The home function ensures the camera head is automatically aligned to a straight position, ensuring the camera "looks straight ahead".
Moreover, when the user presses the HOME key, the camera head aligns itself so that the display is parallel with the ground above (this function is deactivated if the camera head faces 90° upwards or downwards. Under these circumstances, the optics can only be guided forwards).

To determine the grade described under para-
graph 8.3.1, the camera head must be aligned
straight.

Guide accessories
T This section contains some recommendations based on our experience about the selection of guide accessories for the inspection in tubes and ducts.
As all pipes and chimney systems are different, the user has to decide about the guide accessory in every single case. For the selection of the correct tool it is important to consider that the guide accessory has to facilitate the introduction and the extraction of the camera head, as well as an adequate guidance. The danger of jamming or getting stuck in the tube has to be avoided.

When fitting the replacement dome, make sure you cover all of the thread to ensure it is properly tightened. Otherwise, it cannot be guaranteed that the camera head is properly sealed, and malfunctions can occur as a result of water and dirt penetration.
