U21 Wireless Surveillance Camera with PIR Sensor and 1080P HD USB Portable Monitor

The U21 wireless surveillance camera offers a straightforward solution for keeping an eye on your property without complex wiring. Its low-power PIR human body sensor activates recording only when motion is detected, which helps conserve battery and storage. The camera is compact and connects via USB, making it simple to reposition as needed. With a 2.8mm lens and CMOS sensor, it delivers clear 1080P footage day and night.
Features and Construction

This camera combines essential monitoring features in a lightweight ABS plastic body. It is designed for ease of use and reliable performance in typical home environments.
Material and Build
The housing is made from ABS plastic, chosen for its practical durability and low weight. At only 30 grams, the camera can be placed on shelves, desks, or mounted discreetly without adding bulk. Its compact form factor makes it portable between rooms or locations.
Size and Practical Fit
The camera uses a 1/3-inch image sensor and a 2.8mm lens, providing a field of view suited to indoor surveillance. Its small size means it can be positioned in corners, on bookshelves, or near entry points without being obtrusive. The USB in-line design allows direct connection to a power source or compatible device.
Uses and Placement

Whether for home security or monitoring a small office, this camera adapts to various scenarios. Its motion-triggered recording and night vision make it useful for both daytime and low-light conditions.
Event or Professional Use
The camera works well for temporary event monitoring, such as checking a storage area or entrance during gatherings. The direct recording models (A through D) let you select a memory card option that matches how long you need footage saved. Models with 16G, 32G, or 64G cards record for 5, 10, or 20 days respectively.
Everyday Home Use
In a home setting, the camera can monitor a front door, hallway, or child's play area. The PIR sensor reduces false recordings from pets or passing cars, so you only capture relevant motion. The 16-metre effective detection range covers most standard rooms.
Benefits and Buying Value

This camera offers practical features without complicated setup. Its direct recording models simplify storage management, and the low-power design helps extend operational life between charges or plug-in usage.
Reuse and Low Maintenance
The camera's lightweight ABS build requires minimal upkeep. Simply ensure the lens is clean and the memory card has sufficient space. The PIR sensor and electronic shutter (1/3 second to 1/100,000 second) automate recording, so you do not need to manually start or stop it.
Why Choose This Product
If you need a straightforward, portable surveillance camera with night vision and motion detection, this model delivers the essentials. The combination of 1080P resolution, 16-metre detection, and direct recording makes it a practical choice for basic security needs.
