Huacao Town, Minhang, Xinchangjiayuan Community. No picture, black screen, no recording, offline on the app, night vision failed — describe what you see and we send the nearest engineer. We arrive with tools and common spare parts, diagnose first and quote before we touch anything.
Paying is fine. Not knowing what you are paying for is not. This is how we have always worked.
Power, cable, lens and IR board tested in order, so you know what actually failed.
Book now
Disk health and channel config checked first; corrupted playback is often a disk, not the recorder.
Book now
Cable runs are tested end to end. Most "broken cameras" are a bad termination.
Book now
New points cabled and aimed properly, including plate capture at entrances.
Book nowPower, PoE, cable and the camera itself are tested in order, so we replace the right thing.
Disk health, recording schedule and channel settings come first. A failing disk is far more common than a dead NVR.
IR board and power are tested. Under-powered runs are the usual cause.
P2P, router and account are checked; port mapping and mobile setup done for you.
Control line, power and the motor unit are tested before any replacement.
Cable routing, earthing and power are checked, with separate runs where needed.
