Philips 4200 Series vs Dermum S1: Which smart lock is better in 2026?

Smart locks with handlesets offer a convenient way to upgrade an entire front-door setup without installing a separate electronic lock and exterior handle. 

The Philips 4200 Series WiFi Smart Door Lock and Dermum S1 Smart Lock both combine keyless access with matching door hardware, but they target slightly different users.

Philips 4200 Series vs Dermum S1 specs

Philips 4200 Series WiFi Smart Door Lock With Handle

The Philips 4200 Series is designed for homeowners who want a more connected front-door experience. Its biggest advantage over the Dermum S1 is built-in 2.4GHz Wi-Fi, which allows remote access and activity management without purchasing a separate gateway.

Fingerprint recognition is another major strength. Philips claims approximately 0.3-second biometric access, giving users a quick way to unlock the door without entering a PIN.

The matching exterior handle also makes this a complete entrance upgrade rather than simply a replacement deadbolt.

Dermum S1 Keyless Entry Fingerprint Smart Lock With Handle

The Dermum S1 takes a more straightforward approach to smart entry. 

Rather than including built-in Wi-Fi, it primarily uses Bluetooth for smartphone connectivity, with a separate gateway required for remote access and voice assistant functionality.

It also includes auto-lock, anti-peeping password protection, and an anti-theft alarm, making it a practical choice for homeowners, landlords, and rental hosts who want multiple ways to provide access.

Which smart is better?

The Philips 4200 Series is the better choice for users who prioritise built-in Wi-Fi, remote access, fast fingerprint unlocking, and smart-home convenience. Its integrated connectivity makes it the more complete connected solution.

The Dermum S1 is better suited to users who want more physical access options, particularly RFID cards, without necessarily needing Wi-Fi connectivity from the beginning.
