NVR Security system S4 Max. Very easy to install and set up. Excellent picture quality both day & night. AI and dynamic tracking is phenomenal for a system at this price point. Had the system nearly 4 weeks and working flawlessly.
I was a little unsure whether I should give the Eufy system 4 stars or 5, but in the end I picked 5. Its really a very good system. The best feature is that it has cameras with two separate sets of lenses, one for wide angle that cover the whole area at once and the other to zoom in on things that are caught. The two work together to catch everything that happens and create a log.The system also has quite good face recognition and inter-cameera tracking so that an easily reviewed event log tells you quickly about everyone who has been around. You can save friendly faces in the system so that it can weed ouyt strangers.The other nice thing is that it logs everything locally on a server, and also backs it up in the cloud. The best of both worlds. The cloud backup is not overpriced, and also optional. Great.The downside with this system was that I had to wire everything up with ethernet cable, which was fine of course because I wanted powered cameras. I can add wireless ones as well if I want. The only issue with that was that it wouldn't let me connect the ethernet switch back to the server wirelessly. I would have liked to have had that feature, but its a minor point. The system as a whole is good and the wired cameras work well.
We purchased the system to secure the perimeter of our property and much better than what we expected. Easy to install and everything you need in the box. Would recommend purchasing.
The Eufy S4 Max Security System has completely exceeded my expectations. Setup was quick and effortless, and the app makes monitoring everything incredibly convenient. The video quality is crystal clear, even at night, and the motion detection is spot-on without being overly sensitive. I love that there are no hidden fees or monthly subscriptions — it’s a one-time investment that provides real peace of mind. The build quality feels premium, and the system integrates seamlessly into my smart home setup. Overall, it’s reliable, user-friendly, and delivers outstanding value. Highly recommended!
I've been waiting for a NVR solution for some time, and decided to go with Eufy, due to the AI capabilities and the dual camera approach on each Camera.I've had this in place for a few weeks now and found that this ticks most of the boxes I was looking for.Strengths:Audio control detection and two way conversation is goodNight Vision Is strongPeople detection and Tracking is GoodFace recognition is good (assuming you keep on top of it and keep training)IssuesThe cameras are not IP cameras, so cannot today just plug in to your network - they must be connected to the NVR - that can we over a dedicated PoE SwitchSome detections are questionable - but can be trained outOverall. Very happy and I recommend this solution.
Great camera top quality
This security system is next level and so easy to install! The images and video are crystal clear and for the money I dont think you van get any better. Highly recommended to anyone who os looking to upgrade their cctv .
I couldn’t be happier with the Eufy NVR Security System S4 Max. From the moment I opened the box, setup was unbelievably simple – literally plug and play. The entire installation process was effortless, and the app setup took me fewer than ten taps!
Everything just works seamlessly. The picture quality is excellent, the notifications are quick and accurate, and the whole system feels reliable and well thought out. I’ve tried other security setups before, but nothing has been this smooth or user-friendly.
It’s when they’re installed and you’re on the app when you can really see the power these little cameras have.
If you want (you do!) a system that just works out of the box without frustration, this is it.
You don’t need to install new outside lights because these can light up a runway! (Don’t worry, they’re adjustable, too)
Highly recommended! ⭐️⭐️⭐️⭐️⭐️
There are many detailed reviews on YouTube.
What a great device!!!! Get camera to add to my NVR system. Completes the set up and easy to install...
This is the future of CCTV. Top quality NVR. Not your usual plastic box but metal and looks fantastic in silver. Putting up the cameras is straight forward. Had it 2 days now and it works better than my Swann 12K system which was double the price. I used to have 8 Cameras with Swann now with this unit I only need 4 as its dual lens and can be focused on 2 different areas at once. Only a few issues that I thought their testers should have found. Fan is noisey i have the NVR in bedroom but only comes on for a few seconds. App sometimes doesn't show cameras but a simple close app and reopen sorts the issue. When using selecting HDMI channel for camera you get a loading screen for 2 seconds. Not sure why that is but I can live with that. Ai tracking is spot on. Not missed a thing. Picture is the best I've seen even at night. This is the future of CCTV NOW.
