The cameras from the "EufyCam 2 Pro 3+1 Kit (2304 x 1296 pixels)" can generally be integrated as additional cameras in an existing base station from the EufyCam 2 Pro series. It is not absolutely necessary to use the base station supplied with the kit, as the cameras are compatible with the HomeBase 2 and can be connected to it. This makes it possible to expand an existing system with additional cameras from the same series.
