifications designed for reliable monitoring performance. Its compact design integrates both camera and monitor functions into a portable unit that operates on standard 5V power, making installation straightforward without complex wiring requirements.

Material and Build

The camera housing is constructed from ABS plastic, providing a durable casing for the internal components while maintaining a lightweight profile suitable for various mounting positions. This material choice contributes to the camera's overall portability and allows for the small body design that enables discreet placement in home environments. The monitor component is integrated directly with the camera unit, eliminating separate power supplies and simplifying the setup process for users seeking straightforward surveillance solutions.

Size and Practical Fit

With dimensions measuring 1/3 inch, the compact size facilitates installation in limited spaces where larger surveillance equipment might be impractical. The portable monitor design connects via USB, allowing placement flexibility within the constraints of available power outlets and viewing requirements. The working temperature range of -10 to 60℃ ensures reliable operation in typical indoor environments, from cooler basement areas to warmer attic spaces, accommodating various residential installation scenarios without requiring specialised climate control.

Uses and Placement

The U21 camera system's technical specifications support multiple residential monitoring applications, from general home security to specific area surveillance. Its combination of motion detection, night visibility, and compact design makes it suitable for addressing various security concerns in domestic settings.

Event or Professional Use

For temporary monitoring needs such as property checks during holidays or event security, the portable USB design allows for quick installation without permanent modifications to the property. The 16 metre PIR sensor range provides coverage for medium-sized rooms or entryways, while the electronic shutter ranging from 1/3 second to 1/100,000 second captures both slow and fast movement effectively. The signal-to-noise ratio greater than 48db helps maintain image clarity even with background electrical interference that might occur in residential environments with multiple electronic devices.

Everyday Home Use

For ongoing home security, the multiple recording options accommodate different monitoring durations based on household needs. The 0.1 Lux minimum illumination enables the camera to capture usable footage in dimly lit areas like hallways or porches at night. The 2.8mm lens provides a field of view suitable for monitoring specific areas rather than wide spaces, making it appropriate for focused surveillance of entry points, valuable item locations, or rooms requiring occasional checking. The infrared illumination up to 8 metres extends monitoring capability through night-time hours without requiring additional lighting that might increase energy costs or draw attention to the surveillance system.

Benefits and Buying Value

The U21 system offers practical advantages through its integrated design and specification-matched components that work together for residential monitoring applications. These benefits focus on operational reliability and straightforward implementation rather than complex features requiring technical expertise.

Reuse and Low Maintenance

The USB-powered design allows for repositioning as monitoring needs change, supporting reuse in different locations without requiring new installation expertise or equipment. The CMOS image sensor and specified electronic components are selected to work within the stated temperature and power parameters, reducing likelihood of premature failure when used as directed. Available recording configurations let users select storage duration matching their review schedule, whether checking footage daily or weekly, with memory card options providing 5 to 20 days of continuous recording depending on selected capacity.

Why Choose This Product

This surveillance system addresses specific monitoring requirements through its combination of 1080P resolution, motion-activated recording, and compact portable design. The 2 million pixel sensor delivers sufficiently detailed footage for identifying individuals or activities within its 16 metre detection range. The integrated monitor eliminates additional display equipment, simplifying setup for users seeking straightforward security solutions without multiple components to connect and configure. The specified working parameters provide clear expectations for installation environments, helping users place the system where it can perform reliably according to its designed capabilities.
