REOLINK 4K Security Camera System, 4pcs Outdoor 4K/8MP Plug-in WiFi 6 Cameras, Full Metal Material, Color Night Vision, Person/Vehicle/Animal Detection, 16CH WiFi NVR with 2TB HDD, RLK12-800WB4

Overall, I am very happy with this NVR system. I used it to replace an old wired DVR system I used for over 10yr. It took me a while to get the wifi working consistently. Since old system was wired, this was a real challenge. All of my cams are outside and some are a distance from the house (up to 180ft away). I have an Asus mesh router but connection was inconsistent or nonexistent for cameras away from house. I had to purchase 3-TPLink outdoor access points (EAP650-can setup hardwired or wifi), a TPLink controller (OC200) and POE switch (TL-SG1005P) – quite a learning curve with all the TPLink components but got it working and it is great. TPLink has great documentation and lots of youtube videos,etc. The person/vehicle/animal detection works well and works at a good distance (further than Eufy cams which I also tried). There are occasional false alarms but nothing significant. Only problem I encountered was with 2 cams that would stop/start recording randomly. Reported to Reolink support but they had no info on problem. After much experimenting, I found it was with outdoor cameras with a lot of greenery – something about the intensity of the color(?). I reduced the contract, brightness & saturation for the cameras and now works fine.In addition to the 4 cameras it comes with, I added 4 more Reolink cams – including one zoom and one 180 degree camera – very impressed with both. I purchased a 12TB hard drive which I will install soon.The Windows software works well as does Android software. Takes a while to learn each but that is expected.All cams are connected via wifi and record continuous at 4k. My current laptop does not display 4k so next purchase will be new laptop capable of 4k.I’ve had this system for a couple months and feel confident I will be able to depend on it as I did with old wired system and it is REALLY nice not to run wires to each camera. I did have to buy a number of electric extension cords for the Reolink cameras but was able to place them where they are discrete and not in the way of foot traffic,etc. Should work better than old wired system with thin wires that were occasionally chewed on by animals, even when buried.
