The new H.265 Wisenet XNB-H6461H Pinhole Height Strip camera from Hanwha Techwin (detail pictured) lets users covertly capture an image of a person’s face, and when used with another camera, establish the approximate height of the person. It’s aimed at banks, petrol stations, convenience stores and other retail applications.
The camera, which is able to support face recognition analytics, is designed to be installed at an exit door. Positioned at eye level and looking in, it is able to capture clear frontal images of faces which can be recorded and used as evidence to prosecute for theft or fraud.
Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe said: “Loss prevention managers have told us that it is not unusual for a thief to ‘case out’ a store before attempting to steal anything. 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.”
The 2 megapixel Wisenet XNB-H6461H pinhole camera comes with a 4.6mm fixed lens that provides a 73 degree field of view. It has Wide Dynamic Range (WDR), which performs at up to 120dB, to produce images from scenes containing a mix of bright and dark areas. This is quite often the case at entry-exits points of a building and normally results in over-exposed or under-exposed images. And built-in Highlight Compensation (HLC) solves the problem of over-exposure created by the presence of strong light sources, such as from store spotlights, the manufacturer adds.
The camera’s Hallway View provides a way to monitor narrow vertical areas such as shopping aisles and corridors. This enables the XNB-H6461H, which can generate images in the 9:16 and 3:4 aspect ratios, to work in tall and narrow spaces, with the bonus of minimising bandwidth and video storage. Other features include:
– 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 react to any incidents.
– A 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 per cent, it is claimed, compared to current H.264 technology when combined with H.265 compression.
– Power over Ethernet (PoE) which negates the need to install a power supply and separate cabling for the camera.
– A USB port which helps reduce the time installers have to spend on site by enabling them to remotely check via Wi-Fi the XNB-H6461H’s field of view and focus, from a mobile device.
