SAFE-TECH Security is a leader in the industry of CCTV (Closed-Circuit Television). CCTV is the use of video cameras to record and view on a limited set of monitors the activity in a designated area. The signal is not openly transmitted, though it may employ point to point wireless links. CCTV is often used for surveillance in areas that may need monitoring such as homes, banks, casinos, restaurants, military installations and convenience stores to name a few. You can buy CCTV systems for personal, private or commercial use.
