To have an improved, feature-rich surveillance system, NVR security camera systems leverage the newest technologies. NVR based systems are also known as POE security camera systems, which are more versatile and complex than DVR systems.
Camera Type – IP Camera
The cameras in NVR systems are much more stable than their DVR counterparts, since NVR systems process the video data on the camera rather than on the recorder. NVR systems use IP cameras that are instruments for capturing standalone images. Each of the IP cameras has a chipset that can process video data that is then transmitted to a recorder. IP cameras are usually capable of capturing and sending audio as well as video, unlike analog cameras. Improved smart features and video analytics, such as facial recognition, are also possible with the more efficient hardware on IP cameras.
Cable – Ethernet
NVR systems attach the camera to the recorder, much like DVR systems. How they attach the camera to the recorder, however, is completely different. Standard Ethernet cables, such as cat5e and cat6, are used by NVR systems to transmit data. Owing to the number of benefits compared to coaxial cables, professional installers prefer ethernet cables:
- Using Power over Ethernet (PoE), the Ethernet cable drives the camera, ensuring your camera requires one cable running to capture video, audio, and power the camera, removing the need for messy splitters like a DVR device.
- As it is thinner and has a smaller connector that requires less digging, the Ethernet cable appears to be easier to route and terminate.
- Ethernet is cheaper and much more readily available than coaxial cable, making cable replacement or system expansion more available and affordable. Many new homes and companies are being built wired for Ethernet, making it much easier to install.
- An additional benefit of the Ethernet cable is that, because Ethernet can send audio data natively, any camera on the device can transmit audio. Between any camera and the recorder, cables do not need to run.
- It is important for them to be on the same wireless network. As multiple cables are not needed, installation is simpler and cleaner. Network switches can be used to increase the total distance without affecting image quality, despite the shorter peak Ethernet cable length of 100m.
The recorder in an NVR system does not process video data, unlike a DVR system. In the camera, the stage is completed before it is transmitted. NVR recorders are used only to store and screen video.
As security cameras do not actually have to be physically attached directly to the recorder, NVR systems are generally more versatile. IP cameras just have to be on the same network instead. As such, on the same network, you might potentially have cameras all over the world that link to your NVR which can then be used as a comprehensive device.
Image & Audio Quality
As NVR recorders receive a pure digital signal from the cameras, at the same resolution, the video quality is higher than compared to a DVR. In addition, all cameras with microphones were able to capture audio to the NVR as Ethernet cables hold audio.
