Hanwha Techwin launches two new AI-powered dual-channel multi-sensor cameras designed to monitor two different areas with two different fields of view, making them ideal for monitoring staircases or escalators, L-shape corridors, and securing two adjacent areas such as check-in desks.
The two-in-one cameras feature highly accurate deep-learning-based object detection and classification while representing a lower total cost of ownership (TCO) over installing two equivalent cameras. Not only do they offer the advantage of lower hardware costs, but they are also faster to install, use one cable and in most cases require only a single VMS licence. The PNM-C12083RVD comes with two 6MP cameras at 15fps, while the PNM-C7083RVD has two 2MP at 30fps. Both come with an IR (infrared) viewable length of 25m, are NDAA compliant, and feature next-level cybersecurity with TPM 2.0 and are FIPS 140-2 certified.
AI-based object detection reduces the occurrence of false alarms, providing operators with a reliable source of events, while accurate object classification improves operational efficiency by making forensic search highly efficient. The cameras can detect human faces, as well as identify particular vehicles and number plates while ignoring irrelevant motion such as wind-blown trees, shadows, stray objects, or animals moving within the field of view.
Quickly review events
For post-event analysis, the dual-channel cameras utilise BestShot technology to support operators in quickly seeing the best shot of an event occurring. Camera-generated metadata (person, face, vehicle, and licence plate), is embedded in the video and delivered back to a control room, so a compatible VMS can carry out a highly efficient forensic search.
Enhanced image quality
AI also enhances the image quality of video delivered back to operators. WiseNR II noise reduction uses AI to identify object movement and reduce blur in noisy, low-light environments. AI-based Preferred Shutter technology automatically adjusts shutter speed based on classified objects in motion and the lighting conditions, to reduce motion blur and deliver the clearest images possible.
WiseStream III dynamically controls encoding so that when a classified object is detected, the compression rate on the area is minimised to improve image quality, while the rest of the scene is compressed at a higher rate. Combined with H.265 compression the bandwidth efficiency can be improved by up to 75% compared to current H.264 technology.
Excellence in product design
Hanwha Techwin’s reputation for excellent product design has been reflected in the aesthetics and durability of the cameras. The cameras are robust and hard-wearing in any weather with IP66, IK10 and NEMA4X certifications. They also feature a metal-shielded RJ-45 to protect the cameras from transient voltage, a hard-coated dome bubble providing better resistance to scratching and a GORE vent to prevent condensation and maintain performance. Furthermore, the installation has been made easy with CVBS video output and a Wi-Fi dongle USB port for viewing and adjusting cameras from a smartphone.
