Advantages Of Using Fiber Optics In Security And Surveillance Systems
Fiber Optic Security System
Nowadays, fiber cable are widely used and gradually replaced the copper cable in the video security & surveillance systems. With the benefits of fiber cabling, many limitations are solved. The benefits of fiber cabling as the following:
Allows for extended transmission distances
- Multimode cable < 2km (1.24 miles)
- Single mode cable > 2km
Smaller size, less weight and better tensile strength
- Easier installation when pulling through conduit or overhead cable trays
Usually existing as network backbone in vertical risers and between buildings
- Reduce cost by utilizing existing fiber infrastructure
- Improve quality, bandwidth and distance of video system
High degree of security –difficult to tap into or interfere with
Immunity to electrical interference such as:
- Electromagnetic interference (EMI)
- Radio frequency interference (RFI)
- High voltage interference caused by: Fluorescent lights, Card access door strikes and Outdoor lighting systems
Induced voltages caused by ground potential differences between locations
- Occurs in over 50% of all video security systems
