From a single device to a whole office, all handled the same way

A international schools client in Zhangjiang Hi-Tech Park had a device go down suddenly. We judged the fault direction by phone, and our technician brought matching parts and completed repair and testing the same day.

The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.

The client moved into a new office in Zhangjiang Hi-Tech Park, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.

The same problem had been handled twice elsewhere without a fix. We re-diagnosed to find the real cause, and after repair it stayed stable for a week of observation.

The client needed to operate normally during the day, so we came after hours. Several staff worked in parallel and finished testing and cleanup before closing.

A financial institutions client working in Kangqiao had devices failing and holding up progress. We visited by appointment and handled them in groups, restoring normal use the same day and logging the devices into a table.
What you most want to know about on-site service in Pudong
Most logical-fault drives can; clicking drives should be replaced and backed up first.
Set up automatic local plus off-site backups — a few hundred RMB covers most risks.
It depends on the number of points and equipment. A small shop with 4–8 channels is usually a few thousand RMB; offices and plants are priced by points and cabling difficulty. The survey is free — we give you a plan and budget first.
As fast as 30 minutes if close and traffic is light, most jobs scheduled the same day. Survey is free and there's no charge if you don't like the plan.
Yes. We use low-light or infrared models and add lighting if needed, adjusting angle and focus to the actual light, and verify night performance at acceptance.
Yes. After install we configure phone and PC viewing, a unified platform for multiple stores, and role-based access.
Describe the device and the symptoms; our technician brings the right tools and common parts. Diagnose first, quote after, and repair only once you approve.
