Common causes
To better understand the technical aspects of the error, let's examine the specifications of a typical Hikvision NVR: hikvision maximum number of channels under playback reached
: If your system uses H.265, try switching to H.264 for specific channels. Some older hardware or mobile apps struggle with the processing power required for high-resolution H.265 playback. Common causes To better understand the technical aspects
| Device Type / Series | Max Simultaneous Playback Channels | Common Scenario | |----------------------|-------------------------------------|----------------| | Entry-level DVR (e.g., 7200 series) | 4 or 8 | Small office, retail store | | Mid-range NVR (e.g., 76xxNI-I series) | 16 | Warehouse, school campus | | High-performance NVR (e.g., 96xxNI-I series) | 32 or 64 | Large enterprise, casino | | iVMS-4200 Software (PC) | Limited by your GPU/CPU & license; often 16-36 | Multi-location businesses | | Hik-Connect Mobile App | Typically 16 | Remote users | 76xxNI-I series) | 16 | Warehouse
In network-based surveillance systems (NVRs), the available network bandwidth can also affect the number of channels that can be played back simultaneously. High-resolution cameras require more bandwidth for smooth playback, affecting the maximum number of channels.
Reviewing and optimizing the system's configuration, including video encoding settings and network parameters, may help maximize the number of playable channels.
