What is a DVR?
DVR stands for Digital Video Recorder. It is a device that records video from security cameras. DVR systems use analog cameras. These cameras send video signals through wires to the DVR box.
The DVR then changes the video into a digital format. It stores the video on a hard drive inside the DVR. You can watch the video later on a screen or computer.
How Does A Dvr Work?
- Cameras connect to DVR using coaxial cables.
- DVR processes and records video on its hard drive.
- You can view live or recorded video from DVR.
DVRs are often used with older cameras. They are common in many homes and businesses. The system is simple and easy to set up.
What is an NVR?
NVR means Network Video Recorder. It is a device that records video from IP cameras. IP cameras send video through a network or internet.
The NVR receives video digitally. It saves the video on its internal hard drive. You can watch videos live or later through a computer or phone.
How Does An Nvr Work?
- IP cameras connect to NVR via a network cable or Wi-Fi.

NVR systems are newer and more advanced than DVRs. They work well with high-quality cameras. Many people use NVR for modern security setups.
