There are many different uses for video surveillance in Harrisburg. It can not only be useful in deterring criminals, but is instrumental in identifying perpetrators as well. It can also be used to monitor activity on roads, in parks, and in businesses in order to ensure safety. Fiber optic technology has changed the way information can be transmitted, resulting in higher quality, more efficient security technology.
Fiber Optic Basics
Fiber optic cables are actually bundles of hair-thin strands of optical fibers. These strands are made of optically pure glass, and when arranged into cables can transmit light signals over long distances, much further than coax cable. In simple terms, the fiber optic cable is able to transmit information for longer distances because the core through which the information travels is surrounded by a material that reflects the light. Instead of the light being absorbed and the information being stopped, it can reflect back to the core, allowing the information (light) to keep moving.
Fiber Optic Surveillance
A security system using video usually has a digital camera. The digital images are transmitted through the fiber optic cable, which is sent to a receiver. The distance that the images can travel depends on the quality, or purity of the glass that was used to make the fiber optic strands. More pure glass will result in a clearer image.
Data from the camera is fed into a fiber optic transmitter. This transmitter changes the information into coded light that can be sent fiber optically. The optical fibers send the light over the necessary distance. If necessary, a booster is used to amplify the light in order to transmit it greater distances. An optical receiver then decodes the light signal and changes it back into the original data format, which is an image that you can see. This system is so effective because it is done wirelessly. The images from multiple cameras can be viewed remotely.
There are many benefits to fiber optic video surveillance in Harrisburg. Most people using surveillance systems want to avoid the tedious task of combing through videotape when certain footage is needed. Since this system is wireless and digital, it allows all footage to be stored electronically. This makes it much easier to store and categorize information. This also allows software to be used in order to identify and track certain objects. This is an extremely beneficial technology for the military, especially for field communications and tactical missions. However, it is also useful in home and small business settings, as the systems becomes lower cost and easier to use. In addition to video, fiber optics can be used to connect sensors and intrusion alarms. This results in better overall security.
