CCTV Stands for closed-circuit television. It is a system that allows you to keep a close watch on what’s going on in and around your loved once, your business or any places which you want to secure from any incidents. CCTV Cameras allows you to view events live and recorders archive footage for later reference. In earlier days of CCTV ,it was used as post analysis tools but now in combination with artificial intelligence & IoT, CCTV is used to detect and prevent any crime or incident before of its occurrence.
CCTV System is consist of main parts likes camera,video recorder,storage device,Power supply & cables. Based on camera system there components get changed accordingly. Below are In CCTV there are mainly four technological solution which are as below.
Cost effective solutions
Easy installation
Low storage
Good resolutions
Long transmission
Economical then IP
Scalable
Lower cable cost
Best resolutions.
Flexibility
Easy installation
Less cabling
In recent time technology upgrades to fast. Analog Solution served long time in electronic security industry but as new options arrived, it get abandoned by market. Analog was replaced by HD Solution which is good in resolution & having long transmission capabilities. But HD Solution is also having some limitation like difficult to use in big projects as it is difficult to scale.It is difficult to maintain big HD setups as compared to IP solution. Hence in big projects like city surveillance,railway station,ports,malls, etc. IP Solution is adopted by integrator’s. In IP Cameras cabling can be reduced by introducing intermediate POE Switches which provide power & deliver data through same cat 6 cable.
In current times as per condition & project requirements wireless technology is widely used in big projects to avoid bulky cabling mess.Although in wireless technology IP cameras are used but for data transmission on long distance like more then 300-400 meters. wireless transceivers are used. which provide great stability to system.In electronic security industry CCTV cameras play very vital and essential role. Now days CCTV System is integrated with other system like Access control, Fire alarm system & home automation to provide complete 360 degree security solution. It helps a lot to government security agencies to resolve critical cases by providing video footage’s as evidence.
CCTV cameras are broadly classified in two types i.e. Indoor Cameras & Outdoor Cameras.In this two segments there are so many types based on according to shape, size, functionality, specialization. The CCTV system is technologically upgraded in such a way that for every type of situation there is one type of camera.and for this all credit goes to artificial intelligence which gave us,motion based cameras,thermal cameras,body worn cameras,face recognition cameras,Automatic number plate recognition cameras (ANPR). Cameras with function like intrusion detection, trip wire etc.If we have internet connection then we can monitor cameras from any where in world.
