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
