The included chime can get loud enough for household alerts across rooms or floors, though reviewers discussed chime volume rather than a separate siren.

Product 2: eufy Video Smart Lock E330

Product 2: eufy Video Smart Lock E330
4.2

Wrong-try protection can lock the device down after incorrect PIN or fingerprint attempts, giving it a supported failed-attempt lockout feature.

Backset compatibility
Product 1: eufy Video Smart Lock S330
4.6

Backset support is well documented for common 2 3/8-inch and 2 3/4-inch sizes.

Product 2: eufy Video Smart Lock E330

Product 2: eufy Video Smart Lock E330
4.1

Camera and doorbell performance is generally strong for 2K clarity, night vision, and detection, but field of view and placement limitations reduce consistency.

Door-sense
Product 1: eufy Video Smart Lock S330
3.1

Door-sense style features are mixed: one review praised leaving detection, while another said auto-lock did not know whether the door was open or closed.

Product 2: eufy Video Smart Lock E330
2.0

Door-sense is weakly supported because one reviewer specifically wanted a sensor to know whether the door is open or closed.

Door compatibility (deadbolt fit)
Product 1: eufy Video Smart Lock S330
3.3

Deadbolt fit is the biggest installation caveat: it replaces a standard deadbolt but can be sensitive to strike-plate depth, alignment, and size constraints.

Product 2: eufy Video Smart Lock E330

Product 1: eufy Video Smart Lock S330
