Answer
When Privacy overlay is enabled for h.263 or MPEG camera/ stream, opening it in BVMS will result in no video and error message
When an user is trying to display on a decoder camera, where Privacy overlay is enabled, no video will be displayed (Workaround: in combination with CPP13 cameras, BVMS will only display on decoder stream with Privacy Protection enabled)
When Privacy overlay is enabled for a camera, opening it in Video Security Client or mobile App will result in no vide displayed
- Privacy overlay is not supported, when using DIVAR IP (AIO) as the Operator Client
- Privacy overlay can be used (enable feature license) in DIVAR IP (AIO) based systems, but only if it runs on a separate Operator Client workstation according to hardware and GPU specification.
- Privacy overlay is not available for BVMS Viewer
The following Nvidia cards are recommended to use for the privacy overlay feature:
- Nvidia Quadro P2000
- Nvidia Quadro P4000
- Nvidia Quadro RTX A2000
- Nvidia Quadro RTX 4000
- Nvidia Quadro P2200
- Nvidia Quadro T600
- Nvidia Quadro T1000
Performance limitations:
AI Performance indicates how many cameras can be processed simultaneously, with Privacy overlay enabled, on a single workstation, equipped with specific GPU.
Criteria:
- As a result of frames being dropped with workstation load, fps should not be lower than 20
- Applicable for resolutions from SD up to 5Mpx. In case of higher resolutions (4K) general decoding performance is a limiting factor
Some recommendations to get the pest performance:
- Ensure workstation with compatible and capable GPU
- Consider limitations for # of displayed cameras in system design
- Lowering down fps of displayed stream might give better results
