Bluecctv BL-DO9881VF-IR-B-28 analog camera

This Bluecctv analog camera delivers 650 TV lines of resolution through a 1/3" Sony Super HAD II CCD with 811 x 508 effective pixels. A 2.8-12mm vari-focal lens allows the field of view to be adjusted during installation. Thirty-five infrared LEDs provide illumination up to 90 feet in complete darkness. The unit operates on 12V DC power and is housed in a black indoor-only casing.

Suited for fixed indoor surveillance needing

Installers who require a manually adjustable focal length for monitoring specific indoor zones will benefit from the vari-focal lens and 90-foot IR range. The camera is not suitable for outdoor deployment, as it is rated for indoor use only. Buyers who need network connectivity or Power over Ethernet must choose a different technology, since this model transmits analog video over coaxial cable.

12V DC analog power requirement

The camera draws power from a 12V DC source and outputs a standard analog video signal, so the installation must provide a compatible power supply and a DVR or monitor with a BNC input. No PoE or wireless transmission is included. Ensure the cabling infrastructure supports analog video before purchasing.

Questions about this item

What analogue video standard does the 650 TVL sensor output, and what practical resolution limit does that impose?

The camera delivers an analogue CVBS signal at 650 TV lines, which caps usable detail at roughly 650 horizontal lines regardless of the 811 x 508 effective pixel count.

What mounting clearance and cable entry does the indoor-only black housing require?

The indoor-only black case needs a flat surface with room for the 12 V DC power pigtail and the BNC video connector; no weather-sealed gland is provided.

How do I focus the 2.8–12 mm vari-focal lens during installation, and what step is commonly missed?

Power the camera, aim at the target area, then adjust the zoom and focus rings on the lens barrel until the 650 TVL image is sharp; the step often missed is re-checking focus after the IR LEDs switch on at night.
