The NVR has small stand-up metal feet to get the base somewhat off the surface below. So the fan does actually work fine like this, but some nice rubber feet for the NVR will improve airflow a lot and reduce noise further. I couldn't find any feet in the bit box, but will probably locate some. If you were fitting new fan meshes you'd definitely want the additional clearance. To summarize, the DS-7608NI-K2/8P and DS-7608NI-I2/8P are both excellent units and are remarkably similar in spec. Choosing one for your system really comes down to personal preference and we hope that with the above information we have made it a little easier for you to choose one for your system! HDMI Output 4K (3840 × 2160)/60Hz, 4K (3840 × 2160)/30Hz, 1920 × 1080/60Hz, 1600 × 1200/60Hz, 1280 × 1024/60Hz, 1280 × 720/60Hz, 1024 × 768/60Hz Below we'll take a look more closely at the key features and specification. I'll highlight the main differences.

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: HDMI Output 1-ch, 4K (3840 × 2160)/30 Hz, 2K (2560 × 1440)/60 Hz, 1920 × 1080/60 Hz, 1600 × 1200/60 Hz, 1280 × 1024/60 Hz, 1280 × 720/60 Hz, 1024 × 768/60 Hz If you're interested in which is the best 4-Channel NVR then please take a look at last weeks article.By Device All channels, 4 MP (when enhanced SVC mode is enabled, up to 8 MP) video analysis for human and vehicle recognition to reduce false alarm In the next couple of weeks I'll also be looking at 16 and 32 channel Hikvision NVRs for bigger systems. 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. Adopt stream over TLS encryption technology (enhanced SDK service and RTP over HTTPS protocol) which provides more secure stream transmission service (max. 128 Mbps TLS stream outgoing bandwidth) 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 a 83.7% saving over H.264 and a 66.8% saving over H.265.

Cutting a hole for the fan (especially if you had a second hard drive so couldn't use the existing vents) might be good. There is lots of room when the power supply comes out to do this in either the lid or the base. There are enough holes in the base for this to work fine without if you don't need the second drive, but a nicer hole, a fan gasket and some fan mesh would be better. Cutting neat holes in aluminium isn't straight forward at home, so a fit from the outside fan mesh which covers your work is a nice thing.ANPR ready (Hikvision's recommended ANPR camera is the Hikvision DS-2CD4A26FWD-IZS. For more information on ANPR please see our Hikvision ANPR setup tutorial.) 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.
