Features
- Revolutionary Triple-Lens Bullet-PTZ Camera: A single groundbreaking device that replaces and outperforms separate bullet and PTZ cameras. The upper 4K bullet lens delivers a 130 fixed wide view, while the lower 2K dual-lens PTZ offers 360 smart tracking and zoom.
- Bullet-to-PTZ Tracking and Auto-Framing: Once the bullet cam detects a subject, the PTZ camera instantly locks on, tracks, and zooms in to capture details up to 164 ft away. When more subjects enter the frame, it automatically zooms out to ensure they all stay visible.
- Powerful Solar-Charging with SolarPlus: Stay charged year-round with a 5.5W ultra-large solar panel and SolarPlus 2.0. Just 1 hour of direct sunlight a day keeps the camera running, and the detachable design makes setup easy and flexible.
- Better with HomeBase S380: Unlock BionicMind AI to differentiate family from strangers. With 16 GB built-in storage, expandable up to 16 TB, rest easy knowing your videos are stored securely. Use the latest eufy app and update HomeBase S380 to V3.7.2.8+ to enable 24/7 recording and Snapshots. Other HomeBases (S280/Mini/Professional) and eufy NVR are not supported.
- Precise Detection, Powerful Deterrence: Radar and PIR sensors deliver precise motion alerts with fewer false alarms. When a threat is detected within your set zone or schedule, red and blue warning lights and a 105 dB siren activate to deter intruders.

The media could not be loaded. 2/22/26 It was definitely my router causing the issue! If you live in a wifi congested area i.e. apartments or tightly packed houses or if you're just experiencing connection issues I can say it is likely your router. I had the Gryphon routers and upgraded to the newest Gryphon AX router and it solved my connection issues with the Eufy cameras. They now connect fast and stay online. I also get the notifications much faster which is good for my isolated property. Please read the rest of this review to see my struggles. It's not the cameras it's your WiFi! 2/18/26 Okay, I first need to say these cameras do work and work really well. However, if you have a lot of IoT devices and or live around a lot of others broadcasting 2.4 Ghz channels then you may experience issues. I personally have a large amount of IoT devices broadcasting on the 2.4 Ghz channel and causing interference with the cameras. When the signal is good the cameras are fast to connect but other than that they are intermittent. This isn't an issue with Eufy though and the only real way to fix the issue is to remove devices or change channels on the wifi router. I tried different channels but that didn't help. The IoT devices followed and swamped the signal again. The Eufy appears to broadcast on channel 1 but I've noticed it change itself to channel 3 also. This isn't adjustable on the settings which is a bummer. You can download a free wifi analyzer on your phone and see the networks and congestion of any. I should have done this in advance as I would have purchased the wired EufyCam system using PoE. I have another camera system that is PoE cameras and it's rock solid. Again, my issues aren't with Eufy, it's with my network. 2/10/26 I am more impressed with their tech support, which I should have known would be great since their owned by Anker. (I love Anker battery backups) I had previously written my experience below but after some modifications and help with their support the system is great! I added the Eufy Smart Display and that was the game changer! It alerts me while I'm sitting on the couch and instantly shows me the display. The app I still think could use some improvements but I've learned more about the settings and stuff so that's helped a lot. I am writing this in my own opinion and not by or for Anker and or Eufy. That being said Eufy did offer me two free batteries for the cameras or a reimbursement of the product via email which was nice. I declined as I didn't feel that was right since I hadn't fully learned the system and I now love it. Take your time and definitely reach out to their support team if you need help! I have four other camera systems around my house and property with a total of about 20 cameras. (Backed up by Anker) That being said I am really good with camera apps and their systems and setup. I will admit this one took just a few more steps than I anticipated but again I reached out to their support team and things started working better. This is my original review, just ignore my ignorance. I only leave it so you can see my honest reviews and opinions as I set this product up. And yes, I purchased this setup with my own money and no discounts. Original: I really want to like these cameras and maybe one day after some firmware updates I will. I purchased this and it's my honest review. Pros. 1. Pan tilt zoom is great. 2. Dual cameras is great 3. Setup was a breeze with the Homebase 3. 4. Install was super simple and I hardwired them for constant power. 5. Picture quality is great even in zoom. 6. Much more. Cons. 1. The app has some lag occasionally. There is no way that I have found so far to quickly mute the motion detection on the cameras. So when I go to mow or work outside on something I'm constantly setting off the alarm. I have to go deep into the app for both cameras and uncheck the alarm and or motion. Then I have to go back and recheck those boxes to get the alarms I want. With Ring, you can mute the motion and alarms in two clicks on the main screen. It also seems to be very sensitive to snow. I have lowered the sensitivity down to one. Which I don't like but it seems to keep the snow from triggering the alarm. 2/4/26 Edit: Eufy tech support is pretty good, they were able to help get some things working. Overall I would recommend this camera system as it's benefits outweigh the cons. Just overall the app seems heavy and bulky to use. You have to go between multiple screens to make simple changes. I would love for someone to correct me. I have not reached out to their tech support as I've only had them installed a couple of days now.

The media could not be loaded. I’ve been using the EufyCam S4 for about 5 days, and I’m genuinely impressed with how advanced and reliable it is. One of my favorite features is the motion tracking. The camera doesn’t just detect movement—it actually follows the person or object as it moves across the area. That gives me much better coverage and peace of mind because I know the camera won’t miss important activity. The dual-camera setup is another feature that really stands out. Having both a wide-angle view and a tracking camera working together provides excellent surveillance coverage. The wide lens captures the full scene, while the tracking lens zooms in and follows movement, which helps eliminate blind spots around the property. The 4K video quality is excellent. The image is incredibly sharp and clear, making it easy to recognize faces, vehicles, or other details even at a distance. Daytime footage looks great, and night performance is also very solid. I also appreciate how well the camera integrates with the Eufy HomeBase S380. Setup was straightforward, and everything works smoothly through the Eufy Security App. Being able to manage alerts, recordings, and settings from the app makes the system very convenient to use. Overall, the EufyCam S4 delivers excellent picture quality, intelligent motion tracking, and innovative dual-camera surveillance. If you’re looking for a high-quality security camera with advanced features and reliable performance, this one is definitely worth every penny spent. I highly recommend it. PS - If you want to expand the storage capacity of your Homebase, I strongly recommend going with SATA SSD. Which Should You Choose? 🏆 Best overall for surveillance / many cameras: Seagate IronWolf 125 — it’s designed for NAS, high TBW ratings, and multi-user workloads, often exceeding the endurance of typical consumer SSDs like WD Red. 💪 Balance of performance and price: IronWolf 110 — a reliable SSD with good endurance for 24×7 recording without going into the expensive enterprise tier. 📈 Enterprise-grade durability: Synology SAT5210 — excellent endurance specs and NAS-oriented firmware if budget permits.

I was very intrigued by these cameras but I have to say I am very happy with the purchase. The video quality is good the battery life so far seems good with the solar mount. Connectivity could be faster but it loads up pretty fast. The set up was very easy as well. Do be warned that for some reason until you connect/activate them they seem to not charge. I tried to pre charge 3 before setting them up 1 by one and noticed after the first one that the rest did not charge at all despite being on a charger for a whole day. I really love the moveable camera portion definitely enhances security.
