ZOSI2K WiFi 6 Security Camera System,4pcs 3MP Plug-in Wi-Fi Cameras Indoor Outdoor,Spotlight Color Night Vision,AI Person Detection,2-Way Audio,4K 8MP 8CH NVR with 1TB HDD for Home 24/7 Recording

I bought the 4 camera version about 5 months ago. I wish now, I had went with the 8 camera version. And as you will read, their customer support is top notch which is one of the reasons I am now reviewing the unit... one of the camera I thought had failed but as their support was able to help with, in fact it did not and they easily helped get it back working again. I explain more a bit down this review.*NOTE for those wondering if you can hook the NVR wireless to your router, the answer is a yes and no. I had to place the NVR on the other end of the house from the router but did not want to run wiring... so I found a way to do it using wireless extenders which I will explain at the bottom of this review.Regardless, the quality of the camera's is outstanding especially at night. I have attached a video link of the camera catching a bear at dusk coming toward the house as the cameras switched into night vision mode.The reason I am writing the review now after 5 months however, is due to the customer support I got. One of the camera's suddenly failed... or so I thought. In reality, it turned out that I had to simply reset the addressing hardware ID code for that camera. It failed during a storm and my thought is a lightning strike may have just scrambled the brains a bit. BUT it was not until I contacted the company about a replacement camera that I learned the camera was probably fine.. They instructed me how to reset it and sure enough, it is back working perfectly. They were fast, courteous and knowledgeable. So I will definitely recommend this company and brand for those looking for a system.Finally, hooking this to your router. Sadly, the NVR does not allow you to directly do a wifi connection to your router. While the cameras all connect wireless to the NVR, the NVR itself has to be wired somehow to the router. In my case however, that would have meant running line the entire length of my house. Not something I wanted to do.So I thought about it a bit and then came up with a simple solution.. I bought one of those 'wireless extenders' you can simply plug into an outlet to extend wireless around your home. What many don't realize, is those extenders have BUILT IN network plugs! So while they are used to actually extend your wireless range, they can ALSO be used to plug in a WIRED DEVICE to give IT access to your router!So all I did was buy one of those, setup the extender to extend my wifi in my home, run a network cable from the NVR to the plug in the wifi extender and walla, my NVR is now connected to the router wirelessly because it is directly plugged into the extender via network cable.And it works perfectly.. In fact, I wanted to place one of my camera quite a distance from the house... but wireless range, especially for a video signal, is not very far. So what did I do? I bought a SECOND wireless extender, plugged that one into my workshop and then plugged camera 4 into the wireless extender via network cable and it now can be monitored through that connected wireless extender as well! Wireless extenders have a lot more power and range than the camera on its own. Probably double from my testing so this solution allowed me to place a camera where normally I would not be able to reach wirelessly on its own.As I started this review with, my only regret with this purchase... I should have bought the 8 camera version.. I really need it now as we moved into a larger home and a lot of land.. Wish the company would trade me up to the 8 camera from this 4 camera! ;-)

Installed and have been using this system for a month and so far I absolutely love it. I love the feeling of added security/safety it provides.Setup was a breeze. Mounting was easy. The biggest pain was running the cords to a power source. Even with that, I had the system fully installed and running in less than six hours. The cameras were pre-linked to the receiver/DVR and while it's a bit of a pain to navigate the system with the provided mouse, so far it all works fine. It's been through rain, high winds, and the beginning of cold winter temperatures, and so far so good. It hasn't dropped connection yet.All four cameras are on the FAR opposite side of the router in my ranch-style home, so I added a Wi-Fi range extender to the room nearest the camera placements and all four have a good, strong signal. The images, including night vision are great. They far exceed what I would expect for the price paid.As far as the remote app viewing, EroCam is the one I use most often. IP Pro is another one I have configured, but EroCam is my go-to favorite. For setup you'll need to know the Device ID, which you can find in your system settings (on screen), and password (defaulted as blank but you supply your own during setup of the system). The biggest advice I can give for the remote app is to turn off your Wi-Fi when using it away from home. More often than not if you're on a guest network somewhere, they have security settings in place that won't allow your camera views to load. As long as I'm streaming through my cell network, I rarely have issues with the views loading. The app works fine when connected to my home Wi-Fi.I actually installed the entire system without ever looking at the manual. Not ideal, or recommended, I'm sure...ahem. BUT, it really is that easy. The cameras coming pre-configured from the factory is fantastic. I did set everything up inside prior to doing the install. This way I knew everything was connected and functioning as expected prior to beginning the mounting and physical install.I will come back and update my review as time goes on or if anything changes and I have to reach out for service, etc. But as of right now, I couldn't be happier with my purchase!
