Test report
The power pack, drilling template, screws, dowels, instructions and of course the camera are supplied.
Functions:

The connection cable is permanently installed with the camera.
This may be unfavorable if you want to lay the cable through a wall, so our products are battery-powered or solar-powered.

Alarms are stored on the SD card, you can view them later in the app.

The app is always required for configuration. You have to register there first.
The easy configuration in the app is a plus.
Motion and sound detection are possible. You can also set motion tracking, which also works, but the camera rotates horizontally and vertically. Depending on where the camera is mounted, 2 axes are actually required for motion tracking.

The camera also has a speaker, you can talk through the app. That also works very well.
However, you cannot limit your field of vision in advance, you always have a full field of vision.
You have to be careful with outdoor recordings, since public areas are not allowed to be recorded.

It is very good that the camera can be controlled via the app. Zoom works too.
You can also have your cell phone alert you to movement or noise. It is important here that the app has the appropriate permissions.

Night vision is good, with the integrated LEDs it can also illuminate the surroundings.

Security:
With such cameras that can be accessed via the Internet, you have to trust the manufacturer, because you cannot make any security settings yourself. One must also hope that the manufacturer will react quickly when security gaps are found and update the firmware.
