Hikvision DVR explanation - Everything about analog surveillance with Hikvision | Central alarm

HikvisionDVR explanation– a DVR (Digital Video Recorder) is the recording center for analog surveillance cameras. Although IP cameras with NVR are becoming increasingly popular, DVR systems are still relevant, especially for upgrading existing analog installations. In this article we explain everything aboutHikvisionDVR systems.

What is a Hikvision DVR

AHikvision DVRreceives video images from analog cameras via coaxial cables (RG59 or RG6). The DVR converts the analog signal to digital data, compresses it with H.265 and stores it on an internal hard drive. ModernHikvisionDVRs support TurboHD technology, which allows higher resolutions over coaxial cable: up to 8MP on 4K TurboHD systems.

DVR vs NVR: what are the differences

The biggest differences between a DVR and an NVR are the type of camera and the cable infrastructure. A DVR works with analog cameras and coaxial cables. An NVR works with IP cameras and network cables. DVR systems are cheaper to purchase and ideal for reusing existing coaxial cabling. However, NVR systems offer more flexibility, higher resolutions and easier integration with smart home systems.

Hikvision TurboHD: analog to HD

Hikvisiondeveloped TurboHD as a technology that enables high definition (HD) video over traditional coaxial cable. TurboHD cameras deliver resolutions of 1080p, 3K, 4MP, 5MP and even 4K over existing coaxial cabling. This makes upgrading an old analog system to HD simple and affordable, without having to install new cables.

How many channels do you need

HikvisionDVRs are available in 4, 8, 16 and 32 channel versions. Choose the number of channels based on the current and desired number of cameras, plus some room for future expansion. A 4-channel DVR is suitable for a simple home installation. A 16 or 32 channel DVR is ideal for businesses and stores with multiple surveillance points.

Set up DVR: the basic steps

Connect the coaxial cables to the BNC input ports of the DVR. Connect a monitor and turn on the DVR. Go through the installation wizard, set the date/time and create a password. Then go to the camera overview to check whether all cameras provide images. Then set the recording schedule and connect to the Hik-Connect app for mobile access.

When should you choose a DVR

A DVR is the right choice if you want to reuse existing coaxial cabling, if your budget is limited, or if you want a simple system without network configuration. For new installations without existing cables, an NVR with PoE cameras is usually the better long-term investment.
