4K video cameras feature latest lens and image sensor technologies

Sony’s imaging division now offers further additions to its FCB video camera offering. The new EV9500 Series comprises three different models, each based on its 4.17M pixel 1/1.8-type STARVISTM CMOS image sensors. The EV9500H offers an HDMI output, while the EV9500M and EV9500L have MIPI and LVDS interfaces, respectively. All three of these camera blocks provide a 30x enhanced optical zoom and a 12x digital zoom – with no image deterioration being encountered when these functions are employed.

The STARVIS CMOS sensor integrated into the Series camera blocks has an anti-reflective coating that alleviates ghost effects and ensures that images are captured correctly (with no risk of vital information being missed). Its elevated spectral sensitivity performance in NIR/IR frequencies indicates that these cameras are highly optimised for surveillance deployments.

The proprietary cell structure and circuit technology used in the series design allows much higher sensitivity levels than those attained by conventional cameras – with a 50dB image signal to noise (S/N) ratio being displayed. This means that these units are especially ideal for use in low light environments. They also provide next-generation image stabiliser technology, which points to increased blur suppression when exposed to heavy vibrational forces. The Noise Reduction (NR) function eliminates random and non-random noise from the obtained images. At the same time, low focal plane distortion capabilities resist the image warp that would normally occur when dealing with swiftly moving subjects.

With compact dimensions of just 56mm x 64mm x 125 mm, the series camera blocks can be included in space-constrained application settings. Among their key applications are security systems, shipboard imaging equipment, drones, automotive imaging systems, automated guided vehicles and industrial monitoring infrastructure.

They may be powered by a 7VDC to 12VDC source - with the EV9500H drawing 6.3W, the EV9500M 6.8W and the EV9500L 7.8W when their motors are in operation. A working temperature range of -5C to +60C is supported, with an internal temperature measurement sensor included providing ongoing monitoring.
