Hikvision 4 channel NVR with POE (DS-7604-NI-SE-P)

Product Information

The -K and -I series are relatively similar in spec 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:

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

Data protection through Redundant Array of Independent Disks (RAID), Automatic Network Replenishment (ANR), N+1 or N+M hot spare, and cloud storage Advanced streaming technology enables smooth live view and data self-correction in poor network conditions 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 are needed by 3MP, 5MP and 8MP cameras from the Hikvision EasyIP 3.0 (G1) Family: There are no newer variants to look out for e.g. when the 7604 NVR was 'improved' Hikvision added a (B) suffix.

In the next couple of weeks I'll also be looking at 16 and 32 channel Hikvision NVRs for bigger systems. As an IT professional I would not replace a core part of any network with equipment that must be approaching end of life and I wont do that with an NVR either. I feel exactly the same I currently only have one DS-2CD2385G1-I Hikvision IP Camera and I am planning to get an additional Colorvue camera in the next weeks, I am also planning to gradually replace my 6 Blink cameras and was hoping to use Hikvision cameras however the situation with NVRs is putting me off. Decoding capacities: 2 channels @ 32 MP, 8 channels @ 8 MP, 16 channels @ 4 MP, or 32 channels @ 1080p 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.In November 2017 there was a new V4 firmware release for Hikvision NVRs which changed the user interface dramatically. However, this firmware was only made available to the -I series NVRs and this is still how the situation remains today. We aren't sure whether this firmware will be made available for the -K series. To summarize the above points, either the -K series or -I series NVR would be a great choice unless you were looking to use above an 8MP camera.
