Dahua Replacement FAQs

Can I keep my Dahua cameras and coax wiring if I replace the DVR?

Absolutely! We have Avalonix DVRs that work with standard analog cameras and HDCVI cameras so replacing your recorder will allow you to reuse existing working cameras and cables without moving them. Provide the model numbers of your Dahua cameras and DVR to our support team ahead of time so we can ensure you purchase a compatible recorder.

Do I need to get a DVR or an NVR to replace my Dahua recorder?

If your existing setup uses coax cables connected directly to your recorder, you'll need a DVR. If your cameras connect using Ethernet cable, you will need an NVR.

Will audio from my Dahua cameras still work?

Yes. If you have Dahua IP cameras using Dahua's private protocol, they can communicate with our Avalonix NVRs and supported audio features will continue to work. Two-way audio will work as well on compatible cameras. If you have HDCVI coax cameras with audio, the audio signal will continue to travel over the coax cable to a compatible Avalonix DVR.

Will PTZ controls still work with my Dahua cameras?

Yes. Dahua IP PTZ cameras using Dahua's private protocol can communicate with our Avalonix NVRs, allowing PTZ controls to continue working. HDCVI PTZ cameras can also be controlled through a compatible Avalonix DVR, with PTZ commands traveling over the coax cable.

Will Smart Motion Detection and AI rules still work?

Yes, as long as the Avalonix NVR supports the function you intend to use. As a baseline, Avalonix NVRs support Smart Motion Detection, Tripwire, and Intrusion Box rules with compatible Dahua cameras. If you rely on a specific AI feature, provide us with your camera model numbers so we can confirm support before you order.

What do I need to look out for when upgrading my Dahua cameras and DVR to 4K?

You need to make sure the cameras, cabling, and recorder support 4K resolution. Just because you have a 4K monitor doesn't mean your equipment supports 4K cameras. We can recommend Avalonix cameras and a recorder that will work with your wiring and provide the video detail you are interested in.

When would I want to replace all of my Dahua equipment?

You may want to consider replacing your entire system with Avalonix equipment if you want to upgrade multiple cameras and the recorder. Let us know what areas of your property you want better video quality for and what features are important to you, such as audio or Smart Detection, and we can recommend cameras and a recorder that will work well together.
