Build an ONVIF conformant NVR or VMS without in-house ONVIF expertise. Our client software provides C APIs that convert and handle data between your client and ONVIF IP cameras, verifiable with the official ONVIF Client Test Tool.
Everything an NVR or VMS maker needs to talk to ONVIF cameras.
A reference procedure for calling ONVIF client service APIs: getting services, changing video encoder settings and more.

Lingo Client Procedure has been verified and tested via ONVIF with these cameras.
Implement the mandatory client features of the target profile, run the Client Test Tool against your NVR or VMS, fix failing features and generate the report. See the steps above.
No. Our C APIs handle the ONVIF data exchange between your NVR / VMS and IP cameras, and Lingo Client Procedure shows how to call each service.
