Combining 5MP HD with a 155° Ultra-Wide Angle: An In-Depth Look at the Cost-Effective JSD2528 Lens
In the development of smart security, dashcams, and automotive vision systems (AVM), balancing high-definition resolution with a wide field of view and low distortion has always been a major pain point for hardware engineers.
Today, we take an in-depth look at the JSD2528, an industrial-grade lens that delivers both high resolving power and an ultra-wide field of view.
Core Specifications at a Glance
Before diving into the detailed analysis, let’s look at the hardware capabilities of the JSD2528 through its core technical indicators:
Parameter | Specification | Core Value |
Resolution | 5MP | Ensures fine image quality and captures more localized details. |
Image Format (Sensor Size) | 1/2.5" | Mainstream large sensor size; ample light intake, excellent low-light performance. |
Focal Length (EFL) | 2.65 mm | Typical short-focal ultra-wide-angle design. |
Aperture (F/NO max) | 2.8 | Balances depth of field and light throughput for sharp imaging. |
Field of View (FOV) | 155°(D) / 123°(H) / 91°(V) | Ultra-wide field of view to eliminate visual blind spots. |
Optical Structure (Element) | 6G (6 Full Glass Layers) | High light transmittance, heat resistant, built for harsh outdoor environments. |
Mount & Dimensions | M12*0.5P / TTL 22.8mm | Standard M12 mount, compact structure, easy to integrate. |
Three Core Competitive Advantages of the JSD2528
1. 5MP Resolution for Definitive Image Clarity
Compared to the common 2MP (1080P) lenses on the market, the JSD2528 supports up to 5MP resolution. Paired with a 1/2.5" large sensor size, the light-sensing area of each pixel is highly optimized. Whether in bright daylight or low-light night conditions, it delivers high-contrast, low-noise images—providing high-quality raw footage for backend AI algorithms (such as license plate and facial recognition).
2. 155° Ultra-Wide FOV, Perfect for Panoramic Applications
The JSD2528 features a 155° Diagonal Field of View (DFOV), meaning a single lens can cover an exceptionally wide area.
Optical Distortion Controlled at <-28.92%: For a 155° ultra-wide-angle lens, this level of distortion control is excellent. Combined with backend software de-warping algorithms, it easily achieves seamless, natural, and realistic panoramic imaging.
3. 6G Full-Glass Structure to Withstand Harsh Environments
The optical design utilizing 6 full-glass (6G) elements is the cornerstone of the JSD2528’s high stability. Compared to lenses containing plastic elements, full-glass lenses offer inherent advantages:
Zero Thermal Drift: In high-temperature automotive environments during summer or freezing outdoor security scenarios, the image will not defocus or blur due to temperature fluctuations.
High Transmittance: Effectively reduces ghosting and flare.
Recommended Applications
With its compact M12 standard mount and 22.8mm TTL (Total Track Length), the JSD2528 is ideally suited for integration into space-constrained devices:
Smart Automotive Vision: Dashcams, 360° Around View Monitoring (AVM) systems, and backup cameras.
Smart Security Monitoring: Panoramic IP cameras, video door phones, and drone aerial photography.
Industrial Vision Terminals: Robotic vacuum cleaners, AGV (Automated Guided Vehicle) visual navigation, and self-service kiosks.
The JSD2528 is a mature lens solution that balances a large sensor (1/2.5"), high resolution (5MP), and an ultra-wide angle (155°) within a compact form factor (M12). Its full-glass optical design ensures high stability and long-term reliability for mass production delivery.
If you are currently looking for a lens solution that delivers both image detail and a wide field of view, the JSD2528 is undoubtedly an ideal, cost-effective choice.
