Messoa video surveillance solution secures Taiwan Life Insurance headquarters in Taiwan
Messoa video surveillance solution secures Taiwan Life Insurance headquarters in Taiwan

The new headquarters building of Taiwan Life Insurance, one of the top insurers in Taiwan, was complete in late 2012. Sit in the heart of the busy commercial district on Zhongshan North Road, Taipei City, the 12-storey, stone-facade building with the elegant interior design is a modern architecture engineered to meet the most stringent standards in engineering, green sustainability, and safety. Looking to house thousands of staff employees while integrating corporate resources all under one roof, Taiwan Life Insurance needed to employ a video surveillance solution that fulfills its highest requirements for securing the building’s overall safety. The insurer wanted both quality and reliability to ensure a safe and secure environment for everyone working and paying visits at the venue. Solution Several system integrators competed for the tender, and eventually Siemens came through based on the MESSOA video surveillance solution with the leading specifications and imaging performance. In early 2013, a total of just over 100 MESSOA CCTV cameras were deployed, covering the capacious 30,000sqm of gross floor space of the building. Among them, a dozen of SDS730PRO speed dome cameras were installed on the exterior of the building to secure the perimeters; thirty some pieces of SCR368 IR bullet cameras were mounted at security-concerning areas, overlooking the lobby, and key access points where adverse lighting is present; and the rest were SDR447 dome cameras, which were used for discreet monitoring of elevators, hallways, and staircases on each floor. Built in with Sony CCD and top-tier components, all three models deployed in this project deliver up to 700 TVL high quality images that are positive for identification and video analysis in case of any incidence. The camera sensitivity and image processing capability are further improved by the proprietary Lumii™ Technology to deliver sharper and crisper images under all lighting conditions at all times regardless of the locations the cameras are installed. Both the SDR447 and the SCR368 are fitted with varifocal lenses, which offer maximum flexibility in installation such that the security system can be easily adapted to various environments and be operated without any difficulty. The lean, compact size of SDR447 made the cameras discreet and unobtrusive, which goes rather well with the building’s classy interior design. Result The inspection team from Taiwan Life Insurance expressed their satisfaction after they had run a complete test on the system. They paid extra attention on the cameras’ performance, including the pan-tilt-zoom functions, as well as live view and playback video of all critical monitored scenes inside the building. Everything they saw on the monitor turned out clear, even where places that may be poor lit. The team was confident that the safety of its brand new headquarters can be well assured.

Bosch EX14 extreme environment camera enables effective monitoring of the Mount Erebus crater
Bosch EX14 extreme environment camera enables effective monitoring of the Mount Erebus crater

Mount Erebus is the ultimate proving ground The Bosch EX14 Extreme Environment Camera is an integral part of the permanent recording equipment at the edge of the Mount Erebus crater – Antarctica’s most active volcano. The camera is currently recording passive convention of the volcano’s lava lake and is ready to capture video of the next transition to explosive activity expected soon. Conditions on Mount Erebus are as extreme as they get – with winter temperatures below -67 degrees Fahrenheit, icy and stormy weather, and corrosive gases produced by volcanic activity. Problem: capturing volcanic activity in extreme conditions Surveillance equipment must survive extremely cold temperatures and corrosive gases Remote location means camera must operate reliably for long periods without human intervention Solution: EX14 withstands arctic blasts and volcanic gases Injection-moulded nylon construction is IP67, NEMA 6 and 6P rated to withstand corrosive and cold environments – from -76° F to +140° F (-60° C to +60° C) Insulated inner chamber eliminates the need for internal heaters and blowers High-resolution imaging – up to 540 TVL – enables effective monitoring Results: reliable operation for continuous observation Camera has captured video of volcanic activity from the rim of the Mount Erebus Crater for nearly five years without fail Withstanding temperatures below -67° F, icy and stormy weather, and corrosive gases, the camera is ready to catch the next transition to explosive activity

Bosch EX36 Corner-mount No-Grip Camera provides video surveillance at major Oregon and Washington hospitals

Hospital rooms must be well-lit for video surveillance to deliver usable images. At the same time, the rooms must be dark at night so patients can sleep. Surveillance equipment must also be designed for maximum durability and safety. To achieve effective surveillance video, major Oregon and Washington hospitals use the EX36 Corner-mount No-Grip Camera from the Bosch Extreme CCTV series in their Behavioural Health units, Sleep Research Labs and ER Holding Rooms. Problem: seeing in the dark Sleep researchers must observe patients while they sleep To avoid disturbing patients, visible lighting cannot be used Colour performance required during daytimes High resolution images required at all times Solution: Corner-mount Integrated day/night performance Integrated camera and infrared illumination for day and night 940nm infrared invisibly illuminates a room Patients can sleep undisturbed while doctors and researchers observe and monitor as if it were day Outstanding high resolution video in colour by day and in active-infrared monochrome by night Safe corner mount design, vandal resistant and impossible to grip Results: Safe, Effective Surveillance in Day or Dark Conditions Improved monitoring and observation techniques at hospital Decreased disturbance to patients Upgraded general surveillance Risk mitigation through enhanced safety for patients and staff
