CNB LMP-50S analog camera 700 TVL

The CNB LMP-50S is an analog CCTV camera built for 700 TV line resolution using a 1/3 inch CCD sensor. It suits installers who need a fixed 3.6mm lens and 12 infrared LEDs for night monitoring up to zero lux. The unit includes built-in audio capture and a mirror function for flexible mounting. Power input accepts 10 to 14 volts DC.

12 IR LEDs and built-in audio

Twelve IR LEDs provide illumination at 0.00 lux when active, while the integrated microphone adds sound to the video feed. Coaxial communication using Pelco-C allows remote camera control over the existing video cable. Auto gain control and automatic white balance adjust exposure and colour without user intervention. The fixed 3.6mm lens sets a constant field of view.

Check 12 VDC supply and coaxial cabling

Verify that your recorder or power supply delivers 10 to 14 volts DC to match the camera's input range. Ensure the site uses coaxial cable compatible with Pelco-C signalling for the communication features. The fixed 3.6mm lens cannot be changed, so confirm the viewing angle fits the scene. No varifocal adjustment or network interface is present.

Questions about this item

Will the 12 IR LEDs need replacement after long-term night use?

The camera uses 12 IR LEDs rated for 0.00 lux illumination; IR output gradually declines over years of continuous night operation, so plan for eventual LED module service.

What limits continuous recording first — the 1/3" CCD sensor heat or the 10-14vDC power range?

The 1/3" CCD and fixed 3.6mm lens run passively; sustained heat buildup in the sealed housing typically reaches thermal equilibrium before the 10-14vDC supply hits its limit.

How much fan noise or heat does the 12VDC supply generate during all-day operation?

The unit has no fan; it draws 12VDC silently, and the aluminium housing dissipates warmth from the CCD and 11 IR LEDs without audible noise.
