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.
