From a single device to a whole office, all handled the same way
A chemical plants client working in Jinshan Industrial Zone 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.
A machining factories client in Shanyang 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.
What you most want to know about on-site service in Jinshanwei
No. On-site work starts by looking at the existing structure and bandwidth, and we schedule the switch after hours or on weekends, testing each part before handover.
Access runs over an encrypted tunnel, permissions are tiered by role, access is logged, and anomalous logins trigger alerts. Data never sits on third-party platforms — it stays on your own equipment.
Up to 10 users generally from RMB 1500, 10–50 users from RMB 3000, and multi-site by site count. We assess your network for free and give you a plan and quote to confirm.
Connection, speed and permission issues can usually be fixed remotely, from RMB 200/visit; annual-maintenance clients get support within the agreed scope.
Most cases just need one access device on the existing network; we assess first.
No — accounts are revoked the same day per process, with auditable access records.
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.
