Once you know the feature, check if your device (camera, NVR, or DVR) actually supports it. Not all Hikvision devices are created equal. Features like VCA, smart event search, and advanced playback are typically found on mid-to-high range professional models, often in their "Pro" series or newer lines. Check your device's datasheet on the Hikvision website.

model. If it's fixed, the software is simply telling you it can't move that hardware. 2. Adjust Stream and Recording Settings
The Hikvision error code indicates a "Not Supported" action or command within Hikvision software ecosystems like iVMS-4200, iVMS-4200 PC-NVR, or custom platforms built on the Hikvision Network SDK . It surfaces when a user attempts an incompatible operation—such as applying advanced Video Content Analysis (VCA) templates to hardware lacking those capabilities or pushing unsupported resolution frameworks directly to a device. Resolving this bottleneck requires adjusting configuration templates, aligning video streams, and modernizing device firmware. Core Technical Drivers Behind Error 23
