This 18-channel CCTV power distribution box is built around a robust metal locking cabinet designed to house and protect the internal components in security installations. The enclosure is constructed from cold-rolled steel with a powder-coated finish, providing resistance against physical impact and environmental wear. The unit integrates a power transformer that converts AC110V input to a regulated DC12V output, delivering up to 40 amps of total current across 18 individually fused channels. Each channel is equipped with a resettable fuse or standard glass fuse holder, ensuring overcurrent protection per connected camera while allowing quick troubleshooting.

The internal wiring uses tinned copper leads and screw terminals for reliable low-resistance connections, minimizing voltage drop over long cable runs. A built-in cooling vent and adequate internal spacing support passive heat dissipation, contributing to stable long-term operation at full load. The power supply module employs a switching topology with overvoltage and short-circuit protection, maintaining output voltage within ±5% even under fluctuating AC input conditions. This design prioritizes consistent power delivery to cameras, recorders, and switching equipment, reducing the risk of image flickering or device dropout.

The front panel features individual LED indicators for each channel, providing immediate visual status of power flow. The locking cabinet includes a keyed latch to deter unauthorized access, making it suitable for public or semi-public areas such as retail stores, office buildings, and warehouse facilities. The unit comes with an integrated AC power cord and plug, simplifying installation without requiring separate wiring.

At a price of $80.00, this distribution box offers a cost-effective solution for centralizing power in mid-sized security camera systems. Its construction emphasizes functional durability rather than decorative finish, with all component ratings validated for continuous use under typical surveillance loads. The overall assembly complies with standard safety certifications for indoor use, and the terminal labeling follows clear numbering for easy channel mapping.

This power supply unit is intended for use with analog HD or IP cameras that demand stable 12V DC input, and it supports DVR/NVR systems that require consolidated power management. The 18-channel capacity aligns with common 16- or 18-camera setups, while the 40A rating allows headroom for peak current draw during initialization. Users should ensure proper grounding and avoid exceeding the maximum load per channel to maintain reliable performance.
