Q: QuestionI live on a busy street: will the camera constantly pick up the road traffic. My door faces the street

Asked 2 days ago by mkgirl1805.

• A:Answer Like you my front door exits RIGHT onto the sidewalk of a very very busy street (both vehicular+pedestrian). While I do not have this model, I have had the E340 Video Doorbell installed for over 2 years. Within the settings (accessed via Eufy App) you can Select "Activity Zone", "Distance of Sensitivity", "Detection Type(s)" which can be individually toggled on/off ie Human Detection, Human Recognition, Vehicle Detection, Pet Detection, ALL Other Motions. IF you have your videos stored directly to the smart lock (not a HomeBase3 etc) it's easy enough to "Select All Today's Events" to delete them at the same time. I have the S330 Smart Lock on the door leading into garage from inside house. It has these same features. So I would "assume" the FamLock S3 does as well. FWIW - I've been very happy with all of my Eufy Security products.

Q: QuestionWhat is the max thickness of the door this smart lock can install? We have a pivot door thickness ~2.5”, can this model fit?

Asked 1 month ago by Anonymous.

• A:Answer We couldn't retrieve information about the maximum door thickness that the eufy FamiLock S3 Max WiFi Replacement Deadbolt supports. Without this specific data, I recommend checking the product specifications to see if it supports the 2.5-inch thickness of your pivot door. If you'd like further assistance, feel free to reach out with any other product-related queries!

Q: QuestionI have a Eufy S231 now. Can this new model easily replace it with little trouble? Will I need my locksmith to help? My current setup is very finicky and the locksmith really had to work at it to get it perfectly aligned. I just want to make sure this one.

Asked 3 months ago by JD.

• A:Answer We could not find specific information about replacing the Eufy S231 with a new model, such as the FamiLock S3 Max, including whether a locksmith will be required. However, if your current installation required precise alignment and detailed work by a locksmith, it is possible that similar attention to alignment may be necessary for the new model. For precise compatibility and installation details, it's advised to confirm that the fitting dimensions of the replacement model match the existing setup. Also, instructions provided with the FamiLock S3 Max may clarify whether any special tools or professional help are needed, making the process smoother.
