In the ever-evolving landscape of security technology, the P-Iris (Precise Iris) lens series stands out as a revolutionary advancement, akin to the James Bond of iris technology. Developed by Computar, P-Iris lenses bring a new level of precision and automation to iris control, significantly enhancing image quality in critical applications such as airports, government buildings, and banks. This article delves into the workings of P-Iris technology, its applications, and the myriad benefits it offers in the realm of high-end security cameras.

Understanding P-Iris Technology

The "P" in P-Iris stands for "Precise," a fitting descriptor for the advanced iris control mechanism embedded in these lenses. Unlike traditional lenses, P-Iris lenses leverage a sophisticated interplay of hardware and software to automatically determine and set the optimal iris opening size. This results in clearer and more precise images, making it an ideal choice for security cameras in environments where accuracy is paramount.

How P-Iris Works

At the core of P-Iris technology is an automatic and precise iris control mechanism. The DC auto-iris lens adjusts the iris based on lighting conditions, but P-Iris takes this a step further. The digital iris control allows seamless communication between the camera's software and the lens, enabling the system to set the F-Stop at the optimal position for the best image quality. Additionally, the P-Iris camera software adjusts gain based on the F-Stop, eliminating the need for a neutral density filter and maintaining optimal iris position for extended periods.

Selecting the Best Mode with P-Iris

P-Iris technology offers flexibility by allowing users to choose between two modes: Best Quality and Best Depth of Field.

Best Quality
In this mode, the P-Iris camera optimally adjusts exposure based on lighting conditions. In low-light situations, the iris fully opens to capture more light, while in bright conditions, the iris closes to a position that avoids diffraction or blurring. This dynamic adjustment not only enhances overall picture quality and sharpness but also minimizes resolution differences between the center and corners of the image, ensuring consistent clarity.

Best Depth of Field
Depth of field is a critical factor in achieving optimized image quality, especially in scenes with varying foreground and background resolutions. P-Iris technology helps in maintaining a good depth of field by optimizing the available depth, resulting in sharper images throughout the scene. This is particularly useful in scenarios like long corridors, where foreground and background resolution are crucial.

Enhanced Image Quality and Durability

P-Iris lenses offer more than just precise iris control; they are designed for superior image quality and durability. The lenses optimize resolution not only at the center but also at the corners of the image, ensuring consistent sharpness. This feature is particularly advantageous in applications where uniform image quality is essential, such as surveillance in large open areas.

Moreover, P-Iris lenses are built to withstand harsh environmental conditions. They are resistant to dust and moisture, making them ideal for outdoor security cameras that operate in extreme weather. The lenses are also designed to resist vandalism damage, adding an extra layer of reliability for security systems deployed in public spaces.

Versatility and Compatibility

One of the standout features of P-Iris lenses is their compatibility with a wide range of camera models and brands. This versatility makes them an attractive option for security system integrators who need a reliable and high-performance solution that can seamlessly integrate with various setups. The ability to enhance the capabilities of existing camera systems makes P-Iris lenses a smart investment for organizations looking to upgrade their security infrastructure.


In conclusion, P-Iris technology represents a significant leap forward in the realm of iris-controlled lenses. Its automatic and precise iris control mechanism, coupled with the ability to select between Best Quality and Best Depth of Field modes, ensures optimal image quality in diverse lighting conditions. The durability of P-Iris lenses, combined with their compatibility with a wide range of cameras, makes them a versatile and reliable choice for security applications.

As organizations continue to prioritize security in critical environments, investing in P-Iris lenses becomes not just a technological upgrade but a strategic decision to enhance the overall effectiveness of surveillance systems. With the P-Iris lens series, the future of high-end security cameras is clearer, sharper, and more precise than ever before.
