Solity GP6000 vs Interlock Mercury X6: Battle of the Smart Locks
Interlock Singapore
Choosing between the Solity GP6000 and the Interlock Mercury X6 depends on whether you want a reliable biometric lock or a complete smart entrance system.
- Best for Traditional Biometric Access: Solity GP6000 – Ideal for users who want a fast, high-quality Korean push-pull lock focused on fingerprint speed.
- Best for Full Smart Door System: Interlock Mercury X6 – Superior for homeowners wanting 3D facial recognition, a built-in HD camera viewer, and two-way intercom communication.
While the GP6000 is a top-tier biometric lock, the Interlock Mercury X6 offers a more "future-proof" experience by integrating security cameras and advanced palm vein technology.
What Is the Solity GP6000?
The Solity GP6000 is a premium push-pull digital lock from Korea’s leading smart lock manufacturer. It is designed for those who value speed and mechanical reliability. Its standout feature is the ergonomic handle with an integrated fingerprint scanner, allowing you to unlock and push the door open in one fluid motion.
It uses the Solity Smart App (via WiFi or Bluetooth) for remote management, making it a solid choice for HDB and Condo owners who want a trusted, fire-rated biometric lock without unnecessary bells and whistles.
What Is the Interlock Mercury X6?
The Interlock Mercury X6 is a next-generation "all-in-one" smart entrance system. Unlike traditional locks, it replaces your peephole with a built-in HD door viewer and an internal 4.5-inch IPS display screen.
It is one of the few locks in Singapore to offer 3D Facial Recognition and Palm Vein Recognition, allowing for truly hands-free entry. Operating on the global Tuya Smart/Smart Life ecosystem, it allows you to see, speak to, and unlock for visitors remotely from your smartphone.

Security and Biometric Technology
The Solity GP6000 relies on a high-speed capacitive fingerprint sensor (recognition in ~0.9 seconds). This is excellent for daily use but requires physical contact.
The Interlock Mercury X6 takes security further with Palm Vein Recognition. Instead of scanning the skin surface, it maps the unique vein patterns under your skin using infrared light. This is more secure than fingerprints because it is nearly impossible to spoof and works even if your hands are dirty or wet. Additionally, its 3D Facial Recognition provides a contactless "walk-in" experience that the GP6000 cannot match.
Smart Features and App Ecosystem
The GP6000 uses the Solity App, which is dedicated solely to Solity products. It is straightforward, offering access logs and remote unlocking.
The Mercury X6 uses Tuya Smart, a massive global ecosystem. This allows the lock to trigger other smart home devices (like turning on lights when you unlock the door). More importantly, the Mercury X6 acts as a video doorbell. When someone presses the bell, you receive a video call on your phone, allowing you to see and speak to the visitor before granting access.
Door and Gate Bundle Ecosystem (Singapore Context)
In Singapore, most HDB and many Condo units have a metal gate in front of the wooden door. Both locks excel here:
-
Solity Setup: Pairing the GP6000 with the GD65B gate lock allows for "Dual Unlocking." Unlocking the gate can automatically trigger the door lock to open.
-
Mercury Setup: The Mercury X6 + G3 Gate Lock bundle offers a unified experience. The G3 gate lock also features cameras and biometrics, ensuring your entire entrance is monitored and synchronised within one app.
Design and Everyday Convenience
The GP6000 features a classic, robust push-pull design that feels substantial and premium. It is built for durability and long-term mechanical use.
The Mercury X6 features a slimmer, more modern aesthetic. Its convenience lies in its "visitor awareness." You no longer need to walk to the door to see who is outside; you can check the indoor screen or your phone. This is a game-changer for large families or those who receive frequent deliveries.
Who Should Choose the Solity GP6000?
You should choose the Solity GP6000 if:
- You want a trusted Korean-made brand with a proven track record.
- You prefer using fingerprints as your primary way of entering.
- You want a simple and easy lock without video or intercom features.
- You already own or plan to buy other Solity products.
Who Should Choose the Interlock Mercury X6?
You should choose the Interlock Mercury X6 if:
- You want the most advanced biometrics (Face & Palm Vein) available.
- You want to replace your traditional peephole with a digital video viewer.
- You need to see and talk to visitors remotely via your smartphone.
- You want to integrate your lock into a broader Tuya smart home setup.
Final Verdict
The Solity GP6000 is a "powerhouse" biometric lock—it does the basics of locking and unlocking better and faster than almost anyone else. It is a reliable, high-quality choice for any Singaporean home.
However, the Interlock Mercury X6 is more than just a lock; it is a security hub. By combining high-end biometrics with a video intercom and a built-in camera, it offers a level of safety and convenience that the GP6000 simply isn't designed to provide. For a modern, tech-forward home, the Mercury X6 is the superior choice.
