Analog 480 TVL kit

This four-camera set uses wired BNC connections and requires a traditional analog DVR, monitor and cabling that are not included. It is designed for owners of legacy surveillance systems roughly ten years old who need direct replacements. New buyers without existing analog infrastructure should choose a different technology.

BNC wired constraints

The cameras transmit standard-definition NTSC video over coaxial cable to a compatible recorder. They cannot connect to HD, IP or wireless recorders and will not function as standalone units. Power is supplied through the included four-channel 12 V DC adapter using 2.1 mm centre-positive plugs.

480 TVL coverage limits

Each dome delivers 480 TV lines of horizontal resolution through a 3.6 mm wide-angle lens with a minimum illumination of 0.8 lux. The lens adjusts 90 degrees vertically and 360 degrees horizontally for flexible aiming. Detail and low-light performance are limited to the capabilities of the analog format.

Questions about this item

Should I choose this 4-pack or a single camera if I need to cover multiple angles?

The 4-pack provides four identical dome cameras and a 4-channel power supply, letting you wire up to four positions from one source.

What does 480 TV lines mean for the picture I will actually see on my DVR?

It is the horizontal resolution of the analog video signal; on a compatible DVR you will get a standard-definition NTSC image with 480 TV lines of detail.

The cameras use BNC video — what does that cap in practice?

BNC carries composite analog video only, so the signal is limited to 480 TV lines NTSC and cannot connect to HD or IP recorders.
