As with any other IP camera, I would like to know if these PTZs can provide two simultaneous 30fps streams: one TCP/IP Unicast and one Multicast. We are currently testing IndigoVision PTZs but have yet to compare other IP PTZs to our existing analog Pelco Spectra II, III and IV fed via encoders.
In that vein, if anyone has suggestions for IP PTZs that fit our requirements, including Axis, I would love to hear them. The Pelco Spectras aren't performing as we would like. There appears to be a problem with low light sensitivity. Pelco's AGC increases the noise and the encoders compound that by making the picture "muddy". We have changed the AGC limit in the Spectras to 10db and that improved the image but also made it darker and the cameras' lenses often auto-open the iris fully. Some switch to monochrome regularly due to not having capability to disable day/night switching. That is a function of model and firmware version.
Carl, Axis claims multistreaming has been improved with this new series: "The new AXIS Q60 cameras are equipped with a powerful CPU (central processing unit) and co-processor. They .... provide improved support for simultaneous streaming of multiple individually optimized video streams"
Also, related, Axis has announced their ARTPEC-5 chip which claims improved multistreaming as well. I would expect to see this chip in an increasing number of new Axis professional releases, both PTZ and fixed.
Thanks John. Good to know. We have a standing invitation from Axis to evaluate their cameras but discovered in our original tests of P and M series fixed cameras that they were unable to provide two simultaneous 30fps streams. On the plus side, their image quality was the best of any camera we tested, especially in low light (something many casinos suffer from). If that translates to their PTZs, it may be a solution.
