Description
Introduction
- This 5MP M8 mount wide angle fixed focal lens is engineered for compact miniature security monitoring and mini machine vision equipment, equipped with 5-group glass + IR cut optical construction to deliver consistent day-night clear imaging across 1/2.5-inch image sensors.
- Featuring 165° diagonal ultra-wide field of view and compact TTL14 body size, this miniature fixed iris lens solves limited installation space pain points of small IoT cameras, smart home devices and miniature industrial vision modules, widely adopted in global consumer smart security and miniature industrial inspection fields.
- Strictly optimized per industrial optical standards, the lens balances ultra-wide viewing coverage and controllable distortion, serving as a mainstream alternative to oversized M12 lenses for space-restricted embedded camera development.
Key Product Highlights
Field of View & Focal Length Advantages
Delivers 165°D/123°H/91°V ultra-wide FOV with fixed 3.6mm focal length, eliminates blind monitoring spots without needing multiple assembled lenses, cutting client’s extra hardware procurement cost.
Core Imaging Performance
5Megapixel high resolution matching standard 1/2.5” sensor +<25% controlled distortion + integrated IR cut filter, realizes sharp daytime color imaging and clear night infrared monitoring, avoids color cast common on non-IR-corrected cheap wide-angle lenses.
Installation & Structural Compatibility
Standard M8×0.35 miniature thread mount and short 14mm total track length, perfectly fits ultra-narrow inner cavity of mini camera housings; manual fixed focus with 0.2m MOD enables close-range object capture without auxiliary focusing accessories.
Cost-Effective Quality Assurance
All-glass 5G optical structure with fixed F2.4 large aperture ensures stable light intake under low-light environment, RoHS & ISO9001 certified production reduces after-sales failure rate compared with plastic lens alternatives.

Product Application Scenarios and Compatible Devices
Core Application Scenarios
Primarily used in mini smart doorbell cameras, small indoor battery-powered IoT security cameras, miniature automotive blind-spot auxiliary monitoring, compact automated industrial component inspection, tiny robot onboard vision modules and portable wearable recording cameras. Especially designed for equipment with extremely limited internal lens installation cavity, its ultra-wide 165° FOV covers full surrounding monitoring range with single-lens setup, removing extra multi-lens layout cost and structure modification work for device developers. The fixed F2.4 aperture guarantees steady imaging performance in dim indoor, semi-outdoor and enclosed industrial workshop lighting environments, well adapting to variable ambient light changes of smart home and miniature industrial application scenes.
Compatible Devices List
Compatible with mainstream 1/2.5-inch CMOS image sensors, partially adaptive to matched-size 1/3-inch compact sensor modules; fits Tuya-enabled mini IoT camera mainboards, multiple brands of smart video doorbell core modules, small-sized aftermarket vehicle auxiliary camera assemblies and custom miniature machine vision inspection circuit boards. Custom focal length and FOV modification service is available to satisfy personalized hardware adaptation requirements from OEM device manufacturers and security solution developers.
Designed for miniature wide-angle CCTV & embedded machine vision application.
FAQs
Q1: Is this M8 lens compatible with M12 mount camera modules?
A: No, it adopts exclusive M8×0.35 thread mount; customized adapter ring can be developed if cross-mount conversion is needed.
Q2: Does the built-in IR cut filter support day-night switchable infrared imaging?
A: Fixed integrated IR cut design filters infrared ray under normal use; IR-pass customized version can be ordered for full-night infrared-only monitoring.
Q3: Can the focal length and FOV of this 3.6mm lens be adjusted?
A: It is fixed focal fixed zoom lens, focal length and FOV are fixed; custom optical design is available for alternative focal parameters.
Q4: What is the minimum working distance for object shooting?
A: Minimum object distance is 0.2m, ideal for close-range small object inspection and short-distance indoor scene monitoring.
Q5: Is third-party product performance testing acceptable?
A: Yes, the lens supports third-party lab testing and complies with EU RoHS & ISO9001 standard specifications.
