The new Wisenet PNM-9000QB camera module is designed for ATM, retail and other covert fraud and theft detection applications. Remote camera heads comprise an image sensor camera equipped 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 discreetly 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 powerful Wisenet7 chipset at its heart, the PNM-9000QB camera module is able to simultaneously process images from the 4 remote head cameras. With less cable and network switches required, this makes the module far more cost-effective than its single channel predecessor, as the time system integrators have to spend on-site is reduced. With just a single IP connection, there is also a cost saving for end-users, as only one VMS license is required.
When connected via specially designed cables and installed on the other side of a wall to a module, the camera heads are totally 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.
Additional protection comes in the form of 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 at the heart of the PNM-9000QB features Hanwha Techwin’s latest generation ‘extreme’ Wide Dynamic Range (WDR) technology. This performs at up to 120dB to enable each of the remote camera heads to capture clear, sharp 2-megapixel Full HD images at full frame rate even in strongly contrasting light conditions which often exist at ATMs’ sites.
With the support of WiseStream II, the bandwidth required to transmit images captured by a PNM-9000QB is significantly reduced, which may negate the need for banks to incur the cost of upgrading network capacity when the camera is retrofitted at an existing ATM location. This is because bandwidth efficiency is improved by up to 75% compared to current H.264 technology, when WiseStream II is combined with H.265 compression.
2 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 generation of Wisenet NVRs, facilitates the transfer and seamless storage of the images stored on the PNM-9000QB’s SD cards when the network connection is restored. This provides continuity of recording and negates the risk of what could be valuable video evidence being lost.
