[1x SATA] Good PVR - lots of features.

[128] I bought this model to upgrade from my DS-7608NI-E2/8P. This one has more storage compacity and uses the latest software/firmware. I had no problem setting this one up. The wizard work well for me. The menus were in a different format older NVR but I was able to figure them out with no problem.

[1x SATA] I had an older/cheaper Hikvision 1TB NVR that didn't have the latest software or capabilities. This unit is much easier to use, especially when you're looking for a specific event. Initial setup was a breeze. I took the older 1TB hard drive and installed into this unit. Instantly recognized it. What I don't like about it - and I've seen/read this from other users...the cooling fan is LOUD. Luckily my unit is in a utility room (washer/dryer) and the noise doesn't bother us. I did have a minor setup issue recognizing my newer Hikvision cameras - B&H technical got Hikvision USA on the phone with me. I didn't have the latest firmware loaded. New firmware fixed the issue. I also have the newest Hikvision WiFi doorbell connected to it. I highly recommend this unit if you're wanting to have the latest tech, reasonable costs, and a more capable NVR.

[External] fit nice inside rack

[10 TB (Total)] Works flawless with hikvision cameras pro results for small business
PoE works great

[5.67 lb] I bought this to replace my NAS so I could record 24/7 on a of my cameras with out purchasing additional licenses and taxing my NAS hardware to the point of not functioning. So far it has performed wonderfully. The first 24 hrs was a little underwhelming and I was worried I would regret the purchase, but once I got everything operating how I wanted it and got used to the interface and remote interface it had lived up to my expectations. Highly recommend this unit for hikvision cameras AND 3rd party cameras. Works great with wifi connected cams as well.

[Yes] I bought this to replace a Truvision 4-Channel NVR. I am definitely not a novice but it was easy for me to setup and plug n play with Hikvision cameras. This is a nice upgrade with a good price.

[Yes] 16ch POE NVR with a ton of features...what's not to like?! I replaced a nonbranded NVR that would not work with some newer 4k cameras that I bought. This NVR worked perfectly and since B&H is an AD for Hikvision, I know if I have an issue they can help me!

[5.67 lb] I purchased this NVR for a simple two camera security system on my home. I bought a separate hard drive, which gave me twice the recording capacity for the same price as one that came pre-installed. Installation was easy, thanks to videos on YouTube. It came with the necessary connectors to install the hard drive. I installed the NVR , along with my cable modern and wifi router, in a pantry and it works fine. It is plugged into a good quality surge protector. It make a bit more noise that I expected, but it is not bothersome. Hopefully it will provide years of service.

[10 TB (Total)] It is a bare bones, moved over a 6TB purple, unit formatted and initialized easily.  Had to get up and running quickly, First Hik product so had to install iVMS4200, and HikConnect on devices, at least 3 different username/password sets and not too clear on those descriptors. Used 3 IP POE hik cams, all plug and play. POE worked well.  Local monitor view and setup was excellent, wish there was better interface than a wired mouse, but at least I didnt have to repeat steps with that.  Did several reset, shutdown, and live disconnect and reconnection tests, unit rebooted fine. Good value for a DIY bundle.  Went with B&H to keep HIK usa distributor channel integrity for best support.
