Tamper and suspicious-activity protections show up via mentions of tamper alarms, loitering alerts, and wrong-try lockouts. Sensitivity and alert volume can usually be tuned in the app.
Pros: Physical attack resistance, Weather resistance
Cons: Value and Price
Tamper/anti-theft features are commonly associated with the keypad ecosystem and can be enabled/managed in the app. Reviews mention the availability of tamper alerts, but most do not deeply stress-test sensitivity...
Pros: Existing hardware reuse, Battery
Cons: Finish durability, Auto-unlock
Tamper detection is described as present with alarms and instant alerts for suspicious activity. Sensitivity is not quantified, but reviewers present it as a meaningful extra security layer.
Pros: Value and Price, Lock/unlock speed
Cons: Geofencing
Anti-tamper and unusual-activity detection are referenced (including tamper events surfaced in some ecosystem apps), but few reviewers deeply tested sensitivity or false-alarm behavior.

Pros: Weather resistance, Warranty and support

Pros: Hub requirement, Backset compatibility
Cons: Door-sense, Smart-home integration (Alexa
