The network quality where the camera is located can affect the stability of the device connection and viewing via the app. Besides signal strength, it's important to consider if there are other high-traffic activities on the network. Viewing the camera during these activities might lead to slow or even failed connections, especially if you're trying to access high-definition live views.

Additionally, the network situation of your mobile device shouldn't be overlooked, especially when remotely managing the camera (e.g., using mobile data). Unstable signals, VPN usage, or device lag (due to aging hardware or running too many apps simultaneously) can also impact the smoothness of viewing the camera feed.

When it comes to the doorbell detection feature, there are two important points to consider.

First is the detection settings of the doorbell: since the device is battery-powered, it remains mostly in sleep mode, only waking up when motion is detected through the PIR sensor, when someone rings the doorbell, or when live viewing via the app. Therefore, it's essential to adjust the doorbell's wake-up sensitivity, person detection sensitivity, and verify the correctness of the activity zone settings.

Second, because battery-powered models rely on the PIR sensor to wake up the camera, the installation position and angle can affect the detection performance. In your case, where person detection is required, improper installation angles may prevent the camera from recognizing people, leading to failure in triggering detections (video recording).
