Very nice 4K image and night viewing. Good WiFi coverage distance outdoors. But compared to the wired E330 Pro camera, the S3 Pro is a letdown. Set at max sensitivity, it won't detect a human > 40 ft. Yet will unfortuntatly detect leaf movement and shadows. Won't detect a cat > 20 ft. Clips of motion start late and end early. Snapshot every 3 mins is working on one camera and not on the other.
I have just upgraded our eufyCam 2 Pros to the S3 Pro and it has been a great advance of facial recognition and improved camera resolution, especially the night vision.
This camera lives up to all the hype. I'm very pleased with the clarity of the picture day and night. My camera is in a very low light/sunlight area and the power has only dropped to 98% then shoots right back up to 100% Eufy you have a solid winner here.
