What are the limitations of Privacy overlay in BVMS 12 (Pano cameras, h.263 & MPEG, decoder, VSC)?

Question

What are the limitations of Privacy overlay in BVMS 12 (Panoramic cameras, h.263 & MPEG, decoder, VSC)?

Answer

Panoramic cameras

When Privacy overlay is enabled for panoramic camera, opening this camera in BVMS will result in no video and error message. (Possible improvement in future, with updated detector)

h.263 and MPEG

When Privacy overlay is enabled for h.263 or MPEG camera/ stream, opening it in BVMS will result in no video and error message

Decoder/ Monitor wall

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)

See chapter "decoders" within this lesson for details.

Mobile/ VSC

When Privacy overlay is enabled for a camera, opening it in Video Security Client or mobile App will result in no video 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

Please check the most up to date datasheet of BVMS for a list of supported GPU's in BVMS (in general w/o privacy overlay).

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
