NVR System Components - Pros, Cons, Differences: DVR recorders also have a fixed number of audio input ports, which limits the number of cameras that can record sound.

Audio Limitations: Standard coaxial cables don’t natively transmit audio signals - an added RCA connection is required to support it.

As a result, every camera in a DVR system needs to be connected to the recorder as well as a separate power source.

AD Encoder: DVR recorders rely on AD encoders to process raw video data from the camera into viewable footage.

Audio is a limitation since standard coaxial cables are not able to support audio transmission.

Coaxial cables are wider and stiffer than Ethernet cables, which can make installation a challenge.

This means two types of cables are needed - one for power and one for video transmission.

Coaxial cables - unlike PoE cables - do not supply power to the camera.

Coaxial Cables: The analog camera connects to the DVR through a coaxial cable, which can run up to 500 meters but could result in some limitations.

Compared to an NVR system, most DVR cameras are less complex and expensive. Analog cameras transmit analog signals to the recorder, which then processes the video data. The reason why DVR security systems are typically priced lower compared to NVR systems is due to the camera.

Analog Cameras: DVR systems typically use analog security cameras (otherwise known as CCTV cameras).Unless they’ve been reconfigured, the DVR connects to an analog CCTV system via a coaxial cable, while the NVR connects to an IP camera system over an Ethernet or WiFi connection.ĭVR System Components - Pros, Cons, Differences: DVR systems process data at the recorder, while NVR systems encode and process data at the camera before transmitting it to the recorder for storage and remote viewing. A DVR converts analog footage into a digital format, while an NVR typically only works with digital footage. The main difference between the network video recorder (NVR) and digital video recorder (DVR) is in how they process raw video data.
