power source
The TCL Palm Vein Wi-Fi Smart Deadbolt uses a massive 10,000mAh rechargeable battery. This design supports up to 8 months of operation on a single charge.

connectivity
Connectivity standards differ significantly between these two locks. The TCL Palm Vein Wi-Fi Smart Deadbolt connects via Wi-Fi. It relies on this connection for remote app access and smart home integration. The TCL Palm Vein Smart Deadbolt features Matter over Thread connectivity alongside built-in Wi-Fi. This dual approach allows it to connect to Apple Home, Alexa, Google Home, and SmartThings. The Thread mesh network provides reliable low-power connectivity even if your main Wi-Fi goes down. This makes the second model more versatile for users with diverse smart home ecosystems.
smart home compatibility
Both locks support major voice assistants, but the second model offers broader platform support. The TCL Palm Vein Wi-Fi Smart Deadbolt works with Alexa and Google Assistant. You can lock, unlock, and check status via voice commands. The TCL Palm Vein Smart Deadbolt supports Apple Home, Alexa, Google Home, and SmartThings.

access methods
Access options provide flexibility for different household members. The TCL Palm Vein Wi-Fi Smart Deadbolt supports six entry methods: palm vein scan, touchscreen passcode, TCL Home App, voice commands, NFC card, and physical key. This variety allows you to generate temporary codes or use cards for service providers. The TCL Palm Vein Smart Deadbolt lists palm vein as its primary access method in the key specs.
