Surveillance equipment has evolved over the years and has steadily become an automated system. You no longer require to post people at strategic locations 24×7 for surveillance be it in-home or office. There is a whole spectrum of surveillance equipment available now, which can do the job of surveillance personnel, if not better. What started with basic recording has now evolved into modern surveillance systems that are capable of collating and evaluating footage with the help of software. Then some cameras can provide imagery even beyond the visible spectrum of light. There are pieces of equipment using x-rays and gamma rays for more effective surveillance.
Types Of Surveillance Equipment
Audio Surveillance Equipment
These are usually small microphones or digital voice recorders that you can easily conceal. Moreover, you can use these devices for recording conversations. In some cases, people use parabolic microphones to receive sound from one direction only. Such tools are useful in massive gatherings where there is a lot of background noise. There are mouthpieces within some phones which can be remotely activated for recording noise.
Signals Tracking Surveillance Equipment
Radiofrequency ID tags that can be placed on individuals or objects and tracked from a distance are also a kind of equipment. These tags can transmit unique identifying signals. Scanners pick this signal and then detect the object. Such a surveillance system is also possible over a wide area. In those cases, larger transmitters like GPS units and satellite networks can be of use to the same thing but over a more excellent range. This is often done to track vehicles or wildlife.
Signal Interception Surveillance Equipment
Intercepting electronic/radio communication is a kind of surveillance that defense and also security establishments often employ. Moreover, there are various types of signal equipment that these establishments use to accomplish their job. Due to this reason, they usually attach electronic bugs to telephone switch boxes and lines. This automatically routes the calls through their monitors, and they can listen to the communication as and when required. There is radio equipment in which people use to intercept conversations transmitted over airwaves such as mobile communications.
Video Surveillance Equipment
Streaming digital footage from multiple cameras fed into a monitor is like Closed Circuit Television and also people use it in video surveillance. You need to put up a number of cameras at strategic locations for this purpose and connect them to a monitor. Such a system can be used in home, office, and also every other conceivable premise where there is a computer and Internet access. Moreover, with video surveillance equipment, one can get real-time access to different areas of a place where cameras are mounted.
Micro cameras are the best to take snaps or record videos. This equipment can get conceal in stuff like earphones, watches, etc. This is very useful when one needs to record videos or take snaps secretly.
Bug Detectors And Hidden Camera Finders
Furthermore, bug detectors and secret camera finders are an integral part of surveillance and counter-surveillance. Moreover, security agencies and even others make use of such equipment to make sure that nobody is keeping a watch on them.
