Product Description
Product Overview
TY-4008 is a professional 5-megapixel telephoto fixed lens designed for 1/2.5” image sensors, perfectly compatible with IMX335 and OV2710 sensors. With nominal 8mm focal length (actual EFL 7.6mm), this lens delivers narrow-angle long-distance monitoring with ultra-low TV distortion of only -2.2%, presenting natural, undistorted distant image details.
It adopts all-4-group full glass optical structure with fixed F2.0 constant aperture, stable relative illumination up to 68% and optimized chief ray angle below 17°. Compact overall dimension Φ14×14×20mm with standard M12×P0.5 thread mount, this telephoto lens is widely used for long-distance spot monitoring, license plate capture and outdoor targeted surveillance cameras. Custom processing service is available to support personalized hardware matching and mass production demands.
Core Features & Selling Points
1. 5MP High-Definition Long-Distance Imaging
Optimized for 1/2.5” IMX335 & OV2710 sensors, the lens supports 5MP high-resolution output. It clearly restores distant object textures, suitable for identifying distant targets such as vehicle plates and personnel features, meeting high-standard distant monitoring definition requirements.
2. Telephoto Narrow FOV for Targeted Long-Range Monitoring
Two sets of FOV parameters for different sensors:
- For IMX335: Diagonal 47.5°, Horizontal 38.5°, Vertical 29.5°
- For OV2710: Diagonal 48.5°, Horizontal 42.5°, Vertical 24.5°
The narrow telephoto viewing angle concentrates imaging range on specific distant areas, avoiding redundant wide-area frames and improving target detail recognition efficiency.
3. Ultra-Low TV Distortion (-2.2%)
Precision full-glass optical calibration controls TV distortion at merely -2.2%. The picture edge has almost no stretching or deformation, ensuring straight and natural outlines of distant targets, ideal for identification and recording scenarios requiring high geometric fidelity.
4. Premium 4G All-Glass Optical Structure
4 groups of full glass optical elements with multi-layer anti-reflection coating, featuring high light transmittance, stable optical performance and excellent anti-aging capability. Consistent clear imaging from center to edge during 24/7 continuous operation.
5. Fixed F2.0 Large Aperture & 68% High Relative Illumination
Fixed maximum & minimum F2.0 aperture ensures stable light intake for long-distance scenes. Relative illumination reaches 68%, effectively solving dark corners and uneven brightness at frame edges, keeping balanced brightness across the whole field of view.
6. Optimized CRA <17° for Perfect Sensor Matching
Chief Ray Angle strictly controlled below 17°, matching the light receiving characteristics of mainstream 1/2.5” CMOS sensors, reducing vignetting and edge light attenuation to maintain uniform full-frame clarity.
7. Mini Compact Body & Universal M12 Interface
Ultra-small overall size Φ14×14×20mm, lightweight and easy to embed into compact outdoor surveillance cameras. Standard M12×P0.5 thread mount is widely compatible with all M12 board cameras for fast installation and replacement.
Application Scenarios
1. Long-Distance Outdoor Target Surveillance
Perfect for parking lot license plate capture, campus road monitoring, factory perimeter monitoring and community remote road observation. The telephoto design clearly captures distant vehicle and human details without blurred frames.
2. Indoor Long-Range Fixed-Point Monitoring
Suitable for warehouse aisle long-distance observation, supermarket counter targeted monitoring and office long-corridor monitoring, focusing on specific distant key areas to reduce unnecessary monitoring blind spots.
3. High-Definition Recognition Camera Matching Lens
Matches intelligent license plate recognition cameras, access control long-distance identification modules and industrial remote visual detection equipment, relying on low distortion and high resolution to improve recognition accuracy.
4. Mass-Produced Outdoor Mini Surveillance Cameras
Standard supporting telephoto lens for batch production of 1/2.5” 5MP network board cameras, unified stable optical parameters guarantee consistent imaging quality of finished cameras.
