Campion-FAQ q What is Closed Circuit Television (CCTV)?

Closed Circuit Television

Campion-FAQ a CCTV or Closed Circuit Television refers to a visible or covert video system intended for only a limited number of viewers. In Closed Circuit TV (CCTV), the picture is viewed or recorded, but not broadcast. It was initially developed as a means of security for banks and casinos; however, today it has been developed to the point where it is simple and inexpensive enough to be used with Home Security Systems, and for everyday surveillance. More specifically, CCTV is a television transmission system in which live or prerecorded signals are sent over a closed loop to a finite and predetermined group of receivers, usually as scrambled radio waves that are unscrambled at the point of reception. CCTV takes numerous forms and performs a wide range of functions ranging from image enhancement for the partially sighted to the transmission of pay-per-view broadcasts. Although cable television is technically a form of Closed Circuit TV, the term is generally used to describe systems with more specialized applications than a standard broadcast or cable television. Such specialized systems are not subject to regulation by the Federal Communications Commission (FCC); however, Security Cameras using scrambled radio waves are in fact subject to common carrier tariffs and FCC conditions of service.

Campion-FAQ q Why would I need a Surveillance System?

Why Surveillance System

Campion-FAQ a Surveillance systems are used for Security, Theft Prevention, Protection, Employee Monitoring and many other purposes. For businesses, a surveillance system may be used for monitoring employees and productivity, safety of employees, documenting customer visits, preventing fraud and theft, and providing court documentation if theft were to occur. For Homes, a surveillance system may be used for watching your children while you are at work or inside the house, watching your pets (for extreme pet lovers), monitoring your home while you are away on a trip, watching for delivery of packages, monitor a philandering spouse, or making home videos of those times when you just don't have a camera handy. In the world today, the need for a CCTV Surveillance System is increasing. Suspicious activity can be recorded and reported immediately to the authorities. Cameras also help us catch the perpetrator or save ourselves from embarrassment of false accusations.

Campion-FAQ q What is CCTV's primary function?

Campion-FAQ a CCTV is most commonly used for surveillance. Security Cameras are now universally featured in many public and private institutions, from a correctional facility to the convenience store. In prisons, reduce the costs of staffing and operating observation towers and make it possible to maintain a constant watch on all areas of the facility. CCTV has become so much less expensive over the years that both large and small stores are able to install cameras as a deterrent against theft and robbery, a practice, which municipal authorities have adopted as a way of curtailing crime in public housing and even on city streets. In many areas of the country as well as in Europe, Security Cameras have been placed in highly crowded public areas as a security measure against terrorism.

Campion-FAQ q What are some other common uses of CCTV?

CCTV Common Use

Campion-FAQ a CCTV has many industrial and scientific applications outside of the world of surveillance. Electron microscopy, medical imaging and robotics are all common uses of CCTV, however, the term "Closed Circuit TV" does in fact most often refer to security and surveillance camera systems. Other common forms of CCTV include live on-site video displays for special events such as various conventions, arena sports and concerts as well as pay-per-view telecasts of sporting events such as boxing and pro wrestling. Also a common user of CCTV is "in-house" television channels that broadcast to very small and specific receivers such as in hospitals, airports, racetracks, schools, malls, grocery stores, and municipal buildings.

Campion-FAQ q Are all DVR's the same?

Campion-FAQ a Absolutely not! There are several factors that are critical to consider when purchasing a DVR, especially when comparing price. The most important factors to look at are the number of cameras supported, frames per second (fps), compression technology, hard drive space, network connection / remote viewing capability, motion detection, scheduling, and ability to save video and audio to a CD or flash drive. You should also look for easy and comprehensive search capabilities (check out our 'Smart Search' technology) and audio support. The setup and user interface should be intuitive and easy to operate.

Campion-FAQ q What is frames per second?

frame per second

Campion-FAQ a The frames per second (fps) relates to how many pictures the DVR will record in a second. Real time recording is about 30 fps on each camera. To calculate the fps per camera take the total fps in the system and divide it by the number of video inputs. For example, a 60 fps digital video recorder with 4 video inputs would result in about 15 fps per camera. The technology has finally gotten to the point now where real time recording is affordable. If you are recording cash registers or something similar then you should definitely invest in real time recording.

Campion-FAQ q How big a hard drive do I need?

Campion-FAQ a The amount of hard drive space is very important because it will limit how many days of recording you can store before the system has to start recording over the oldest video. Each DVR will have its storage capacity listed in the specifications. But this calculation is just a rough estimate as there are many factors that affect hard drive use. The most critical factor being the compression format used by the DVR (for more info on compression formats click here). But also the type of cameras that are connected to the DVR make a difference (specifically the chip size and resolution) and also the features that are selected on the DVR. If you use the scheduling or motion detection features or tune down the frame rate that will extend the storage capacity of the unit. Even the field of view (what you are recording) will affect the storage capacity - the more complex the image, the more hard drive space it will take to capture the complexity.

Campion-FAQ q What is Remote Surveillance?
