Company — Factory
One floor,
every fixture.
D.F.S production runs from a 10,000 m² facility in Xixiang, Bao'an, Shenzhen — joined in 2023 by a manufacturing base in Jiangmen. When one team owns the factory and the design, quality control is not a department: it is the process.

Factory overview
Where retail security hardware is actually made.
The footprint
- Factory floor10,000 m² in Shenzhen
- Second baseJiangmen manufacturing base (since 2023)
- LocationQianwan Key & Core Technology Industrial Park, Xixiang, Bao'an, Shenzhen
- Enterprise levelNational high-tech enterprise certification (2013)
What runs inside
- Power-board SMT and assembly runs for alarm cables, adapters, locks and ESL tags.
- 100% functional testing of every finished unit before packing.
- Aging and pull-cycle testing for the moving parts — recoilers, cables, locks.
- ISO 9001 management system covering incoming materials to final inspection.
Production line
Four stations, no shortcuts.
D.F.S follows the industry-standard process chain for security electronics: SMT placement, assembly, 100% functional testing and aging. Nothing leaves the building without passing all four.
SMT Placement
Surface-mount placement for power boards and alarm electronics.
Assembly
Recoilers, springs, cables, grips and housings assembled to the fixture drawing.
100% Functional Test
Every unit is tested — alarm, charging output and mechanical function.
Aging Test
Industry-standard burn-in at 40–50 °C for 4–24 hours before packing.
Four-stage QC
Checked four times, shipped once.
Quality gates
- Incoming material inspection — raw materials verified against spec before production.
- In-process quality checks — production stages monitored to prevent defects.
- Final product testing — functional, safety and performance tests on finished products.
- Continuous improvement — quality data and customer feedback fed back into the process.
Why it matters in your store
- A cable that passed aging is a cable that will not die behind a demo counter.
- Recoilers are pull-tested on the line — 30,000+ pulls of rated life.
- ISO 9001 pins the system to written evidence, not to memory.
- Custom runs go through the very same four gates.
Quality benchmarks
Acceptance criteria, stated plainly.
The values below are industry-standard reference criteria for this product class. Tell us your own spec — we quote against it, run what you require, and document the result.
| Item | Industry-standard reference | Why it matters |
|---|---|---|
| Output ripple | ≤100 mV at full load | Clean 5V rail keeps alarm and charging stable. |
| Output voltage accuracy | ±1.0% | Device-safe charging for phones, tablets and watches. |
| Flame rating | UL94 V-0 housings | Plastic housings that self-extinguish. |
| Safety standard | IEC 62368-1 power chain | The global safety baseline for audio/video and IT equipment power. |
