Combining the monitor and DVR into a single unit is a very stupid idea because it means that the full functionality is never available.
If the unit is mounted on the handlebars:
- Parking protection is not available because the unit will be stolen.
- Units that are not fully waterproof will stop working when they are disconnected and moved under the seat as recommended, who needs recording in the rain.
If the unit is mounted under the seat:
- no use can be made of the monitor
One could remove the tank and re-wire the unit every time one leaves the bike or it rains, but that would make you stupid.
I have not found and model with a separate monitor and DVR, where the monitor can be removed without stopping the protection.
Every manufacturer describes an impossible set of functions for their device without addressing the above. Are they unaware of the problem or deliberately ignoring it?
