This is one of my EASIEST 5-star reviews. This is a GREAT product, and no I don't own stock in Eufy.I wanted to replace my old DVR-based wired system with a more modern system of wireless video cams. I looked at other brands, and based on the YouTube vid's I watched, the Eufy S340 seemed to do it all. So, I bought the starter pack (2 cams and a Homebase) to try out, and it did everything that Eufy claimed, and more. On that basis I bought 5 more cameras and have not been disappointed. I'm not going to rehash all of the S340's features. I suggest that you watch any of the YouTube videos about this product. I will only list the features that wildly exceeded my expectations, along with some installation tips:1. Customer Service. One of my 7 cams worked perfectly except that the battery wouldn't fully charge to 100%. It only charged up to 44%, but that was still more than enough power for it to function perfectly. But I wasn't happy with what was likely a battery that had been on a warehouse shelf a bit too long, so I called Eufy product support. *Before* I was off the phone with them, they had a replacement on its way to me, without first having confirmed that I had shipped the old one back. THAT is what I call exceptional CSX.2. Installation wizard. The installation process is via an automated wizard that's activated by your mobile phone's Eufy app, and it's terrific. It walks you thru every step of the installation, and I've never had a problem installing a cam. It's a brilliantly designed piece of software that even takes you thru updating the camera firmware to the latest version.3. Solar panel mounting tips. On my eaves, my concrete roof tiles extend over the edge of the fascia board by a couple of inches. This can make it difficult to install the camera with the solar panel attached directly to the top of the cam. Also, some locations don't get enough direct sunlight. So, I mounted the solar panels in some locations 5 or 6 feet away from the camera and I used these really great stand-offs for the solar panels:https://www.amazon.com/dp/B0BKGCFNTD?psc=1&ref=ppx_yo2ov_dt_b_product_detailsThese are great, too, but don't provide as much of a stand-off distance:https://www.amazon.com/gp/product/B08RNHSMCL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1I used both of these in various locations, depending on how much stand-off distance I needed. They are great products. When you install the solar panel in a different location than the camera, you'll be using the provided extension cable that's about 10 feet long. I wanted to keep this installation neat and professional looking, so I used these cable clips to fasten the cable to the inside of the eaves fascia board:https://www.amazon.com/dp/B08RMNPCYN?ref=ppx_yo2ov_dt_b_product_details&th=14. Eufy app. The downloadable app is amazingly complete. It has more panels and info on it than I've seen in other more sophisticated products (like my Generac standby generator). You can setup camera sensitivity, AI tracking, sound, video quality, and on and on. I have one camera focused on my fishpond and I've set it to a slightly higher sensitivity than the other cams, and I've told it to recognize animals. It almost always records a huge great horned owl in the middle of the night when I'm sleeping, and it's going for a drink of water. I've also set that same camera to trigger the built-in siren and strobe light if it sees anything that's coyote-sized trying to catch my goldfish or koi.5. Panning and close-ups. You can pan the cameras while you're viewing them remotely, and you can do a closeup using a finger drag on your screen, or you can switch to the 3x lens for an even more detailed close-up. All of these features work flawlessly and in real time. What a great thing to have when you're on vacation!6. Serious security. I've used the configurable "Automation" capability to "knit" my cameras together into an automated system that will set off alarms under circumstances that I've defined. For instance, I've set my system to behave normally from 6a to midnight. During that time, if any camera detects movement (definable by camera), the system records the event and stores it. BUT AFTER MIDNIGHT and before 6a, if it detects humans or cars on my driveway, all hell breaks loose. That means that those triggered cameras flash a strobe, sound a siren, and send me an alert that wakes me up. In such a case, I could bring that camera up on the screen, and I could turn off the siren and yell at the unwanted visitor(s) through the built-in loudspeaker.7. Camera wireless range. I noticed that it took a while to access my farthest cameras using the Eufy app. They were attached in a location on the eaves outside my garage doors. I simply installed an additional eero Wi-Fi Extender in the garage, and that solved the problem. I already had an eero router and other eero extenders in order to provide better performance for my other network devices around my large-ish house, so I just needed an additional extender.---------------------------------------------------------------There's really nothing about these cameras or the system software that I don't like. I can't address reliability because I've only had them in for a few months now, but so far, so good. I can't recommend this system highly enough.BTW, all my cams are connected to my Eufy Homebase S380, which is a separate product, and which you should buy with your first camera purchase. It's $149 by itself, but Eufy has a pkg that includes two cams and a Homebase for a substantial discount.

I needed to use it because the camera is actually mounted under an awning in the shade, and there was more than enough room for a short stand-off. The second picture shows a long stand-off. I needed to use a longer one in order to clear the roof tiles and to get a good view of the sun.
