In recent years, there has been increased emphasis on remote sensing
as an alternative to traditional systems that rely heavily on the deployment of extensive manpower for surveillance and security. Unattended sensors provide for continuous, widespread coverage and are more cost-effective than the deployment of personnel for many Homeland Defense and Law Enforcement applications. Such applications include international border security, perimeter defense of military installations, nuclear and other critical facilities, as well as detection of chemical or bio-terrorism attacks. Sensor technology has experienced significant advances in recent years. However, remote sensors still rely on batteries, which are short-lived and notoriously unreliable, thereby potentially compromising Homeland Security. There is a critical need for a long-term reliable energy source to power remote sensor networks. Such a battery-free alternative technology has been developed by Ambient Control Systems. Ambient has developed an advanced mid-door photovoltaic technology, which converts light to energy over a wide range of lighting conditions. The energy is then stored in supercapacitors, a highly robust, long-term storage medium. Ambient's advanced energy management technology can power remote sensor and control systems 24 hours/day, 7 days/week for over 20 years, without batteries and with virtually no maintenance, providing for ongoing monitoring and control.
