Small and medium-sized businesses and homeowners now want to see—clearly—what’s going on around them 24x7. They need your expertise to build an intelligent solution to help traditional security and surveillance systems watch over multiple locations simultaneously using remote cameras and centrally located monitors.

A common problem among network surveillance systems is the ability of the camera to capture detail in dark or obscured lighting situations, such as garages or stairwells. That is starting to change, as Sweden-based camera manufacturer Axis Communications announced it is bringing its Forensic Wide Dynamic Range technology to several of its network cameras.

The new technology enhances the ability of the camera to capture detail in difficult and variable light conditions. Surveillance operators will be better able to see forensic details in challenging lighting conditions, such as doorways or interior spaces with windows that have bright areas juxtaposed with extremely dark.

Capturing Details in the Darkness

Axis Communications Forensic WDR is an enhanced Wide Dynamic Range (WDR) method of video capture that focuses on achieving “high forensic value,” according to the company. WDR is a term that is commonly used for the balancing of very dark and very bright areas in a fixed scene. Also called High Dynamic Range (HDR) in the surveillance industry, the aim of the new technology is to capture forensic details at all times, as the light changes with movement.

“Until now, the WDR methods on the market have not been able to add sufficient forensic value to ultra-high resolution cameras or surveillance scenes that feature a significant amount of movement,” said Ryan Zatolokin, Senior Technologist, Axis Communications, Inc., in a statement.

Axis Communications will add Forensic WDR to six of its network cameras in the AXIS P32 and AXIS Q35 lines. The AXIS P32 models are available through Axis’ standard distribution channels at a retail price ranging between $779 and $1,099, depending on the model. The new AXIS Q35 cameras will range from $1,099 to $1,249 and will be available in the third quarter of 2017.

As WDR video technology improves, the demand for DSS is starting to boom, with major growth in the areas of digital network equipment. IT convergence in the video surveillance industry is also happening, along with a strong rise in the market for edge-based analytics. Overall, the video surveillance market is expected to grow at a compound annual growth rate of 25.2 percent globally in the next several years, according to forecasts from Axis Research Mind.

Goodbye, Decoy Cameras

The importance of having reliable surveillance camera technology was reinforced by a situation in the San Francisco Bay Area. Until this month, the BART trains for commuters had a combination of working cameras and decoys with blinking lights, which administrators said were installed only to deter vandals. In 2016, a criminal incident occurred on a train that resulted in a passenger’s death. Because that train only had a decoy camera, BART police had no video evidence, and the crime remains unsolved.

The transit district rectified the situation in late June, giving the BART system a $1.42 million surveillance system upgrade. It replaced all its decoy cameras with working digital surveillance technology. The new video systems on the trains include four digital cameras on each car and DVRs with housing units, costing $463,749, according to the San Francisco Chronicle.

BART uses a robust network of high-end security cameras on its platforms and inside stations that are monitored by security administrators in real time. While the video footage on the moving trains will not be instantly accessible, police can retrieve it from the digital recorder (when needed) on each train car.
