U21 Wireless Surveillance Camera with 1080P HD Resolution and PIR Motion Sensor for Indoor Home Security

The U21 wireless surveillance camera combines portability with practical security features in a compact ABS plastic housing. This indoor camera system delivers 1080P HD video through its 2 million pixel CMOS sensor, providing clear monitoring footage for home security applications. With dimensions of 1/3 inch and weighing just 0.03 units, this discreet camera can be positioned inconspicuously while offering a 16 metre effective monitoring range. The integrated low-power PIR human body sensor activates recording when motion is detected, conserving energy while ensuring relevant footage is captured. Operating on a 5V power supply with a working temperature range of -10°C to 60°C, this wireless camera offers flexible installation options for various indoor environments.

Features and Construction

The U21 camera's design focuses on combining essential surveillance capabilities with practical installation considerations for home use. Its wireless operation eliminates complex wiring requirements, while the portable monitor provides immediate viewing access to captured footage.

Material and Build

Constructed from ABS plastic, the camera housing provides structural integrity for indoor placement while maintaining the compact 1/3 inch form factor. This material choice supports the camera's lightweight design at 0.03 units, allowing for flexible positioning on various surfaces. The 2.8mm lens provides a standard viewing angle suitable for room monitoring applications, while the CMOS image sensor captures footage with 1920*1080 pixel resolution. The electronic shutter operates from 1/3 second to 1/100,000 second, accommodating different lighting conditions during recording.

Size and Practical Fit

With its 1/3 inch dimensions and minimal weight, this surveillance camera can be discreetly positioned in living spaces, entryways, or other indoor areas requiring monitoring. The compact form factor doesn't sacrifice functionality, as it incorporates a PIR sensor with 16 metre effective range and infrared lighting with 8 metre irradiation distance. This combination allows the camera to detect motion and provide night vision coverage within typical room dimensions. The 5V power requirement enables operation from standard USB power sources, further simplifying installation in existing home environments.

Uses and Placement

This wireless camera system addresses specific home security scenarios where discreet monitoring with clear footage is required. The portable monitor design provides immediate access to recorded content without requiring computer connectivity for basic viewing.

Event or Professional Use

For security monitoring applications, the camera's PIR motion sensor conserves recording storage by activating only when human presence is detected within its 16 metre range. The 1080P resolution ensures identifiable footage, while the 8 metre infrared capability provides night vision coverage for 24-hour monitoring situations. The signal-to-noise ratio exceeding 48db helps maintain image clarity, and the minimum illumination of 0.1 lux allows operation in very low light conditions before infrared activation. The -10°C to 60°C working temperature range supports installation in various indoor environments with temperature fluctuations.

Everyday Home Use

For typical residential security, the wireless design eliminates complex installation while the portable monitor allows immediate checking of camera footage. Homeowners can position the camera to monitor entryways, valuable possessions, or specific rooms requiring surveillance. The motion-activated recording through the PIR sensor reduces unnecessary footage while ensuring events of interest are captured. With options including models with integrated memory cards providing 5 to 20 days of storage (depending on card capacity), the system can maintain recorded footage for review without continuous computer connection.

Benefits and Buying Value

The U21 camera system offers specific advantages for users seeking straightforward wireless monitoring with essential features for home security applications.

Reuse and Low Maintenance

The ABS plastic construction supports durable indoor use with minimal maintenance requirements beyond occasional cleaning of the lens surface. The wireless operation reduces wear on connectors compared to wired systems that might experience connection issues from frequent movement or adjustment. With no moving mechanical parts in the camera housing, the design minimises points of potential failure, supporting continued operation across its specified temperature range.

Why Choose This Product

This surveillance camera provides a balanced combination of 1080P video quality, motion-activated recording, and compact wireless design suitable for discreet home monitoring. The inclusion of infrared night vision with 8 metre coverage extends functionality into low-light conditions, while the PIR sensor's 16 metre range accommodates typical room sizes. For users seeking a straightforward security camera without complex installation or ongoing subscription fees, this system offers the core features needed for basic indoor monitoring with the convenience of a portable viewing monitor.
