Compare eufy Smart Lock C33 and FamiLock E34 on key features like unlocking methods, power supply, and remote access to find your ideal smart lock.
Quick answer
Choose the eufy Smart Lock C33 for simple, affordable fingerprint access with integrated Wi-Fi, or the FamiLock E34 for higher security with palm vein scanning and a rechargeable power system.
Unlocking technology and security level
The C33 uses advanced fingerprint recognition built into the handle grip, which is convenient for most households and learns your fingerprint over time. The E34 goes a step further with palm vein scanning, which is nearly impossible to forge and works even if your fingers are wet or dirty. If maximum security is your priority, palm vein technology is the clear winner.
Power and connectivity differences
The C33 runs on 8 AA batteries and includes integrated Wi-Fi for remote access and notifications. The E34 uses a dual power supply with a 10,000mAh rechargeable lithium battery, so you won't need to replace disposables. Both offer remote control via the app, but the E34's power system is more convenient for long-term use.
Trade-offs to consider
- Unlocking method: C33 uses fingerprint; E34 uses palm vein. Fingerprint is faster to enroll but can be affected by dirty/wet fingers. Palm vein is more secure but requires a slightly larger hand movement.
- Power source: C33 uses 8 AA batteries (replace periodically); E34 has a 10,000mAh rechargeable lithium battery (lasts longer, no disposable waste). If you dislike changing batteries, the E34 is more convenient.
- Remote access: Both offer remote control via the app, but the C33 includes integrated Wi-Fi out of the box. The E34 also supports remote access, but check if your setup requires a separate hub (not specified). For simplest setup, the C33 is ready to go with built-in Wi-Fi.
