The DVR allows remote users to receive video clips and push video notifications triggered by motion detection Xvision, a Y3K company, has supplied an HD CCTV system to a busy London depot of DPD, a leading worldwide courier company. The installation, which will see the extensive depot upgrade its existing CCTV to 1080P resolution, is by Kent-based integrators, AVS Services, and includes hybrid IR vandal-resistant dome cameras and digital video recorders (DVRs). Logistics companies face many surveillance challenges at their distribution centers: notably harsh lighting conditions, abrupt changes in ambient light and dealing with the issue of capturing clear images while allowing for vehicle headlights and reflections. Crucially for this type of environment, the Xvision dome cameras can be adjusted for headlight compensation and number plate recognition at a distance of up to 12 metres. DPD wanted a CCTV solution with excellent low-light performance, high resolution and no latency; so they opted for Xvision’s full HD (1080P) vandal-resistant domes with wide dynamic range (WDR). The camera was specified to meet these needs and also to provide 40 metres of smart IR night vision. The camera’s versatility allows DPD to use the same model throughout the site, across packing areas, warehouse space, loading bays and administration offices. Minimizing Pixelation And Noise DPD is a 24/7 operation and managers needed a camera capable of switching automatically from color to monochrome using energy-efficient integrated infrared LEDs. The company’s chosen camera, the XHC1080VV-G professional hybrid IR vandal-resistant dome, has a SONY 2.43 megapixel sensor that provides exceptional image quality, day or night. The camera improves images in real-time through a DSP chip set that minimizes pixelation and noise in low-light conditions, producing a smooth image with an even spread of illumination. Dual HD1080P/960H Output Used by DPD at 1080P resolution, this is a dual output camera that can also produce images at 960H (960 x 480) in applications where image quality is important, but not at a premium – and where storage capacity may be limited. As the installers, AVS Services were working to a limited budget, but were able to save considerable installation costs by avoiding the use of RG-59 coax and designing the project to operate from existing Cat5e structured cable, with baluns used to preserve signal quality across long runs. This gives DPD a single infrastructure for CCTV and its IT system, all across one manageable network and without the need for additional cabling. Flexibility Offered By 16-channel Hybrid DVR The images at the depot are recorded on Xvision’s XHR1080D16 hybrid DVR, which can record sixteen 1080P cameras simultaneously at 15 FPS, full HD. In applications with a mixture of camera resolutions, the DVR can even sense alternative formats (such as 720P) automatically. Using P2P technology, the DVR connects seamlessly to the network with a free smartphone/tablet app that allows remote users to receive video clips and push video notifications triggered by motion detection. Raj Bhudia, Y3K’s Xvision Product Specialist, said: “AVS Services is a premium installer that came up with a practical solution at a demanding location. Using AHD2.0 analog cameras across existing twisted pair cabling reduced disruption at this busy logistics hub. The client can now use the same infrastructure for surveillance, data and telephony.” AVS Services specialises in CCTV, door entry systems and cloud computing across Greater London in the commercial, healthcare and domestic sectors. The company has particular strengths in the remote monitoring of CCTV and VoIP.
The HD IP IR CCTV system consisting of bullet cameras, domes and NVRs was set up to monitor the animals over a 2-month period Bristol Zoo has used Xvision’s IP infrared bullet and dome cameras to observe a range of mammals, birds and reptiles as part of a BBC documentary. Icon Films wanted to record animals in total darkness to study their nocturnal behavior and required high-quality night-time footage from equipment that would not disturb the creatures. The animals in the study included seals, lions, gorillas, monkeys and zebras. Naturalists were investigating to see whether animals dream, how marine mammals manage to sleep while in the water and why flamingos sleep with one eye open. An HD IP CCTV system consisting of bullet cameras, domes and Network Video Recorders (NVRs) was set up to monitor the animals over a 2-month period. Vandal-Resistant Domes Selected to Prevent Any Damage Xvision’s Pro HD CCTV range includes 4MP (2288 x 1712) H.265 compression vandal-resistant domes and mini-domes with up to 30 meters of smart infrared night vision that are ideal for this kind of project. The cameras were selected for their versatile optical performance and the effectiveness of the infrared LEDs. These cameras have Smart IR Technology built in that adjusts the intensity of the camera’s infrared LEDs to compensate for the distance of an object so that the infrared does not overexpose the object. Vandal-resistance in the strictest sense was not required, but a male zebra can weigh up to 300 kilograms so vandal domes in certain places were selected to prevent any damage. While making the program, the documentary company used an IP network to transmit images. Local storage is also an option with the Xvision range; 32 GB SD memory cards can be used at the edge as a primary recording device or for network back-up. Production Staff Able To View Multiple Feeds On NVR "The BBC has used further Xvision equipment for another major program involving animal studies and it’s rewarding to see surveillance technology meeting needs in areas that don’t involve crime for a change", said Raj Bhudia, Xvision’s Sales Manager The program-makers at Bristol Zoo, who also benefited from remote access using a smartphone app (iOS or Android), compared the sleep patterns and behavior of a range of animals in real-time across the course of a single night. Because the different animal pens and compounds at the zoo are spaced widely apart, a central studio was created from which the production staff could view multiple feeds on an NVR, which became the equivalent of a bank of monitors in a CCTV control room. Xvision’s 16-channel NVRs with built-in 16-port PoE switch were also used with some of the company’s own cameras for the zoo research as they were compatible with other major camera brands. When reviewing footage of subtle aspects of behavior among the smaller animals, the team was able to enjoy high levels of picture detail with these industry-leading NVRs, even when fully zoomed-in. Xvision NVRs can be triggered by motion if required and this proved useful at the zoo when an animal emerged from its burrow. Xvision products use the latest H.265 video codec, but even with this level of compression efficiency, recording on motion has major storage and bandwidth benefits. It also helped to alert filmmakers of any animal activity as it happened. Raj Bhudia, Xvision (a Y3K company) Sales Manager said: “The dispersed locations of the animals meant that the architecture of an IP installation was ideal for the documentary-makers as cameras could be easily moved and redeployed anywhere on the network. The BBC has used further Xvision equipment for another major program involving animal studies and it’s rewarding to see surveillance technology meeting needs in areas that don’t involve crime for a change.” Bristol Zoo is the world’s oldest provincial zoo. The mammal collection alone numbers over 300 animals from 50 species and keepers were among the first in the world to breed okapis (a giraffe-like species) in captivity. Bristol is also known for its thriving group of western lowland gorillas. Icon Films is a Bristol-based company which focuses on producing factual programs and documentaries and has particular strength in wildlife productions.
