Page 238DVR/NVR OverviewThis section answers basic questions about the use of DVR/NVRs and CCTV cameras withACS5000 and IPDC.How is video integrated with ACS WebService?The primary integration between your DVR and ACS WebService is via the Activity Log,which allows you to retrieve a video segment related to a specific event. (See Viewing Videobelow).From the Activity Log, ACS WebService uses the time stamp of each event to query theDVR/NVR. It also uses the configuration data supplied on the DVR/NVRs page to determinewhich camera is associated with an event, via the door or device at which the event tookplace. The DVR/NVR then returns the requested video stream for the time and cameraindicated, and plays it in a popup window.Throughout this entire process, the video images are streamed directly from the DVR toyour browser; they do not pass through Brivo’s network, nor is any of your video datastored on Brivo’s servers. The ACS WebService simply acts as a “directory” for associatingevents in your Activity Log with specific DVR/NVRs, cameras, and time periods.What types of devices can be integrated with video?ACS WebService treats both doors and inputs as special cases of devices; for example, anauxiliary input on a Door Board, or an input on an Input/Output board. All of these devicetypes can be associated with a camera for the sake of providing a link between events inthe Activity Log and video segments stored on the DVR/NVR.Can I configure my DVR/NVR from ACS WebService?The ACS WebService interface to your DVR is not intended to replace the native interfaceprovided by the DVR/NVR itself. Thus, all DVR/NVR configuration is still performed via themanufacturer’s configuration tools.By the same token, the ACS WebService interface does not disable or change any of theexisting viewing tools provided with your DVR/NVR. These tools may offer a different rangeof viewing options from the ACS WebService interface, and the two should be seen ascomplementary, and used accordingly.Which Brivo products will integrate with DVR/NVRs?The DVR/NVR integration feature works with any ACS4000, ACS5000 or IPDC series controlpanel.Which DVR/NVR products are supported?Brivo is integrating a growing list of DVR/NVRs with ACS WebService.
