CNB CCM-24VF 600TVL Box Camera

The CNB CCM-24VF is an analog CCTV box camera built for security installations that need true day/night monitoring. It uses a 1/3" high-sensitivity CCD sensor to deliver 600 TV lines of resolution in colour and 650 TV lines in black and white. The built-in vari-focal lens covers a 3.8-9.5mm range for adjustable field of view. Dual-voltage 12VDC/24VAC input simplifies power planning across sites.

Thermals, noise and power draw

The camera operates on 12VDC or 24VAC dual-voltage supply with no moving parts, so it runs silently in normal use. Intelligent IR technology drives two built-in SR LEDs for illumination up to 25m without hotspots. Minimum illumination reaches 0.005Lx in black-and-white mode, reducing the need for external lighting. The true day/night ICR filter switches automatically to maintain image quality across light changes.

Bundled accessories and software

The unit includes a built-in DC-iris vari-focal lens (f=3.8~9.5mm) so no separate lens purchase is required. On-screen display (OSD) menus give direct access to motion detection, privacy zone masking and mirror function settings. Digital noise reduction (DNR) and smart backlight compensation (SBLC) are configured through the same interface. RS-485 connectivity supports Pelco-D and CNB protocols for remote camera control from a DVR or keyboard.

Questions about this item

How do I connect the 12VDC/24VAC dual voltage and RS-485 interface during installation?

Wire the camera to either a 12 V DC or 24 V AC supply, then link the RS-485 bus using Pelco-D or CNB protocol for OSD control and PTZ commands.

Which parts of the CNB CCM-24VF will need replacement after extended outdoor use?

The two built-in SR LEDs rated for 25 m IR range and the mechanical IR-cut filter (ICR) are the items most likely to require service over time.

At what illumination level does the camera switch from colour to black-and-white mode?

The day/night transition occurs at 0.005 lx; below that threshold the ICR engages and resolution rises to 650 TV lines in monochrome.
