Hi Charliel,
Here is the information I have from Warranty, safety and regulatory information - Google Nest Help.
Medical Device Interference
Your device uses radios and other components that emit electromagnetic fields, and also contains magnets. These electromagnetic fields and magnets may interfere with medical devices, such as pacemakers and other implanted medical devices. Always keep the device at a safe distance away from the medical device. If you have questions about using your Google device with or near your medical device, consult your healthcare provider before using your Nest Cam with floodlight. If you suspect your Nest Cam with floodlight is interfering with your medical device, turn off your Google device and consult your physician for information specific to your medical device.
