Four-camera analog kit

This VideoSecu BC27BK4-N1 pack supplies four bullet cameras built around a Sony CCD colour DSP that delivers 480 TV lines of horizontal resolution. The fixed 3.6 mm wide-angle lenses give a broad field of view for general surveillance. All four units draw 12 V DC at 500 mA each and ship with a single four-channel power supply and mounting brackets. The kit is intended for installers extending or repairing an existing analog DVR system.

Weatherproof housings run cool and silent

Each camera’s aluminium body is rated for indoor and outdoor use without fans or moving parts, so operation is completely silent and heat dissipation is passive. The 12 V DC input keeps wiring simple and power draw predictable across the four channels. No network circuitry means no background traffic or firmware overhead to affect reliability. The included power supply handles all four cameras from one outlet.

Plugs straight into a legacy DVR

The cameras output composite video over BNC connectors and require a traditional analog DVR, coaxial cabling and a monitor — none of which are included. They will not work with modern HD, IP or wireless recorders, and they cannot operate as standalone devices. The 3.6 mm fixed focal length cannot be adjusted after mounting, so installers needing varifocal lenses or remote zoom should look elsewhere. The NTSC signal format matches North American legacy systems.

Questions about this item

How do I install the four cameras and where is the wiring mistake people make?

Mount each bullet camera with its swivel bracket, run a BNC video cable from every camera to the DVR, and connect all four cameras to the included 4CH power supply; the common error is plugging a camera into a separate 12 V adapter instead of the supplied multi‑channel unit.

What maintenance or replacement will the cameras need later?

The Sony CCD sensor and 3.6 mm lens are sealed inside the weatherproof aluminium housing, so no routine cleaning or part replacement is required; only the 12 V DC 500 mA power supply may need swapping if it fails after extended use.

What limit appears first when the cameras run continuously outdoors?

Continuous exposure to sun, rain and temperature cycles will degrade the weatherproof seals before the 480 TVL image sensor or the fixed 3.6 mm lens shows any performance loss.
