Camera module

by Mark Rowe

The new Wisenet PNM-9000QB camera module is designed for ATM, retail and other covert fraud and theft detection applications, say the manufacturers Hanwha Techwin.

Remote camera heads comprise an image sensor camera with a fixed, pinhole or fisheye lens. As their name implies, they are designed to be installed remotely from the other components of a video surveillance camera and this means they can be discretely installed within an ATM and other tight spaces, or located neatly into a corner of a room or lift with the help of mounting brackets.

With Hanwha Techwin’s Wisenet7 chipset, the PNM-9000QB camera module is able to simultaneously process images from the four remote head cameras. With less cable and network switches required, this makes the module more cost-effective than its single channel predecessor, the company says, as the time system integrators have to spend on-site is reduced. With a single IP connection, there is also a cost saving for end-users, as only one video management software (VMS) licence is required. Installed the other side of a wall to a module, the camera heads are isolated from the network. Although this is likely to be of benefit to most end-users, it will be of particular importance to banks who need to protect confidential customer data and prevent fraud.

More protection comes with tamper detection which generates an alarm if someone covers, changes the angle or sprays paint on one of the head camera’s lens. The Tamper Detection feature is included in the module’s suite of Intelligent Video Analytics (IVA), as is defocus detection, motion detection and loitering detection.

The Wisenet7 chipset in the PNM-9000QB features Hanwha Techwin’s latest ‘extreme’ Wide Dynamic Range (WDR). This performs at up to 120dB to enable each of the remote camera heads to capture 2-megapixel Full HD images at full frame rate even in contrasting light conditions as often seen at ATMs’ sites.

With the support of WiseStream II, the bandwidth required to transmit images captured by a PNM-9000QB is reduced, the product firm says, which may negate the need for banks to incur the cost of upgrading network capacity when the camera is retro-fitted at an ATM location. This is because bandwidth efficiency is improved by up to 75 per cent it is claimed compared to H.264 compression, when WiseStream II is combined with H.265.

Two Micro SD/SDHC/SDXC slots enable up to 512GB of video or data to be stored at the edge should communication between the PNM-9000QB and a Wisenet NVR be disrupted. The Automatic Recovery Back-up (ARB) feature built into the latest Wisenet NVRs, aids the transfer and storage of the images stored on the PNM-9000QB’s SD cards when the network connection is restored. This provides continuity of recording.

Other features include:

– Hallway View enables operators to monitor tall and narrow spaces such as shopping aisles;
– Support for H.265, H.264 and MJPEG compression formats;
– two alarm input/outputs (I/O);
– HDMI output; and
– Power over Ethernet (PoE+) which negates the need to install a power supply and separate cabling for the camera.

The UL Cybersecurity Assurance Program (UL CAP) certificated Wisenet7 chipset built into the PNM-9000QB is packed with technologies which collectively offer the highest possible levels of protection for edge-based cameras from the activities of cyber criminals. These cyber security technologies, together with tamper detection and the use of special network cables, offer banks, retailers and other types of end-users with peace of mind in knowing their confidential data will be kept safe from hackers.

The PNM-9000QB has also been developed to meet the UK’s Secure by Default standard and as such, is cyber and network secure by default out-of-the-box, the makers add.

Uri Guterman, Head of Product and Marketing for Hanwha Techwin Europe said: “The PNM-9000QB camera module offers a highly secure and cost-effective way for security personnel to monitor live images or capture video evidence of activity at rows of ATMs installed at airports, banks, hotels, leisure facilities or shopping centres. With criminals finding ever more sophisticated ways to commit fraud at ATMs, the module offers an affordable and flexible way to covertly monitor any suspicious activity and use the captured video to carry out post-incident forensic investigations.”
