Hello!
Thank you for your patience. I wanted to do my due diligence and check with related teams before responding to make sure that my answers are accurate. 
First, sorry to hear that you’re experiencing this! That does sound really concerning and we’re glad you posted. A lot of the answers you’re looking for are publicly available and I’ll put the links here, but a lot of the answer boils down to: Our system is set up to prevent employees from getting that access. Wyze employees aren’t given remote access to devices and we have built-in policies to enforce this.
We would definitely like to look into your experience because we take this very seriously. If you’re interested, please get in contact with our Security Team by emailing security@wyze.com. We’ll need the MAC of your camera (can be found in Camera Settings or on the sticker on the product) and the email for the account paired with the camera. It would also be super helpful if you give us the time of this incident to the best of your ability to help us find the right time in our logs to look at.
Here’s some information about how you are protected (including from us):
Here’s information about the active monitoring and how they don’t have access either:
"Will monitoring service (Noonlight) have access to the video feeds and/or local storage?
No, Noonlight will not have access to your videos on cloud or local storage (microSD card).
How is my data stored? Is my privacy protected?
Wyze is serious about customer privacy.
Your private data, such as your name, phone number, home address, PIN, and Safe Word are encrypted.
We will send your name, phone number, home address and Safe Word to the monitoring center (Noonlight) for safety verification and dispatching purposes. Once the alarm is resolved, our collaborating monitoring center will remove your personal data.
Your PIN will never be seen by Wyze employees or third parties.
Videos and/or the live streams from your Security Cameras are not shared with any Wyze employees or third parties (including Noonlight and the monitoring center)."
That is from the Details section from the Wyze Home Monitoring page here:
Again, thanks for letting us know about this issue. We’re so sorry that you and your friend had this happen and we appreciate you giving us the opportunity to figure out what happened here.
