What is the difference between CCTV and DVR?

There are many different types of security cameras on the market these days. Two of the most common types are CCTV (Closed Circuit Television) and DVR (Digital Video Recorder). Both have their own advantages and disadvantages, so it’s important to understand the difference before choosing which one is right for your needs.

CCTV cameras are the older technology of the two. They work by sending a signal from the camera to a monitor or recording device. The main advantage of CCTV cameras is that they are relatively simple to set up and use. They are also very affordable, making them a popular choice for small businesses and homes. However, CCTV cameras can be less reliable than DVR cameras, and the quality of the image is often not as good.

DVR cameras are newer and more advanced than CCTV cameras. They work by digitally recording video footage onto a hard drive or other storage device. DVR cameras usually offer better image quality than CCTV cameras, and they are also more reliable. However, they can be more expensive than CCTV cameras, and they can be more difficult to set up.

CCTV is a closed-circuit television system that is used to monitor an area. A DVR is a digital video recorder that records footage from CCTV cameras. The two systems are often used together to provide security for a home or business.CCTV cameras are typically mounted in strategic locations and can be either fixed or portable. DVRs are usually located in a central location and are connected to the CCTV cameras. The footage from the cameras is then recorded onto the DVR.The main difference between CCTV and DVR is that CCTV only provides surveillance while DVR also provides recording capabilities. This means that if there is an incident, the footage can be reviewed later on.
