CCTV Lens – S04012808716ICR

S04012808716ICR is Wide-angle 8-Megapixel 1/2.8″ M12 CCTV lens With ICR holder, 104° diagonal FOV, F1.6 aperture, for security surveillance.

M12 4mm 8MP F1.6 Wide Angle CCTV Lens

This 4mm M12 wide angle CCTV lens is designed for 1/2.8″ 8MP sensors such as the Sony IMX415, delivering a 104° diagonal field of view with an F1.6 aperture. Its wide-angle coverage, strong light-gathering capability, and integrated ICR holder make it well suited for day/night security cameras and compact smart surveillance systems.

The combination of an 8MP optical format, 104° diagonal FOV, and F1.6 aperture makes this lens suitable for camera systems that require broad scene coverage while maintaining strong image brightness. For engineers matching the lens to a specific sensor, the Sensor Guide provides useful guidance on sensor and lens compatibility.

M12 4mm 8MP Wide Angle CCTV Lens Applications

Core Application Scenes

This 4mm M12 wide angle lens is optimized for surveillance systems that need to monitor a relatively large area from a fixed camera position. Its 104° diagonal field of view lets the camera cover a broad scene, so the lens targets indoor monitoring, entrance surveillance, corridor observation, retail environments and other locations with limited camera‑installation space.

The F1.6 aperture provides a useful balance between wide-area coverage and light-gathering capability. Against standard smaller‑aperture M12 lenses, this configuration serves security cameras better under variable lighting, such as dim indoor environments and nighttime scenes.

A key feature of this model is its ICR holder. The holder provides a mechanical interface for an IR-cut filter mechanism used in day/night camera architectures. During daytime operation, an IR-cut filter can be positioned in the optical path to maintain natural color reproduction, while the camera system can change its filter configuration for nighttime or IR-assisted imaging.

Because the lens has a relatively strong wide-angle distortion of less than -11.2%, it should be selected when scene coverage is more important than strict geometric accuracy. It is therefore better suited to surveillance and monitoring applications than precision measurement or low-distortion machine vision.

When designing a surveillance camera around a particular sensor and installation distance, engineers can use the FOV Calculator to estimate the expected coverage area.

Frequently Asked Questions

Q: What sensor is this 4mm M12 lens designed for?
A: The lens is designed for 1/2.8″ image sensors, with the specified field of view based on the Sony IMX415 sensor.

Q: What is the field of view of this 4mm M12 CCTV lens?
A: With the specified IMX415 sensor, the lens provides a 104° diagonal FOV, 87° horizontal FOV, and 46° vertical FOV.

Q: Is this an 8MP M12 lens?
A: Yes. The lens is designed for 8MP imaging applications using compatible 1/2.8″ sensors.

Q: What is the advantage of the F1.6 aperture?
A: The F1.6 aperture allows more light to reach the sensor than slower-aperture designs, making the lens suitable for surveillance systems operating under dim or changing lighting conditions.

Q: What is an ICR holder used for?
A: An ICR holder provides a mechanical interface for an IR-cut filter mechanism used in day/night camera systems. It allows the camera architecture to switch its optical filter configuration according to lighting conditions.

Q: Is this lens IR corrected?
A: The specification identifies an ICR holder, but this should not be interpreted as IR correction. An ICR holder is related to the camera’s IR-cut filter mechanism, while IR correction refers to the optical design’s ability to maintain focus across different wavelengths.

Q: Is this lens a low distortion lens?
A: No. Its specified TV distortion is below -11.2%, so it should not be classified as a low distortion lens. Its optical design prioritizes wide-area scene coverage for surveillance and monitoring applications.

Q: Is this M12 lens suitable for day/night CCTV cameras?
A: Yes. The combination of an F1.6 aperture, wide FOV, 8MP support, and ICR holder makes it particularly suitable for compact day/night security camera modules.
