Product Identity

The VideoSecu VD21WK4-N1 is a four-pack of wired analog dome cameras built for indoor and outdoor surveillance. Each unit uses a 1/3 inch CCD sensor with a 3.6 mm wide-angle lens and 20 infrared LEDs for night vision up to 0.0 lux. The cameras require a traditional analog DVR, coaxial cabling and a monitor to operate.

Interface Constraints

The cameras connect via BNC and draw DC 12 V from the four included power supplies. They output a maximum of 480 TV lines over standard composite video, so they cannot plug into HD or IP recorders. The analog signal limits resolution to standard-definition and does not support network streaming or wireless operation.

Upgrade Context

This kit replaces failed or missing cameras on an existing analog DVR system that is roughly 10 years old. It is not suitable for new installations, for anyone wanting HD or 4K recording, or for builders who need IP connectivity, wireless flexibility or standalone operation without a legacy recorder.

Questions about this item

Should I pick this 4-camera kit or a single-camera option?

This kit includes four identical dome cameras, four power supplies and a warning sticker, so one purchase covers four mounting points.

What does 480 TVL mean for the picture I will actually see?

480 TV lines is the maximum horizontal resolution the 1/3 inch CCD sensor delivers, producing standard-definition analogue video that a compatible DVR records.

The cameras use a BNC connection — what does that limit in practice?

BNC carries analogue composite video only, so the cameras must plug into an analogue DVR with BNC inputs; they cannot connect to IP networks, HD recorders or modern digital systems.
