CCTV not working? Troubleshooting and support in Singapore

Most CCTV faults come down to four things: a full or failed hard disk, a loose cable or power supply, a lost internet connection, or a changed password. Check those first with the steps below. If your system is still not recording, a camera is offline or you want a check-up, contact CCTVSG.NET and we will help.

How does remote support work?

Many internet and app problems can be fixed without a visit. You run a remote-support tool on a computer that is on the same network as your CCTV, and our technician connects and checks the settings with you watching. Our remote support page has the steps.

How do you keep a system healthy?

  • Check once a month that every camera shows a picture and that playback works
  • Wipe dome covers and lenses, especially outdoors
  • Confirm the date and time on the recorder are right
  • Change default passwords, and update them when staff leave
  • Replace a hard disk that reports errors before it fails

When is it time to replace instead of repair?

When the recorder no longer gets app updates, when several cameras have failed, or when the picture is too poor to identify anyone. Existing cabling can often be reused, which keeps the cost of an upgrade down.

Frequently asked questions

Do you support systems you did not install?

Send us the brand and model of the recorder and a description of the fault on WhatsApp, and we will tell you how we can help.

My Hik-Connect shows the device offline. What now?

Check the recorder's power and network cable, then follow our Hik-Connect offline guide.

I forgot my CCTV password. Can it be reset?

Yes, but the method depends on the brand and model. See our password guides, or contact us with the model number.

    Absolutely happy with the service! Prabu, the installer was patient and meticulous with the setup and he took the time to walk me through everything clearly. Richard, the sales coordinator, was friendly and very accommodating—he explained the different options at my budget without any pressure. Smooth, professional and trustworthy experience from start to finish. Highly recommended.
