Features and Construction

This surveillance camera incorporates specific technical specifications that define its monitoring capabilities and operational parameters. The system balances image quality, detection range, and practical implementation through measured component selection and design choices.

Material and Build

Constructed from ABS plastic, the camera housing provides structural protection for internal electronic components against everyday environmental factors. This material choice contributes to the system's 0.03 unit weight and compact physical presence, allowing discreet placement in monitoring locations. The 1/3 inch size measurement indicates the camera's dimensional profile, supporting installation in constrained spaces where traditional surveillance equipment might prove impractical.

Size and Practical Fit

Measuring 1/3 inch in size with weight of 0.03 units, the camera maintains minimal physical presence while delivering 1080P resolution imagery through its 2.8mm lens configuration. This compact proportion facilitates placement in various monitoring scenarios without requiring extensive mounting hardware or significant spatial allocation. The system operates across -10°C to 60°C temperature ranges, accommodating installation in both interior and protected exterior locations within specified thermal limits.

Uses and Placement

The U21 camera system addresses surveillance requirements through specific technical capabilities that translate to practical monitoring applications. Its detection range, resolution quality, and included storage capacity provide measurable parameters for security planning and implementation.

Event or Professional Use

With 16 metre effective detection distance supported by passive infrared human sensing technology, this camera identifies movement across substantial areas for security monitoring applications. The 8 metre infrared illumination extends night vision capability, maintaining surveillance continuity through low-light conditions. Professional implementations benefit from the 1080P HD resolution providing 1920*1080 pixel imagery with horizontal resolution measured at 1080P TVL, delivering clear visual documentation suitable for identification purposes.

Everyday Home Use

Home security applications utilise the camera's compact ABS plastic construction weighing 0.03 units, allowing discreet placement in residential settings without intrusive visual presence. The included 16GB memory card stores approximately five days of continuous recordings, providing historical review capability without immediate data management requirements. Minimum illumination of 0.1 Lux combined with electronic shutter adjustment from 1/3 second to 1/100,000 second accommodates varying lighting conditions throughout daily cycles.

Benefits and Buying Value

This surveillance system delivers practical advantages through measured technical specifications and included components that address common monitoring requirements. The combination of detection capability, image quality, and storage capacity provides coherent functionality for security implementations.
