03 Aug Long range transmission forms heart of security solution for Durrat Al Bahrain islands
Bahrain-based systems integrator, Absolute Electronic Technology (AET), and Chinese security manufacturer Dahua, have provided a range of weather-resistant HD network cameras and long range video transmitters, as part of a customised security solution for the Durrat Al Bahrain luxury artificial island chain.
Durrat Al Bahrain is made up of 15 large luxury islands. Therefore, traditional wired or simple wireless transmission methods were not sufficient to support live video feeds over the large remote area. Instead, an innovative solution was required in order to ensure reliable long-range wireless video transmission throughout the area.
With numerous five-star hotels, a golf course, 12 bridges, and a marina, along with complex land and villa configurations on the crescent-shaped man-made islands, camera setups needed to be versatile, covering a large field of view to guarantee the safety of island tourists and workers while being discreet so as to preserve the luxurious nature of the island’s design. Cameras not only needed to support wireless transmission, but also withstand various outdoor conditions such as rain, storms, and relatively hot summer temperatures.
Dahua employed a comprehensive solution using 5.2GHz WLAN AP wireless HD camera products and a long-range 5.8GHz Wireless Video Transmission Device (PFM881). High-speed preview and playback digital video recorders (DVR) were also integrated into this solution, allowing workers to view live video feeds in up to 4K resolution, while supporting the recording of video onto high-capacity HDDs.
Multiple 5.8GHz Wireless Video Transmission Devices (PFM880/881) were installed, ensuring full live HD video transmission. The 3-5km range of the video transmission device ensures that live HD video feeds from the HD Network Cameras can be sent throughout the islands, thus cutting down on network infrastructure costs while resolving the issue of high-security coverage in remote areas. Other enhanced features include: the ability withstand outdoor temperatures of -30℃ to 70℃, a wireless transmission range of up to 5km and up to 300Mbps transmission speeds.
The main camera used in this project was the 2MP Full HD Network IR Bullet Camera (IPC-HFW2220R-Z). In order to protect against versatile weather conditions, namely rain and seawater, Dahua enclosed the connections for each HD network camera in its Waterproof Junction Box (PFA135). Key features of the 2MP Full HD Network IR Bullet Camera include: F1.4 aperture and infrared sensors with 30m range for optimal low-light / night recording, 25/30fps@1080P for high-quality video and a 30 – 98 degree angle of view.
32 Channel Super 4K Network Video Recorders (NVR608-32-4K) were installed to collect the various HD video feeds sent wirelessly from transmitters. Along with being able to record and playback 4K video, the recorders offer up to 32 channel IP camera input, 384Mbps incoming bandwidth, H.264H/H.264/MJPEG compression,8 SATA III ports, with support for up to 48TB of HDD storage andVGA/HDMI display output support.
As a result of this wireless solution, multiple types of cameras cover the island chain, which send feeds through long-range wireless transmitters to multiple HD DVR recorders. Because the recorders are more centralised and less devices and components are required in a wireless setup, the entire system was able to be implemented at a lower cost than other traditional configurations.
