This year, a loyal JJR customer set up a personal studio. After completing the setup, they planned to replace the door lock with a smart lock. However, they hesitated for a while until a minor incident occurred a few days ago: while going downstairs to collect a package, they forgot their keys and were locked out in the cold hallway. Helplessly, they knocked on several neighbors' doors before borrowing a phone to contact family for assistance. After this experience, they decisively replaced the studio's lock with a smart lock.
Since both their home and their parents' house are already using JJR Smart Locks, they once again chose JJR and purchased the latest model, the JJR-2 Smart Lock. Below is my experience with it:
Selection and Installation
1. Selection Tips
When choosing a smart lock, be sure to verify the dimensions of the lock core in advance to avoid mismatches.
The JJR-2 Smart Lock package includes front and rear panels, a lock core, and related accessories.
2. Installation Experience
As a repeat installer of JJR Smart Locks, I am very satisfied with their service:
- The installation technician called in advance to confirm the address and model, arrived with all necessary tools, and carefully handled every detail.
- During installation, the technician noticed the door frame was tight at the top and took the initiative to make adjustments.
- After installation, the technician patiently explained how to use the lock.
The accessory design is also very user-friendly. For instance, the installation screws can be trimmed to fit the thickness of the door, reflecting JJR's professionalism and user-first philosophy.
Key Features of the JJR-2 Smart Lock
1. Security
- Dual-Chip Design:
- Both the front and rear panels are equipped with independent chips. Even if the front panel is damaged or malfunctions, the backup system in the rear panel can still operate normally.
- Grade C Solid Brass Lock Core:
It resists technical unlocking for up to 270 minutes, making it difficult for intruders to breach. Additionally, the lock sends real-time notifications of suspicious activity, allowing users to monitor and alert authorities via their smartphone.
2. Multiple Unlocking Methods
- Supports 12 Unlocking Methods, including:
- Fingerprint, 3D facial recognition, password, key card, palm vein, and more.
- Palm Vein Recognition:
Utilizes near-infrared scanning of deep vein patterns in the hand to unlock. This method is precise, secure, and requires no repeated input, making it especially suitable for elderly users and children.
3. Smart Ecosystem Integration
- Operable via WeChat Mini Programs and easily connects through Bluetooth for settings adjustments.
- Integrates with IoT Smart Home Ecosystems, compatible with Tmall Genie and Mi Home App, offering enhanced convenience for daily use.
4. High-Definition Video Monitoring

- Allows users to monitor the hallway in real time, even in dark environments.
- Supports remote video calls, enabling users to unlock the door for deliveries via their smartphone.
5. Long-Lasting Battery Life
- Equipped with a 5000mAh high-capacity lithium battery, which lasts approximately six months on a single charge.
In case of power depletion, it can be powered using a power bank for emergency unlocking or via a mechanical key.
Summary of Use
After using the JJR-2 Smart Lock for a period of time, I identified the following highlights:
1. Diverse Unlocking Methods: Palm vein recognition is particularly convenient and secure.
2. HD Camera with Large Display: Enables real-time monitoring of outside activity and supports video calls.
3. Dual-System Design: Ensures higher security with automatic notifications for unusual activities.
