Hi @Rida1!
I can confirm the MV can connect wirelessly when powered by a PoE injector - my MV63 and MV93 at home are connected via wireless profile only, and are powered via Cisco AIR-PWRINJ6 PoE injectors.
You may want to call in to support for further advice on the specific steps in your scenario, as the camera needs to report a stable configuration for that 30 minute period to be able to retain the wireless profile configuration thereafter.
