It's the third K&F Concept-cam I buy. I needed a waterproof camera to put in the seaside garden and this does its job well. The images are very clear even at night thanks to the powerful infrared LEDs that illuminate the scene. The motion detection function doesn't miss a beat and it's convenient to adjust the part of the area where motion should be detected. By inserting an SD card every 10 minutes, the IPCAM records continuously for 10 minutes and is immediately activated even when motion is detected. It is possible to record in a continuous loop on an SD card or send FTP on a hard drive connected to the WiFi router. The videos have a very clean audio track and it is possible to interact with the IPcam via the microphone function of the CamHi app. The setup is super easy with both the CamHi and CamhiPro apps. I set up sending a notification and xEmail screen for every movement as can be seen in the attached photos. The cam is small enough to be used discreetly in any environment, even externally, and yet the image resolution is of excellent quality as can be seen in the photo and the WiFi signal is stable and powerful.
