What is CCTV

What is CCTV & How Does it Work?

CCTV stands for closed-circuit television. This surveillance technology consists of several components, including Analogue cameras, Network video recorders, and cloud-based video surveillance. It has many applications, from monitoring traffic to preventing vandalism. The following are some examples of CCTV. The benefits of CCTV surveillance are numerous. In addition to being useful for police investigations, CCTV systems are beneficial for business owners because they can keep an eye on employees and protect property from damage.

Closed-Circuit Television

Closed-Circuit Television

Closed-circuit television, also known as video surveillance, is a form of surveillance that uses one or more cameras to transmit a video signal to a monitor. It can provide a variety of benefits, including safety for students and faculty, as well as instructional benefits outside the school. For example, the use of closed-circuit television in education allows teachers to monitor students’ behavior in a safe environment and helps foster reading skills.

A closed-circuit television system consists of multiple video cameras connected to a central processing unit. The images captured by the cameras are stored and are available to the viewing public via a monitor. These systems are highly flexible and can be customized to meet specific needs. They are used in a variety of settings, from small businesses to large corporations. Public buildings and parking lots are common places to install closed-circuit television systems, check out the post right here.

Network Video Recorders

There are two types of Network video recorders (NVRs): basic and high-end. While the former is primarily used for the corporate market, the latter is aimed at home and small businesses. In either case, NVRs use UTP (cat5e) cable and a router to communicate with each other. This enables the recording of video and storing it on a cloud. Adding more cameras to a networked system is also possible.

As far as price and performance goes, the Anpviz NVR is probably the most affordable option. It has a price tag of $299 but features comparable to a top-tier brand. This model supports up to 16 IP cameras at once and has a 1-year warranty. Lorex makes a more premium network video recorder that is ideal for home use. With this price, the Anpviz NVR can record up to 16 cameras at a time.

Analogue Cameras

While IP advocates might argue that the addition of more IP cameras on an existing network is enough, this will still require the installation of a switch to link the IP cameras. You may need to purchase a larger switch or POE adapters, depending on the amount of cameras you’ll have. Then, you’ll need to consider the amount of bandwidth your local area network can handle, because video consumes a lot of bandwidth. The amount of bandwidth your cameras use will vary depending on their resolution, compression method, and how much movement is in their field of view.

One of the primary disadvantages of analogue cameras is that they’re less expensive than their IP counterparts. Analogue cameras are easier to install and operate, but their picture quality is low. Analogue cameras cover less space than IP cameras and do not have data encryption technology. Analogue cameras may also be susceptible to digital invaders. A recent study suggests that IP cameras are more effective in low light environments, while analogue cameras are less reliable.

Cloud-Based Video Surveillance

Cloud-Based Video Surveillance

Choosing cloud-based video surveillance can give you peace of mind. Not only can you view footage from anywhere, but you can control recording settings, monitor access and manage your entire system from a single location. This type of surveillance system is ideal for businesses, as it helps you to keep an eye on many aspects of your business without having to visit a single site. The benefits of cloud-based video surveillance are numerous and will greatly improve your business’s security and profitability.


Using the cloud to store video surveillance footage is an excellent idea because it gives you virtually unlimited storage capacity. But cloud-based storage can be expensive, so you’ll need to shop around to find the best deal for your needs. In addition, determine how long you’ll keep footage. Remember that the longer you store video, the more you’ll pay.
