Homeland Security has become a top priority for law enforcement and federal government agencies, and surveillance plays an important role. Suspects are monitored using unattended, hidden camera equipment or listening devices that require a reliable, quiet, uninterrupted power supply. The duration of these missions is mostly limited by the batteries and other power sources used. In certain cases, battery replacement is not an option as visits to a surveillance site may compromise an operation. The power needed for surveillance applications ranges from 15 Watts to 75 Watts, which typically includes a recorder, a video camera and potentially a transmitter. Typical surveillance applications include:

• Directional microphones

• Subminiature cameras

• Closed-circuit video monitoring

• Global Positioning System (GPS) tracking

• Radio Frequency Identification Device (RFID) tagging

• Command and Control Training Vehicle (CCTV) images

• Military reconnaissance

• Unmanned Aerial Vehicle (UAV)

• Internet and computer surveillance

The use of UltraCell XX25™ fuel cells allows unattended operation of these remote monitoring devices over longer periods of time and ensures reliability even in harsh environments.
