Hikvision NVR

Hikvision NVR  ( network video recorders) are similar to a DVR with one major exception, the signal is carried digitally between the camera and the recorder ( NVR) much like linking your office computers and mobile devices to your WIFI at home whereas DVRs ( digital video recorders) only record the signal in digital format. This can be compared to the digital TV switchover which ended the "snowy" or ghosting pictures. The same applies to digital CCTV systems. Any CCTV product attached to the NVR has to be "network " or "IP" ( internet protocol) compatible.

You can tell the difference between an NVR and a DVR from the back connectors. A Hikvision NVR has RJ45 connectors also known as network or ethernet connectors as shown in the picture below.

The downside of IP CCTV systems is the cost, difficult to fault find if you don't have little some networking skills or can't use a computer. Also, you can't take out an NVR made by one manufacturer and replace it with another. The same applies to IP cameras.

Nearly all of our Hikvision NVRs have built-in PoE ( power over ethernet ) which means there is no need to buy a power supply to power the cameras as its built into the NVRs Only one cable is needed between the IP camera and the Hikvision NVR, this cable is called CAT5/6 or network/ethernet cable as shown in the picture below. This Ethernet cable can also carry sound and other control signals and also have additional devices connected to the IP cameras such as control relays for switching other devices.

The Hikvision IP cameras can also be connected to the NVR using a power line plug or a HomePlug as its sometimes called. This is very useful when you have an area where it's difficult or impossible to cable such as a garage next to your home. You can buy a home plug kit and one plug into your mains socket near your router and the other in the mains socket in the garage. You will also need a power supply to power the camera which would connect to the homepage.

There are currently 2 main choices of  Hikvision NVR, The "K"  series which supports up to 8MP Hikvision  IP cameras and the "I" series Hikvision NVR which supports up to 12MP. For example DS-7608NI-K2/8P or DS-7608NI-I2/8P. The "K" Series NVR is designed to be a middle-level product while the "I" series is the high end product. 

The -K and -I series are relatively similar in specifications so it can be hard for users to decide which unit is best for their system. In this article, we'll hopefully make the decision easier and cover the main differences focusing on. In brief the I series has more processing power, faster processor, supports more analytics, supports BNC monitor out, Supports EPoS overlay, has alarm inputs and outputs.

Some Hikvision NVR Terminology

Recording Resolution - The resolution of a camera tells us how many million pixels will be in its images. 8MP = 8 million and 12MP = 12 million. Currently, the highest resolution available in Hikvision IP Camera is 8MP. This is really high quality and pretty much the best consumers can get on the market for a CCTV system.

12MP cameras are rare and tend to be something like a DS-2CD63C2F-IVS Hikvision Fisheye camera. However, 12MP spread across a 360° field of view isn't actually very impressive and the image would seem of low quality.

Incoming Bandwidth and H.265+ - You may be wondering how you're supposed to know whether 80 Mbps worth of incoming bandwidth is enough bandwidth to support your 8 cameras. Below is a guide to roughly how many Mbps is needed by 2MP, 4MP 6MP & 8MP IP cameras.

With H.265+
There aren't any exact measurements for how many Mbps are used by cameras running H.265+ yet but Hikvision's literature tells us that H.265+ offers an 83.7% saving over H.264 and a 66.8% saving over H.265.

In conclusion, you could use 8 x 8MP cameras on both the -K series NVR or the -I series and have no incoming bandwidth issues. However, when fully loaded with all 8MP cameras, the NVR would be less responsive and play of multiple cameras at the same time would also be limited.


H.265+ also offers a huge saving on storage needs meaning that hard drives will reach maximum capacity much slower. Seagate surveillance hard drives are recommended for CCTV use and are available in a range of sizes from 1TB-10TB. I use this Hikvion hard drive storage calculator to help customers choose a hard drive size.

Outgoing Bandwidth - This tells us how much outgoing traffic the NVRs can handle. This covers things such as remote viewing your system from a browser or from an app such as Hik Connect. If you'd like to know how Hik-Connect works you can take a look at our post explaining Hik-Connect.
