REOLINK4K Security Camera System - H.265 4pcs PoE Security Cameras Wired with Person Vehicle Detection, 8MP/4K 8CH NVR with 2TB HDD for 24-7 Recording, RLK8-800B4

These cameras are POE and easy to get setup with the NVR. Connecting the NVR to the PC and Phone applications was super easy. The only hard part about this is running all the ethernet cables to the cameras locations. We ran the cables through the attic to all camera locations and installed a 6 port ethernet wall plate to connect them all behind the wall. Then I used patch cables to go from the wall to the NVR. Cameras were installed under eaves with a small waterproof box next to each camera location to hide the wires and also to keep them protected from the elements. All in all it took about a month for me to get everything ran and installed but that was working on them when I had free time. If there is interest I will post pictures of how the cameras are installed and the wall plate. All the effort was worth it for me to not have to worry about wifi signal strength or having to change batteries or charge cameras.Camera picture quality is great when completely zoomed out. As with any camera that relies totally on a digital zoom you lose picture quality quickly when you try to zoom in on something. I do suggest you mess around with the Image Settings for the cameras for when they are recording in night mode. I had one camera especially that had pitch black background after about 30 ft from the camera. I upped the brightness on the camera and can now clearly see what was in that area.I was able to add 2 more Reolink cameras to this system with no issues. I added two of the 5 MP dome cameras to go over the front and back doors or the house.Something that was important to me was replacing the corded mouse that the system comes with with a wireless mouse. After trying out a few different mice the one that worked for me was the Logitech M310. It lags a bit sometimes but it is better than having to be right by the NVR to use it.

This system is very good for its price category.These new "B800" true 4K UHD cameras are the real deal.As many previous comments and reviews note, these newest true-4K cameras are running behind on ReoLink's "software" support of their tremendously capable hardware.These cameras were "originally" intended to support the newer, and much more efficient, "H.265" video compression protocol.This would have offered almost 50% better compression-factor (read half-the-file-sizes) for the same video content/quality.For whatever "licensing" or "technical reason, ReoLink had to drop the ball on H.265 compression support. Very bad move on their part in my opinion.In addition, these cameras MUST be used only with the "8" channel version of ReoLink's NVR RLN8-410.The 16 channel ReoLink NVR is not capable of supporting 16 4K cameras (no doubt because of both 100 Mbps Ethernet bandwidth at full 4K frame rates and video bit-rates).Also as mentioned there is no ONVIF support for these "B800" model 4K cameras.Now the shortcomings of ReoLink's support of this great video hardware:1) No H.265 compression algorithms available (meaning HUGE H.264 file sizes). Even at a reduction to 12 fps and setting the maximum bit-rate to 1024 bps, one is looking at about 900 MB-per-30 minutes-per-4K-camera.2) The following features are NO LONGER AVAILABLE within the Windows (v.7.2.33) or Mac client version of theReoLink software for this NVR/Camera combination:a) No longer any "Fast-Forward" capability when the "target" is the NVR (as opposed to any of their otherindividual cameras).b) No longer any "Fluent"(highly compressed, low-frame-rate, and small image pixel count) stream available for download. This is a HUGE problem/oversight at these large 4K H.264 file sizes when reviewing stored video content from remote sites having limited UPSTREAM bandwidth; which is a very common requirement.c) The Windows client (v.7.2.33) easily "locks up" and must be restarted. This happens when one clicks quicklyamong the available software features (i.e. skipping to new timeline points, switching displayed cameras,having 'too many cameras' visible on the screen at once etc.,)Quitting and restarting the Windows "Client" software always "fixes" the issue, so I'm not sure that this is caused bythe software/hardware of the NVR, or the Windows "ReoLink client" software....The same lockup issue occurs for both the 32-bit and 64-bit version of the ReoLink Windows client.d) Most often one, or more, cameras do not immediately display their "live" video content. Sometimes aparticular camera NEVER displays in the "client" software until the client is again RESTARTED.3) There is no apparent way to "upgrade" the firmware of these new "B800" true 4K UHD cameras like there is for ALLof the other ReoLink camera hardware.4) There is NO embedded "web-server" software available for these new "B800"cameras.This is most likely related to why they MUST be used with the 8-channel RLN8-410 NVR and cannot be used stand-alone" as the other ReoLink cameras.5) While the inclusion of a 2 TB hard drive is commendable, even with only four 4K cameras connected to the NVR,and at even very modest bit-rates [1024kbps] and frame-rates [10fps], this would allow for only about 5 calendardays of "24x7" historical video content review. This is again, and in large part, due to the missing support for theH.265 compression algorithm.6) While not the fault of ReoLink, even true 4K cameras have a hard time reading (at least foreign) license plates at any"normal" distances. The genuine "4K" picture truly is impressive in all other regards. Even the "5MP, 4X optically-zoomable", ReoLink cameras (or any other brand) struggles with this particular task.7) The boys at the ReoLink software labs need to get much further, and much more frequently, "with the featuresprogramming" for the Windows/Mac client. I can achieve a better "remote viewing experience" (for both LIVE andPLAYBACK) simply using the ReoLink client software running "remotely" and then connecting to a local Windows PCusing Microsoft Windows 10 "Remote Desktop Client".As a software/electrical engineer myself, and given the fact that the ReoLink engineers own their entire video camera's tech-stack, as well as the NVR and camera's "firmware", this is not impressive.Even with all of the "bugs" above having been formally reported to, and then 'acknowledged' by ReoLink tech support, using the proper "customer support methods", the current v.7.2.2.33 software has not been "updated" in well over 3-months now.8) There is no way to control the nighttime IR illumination of these B800 cameras (the option is available "nowhere", as it "is" for all of the other ReoLink cameras)Niceties:1) NVR storage is very easily expandable using both any standard SATA drive [internal], or eSATA (using externally supplied 12VDC power) and an eSATA data cable.2) Unit is "tiny" (stores easily almost anywhere).3) Camera PoE is available at all 8 Ethernet ports.4) Video "clip" download feature works very nicely (but again, no longer supports downloading the much morecompact "Fluent" stream, as do all of the other ReoLink cameras.)5) Cameras are extremely well built for this price point.6) The Android and iOS versions of the ReoLink client are extremely usable and very functional, given enough internetbandwidth being available.7) Very impressive $price$/quality ratio.8) The nighttime "infrared LEDs" are actually quite usable for scene illumination when not enough natural light is present.This truly is a great system!It could, however, be even better if they work out some of the "kinks".

Great NVR, very sturdy and clarity video.

Not a bad system for the money. I contacted presales to see if it would function as a standalone with no WIFI or internet and it does. Easy to set up. Playback could be easier to search with. Seems well built, however the cable sent was a nice accessory, but I did not use because it was cheap in quality and was not easy to un-not and pull. I replaced with CAT6 enhanced plenum rated cable, and terminated with quality ends, as what's typically used in commercial buildings and cameras. Documentation could be better. Video quality was okay, but the system would lock up sometimes when I was making resolution changes. Formatting and managing the drive was easy. And downloading clips to a flash drive worked okay. This system is being used as standalone in an outbuilding with no internet, so software updates and certain functions and phone app will not be available for this installation. It can be connected to the internet if it became available there.

simple and works
