Third party compatibility issues with DH Vision products

Third party compatibility issues with DH Vision products

Compatibility issues can occur when using third party video recorders and network cameras with Dahua OEM products, however it is typically rare with analog products.

Here are a few things to keep in mind:

  • Dahua's network camera compatibility list can be found here.
  • When testing for compatibility, make sure that all devices are up-to-date with the newest firmware available.  To ensure Onvif compatibility, the video recorder Onvif version must be the same or newer than the network camera (due to backwards compatibility).
  • If a third party network camera firmware has not been updated for over half a year, there is a good chance it will not be Onvif compatible with up-to-date Dahua video recorders.
  • Onvif compatibility usually ensures video stream but does not necessarily guarantee other features such as event linking (motion detect and alarm).  Test products thoroughly to confirm if they will meet specification.
  • Some third party cameras have an Onvif option that is not enabled by default.  Access the camera’s web configuration and enable the Onvif option if available.
  • If a camera connects but displays a blank or white video stream:

◦     Check the video compression on both the network IP camera and the network video recorder. 
◦     Some cameras only support MJPEG and there can be issues with MJPEG cameras and Dahua compatibility even when both devices are Onvif compatible. 
◦     Since encode settings do not synchronize between Dahua and third party products, make sure the encode settings match on both devices while troubleshooting. 
◦     Try using 9988 as the HTTP port when remotely adding the camera as Onvif (Dahua recorder). 
◦     Try adding the third party network IP camera as Private.
◦     If troubleshooting does not correct the issue, there may be some underlying install or compatibility issue that is not resolved by protocol alone. 

  • Currently Dahua video recorders and software do not support dewarping for fisheye cameras. 
  • Due to the overwhelming number of POS systems, POS integration with Dahua units requires extensive testing to verify compatibility as well as the proper connection (RS232 or Network ).
  • Typically, alarm systems should integrate so long as the proper connections are available (RS485).

Be aware that DH Vision products may not be compatible with the third party products intended to be integrated.  Explain job specifications to a sales representative before committing to a product.  Testing compatibility beforehand can save time and money, even if compatibility is assured or assumed.
