Best Smart Doorbell and Smart Lock Combo for Rental Properties
A smart doorbell + smart lock combo is the most powerful security upgrade for rental properties. Here's the best no-fee bundle for landlords and Airbnb hosts.
About Other Combos
Most smart doorbell and smart lock combos come from different brands (e.g., Ring doorbell + August lock), requiring separate apps and often a monthly subscription for cloud recording. The best combo for rental properties uses one ecosystem, one app, and no monthly fee.

Bottom line
A smart doorbell + smart lock combo is the single most impactful security upgrade for a rental property. The doorbell lets you see who's at the door, and the lock lets you manage guest access without physical keys. The best combo uses one ecosystem, one app, and no monthly fee — Cryptronics offers exactly that.

Why a doorbell + lock combo matters for rentals
Rental property owners and Airbnb hosts face two key problems:
- Key handoff — physical keys get lost, copied, or not returned. Guests arrive at odd hours and need access.
- Front-door awareness — who is at the property? When did guests arrive? Are packages being delivered?
A smart doorbell + smart lock combo solves both: guests enter a temporary code on the lock, and the doorbell camera shows you when they arrive. No physical keys, no meetups, no monthly fee.

Why Cryptronics is the best combo for rentals
One app, one ecosystem
Both the doorbell and lock work in the Tuya Smart / Smart Life app. No juggling two separate apps like you would with a Ring doorbell + August lock.
No monthly fee
Cryptronics doorbells support local SD card storage. No cloud subscription required. The lock's app features (guest codes, audit trail, remote management) are free.
Guest access without app
Guests enter a temporary passcode on the lock's keypad. They don't need to install any app. This is simpler than August, which requires guests to install the August app.
Affordable
Starting at $89 for a doorbell + lock combo, Cryptronics is significantly cheaper than Ring + August ($215+) or Eufy doorbell + Eufy lock ($250+).
What to add to the combo
For a more complete rental security setup, add:
- One Door / Window Sensor — $29, on the back door
- One Water Leak Sensor — $25, under the kitchen sink
- One Exterior WiFi Camera — $59, for broader exterior awareness

Eufy doorbell + Eufy lock ($250+)
Eufy offers both doorbells and locks in one app, but their locks start at $169.99. The combo is more expensive than Cryptronics. See our Cryptronics vs Eufy comparison.
Wyze doorbell + Wyze lock ($125+)
Wyze offers both, but their lock starts at $89.98 and the doorbell at $34.98. Wyze cameras are cheaper, but the lock lacks fingerprint access. See our Cryptronics vs Wyze comparison.
FAQ
