Chapter 2 About NiagaraAX Video Integration
The NiagaraAX Video Framework module (videoDriver) provides the foundation for integration to selected Commercial Off-The-Shelf (COTS) video surveillance and recording systems so that all normal daily operations can be performed from a NiagaraAX application interface. Video Framework provides performance enhancements for both users and developers.
Video integration is accomplished by modeling the commonly-used video functions in the NiagaraAX Framework and using specific drivers for the different manufacturers’ video products.
Figure 3 Video networks and devices diagram
A unique video network for each family (manufacturer) of devices exists under the Drivers node.
Under an individual network are located:
- Digital Video Recorders (DVRs) or Network Video Recorders (NVRs) to which cameras and a display may be connected.
- Cameras directly connected to the network (no recording capability)
- cameras that include a DVR
- A computer and monitor connected to the network running NiagaraAX and configured to display multiple video feeds on the monitor
For protocols that support stand-alone cameras, cameras may exist directly in the root of the video network.
Video drivers have some properties and extensions in common with other ‟field bus” type network drivers. However, there are several distinctive characteristics that are described in the following sections:
