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
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

Bosch Extreme series bullet cameras capture high-quality images for public prosecution
Bosch Extreme series bullet cameras capture high-quality images for public prosecution

Bosch WZ20 bullet cameras capture high-quality images suitable for prosecution under poor lighting conditions Problem: delivering prosecutable evidence under challenging lighting conditions There has been a high volume of criminal activity around the perimeter of developments and in elevators operated by New York City Municipalities. It has not been easy in the New York Area, explains David Gonzalez, Director of Business Development for Tri-Ed / Northern Video Distribution: “Low to no lighting around the perimeters makes them prime targets for criminals at night. NYC Agencies & Authorities have been concerned with security issues in elevator cabs as well, since cameras were easily and quickly vandalised in such environments. The NYC Agencies & Authorities were looking to install a cutting-edge surveillance system that would operate well under poor lighting conditions and in vandal prone areas to help them successfully prosecute criminal offenders.” Solution: corner-mount no-grip and bullet cameras The Bosch Extreme series Corner-mount No-grip and Bullet Cameras are precision engineered to deliver video suitable for prosecution in tough environments and under poor lighting conditions. The EX36 cameras’ steel construction protects against even the most brutal attempts to destroy, detach or disable the camera WZ20 bullet cameras deliver 150ft (45m) of high-performance night vision in 0 lux environments Results: cameras are an indispensable duo for criminal prosecutions David Gonzalez discovered that the WZ20 Bullet Cameras reliably captured high-quality images suitable for prosecution under poor lighting conditions, while the Bosch Corner-mount No-grip Cameras were highly resistant to vandalism. “The Agencies & Authorities are now able to work with police departments and district attorneys to successfully prosecute criminal activities at their buildings and developments.”
