With an i-PRO camera, is it possible to ensure redundancy of the power supply using both AC adapter and PoE power supply at the same time? [i-PRO / i-PRO smart HD]

Answer

It is not possible to use AC adapter and PoE power supply together as a means of power supply redundancy. When both AC adapter and PoE power supply are connected at the same time, the supply with the higher voltage takes priority and PoE power supply is used. If PoE power supply fails, AC power supply does take over. However, failure of PoE power supply means that there is an abnormality in a network device or a cable, and camera data cannot be sent out via the network. Therefore, using AC and PoE supply at the same time cannot be regarded as a means of ensuring power supply redundancy.
