From the outside, this appears to look like any average full size Techvision standard DVR. However, on the inside this thin is buzzing with so much activity it really must be working hard. Regardless of the workload though, we have not experienced any dropped frames, no lost video or data, and no interference or disturbance in the quality of the recorded video, regardless whether it is analog, IP network, or HD-CVI. I like this full size version because our company has a tendency to request a lot of footage copies from me for what we do and this unit is large enough to hold an internal DVD burner yet still hold 6 large internal hard disk drives. There are multiple display options, remote access via your local network or the Internet, audio, alarms, and many other features that are very useful. If you have cameras that operate in different modes or all you need is analog coverage with a few camera for facial feature or individual identification, I think you'll find this DVR to work extremely well for you. If you read through some of the reviews, it's true what a lot of people say about the Security Camera King Technical Support Department. The crew is very knowledgeable and they want to help you with any issues you may have.
