Zhongzhou Bay Shenzhen: Replacing Paper Patrol Sheets with Guard Tour System

A large mixed-use property replaced paper check-ins with tamper-proof patrol data, building a three-layer security system.

Zhongzhou Bay is a large mixed-use property in Shenzhen where security patrols directly affect resident safety and project quality. The estate previously relied on paper sign-in sheets: easy to alter or lose, impossible to verify, with proxy sign-ins and skipped rounds happening frequently.

Challenges

• Handwritten sign-ins could not prove patrols actually happened
• Managers had no way to know if guards missed, rushed or skipped rounds entirely
• A few guards even damaged readers on purpose to avoid patrol work

Solution

The estate deployed a full guard tour system — readers, checkpoints and management software — replacing paper entirely. Checkpoints were installed at corridors, commercial entrances, fire passages and other key positions; each guard carries a dedicated reader; routes and frequencies are preset in the backend. Guards tap each checkpoint along the route; readings are stored automatically. Hazards can be recorded with photos. After the round, the reader syncs all data to the backend — tamper-proof by design.

Results

• Each read stores its position and time automatically — no more altered handwritten logs
• The system generates patrol reports showing exactly when each guard reached each position
• Rugged readers with three-layer protection (waterproof, shockproof, dustproof) keep completion rates high
• A three-layer security system — human, technical and physical — now protects residents and facilities

Zhongzhou Bay replaced paper sign-ins with verifiable patrol data, solving proxy sign-ins and missed rounds at the root — a practical blueprint for large mixed-use properties.
