remotely connect to your security system from your mobile with FLIR Cloud app

Remote mobile viewing with FLIR Cloud™

The NR8163 is compatible with our new hassle-free FLIR Cloud™ connection service. With FLIR Cloud™ connectivity, you can view your security system from virtually anywhere in the world using a smartphone, tablet, or computer. With iOS®, Android™ and PC options, your security system will always be at your fingertips. Simply download the free app, scan the NVR’s QR code, and start viewing the live feed (or recorded playback) of all of your cameras. In-app options such as push notifications and instant email alerts for motion-triggered events will keep you up-to-date to any movement caught by your IP security cameras.

Works With

PoE (Power over Ethernet technology) installation for IP cameras

IP cameras with PoE cabling for flexible installation

he NR8163 NVR uses power-over-ethernet (PoE) technology - an all-in-one solution that cuts cost and installation time. Simply connect your IP cameras to one of the NVRs 16 integrated PoE ports with a single cable that provides both power and video transmission. This allows you to position your IP cameras where you need them most without the need to have a power outlet nearby. An NVR like this can also incorporate a PoE switch. This not only allows you to decrease the amount of cabling needed for larger installations, it will also open the door to add more cameras to your security system.

High-capacity, high-efficiency reliable hard drive

Heavy-duty high-efficiency HDD

The 3TB security certified hard drive within the NR8163 can safely store weeks (or even months) of recorded security footage. Engineered for the constant workload required by security monitoring, this HDD can continue to record even while you watch recorded footage. Pre-schedule recording times or adjust the NVR to record at a lower resolution to extend available hard drive space. You can also save storage space by recording only when movement is detected.

Purchased this system after 2-3 months of intense internet research & reviews. Needed a 12 color camera HD IP system for a medical office and after a call to Lorex, the rep suggested the exact equipment at the best possible price point. The system arrived as promised, well packaged, and even included a complete extra set of Ethernet cables! The system integrated flawlessly into out office IT system and set up was easy, as its virtually plug-n-play. The 4mp camera provides an excellent 90 degree view with color night vision. Downloaded the FLIR Cloud IPhone App despite mediocre reviews and it has worked well. This is a good system for the money and so far has worked very well. Will be purchasing a system for home use soon.

Working with Lorex support has been quite an experience.

I ordered a LNR168 kit which was supposed to include the following:
(1) NR8163 sixteen channel NVR.
(8) LNB3321B Color Night Vision 150 foot range cameras.

What I received after a 7 day wait from order time for shipment and then another 5 days for shipping was the following:

(1) NR8163 sixteen channel NVR as ordered.
(8) LNB3143B IR cameras with 130 foot range.

A web chat with Lorex support tells me that their web site was wrong and what I got was correct.
This is an interesting way to do business.

Then after plugging in and turning on the NR8163 NVR within 30 minutes it started to develop a very loud whine.
In fact I measured the sound level with a meter and it measured 55 dBA at one foot away. This is about 4 times louder than
my tower computer measured. At this sound level it is not useable in my home and I had to turn the unit off.

After reading other reviews on the NR8163 NVR any many other Lorex NVR's Loud noise appears to be a common issue.

I started a chat session to find out that I needed to call two different groups at Lorex. Sales and Product support.

I decided to call sales to work on the wrong cameras being sent and after an hour of waiting I got to talk to a live person. I was told to take multiple clear pictures of the cameras received and send them to an email address. Now that that's done I get to wait a few more days for a response I guess.

I have not heard anything on my 2nd ticket regarding the defective power supply as it's only been 4 working days so far.

I expect that based on my prior experience with tickets it will take lorex a minimum of 5 days to respond unless I want to wait on the phone for an hour again to talk to a live person.

Perhaps I can write a real review of the product if I ever get it working.

The bottom line is "DO YOU FEEL LUCKY". If you do then order something from Lorex and good luck.

This DVR is absolutely AMAZING! I upgraded to the color night vision domes for all of my cameras. The night vision is unbelievable. The SUPER sharp 2k / 4MP resolution is something unheard of in the home/business security industry for this price! Absolutely awesome! The iPhone app is very good as well. Super easy playback and live view. The MAC Book app is also amazing! I'm telling you!!! The picture quality is friggin AWESOME!

Bought this security system after doing some research on the internet. Was a little nervous spending the money on the Lorex NR816. It did not take long to get it here and I was impressed with the Quality of the product. It took very little to hook up, and everything worked right away. We cut down the cables to the length we needed in order to keep the server room as neat as we could. I did have some problems with downloading the program on my computer, however it was a issue on our end and the service we received from Lorex was exceptional. All the complaints that I had read about on reviews did not happen at all to us. Very happy with the product, its operation, technical service and quality.

This is our 6th Lorex surveillance system purchase, and so far this is the best one yet! The NVR is super fast to respond, has extra room for another hard drive, and the quality of the cameras is great! The IP camera systems are definitely the way to go...don't bother with the analog systems...go straight to digital and be done with it. Thanks Lorex!

Has been up and running for 2 weeks without any issues. I found most of the interfaces to be fairly intuitive, and the hardest part about setting up the cameras was getting the wires to their locations. Otherwise, it was pretty much plug-and-play. It found the cameras, and automatically began recording.

I frequently access the NVR over our LAN (so I can watch the cameras), and the only browser that seems to work with the Lorex extensions is Internet Explorer (Google Chrome and Microsoft Edge kept giving a prompt to install them). The browser software is a little more limited than what you get on the NVR, and crashes on occasion, but it's workable.

As other reviewers have stated, the hard drive does have a high-pitched whine, so it's probably not something you want in the same room with you. I have it about 20' away in a storage room, and can only hear it with the door open. It's actually louder than any of the fans or drives on our servers. As long as this doesn't affect performance, I'm okay with it, but there is room for improvement.

On the plus side, I really love how the timelines show where motion was detected, and how you can select an area to watch only when there is motion in that area. (However, it would be nice if it searched multiple days, so I wouldn't have to redefine the area for each day.)

Unit has been running for 24 hours and the hard drive has a high pitch whine. Nothing like that from my laptop or 2 other computers. Pretty annoying. I can't move the unit away from my office as all the cables run there! I read several other reviews which warned about the high pitch whine. I've got a 50% hearing loss and it is still annoying to me.

Update: Customer service on this issue was great. They sent me a new hard drive box quickly. The hard drive still makes it a loud whirring sound. I have two computers and one laptop and 4 monitors and none of them make any sound. At least it no longer makes the high pitch whine but I will still have to make a box to stop the whiring sound.

WHile it took some time for the package to arrive (2 weeks), upon installation, everything works great. Flir Cloud was effortless and all the cameras worked good. Excellent video quality (I used to own a Lorex CIF system). HD is a much better video quality system.
