A:Answer Hi booda, thank you for your question. A Blink Sync Module 2 can support up to 10 Blink devices so you can add more cameras to the same sync module. Multiple Sync Modules can be used within the same Blink account to manage more devices and create separate systems. Each system, managed by a Sync Module, can have up to 10 devices. I hope that helps, have a great day!
