Huaxin Town, Qingpu, Jiananxiaoqu. 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.

Remote access configured on the router and on your phone, so you can check the site from anywhere.

Old analogue systems upgraded to IP with more storage and smarter detection, keeping usable cameras.
Book nowDisk health, recording schedule and channel settings come first. A failing disk is far more common than a dead NVR.
Lens cleaned and refocused; a water-fogged dome or a failing sensor is replaced.
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.
Cable routing, earthing and power are checked, with separate runs where needed.
Seals replaced and the mount repositioned so it stops taking water.
Final cost follows the itemised quote on site. Nothing starts without your yes
