The Scoop on CCTV Cameras
Closed Circuit Television, or CCTV, is primarily used in security systems and has seen big advances in recent years. It’s different from broadcast because the signal is not openly transmitted, its usually point-to-point links. Video cameras, which can be either digital or analog, transmit a signal to a designated portal and the owner of the system can watch the video feed in real time, or review it after a crime has already occurred. The footage would provide the police with evidence that would help solve the crime.
In factories and manufacturing facilities, cameras are used to insure governmental regulations and procedures are followed. This produces evidence that regulations are being followed. Another advantage is the events leading up to accidents that result in Workman’s Compensation claims or personal injury lawsuits are recorded which can protect the company from fraud
CCTV cameras are most frequently used for surveillance in places like banks, airports, banks, stores, and even casinos. Many homeowners also utilize hidden cameras in their security systems. CCTV makes it possible to monitor multiple locations from a central control room. Instead of several security guards being stationed in multiple locations, ideally one security guard could survey a bank of monitors receiving a feed from several hidden security cameras. When they noticed something awry, they would investigate and alert the authorities.
In the case of a crime that has already occurred, footage from a CCTV camera would be reviewed. Frequently cameras have recorded crimes like kidnappings, unrelated to the business that installed them, and provided leads for investigators. Most CCTV record to a file on a hard drive, but older, cheapers cameras still use VHS. Storage is a concern, and how long the footage should be kept before being erased is up to the owner of the system. Whether the security system records to video cassettes or directly to a hard drive, the footage is held for a predetermined length of time before being erased, ideally not without determining the camera didn’t record anything valuable.
As digital video recorders become more prevalent, hidden camera CCTV systems are stepping up to email alerts and motion detectors. There are currently many systems that can zoom and pan but are still relatively compact. With high-definition cameras hooked up to computers, it’s easy to track individuals or objects. Features like these are refereed to as VCA or Video Content Analysis.
The more prevalent CCTV becomes, the more the question of individual privacy rights versus the public interest are raised. Many metropolitan areas have such a high concentration of cameras that a person can no longer walk a city block without being caught on tape.
Some systems have weaknesses that hackers can exploit. Hackers can cross feeds or upload unrelated videos to replace your video. Moreover, all cameras have the possibility of being tampered with. Trying to protect the camera from vandalism or being neutralized can make them less effective. Laser pointers have reportedly been used to temporarily blind a camera. Also broadcasting another wireless signal at the exact same frequency can jam the camera. However, all of these things are easily counteracted with careful placement, and many manufactures have features that they claim make the cameras less vulnerable to vandals. These small limitations do not effect how valuable a hidden security camera can be. Choosing the correct camera can eliminate most of these types of concerns. Certain cameras are designed for outdoor use only while others are made only for indoor. They have a variety of ways of being mounted and have external appearances that make them recede in the surroundings and go unnoticed, and therefore not tampered with. A well-designed hidden security camera is difficult and time intensive to neutralize and is left alone and allowed to record the crime.
A security system that includes a hidden security camera that utilizes closed-circuit television is a valuable tool in defending one’s assets and property, as well as people, whether they are staff or loved ones.
