Great POE 4K system - Excellent product and service
So, firstly I don't usually write reviews (not proud of that!). I did loads of research for types of camera, system etc. and arrived at this one. The kit seems robust, well made and the output quality (4K) is extremely impressive. The software (Windows client and Android app in my case) installed easily, and works fine. It's free for life. After 9 months of use, and the mother of storms one of the cameras became misty. I notified them, and immediately they contacted Amazon and shipped me a new camera within around 3 days. Incredible service. I will protect the new camera a little better, but perhaps there was a faulty seal etc.. The others are fine but they are located under the soffits. The documentation is not great, but the email support is virtually instant. The website is also very good for set up etc.. Slight downside is no fast forward on playback, but you can skip through selecting different times etc.. I guess the whole purpose is that if you had an incident, you could locate evidence (as well as being preventive of course). I upgraded my hard drive easily to 4TB (because I record in 4K) by purchasing a 3rd party hard drive (Toshiba). The new one was slightly noisier, so I relocated the NVR to the attic from a bedroom (the original was quiet). So, think long and hard where you locate stuff! I also easily set up record to a FTP server. The motion control is over sensitive on all systems I believe, hence 3 stars. My system records everything, and when playing back you can see the motion markers which is handy. Overall excellent system, service and value for money.

Issues resolved swiftly
System is now all installed to IP rated mounted back boxes, issue with waterproof plugs resolved with a partial refund, which covered the cost of the mounting back boxes, thanks to Scarlett in CS. System is easy to use, was easy to setup, and tweak over a couple of days so detection is not false alarming. Privacy areas are easy to do, so you can mask areas in neighbouring propertys if required. 3 of my 4 cameras are set to alarm on detection, but also record 24/7, 1 camera is set to alarm only inside the property, in a room nobody should really be entering, also has cctv nvr located in here. All in all an excellent system, great video quality, I can access from PC, TV and mobile phone, and receive alarm notifications by email. This is my updated review, after a small issue as mentioned above.

Great picture quality. Four camera system with capacity for eight cameras.
Bought this to replace an old Swann 4 camera system. I bought an extra camera making 5 cameras, It was easy enough to set up which is as well because the instructions leave a lot to be desired, biggest job is running the wires around the house. As it was a replacement, we used the same holes making it a bit easier. The kit comes with four additional cable plugs, I used these to shorten some of the cables. The "fitted" plugs don't fit into the weatherproof plug covers so I trimmed off the the ribs from the back of the plugs so they fit. Picture quality during the day is great, as it should be with 8mp cameras. The cameras have a 4X digital zoom but you can't zoom in on a recorded picture. Unlikely you would be zooming in when the system is recording but you would want to be able to zoom in on the recorded picture but can't. Night pictures are ok but you would be hard pressed to get a positive I/D on a thief. I found that the cameras are a narrower field of view than the old ones so you may need more cameras. All in all, it is a very good system with few drawbacks.

Excellent system at an affordable price.
Works really well, truly plug’n’play right out of the box. Fully recommended. Have used other more expensive, commercial systems elsewhere and this compares pretty well for domestic use. Pros • Images are excellent quality and very clear. The Client software means you can manage the device / images from a PC or Mac with ease. • Connections are simple and well documented in the manual. • Reolink support site is good and appears to be kept up to date and with upgrade firmware. • Reolink Android app is very useful when pointing the camera. You can see the live view while adjusting from the top of the ladder ! • For those new to CCTV, using Motion Detection is also worth considering and means that only events likely to be “significant” are recorded. It works well on this device and means that playback jumps from event to event without having to trawl through (possibly) hours of inactivity. Manual is helpful, but getting the Motion settings right can be fiddly (true for any system). Cons • Consider where to mount the cameras and run the cable back to the recorder (approx 60ft cable for each camera). A small issue is the connection to camera when placed outside. The “waterproof” connection cover provided won’t work as supplied and one solution is to mount separate plastic junction boxes close by and place the connection inside. (such as Amazon "Outdoor Junction Box 91mm x 47mm with Connector Blocks and Soft Knock-Outs Grey Waterproof IP66") • Reolink kit appears not to be compatible with other makes. This may be significant if your system will need upgrade in future. However, at this price it’s a risk worth taking unless you are a growing enterprise. Overall a very good purchase and well suited for domestic use.

Does what it say on the box
Looked at various cctv products, helped putting up another popular system for my sister, didn't like that at all. Settled on reolink. Been up about 2weeks now, it has already captured what was required, thanks to the 8mp camera I was able to zoom in to the very edge of the captured footage and still have some clarity, this was in the dark with ir turned off. Quality of cameras is good, I had no issues with any of the supplied cables, I read one review saying they were poor and you couldn't put them through walls or tight spaces, these are internal network cables, I taped the ends up to protect the plugs and managed to run them all no problem, all worked first time. The nvr was easy to set up, I didn't need to refer to the instructions it's all straight forward, only stupid thing I did was contact support about the use of a USB hub as I had read another review saying it only had 1 USB, it has 2, one on the front 1 on the rear, that was my fault for not looking at the instructions, crystal from support emailed the next morning with a nice pic of the locations of USB ports, so I now know support is there if needed. Nvr is very quiet in operation, app works fine, Windows client is great and can access everything needed. I would buy this again, very pleased with it.

Great picture quality - poor playback features
Impressive live images from this kit, both day and night. Easy to setup and good configuration options. However, for me, the major issue is with the client playback options. For some reason you can only play back at normal speed or slower(!). I have always found a "fast forward" feature essential for reviewing recordings when trying to find a particular event, but this is not available on the client applications for this device (PC and phone/tablet). If you use continuous recording then this kit will not be practical to use. Even if you can narrow down a time of interest you are still going to have to sit and watch the recording in real time until you find what you need. In my setup I have enabled motion detection. This does work well, however my house is on a reasonably busy road and triggers with every car that passes (unable to mask fully). Reviewing 100+ events in a day at real time is not practical - so catching that delivery driver or cold caller is a real pain to do. You can download videos and view using another application if you really wish - but this should be a feature of the client application. My much older and cheaper system can do this with x2, x4, x8 playback speeds. Presumed this would be a standard feature and requirement of all CCTV systems. Also only seem to be able to have one client connected at a time - this might be something that can be changed that I have not found yet, probably not a deal breaker but again my older system can have a least 2 clients at the same time. Going to persevere for another couple of days to see if I can come to terms with this - otherwise it's going back as not fit for purpose. Update: decided not to keep as play back to cumbersome. Having several days of sunny/cloudy conditions ended up with hundreds of alerts from two outdoor camera to search to find genuine activity. Changing thresholds on motion detection to prevent sun triggering also prevented detecting car moving on drive so not really a benefit. I guessing if you use this for indoors only then it's a great bit of kit. Otherwise not very practical for outdoor use.

A bit disappointed.
I've had this product for a few weeks now having installed 5 cameras around my house and configured the NVR I feel i'm in a good place to provide an honest review. THE GOOD. Image quality on the B800 camera's is great. Perfect during daylight and pretty good at night, but you only get good night vision if the IR lighting on the camera is sufficient to illuminate the area being monitored. If not you will have to buy additional IR lights. Out of the 5 cameras I setup, only the rear garden needed additional IR lighting. The NVR is well made, but the instructions on how to set it up lack information about what many of the settings are for, it just states how to adjust them. I guess what I am saying is there are many options to configure the unit but no guidance. THE BAD Reliability has not been great thus far. Motion detection is hit and miss, so can't rely on it to activate all the time so will not use. Have had to reboot the NVR a couple of times as the cameras go offline. I use either a PC or iPad APP to control the cameras' Nether are very good. The version running on my mac frequently crashes and is unable to replay recordings. The iPad version is a bit quirky, but I can get used to that. The live streaming can often hang them come back. I assumed this might be a bandwidth issue, but ruled this out after experimenting. Motion detection recordings hang part during replay. I just watched my wife return home from the gym and replayed her entering the drive, parking and as she exits the car the video freezes. I've experienced this a number of times hence another reason not to use motion detection. So in summary, well made, great picture, unreliable motion detection and video playback / recordings.

An excellent CCTV with even more excellent customer support
Good performance and really EXCELLENT support if you ask a question. They actually answer what you ask, and provide to-the-point, accurate information. So exceptional these days and can make or break how well you can make use of a system. The only downside is that the unit cannot be bought with a larger HDD. It can support up to 8TB internally, but comes with just 2TB. The unit can also support an additional 8TB externally (no second internal HDD possible), but the eSATA expansion port is of limited use as eSATA enclosures for a second disk now seems impossible to come by, unless you by a multi-disk semi-professional mini-rack
