S2 4K Solar Security Cameras Wireless Outdoor - Radar+PIR Detection, AI Face Recognition, Auto Sunlight-Tracking, Color Night Vision, IP67, No Monthly Fee, Local Storage, Featured at CES 2025

Excellent camera. Purchased five with four in place now for a month. Easy setup with charging, firmware upgrade and immediate connection to wifi. Haven't had any issues with wifi with repeaters up to 20m from camera. A bit of flexibility required initially to position for best effect by day and by night to get the sweet spot for both while experimenting with the detection sensitivity and the 145 degree field of view. Solar charging has been excellent with battery retained at >95% on all cameras. When positioned correctly night vision is very good. Very few false alerts from PIR/radar. 4k resolution provides a very good picture and micro-sd card recording and playback has worked very well. I have found the baseus security app to be very good and with good options to notify, record, capture etc. Cameras have been up in strong winds and heavy rain and maintained performance including connectivity.

Update: Baseus sent me a new camera to try at no charge. I was able to connect to the camera from an Android phone by turning it into a mobile hotspot. After the connection, the camera updated its firmware to resolve the connection issue. After that, I was able to connect the camera to my system alongside my other Baseus cameras and use my iPhone to control it. The support team really has been outstanding. In the few days since I reported this issue, they have contacted me at least a half-dozen times with possible fixes. They ARE trying. I am giving them five stars now for this effort AND because I have 7 other Baseus cameras (X1-Pro and S1 interior pan-and-tilt cameras) that are outstanding in every way (see my review of the X1-Pro here on Amazon). This S2 outdoor camera is equally excellent. If you can get someone to loan you an Android phone for less than 5 minutes, updating the firmware is very easy. Make sure the phone has cell service; this is critical*.Follow the steps below (settings may vary slightly across different phone brands):1. Open Settings on your phone2. Go to Network & Internet3. Select Hotspot & tethering4. Tap Wi-Fi hotspot → Hotspot settings5. Find AP Band → select 2.4 GHz → save and turn on the hotspot6. Then try connecting the camera to this 2.4GHz Wi-Fi hotspotThis will fix the issue!ORIGINAL REVIEW: We have four Baseus X1-Pros, no issues, great camera. But this S2 has problems connecting to some networks. Tried everything, got good tech support to a point: "We have identified that the current Wi-Fi connection issue with the S2 camera may be related to a compatibility problem with the Wi-Fi chip driver. To address this, a firmware installation is required, which can be completed by connecting the camera via a mobile hotspot.-Could you kindly check if you are able to borrow any Android device or a Windows laptop to create a 2.4GHz Wi-Fi hotspot?Once connected, you can proceed with installing the firmware on the S2 camera, which should help resolve the issue."We found a friend with an Android phone, but no go; still could not connect*! This is a problem buyers should be aware of. Some Nextwork hardware may work (obviously, many customers are fine), but some may not. Here is why. I'm going to send the camera back and get the newer X1-Pro, which works fine and is a superb product. Baseus support was very good and timely, but they need to ship cameras with a firmware that supports all networks (our is from Xfinity). I can highly recommend the Baseus X1- Pros.*The camera I first borrowed did not have cell service, so it didn't work as a hotspot despite showing it as one. When I borrowed another friend's Android phone that did have service, the hotspot worked, and I was able to update the firmware.

I give it one starthen changed to 3Now back to one for the simple fact of WiFi range and connectivity and playback. With the wireless access router in the same area as the camera and it fails to playback, takes minutes to open a clip, not all the time but enough for me to pull my hair out. On top of that it records an incident almost at the end. You get an alert, check the clip and the subject iqs out of the view and you watch empty scene.I’m disappointed with this device. The sound quality is poor, and I couldn’t recognize my own voice when I recorded myself. There’s also an issue with the alert, as the image it displays is often inaccurate or fails to appear at all. The WiFi range is limited, and when viewing the screen live, the camera doesn’t record what’s being watched. You have to press the record button manually. Additionally, when used as a spotlight, the camera won’t record. Despite having a facial recognition option, the Terms of Service essentially authorize the app to use your data however they please. There are only two recording options: 4K or 720p, with no in-between options. The 4K recording takes a long time, and the 720p option is outdated. Furthermore, there are times when the camera fails to record even though it’s fully charged, and there are missing hours or calendar entries with no data.

Didn’t work for me. Sent it back

As a standout product from CES 2025, the Baseus S2 Solar Security Camera is a remarkable leap forward for home surveillance. Its most compelling feature is its autonomy; the combination of solar power and innovative sunlight-tracking technology means you can virtually install it and forget it. The crisp 4K resolution provides incredible detail, while the color night vision ensures clarity around the clock.What truly elevates the S2 is its intelligent detection system. By merging Radar, PIR, and AI Face Recognition, it significantly minimizes false alarms, focusing only on genuine security events. With an IP67 weatherproof rating, it’s built to endure the elements.The absence of mandatory monthly fees, thanks to its reliance on local storage, makes this a financially savvy choice for long-term security. The Baseus S2 offers premium, next-generation features without the recurring costs, delivering true peace of mind in a single, powerful package.

This is my second review. At first, I was very frustrated because the camera wouldn't do anything before a firmware update, and the update repeatedly failed to complete. I think it was a wi-fi problem - theirs, not mine, and something other reviewers have noted. In any case, I moved it right next to my main router and the update completed. Maybe just coincidence if the problem was really their update server(s). In any case, everything has been fine since. Detection and picture quality have been great, the solar panel is sufficient to keep it charged, and it doesn't even seem to have had any trouble with connecting since that first day. Still knocking off a star because of that out-of-the-box experience, but otherwise excellent.

I chose the solar-powered version for outdoor use, and it’s been very convenient with direct sunlight power and no need for charging. The video quality is excellent, with both HD and ultra-clear options, and the motion detection is very responsive—recording instantly and sending timely alerts whenever someone appears. I can watch live or view past footage anytime through the app. After several days of use, the battery still has 90% power, showing strong endurance. Installation was simple, it connects easily to home Wi-Fi, works well even on a plain wall, and the image remains clear even at night without lights. Overall, it’s affordable, easy to use, and I’m very satisfied so far.

After a week of use, I'm finally free from false alarm notifications. My old camera would go crazy whenever the wind blew—even rustling leaves triggered motion alerts. I upgraded to the S2 specifically for its dual radar and PIR detection, and so far it's proven effective. It's only triggered for actual people or vehicles. The solar panel automatically rotates to track the sun—it felt pretty novel when I first installed it. The battery has stayed above 90% these past few days, and I haven't had to recharge it yet. But it's only been a week—we'll see how it holds up when cloudy days roll in.

Excellent, easily installed and really effective!
