Profile: Detection Systems & Engineering Co. specializes in detection systems. Our product line includes digital & IP video surveillance, card access control, burglar alarm, counter surveillance, and intercom systems. Our intrusion alarm, or burglar alarm, is generally the first line of defense against a break-in, or other unauthorized entry to a facility. The intrusion alarms range from the very basic siren system to the complex internet based system. Our bug detection devices include radio spectrum analysis, telephone line analysis, and numerous other tests using various types of specialized equipment. When an inspection is performed at a site, all possible types of radio signals are searched and demodulated. The telephone and office equipment are also thoroughly inspected for any modifications that could be used for eavesdropping. The telephone lines within the premises as well as those extending out to the phone company central office can be inspected and analyzed. Finally the telephone equipment closets and connecting blocks are examined, completing the general sweep. We provide different methods of security services.
