Types of CCTV Systems

There are two types of CCTV security cam systems: Analog and IP (network/digital).

Analog Surveillance Systems

Analog security systems are composed of analog cameras connected to a digital video recorder (DVR) via transmission cables. The video recording system receives the video input, compresses the information, then stores it on a hard drive. This setup also permits you to transmit the video over the internet for remote viewing, either in real time or afterwards. In an analog system, the DVR is responsible for compressing, converting, storing, and streaming video signal. It also manages the camera’s integrated capabilities, like movement detection, alarm inputs, daily schedules, and more.

IP Surveillance Systems

In an IP configuration, the digital camera negates the need for a DVR, compressing, converting, and streaming the video over a web connection. With this setup, the video can be streamed directly to a private monitor or an NVR (network video recorder).

Where are CCTV Cameras Used?

CCTV was first utilized by scientists in the 1940s to observe the launch and development of rockets. Since then, it has evolved to become one of the most common forms of security in the world. From public structures to private homes, strategically placed security electronic cameras capture events as they occur, along with recording video footage for later viewing. CCTV is frequently used for:

Business Security

CCTV technology works as a fantastic crime deterrent and even serves to gather evidence in the instance a crime is committed on your business’ property. Banks, offices, gas stations, and other retail businesses frequently attract crime—but this can be deterred by up to 70% simply by installing a security camera or two. CCTV cameras have been used for decades to safeguard assets like money, business equipment or merchandise, intellectual property, and more. Video surveillance in the workplace can also keep an eye on employee well-being, productivity, and interaction.

Home Security

Security cameras can prevent crime at home, too. Prevent vandals, burglars, and other criminals from breaking and entering or trespassing by installing CCTV cameras to capture their image. CCTVs can also be used at home to keep an eye on any staff that you may have around the house, such as nannies, maids, or chefs.

Tracking Vehicles and Traffic

Police utilize security electronic cameras to keep an eye on traffic at busy roads and intersections. The evidence gathered by CCTV cameras grants law enforcement the ability to carry out their job, penalizing those who break the law by speeding or running a red light and allowing the innocent party in a vehicle collision to seek justice.

Will CCTV Work Without Internet?

A web connection is just needed when the video footage needs to be accessed remotely. Although utilizing web connection has its benefits, it is definitely not a requirement.

While using all the features of an internet-connected CCTV system are certainly advantageous, there are some locations where it is not possible to utilize them like for homes in rural areas, such as farms and off-the-grid homes, where internet and electrical energy are a scarcity. The ability to use a CCTV video camera in places with no web and electrical power allows everyone to secure their residential or commercial properties, be it metropolitan or rural locations.

In truth, some people choose not to link their CCTV systems to the internet given that it makes them more vulnerable to cyber-attacks and hacking, as criminals can hack the system and take control of their CCTV feed.
