Replacing a Dahua CCTV system in a shop or office

If your shop or office runs an older Dahua system, you can usually keep the cabling and change only the recorder and cameras. A replacement Hikvision system with four cameras, recorder and 1TB hard disk costs S$639 to S$899, and a four-camera 4MP Uniview system costs S$1,069. We no longer supply Dahua, so replacements are Hikvision or Uniview.

What can be reused from a Dahua system?

Usually more than owners expect. This is what we check before quoting.

What can be reused
Existing itemReusable?Note
Coaxial cableUsuallyWorks with a Hikvision DVR system
Network cableUsuallyWorks with any IP camera and NVR
Dahua IP camerasSometimesMay join a new NVR through ONVIF; we test first
Dahua recorderRarely worth itReplace it when it no longer gets updates
Hard diskSometimesOnly if it is a healthy surveillance disk

How do you keep recording during the change?

Tell us your opening hours. For a small shop the old recorder stays running until the new one is ready, and the cameras are moved across one at a time, so the gap in coverage is short.

What about the old footage?

Footage stays on the old recorder's hard disk. If you need to keep any of it, export the clips before the old recorder is removed; we can show you how.

Frequently asked questions

Do I have to replace everything at once?

No. You can replace the recorder first and the cameras later, as long as they are compatible. We will tell you which combinations work.

Will staff need a new app?

Yes. Hikvision systems use Hik-Connect in place of Dahua's DMSS.

What does a standard installation include?

A standard installation runs the cable in surface trunking and mounts the camera on a wall or ceiling up to 3 metres high. Concealed wiring, new power points or higher ceilings need a site survey first.

    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.

    We recently upgraded our security system with cctvsg , and the experience has been exceptional. Mr Damon and cctvsg team was incredibly responsive, taking the time to understand our specific needs and recommending the best solutions. The CCTV cameras provide clear, reliable footage, and we now have complete peace of mind knowing that our property is secure!
