Video Marches Around the Perimeter 
By Bill Zalud
At the edge" camera decision-making, less expensive cameras, video motion detection, IP and wireless applications all come together to let security leaders implement security video as a perimeter protection solution. Although security video is used for many purposes, its most common application is for surveillance and alarm assessment. Systems make it possible for fewer individuals to maintain a constant watch, record and archive activities under surveillance, and provide a visual record that can be used to document activities for investigative use.
THE CHALLENGE
Video cameras comprise only one component of a perimeter protection system that includes smart fences, buried cable, lighting and other technologies. Following trends in other markets, the cost of cameras continues to fall while functionality increases due to the availability of more powerful and less expensive electronic components. As a result, low-cost, high performance cameras are widely available creating the opportunity for large scale exterior surveillance applications.
Security video systems configured with hundreds of cameras have become commonplace. IT network technology and low-cost hardwired and wireless IP networked video cameras, with embedded video compression technology, have taken hold to mitigate the escalating communications and electrical infrastructure and network administration costs.
Traditional CCD and CMOS video cameras require illumination, either from visible or from very near infrared light sources in order to produce a usable display picture. Reproducing a usable image becomes exceedingly difficult as illumination decreases, which creates the need for an exterior lighting source. Yet the cost of these systems is considerable and for many applications completely impractical such as borders, waterway areas, city-wide surveillance, power generation, refinery perimeters and airport applications. In other situations, lighting can either offend local residents or draw unwanted attention.

Washington Hospital Center Installs Defentect Radiation Detection Pilot as Part of Its Commitment to Advanced Emergency Preparedness
Defentect (OTCBB: SLNH) announced that it has been chosen by Washington Hospital Center to install a radiation detection pilot in strategic portal locations. Known for Project ER One and its commitment to advanced emergency preparedness, the hospital is home to large nuclear medicine and cancer treatment facilities. As a medical community frontrunner, the Hospital Center is preparing for the unthinkable, but very real possibility of a radiological event in the nation's capital. Defentect's solution will monitor for the ingress of radiologically contaminated patients as well as the illicit egress of on-premise radiological materials used to treat patients.
Can better detection provide a better response?
Behavioral screening -- the future of airport security? Keep your shoes and belts on: Waiting in long airport security lines to pass through metal detectors may soon be a thing of the past. Security experts say focus is shifting from analyzing the content of carry-ons to analyzing the content of passengers' intentions and emotions. "We are seeing a needed paradigm shift when it comes to security," says Omer Laviv, CEO of ATHENA GS3, an Israeli-based security company.

Terrorism and New Biometrics Technologies
Implementing biometrics-based technologies has increased in recent years and is helping to protect the nation and multi-national enterprises by keeping people and assets more secure. New, lightweight, multimodal devices help make distinguishing between an insurgent and a civilian in a war environment easier.
