The only issue is the very noisy cooling fan inside the hard drive unit

The only negative is the fan is quite noisy

If you try to upload the same firmare a camera or the DVR already has, instead of saying something clear, it will just say that the update failed, so you don't know what happened.- Fan is loud, so yes, it has to go into a closet

Fan on NVR is pretty loud due to high fan speed.

I have to admit: this system has its flaws (mainly the loud fan and the highly sensitive motion detection) but not enough not to get a 4.5 star review from me

But after powering up the unit the fan is SO LOUD that I changed my plans and stored the unit in a closet

One star knocked for buggy login process, on-screen keyboard unreliability, and noisy fan

The fan is noticeably loud.

The fan on the NVR sounds like a jet plane, to make the microphone work took alot of additional work, should have been easier, one of my cameras had an adjust screw stripped so we will see how customer service

The NVR fan can be heard but it’s not as loud as the Amcrest DVR fan.

PRO: Good image quality, cameras include audio, out of box ready to go, easy cable managementCON: Loud fan on NVR, Setup did not "auto" find my NVR on the network (Easy enough to input the ID from the app)

I wondered if the small enclosure might mean it had an undersized fan that would make it run hot and

The fan on the unit is a little noisy if you have this in a quiet room, but it’s tolerable

All of the sudden one of the cameras doesn't work same as beforeOnly three stars because of the annoying fan.

With a silent fan it would be perfect

I gave it 4 out of 5 due to the noise level of the cooling fan on the CPU none of the other reviewers mentioned

It's unfortunate that the small fan is pretty loud, so I don't recommend putting this NVR near where you sleep===SOFTWARE

The fan in the NVR is very loud.

Fan is really loud

One last comment, the cooling fan is LOUD

I gave it 4 stars because of the noisy fan in the NVR.1 year update: It has been 1 year since the installation (running 24/7

The main one is that the fan on the recorder is loud, I opened the case thinking that I could just switch out the fan for another brand small case fan, but unfortunately it is soldered onto the main board

One last comment, the cooling fan is LOUD

I upgraded the cooling fan, it did reduced the noise a little but not much

My install is with my main home theater equipment and the cooling fan for the camera CPU is ever present.

This system is easy to install and has a good amount of features, my biggest complain would be the fan as most mention here, I tried to replace the default fan with another one I purchased from Amazon but its still loud

Everything works as it should, and they have great documentation on the included CD, including a well written user manual, quick start guide, and software for your desktop computer and more

I have to say I'm honestly surprised by Reolink correcting this issue as fast as they did

(Unconfirmed as of the date of this update).

Picture quality is pretty decent, but not as sharp as I had thought especially even when zooming in a static object no more than 15-20 feet

difficultI would definitely recommend to a friend without hesitation as long as they know about the issues above
