A monitoring camera includes at least one emitter of perceivable signals, a tilt sensor arranged to generate a signal representing a tilt value indicating a tilting angle of the monitoring camera, and an emitter driver arranged to drive the at least one emitter of perceivable signals in response to an adjustment indicating signal which is based on the tilt value signal. The monitoring camera may be arranged to perform a method including entering the camera into an installation mode, generating a tilt value signal at a tilt sensor within the monitoring camera, and indicating by means of at least one emitter of perceivable signals whether the monitoring camera is positioned in a desirable tilt or not based on the generated tilt value signal. The method may further include exiting the installation mode and entering into monitoring mode when satisfactory tilt is achieved. |
