business news Dahua meets complex wireless surveillance challenge Bahrain dahua Technology has provided and applied innovative wireless solutions to achieve extensive surveillance coverage for the Durrat Al Bahrain luxury artificial island chain. Durrat Al Bahrain features a total of 15 large islands that hold an 18-hole golf course, marina, restaurants and shops, and over 1000 villas in a 21 square kilometre area. As the area became more popular and drew increasing numbers of tourists, the resort owner needed a high-security surveillance solution that would cover all main areas, including points of access and the holiday villas. Dahua and local system integrator, Absolute Electronic Technology solved this complex surveillance issue for the island chain by providing a number of weather-resistant HD network cameras and video transmitters, as well as high-speed, HD DVRs as part of this customised solution. An important condition while implementing this solution was that since Durrat Al Bahrain is an island chain, traditional wired or simple wireless transmission methods would not suffice 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. Cameras not only needed to support wireless transmission, but also withstand various outdoor conditions such as rain, storms, and relatively hot summer temperatures. In order to supply highquality, wireless video feeds over the entire resort, Dahua employed a comprehensive solution entailing the use of 5.2GHz WLAN AP wireless HD camera products and the versatile, 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 highcapacity 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. The main camera used in this project was the 2MP full HD network IR bullet camera (IPCHFW2220R-Z). Its enhanced wireless transmission abilities and high-quality image ensure complete coverage. 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). 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 also supports 32-channel IP camera inputs, 384Mbps incoming bandwidth, SATA III ports (for up to 48TB), and VGA/ HDMI display outputs. The wireless network infrastructure used in this solution has significantly improved the efficiency in placing surveillance around the islands. Project manager Ian Bessly gave his feedback on the results of this project, stating: “Thanks to Dahua advanced wireless transmission solution and all kinds of HD dome and fixed cameras, which completely solve the challenge of network infrastructure shortage and meet the requirement from our customer.” Remarkable ROI for UK logistics company Copenhagen, Denmark Milestone Systems has collaborated with Oncam and Aspro Security to deliver an almost immediate return on investment and providing a cost effective security solution to one of the UK’s leading logistics companies. The solution combines Milestone Xprotect Professional software and BCD video storage with Oncam 360° cameras that provide comprehensive coverage of the site, resulting in full situational awareness. The previous video management system at the international logistics and supply-chain company could no longer provide all the coverage and information needed for their UK site. Specialising in surface transportation, freight brokerage, warehousing and distribution, ample coverage and image clarity were vital for verifying compensation claims and for reinforcing health and safety policies. Independent security consultant Aspro Security redesigned the site’s video monitoring system, incorporating Milestone Xprotect Professional software with Oncam’s 360° camera technology. “The ROI of the upgraded video monitoring system has been remarkable,” says Aspro’s Technical Manager, Nick Sergeant. “Within the first three months, the site saved approximately 65,000 US dollars in false and erroneous claims, which paid for the upgra- ded system almost twice over.” Video monitoring has not only helped the company with saving money but also prevented incidents and injuries to maintain an excellent safety culture. Extremely detailed footage retrieved from Oncam 360° cameras has been incorporated into safety training at the site to help communicate health and safety policies, as well procedural guidelines, more effectively. As a result, staff have gained a better understanding of how they make the working environment safer for everyone. The new system has improved adherence to safety policies and guidelines and saved approximately $65,000 in the first three months of the installation.
