A:AnswerHi there,
When you're using a USB and Sync Module 2 for local storage, you will be able to see the clips from your Blink app. You can also remove the USB and view on a computer if you wish.
A:AnswerFrom my knowledge, you only should need one sync module. We have 4 cameras in total on our sync module, 1 doorbell camera and 3 mounted cameras.
A:AnswerHi Stacey, and thank you for your question. The Blink Video doorbell can be used wireless but will not ring your existing doorbell chime if not hardwired. However, you will receive notifications when the doorbell is pressed through the blink app on your cell phone or tablet. I hope this helps, have a great day!
