NVR Security System – Pros & Cons

security camera systems incorporate the newest technology to provide an enhanced, feature-rich security system. Also known as POE security camera systems, NVR based systems are more flexible and complex than DVR systems.

As NVR systems process the video data at the camera rather than on the recorder, the cameras in NVR systems are much more robust than their DVR counterparts. NVR systems use IP cameras which are standalone image capturing devices. IP cameras each have a chipset which is capable of processing the video data which is then transmitted to a recorder. Unlike analog cameras, IP cameras are typically all capable of recording and sending audio as well as video. The more powerful hardware on IP cameras also enables improved smart functionality and video analytics, such as facial recognition.
Cable – Ethernet
Like DVR systems, NVR systems connect the camera to the recorder. However, how they connect the camera to the recorder is entirely different. NVR systems use standard Ethernet cables, such as cat5e and cat6, to transmit data. Professional installers prefer ethernet cables due to the number of advantages compared to coaxial cables:
Ethernet cable powers the camera using Power over Ethernet (PoE), which means your camera needs one cable running to capture video, audio, and power the camera, thus eliminating the need for messy splitters like a DVR system.
Ethernet cable tends to be easier to route and terminate because it is thinner and has a smaller connector allowing for less drilling.
Ethernet is cheaper than coaxial cable and much more readily available, making cable replacement or system expansion more accessible and affordable. Many modern homes and businesses are being built wired for Ethernet, making installation even easier.
An added advantage of Ethernet cable is that every camera on the system can transmit audio since Ethernet can send audio data natively.
Cables do not need to run between every camera and the recorder. They need to be on the same wireless network. Installation is more straightforward and cleaner as multiple cables aren’t required.
Despite a shorter max Ethernet cable length, 328ft or 100m, network switches can be used to extend total distance without impacting image quality.

What Types Of DVRs Are Available?

Using Digital Video Recorders will be the best option. If you have a surveillance camera system set up at your home or business, you would like to record, and archive recorded footage.
A DVR system is a favoured method to store recorded security footage. It contains software, storage units, and a computer hard disk incorporated in a single piece of equipment. Digital Video Recorders can take video feeds and convert them to digital. They can also store hours of footage, and they can also apply motion detection to start recording.
DVRs come in different sizes, and they are designed to meet various security applications. They can be small, easy to carry, and conveniently be paired with a hidden surveillance camera, or they can be as big as a personal computer. Some DVRs can be connected to a remote network, which allows you to view footage over the internet.
Types of DVR
Embedded DVRs This type of DVR system is a stand-alone piece of equipment that accepts analog CCTV camera inputs for compression and stores footage on a local HDD. The operating system and DVR software are on the chip, and it has a hard drive to store recorded images. Embedded DVRs usually have several internal hard-drive spaces and more external hard-drive connections for extended recording times.
Hybrid DVRs Since they support both CCTV and IP cameras, users do not have to limit their camera recording options. It is recommended to install analog cameras in less vulnerable areas and install high-resolution IP cameras in high-level security risk areas. The essential advantage of using this type of DVR system is to manage and record both analog and IP surveillance cameras.
