One thing you can probably use is the PoE cable you already ran to the EE cameras... remove the EE camera, mount the Meraki camera, and connect the PoE cable.
What features are they lacking or wanting to improve from EE? We can then offer how Meraki MV addresses those needs/pain points.
(We replaced a traditional NVR IP camera system with Meraki MV in 2019, 102 cameras)
