Now that our casino is installing a VMS/NVR system capable of handling modern IP cameras, I'm looking for suggestions regarding which megapixel cameras to test. Limitations imposed by the VMS and our choice of auxilliary equipment require that each camera be capable of delivering two 30fps HD/megapixel streams: one TCP/IP stream for recording and one Multicast stream for viewing. Cameras must also be ONVIF-compliant since we chose not to purchase "camera gateways" that can utilize cameras' direct streams.
We tested a few third party IP dome cameras earlier this year in conjunction with the VMS manufacturer's evaluation system and found that none could deliver two simultaneous 30fps streams. This included Axis M3000 and P3300 series and Ganz PixelPro series. Typical frame rates dropped to the 20-22fps range or lower when a second HD/MP stream was enabled.
I would appreciate any recommendations of cameras that will meet our requirements. The Axis P3300 series cameras provided the most pleasing images but they only provided ~22fps @ 2x720p streams.
