Dedicated Wisenet Pinhole Height Strip camera issued by Hanwha Techwin

The new H.265 Wisenet XNB-H6461H Pinhole Height Strip camera from Hanwha Techwin offers end users the opportunity to covertly capture an image of a person’s face and, when used in conjunction with another camera, establish the approximate height of the individual under surveillance.

Ideal for banks, petrol stations, convenience stores and other retail-type applications, the Wisenet IP network Pinhole Height Strip camera, which is able to support facial recognition analytics, is designed to be installed at an exit door. Positioned at eye level and looking in, it’s able to capture clear frontal images of faces which can be recorded and used as evidence in a bid to prosecute anyone arrested for theft or fraudulent activity.

“Loss prevention managers have told us that it’s not unusual for a thief to ‘case out’ a store before attempting to steal something,” said Uri Guterman, head of product and marketing for Hanwha Techwin Europe. “Having taken a close look at where the store’s video surveillance cameras are positioned, as well as the level of staffing, the thief then leaves the store only to return shortly afterwards with a cap or hat covering their face from the view of cameras which are normally installed on a ceiling looking down. The Pinhole Height Strip camera provides the opportunity to covertly capture a clear image of the culprit on their first visit to the store.”

Lens configuration

The 2 MP Wisenet XNB-H6461H camera is equipped with a 4.6 mm fixed lens that provides a 73° field of view. It also benefits from enhanced Wide Dynamic Range, which performs at up to 120 dB to produce clear images from scenes containing a challenging mix of bright and dark areas. This is quite often the case at entry/exits points of a building and normally results in overexposed or underexposed images.

In addition, built-in Highlight Compensation technology solves the problem of overexposure created by the presence of strong light sources, such as store spotlights.

The camera’s Hallway View provides a highly effective way in which to monitor narrow vertical areas such as shopping aisles and corridors. This enables the Wisenet XNB-H6461H, which can generate images in the 9:16 and 3:4 aspect ratios, to work effectively in tall and narrow spaces, with the added bonus of minimising bandwidth and video storage requirements.

Other key features

*Audio analysis which recognises critical sounds such as raised voices, screams, broken glass, gunshots and explosions, and generates an alert to enable security personnel to quickly react to any incidents

*Dual MicroSD/SDHC/SDXC memory slot which allows video or data to be stored at the edge

*Support for H.265, H.264 and MJPEG compression formats

*WiseStream II: a complementary compression technology which improves bandwidth efficiency by up to 99% when compared to current H.264 technology when combined with H.265 compression

*Power over Ethernet which negates the need to install a power supply and separate cabling for the camera

*USB port reduces the time installers have to spend on site by enabling them to remotely check (via Wi-Fi) the Wisenet XNB-H6461H’s field of view and focus from the convenience of a mobile device
