Digital surveillance system is able to perform everything that a conventional surveillance can perform. In addition, digital surveillance system brings together the applications of broadband network and the conveniences of video digitization. The five major advantages of digital system are listed below:

  1. Superior Quality. The main concern with storing video footages on traditional video cassette is whether it can be kept in a good condition for a duration of time. Usually video quality becomes diminished or distorted due to the humid environment and attrition. However, digital surveillance system is not affected by this problem since it stores high resolution video in digital format.
  2. Time saving. Replacing video tapes every day is an extremely time consuming procedure. Digital Surveillance System supports repeated recording, so no replacements of storage device is necessary.
  3. Manpower saving. Traditional Surveillance System require a technician to maintain and manage its tapes. Digital Surveillance System is not the same. When a video needs to be watched all you have to do is start the video file stored on your system, no rewinding or searching for the right tape is required.
  4. Space saving. Bulky traditional tapes can take up quiet a bit of storage space. With digital system's superior recording time and repeated recording function, no extra space for tape storage is required.
  5. Lower cost. Traditional surveillance system operates on the base of machinery gears wheels, and belt which easily damages the system's components such as tapes and magnetic heads. Digital Surveillance System costs you no consumables parts.
  6. Superior storage capacity. 120GB hard discs at DVR you see on the market can usually support up to 8~10 days of recording. It is even longer for PC system.
  7. Easy management. Digital system's file management system saves you time from searching for tapes.
  8. Easy Installation. Insert the card into the PC before the software installation. Wires are not required for connecting quads and VCR. An all in one DVR is even simpler.
  9. Automatic repeated recording. Tape replacements are no longer required in digital systems. You won't have to miss out important events because you forgot to renew your tape again.
  10. No location limitation. "Remote Access" function allows you to monitor the activities in your factories from the other side of the world.

Digital Surveillance System VS Traditional Surveillance System
