5MP M12 Pinhole IR-CUT Dual Filter Switcher with 20mm Lens Mount

Upgrade your CCTV, IP, or HD camera system with this high-performance IR-CUT Dual Filter Switcher. Designed for 5-megapixel M12 pinhole lens setups, this compact module automatically switches between an IR Cut Filter (day mode) and a Fully Permeable Filter (night mode) — delivering sharp, true-to-life color images during daylight hours and enhanced brightness after dark.

Compatible with network cameras, HD security cameras, infrared cameras, and bullet-style cameras, this dual ICR switcher corrects daytime polarization issues and maximizes low-light performance at night. The electromagnetic switching mechanism is quiet, reliable, and retains its position even when power is removed.

How It Works

The IR-CUT Dual Filter Switcher uses a DC voltage circuit to control a magnetic rotary solenoid valve. When the red wire is connected to positive voltage, the module switches to the IR Cut Filter — ideal for daytime recording with accurate color reproduction. Reversing the polarity (black wire to positive) switches to the Fully Permeable Filter, maximizing sensitivity to infrared light for clearer night vision. Once switched, the mechanism holds its position without continuous power draw.

Frequently Asked Questions

Q: What cameras is this IR-CUT dual filter switcher compatible with?

A: This IR-CUT dual filter switcher is compatible with most M12 pinhole lens cameras, including network cameras, HD IP cameras, infrared security cameras, and bullet-style CCTV cameras. Its standard M12 20mm lens mount makes integration straightforward for a wide range of setups.

Q: How do I switch between day and night filter modes?

A: Switching is simple and controlled by DC voltage polarity. Connect the red wire to positive voltage and the black wire to negative to activate the IR Cut Filter (daytime mode). Reverse the connection to switch to the Fully Permeable Filter (nighttime mode). The filter holds its position even after power is removed, saving energy.

Q: What operating voltage does this dual ICR switcher require?

A: This switcher operates on a wide voltage range of 4–12V DC with a drive pulse signal time of 100ms, making it compatible with most standard camera power supplies and control boards.

Q: Does the filter retain its position when the power is off?

A: Yes. Thanks to its static energy retention design, the IR-CUT dual filter switcher holds its current filter position even when no power is applied. This reduces energy consumption and ensures stable performance between switching events.
