Bluecctv BL-IR9043-G-4 480 TVL 42IR 4mm Grey analog camera

Bluecctv 480 TVL analogue camera

The Bluecctv BL-IR9043-G-4 is a 1/3" Sony Super HAD II CCD camera producing 480 TV lines of resolution. It delivers 512 by 492 effective pixels in a grey weatherproof housing. The fixed 4 mm lens suits general surveillance duties where a wide, fixed field of view is acceptable. Buyers needing varifocal adjustment or motorised zoom should look elsewhere.

42 IR LEDs give 60 feet night range

Forty-two infrared LEDs provide illumination to 60 feet, yielding a usable picture at 0 lux. Beyond that distance the IR output falls off and detail drops quickly. The fixed 4 mm focal length cannot be narrowed for longer reach, so the camera is not suited to corridors or perimeters requiring identification past the quoted range. Daytime colour reverts to monochrome when the IR array activates.

12 V DC 500 mA power requirement

The unit draws 500 mA at 12 V DC, so the supply and cabling must deliver that current reliably over the installed cable length. Voltage drop on long runs will cause instability or failed night operation when the LEDs switch on. Installers without a regulated 12 V source or adequate wire gauge should plan a different power topology before purchase.
