NVR VS. DVR: What Sets Them Apart?

Nowadays, everyone takes the necessary steps to secure their commercial and residential properties. While purchasing a security system, you will encounter the terms NVR and DVR. You might wonder what they mean. NVR stands for Network Video Recorder, whereas DVR is the short form of Digital Video Recorder. They are both commonly used surveillance systems today, which might make it challenging to choose one of them. Don’t get confused, though, as we will discuss the difference between NVR vs. DVR systems in this blog.

NVR VS. DVR: Are They Different?

NVR and DVR systems are both surveillance systems responsible for video recording, but they differ in how they process the footage. The way of handling raw video data is the primary difference between the two. The DVR camera system records the video data at the recorder. In comparison, the NVR camera system encrypts and processes data at the camera first. Then, it sends it to the NVR recorder for storage and remote viewing. Therefore, they need different cameras since their video processing techniques differ.

The Basic Components & Features of NVR & DVR Systems

Popularly known as the POE security camera system, NVR is comparatively more flexible yet complex than the DVR system. Usually, it only works with digital footage.

Camera Type
A significant difference between DVR and NVR systems is their camera type.

NVR systems use IP cameras, which process the footage before sharing it with the recorder. Not only do IP cameras transmit videos or images, but audio as well. In addition, the advanced hardware in these systems allows intelligent video analytics. Thus, you have features like license plates and facial recognition with them.

DVR systems use analog security cameras, commonly known as CCTV cameras. The recorder processes raw video data after receiving an analog signal from the analog camera. CCTV cameras are less flexible than NVR camera systems, but they are less complex too. Moreover, DVR systems are less expensive due to the camera.

Both NVR and DVR systems connect to the camera via cables.

NVR systems use standard Ethernet cables like Cat5e or Cat6 to connect the IP camera to the recorder. Although they can only run up to 100 meters, Ethernet cables are relatively easier to set due to their thin size and shape. Furthermore, they are cost-effective and readily available too.

DVR systems connect the camera to the recorder with the help of a coaxial BNC cable. They are wider and stuffer in comparison to Ethernet cables. Although they can run up to 500 meters, coaxial cables do not supply power to the camera. Also, they only transmit video to the recorder. Thus, another cable is used to carry electrical signals.

Another difference between the DVR and NVR systems is marked by the function of their recorder.

The NVR system processes the video at the camera before transmission. Hence, the recorder is only responsible for storing and viewing the footage.

On the other hand, DVR systems have some requirements for the recorder. Firstly, they rely on AD encoders to process the raw video data. Thus, every camera must be connected to the recorder and a separate power source. Whereas NVR systems only require that all cameras connect to the same network.

Key Takeaway

In conclusion, when it comes to NVR vs. DVR, both surveillance systems are reliable. The difference between DVR and NVR lies in their implementation and design. Processing raw data, setup, cameras, and costs are some aspects that really set them apart. NVR systems are easier to install and have rich picture quality plus flexibility. They even support audio recording. However, they are a little expensive compared to DVR systems. Ultimately, you should opt for a security system that suits your property’s needs and budget better.
