Sony introduces infrared to its HD camera range

27 Jul 10

Fumi Kawamura, product marketing manager at Sony Video Security, said: “High quality image capture in extreme dark and pitch black environments has traditionally been a real challenge for the security industry.

“Now, thanks to the introduction of the embedded IR illuminator, Sony’s HD cameras enjoy clear visibility even under 0 lux, complete darkness. This is absolutely vital considering that many criminal infractions take place in limited light conditions.”

In addition to the infrared technology Sony has announced the launch of View DR, a camera feature which combines Sony’s full-capture Wide D technology, high-speed “Exmor” CMOS sensor and Visibility Enhancer, to facilitate HD image capture even in high contrast lighting environments.

Added functionality
Mike Cole, sales manager at Sony Video Security, said: “At Sony we work closely with our customers to add functionality that guarantees optimised images, even in unpredictable monitoring environments.

“In high contrast lighting conditions, such as a train station where a light source, such as the sun, is directly behind the subject, critical facial detail can be lost.

“However Sony cameras equipped with View DR have an extremely wide dynamic range, which resolves detail loss by adjusting the levels of chrominance and luminance. As a result monitored images can be seen with even greater clarity than the naked eye.”

Fully integrated
The full-capture Wide-D technology captures images using a ‘standard’ exposure time and takes either one or three images, depending on the camera type, using very short exposure time.

The newly developed View-DR algorithm nearly doubles the camera’s sensitivity, when compared to conventional Wide-D technologies, Sony says. To capture multiple HD resolution images at very high speed, the ‘Exmor’ CMOS sensor utilises its high-speed readout characteristics.

Sony’s SNC-DH180, vandal resistant IP Mini-dome camera and Sony’s SNC-CH180 outdoor network HD bullet camera are fully integrated with both infrared and ViewDR technology.
