    Best NVR you can buy right now, hands down.

    This security camera system is legit and the best part is there are no monthly subscriptions draining your wallet. You buy it, you set it up, and that is it. No recurring fees, no cloud storage charges, no nickel and diming you for features that should be included. Everything is stored locally on the NVR and you own your footage outright.The 4K quality is sharp and clear. I can actually see faces, license plates, and details that matter when you are reviewing footage. Cheaper cameras give you a blurry mess that is basically useless if you ever need to identify someone. This system captures rea

    I would give over 5 stars if I could

    I first bought the Eufy robot vacuum mop and OMG I love it works great user friendly and customer service was top notch I had a issue with it and only had to email them and they resolved the issue quickly and conveniently. Then my Reolink outdoor wired cameras went out after a year they just stopped working so I decided I was gonna replace them with the Eufy security S4 Max because of my love for my Eufy clean system. AND I AM SO HAPPY WITH THESE, The price was a little more than the Reolink system but it is 100% worth it these ones have basically multi cameras in one they track movement and h

    Very high-end professional system, priced for the home market !

    After extensive research and wanting to set up my first ever home security camera system, I found what I believe to be is the best one, which is this Eufy 4K NVR system. I bought this along with the additional two-pack of S4 Max cameras for a total of six cameras. I didn't want to have to change batteries or run electrical to each camera, so a PoE system totally fit my needs. Probably the hardest part of the entire set-up was running all the cables from all the corners of my house, through the attic, down the pass-through to the basement to my tech box room under my stairs. Luckily, I did all

    Buggy NVR, terrible AI support, great human support willing to make things right.

    It's defective. The unit appears to have some POE issues.First, let's talk about their customer support. My initial impressions are awful. They have opted to use AI to waste our time when we call. When it finally decides it can't help, it'll try and fail to transfer you to a person. Then it tells you to call back in a few hours. When I asked for a callback or to wait on hold, it told me those services weren't available. That's not true. If you get an AI, just keep calling back until you don't.Ok, as for the product, it's defective. I think there's some hardware issue with the POE. I bought the

    Perfect security cameras for the price

    Love this Eufy set-up. The set up was easy and the cameras are phenomenal. The app used to controll everything is easy to use unlike my previous system. I love having two separate cameras, one that detects and one that follows objects. The AI identification is nice and like anything new needs to be tweaked.

    Buyers beware!

    I wouldn’t recommend these camera or anything that is made by Eufy. I bought these cameras because the reviews were good like how I could get my whole property covered. Well I’ve had these cameras up for about 3 months now and 2 of them stop working. The ptz cameras stop working and just sake and I get no connection through the app. No big deal there under warranty so I’ll call eufy support. Well ever time I try calling there call volume is too big and unable to speak to a representative. Eufy did email about a warranty claim I sent them everything they ask me to do and still haven’t heard not

    Great Company, Great Product… Just Works 🙏

    I can’t say enough good things about this company and product. After years of research, I always landed back to Eufy. The product just works and the dual camera is amazing.One of my favorite features is that you can set a default view for the bottom camera so if the camera on the bottom ever moves because of activity somewhere else, once the activity is over, it will eventually return to its original position so because of that each camera really is essentially two of them. And the tracking feature with the bottom camera is unreal. Obviously there are no battery issues because it’s a wired sys

    Fantastic

    Being on my 5th security system because of better equipment upgrades, such as bnc to poe,1080p to 2k to 4k cameras, This is it. The AI is really really good, follows people, animals on all of my property. The color night vision is my best so far, although I have street and alley lights. The camera picture clarity is spectacular. Eufys setup took a day for me to find all the fine tuning I needed being not used to thier format. I know this a little pricey but the qualiy and coverage for 4 cameras is well worth it. My last system I had 6 cams and 2 ptz's, $1100 into it from 5 years ago. Eufy nvr
