Control Protocols: VISCA over IP (PTZOptics & Sony) or Serial Control (RS232, RS485, Pelco-D, & Pelco-P) If you want to zoom, you’ll probably want Sony’s FE PZ 28-135mm F4 G OSS (it has powred zoom). Sony takes pride in their web/tablet app, offering extensive control including programmed operation. In terms of operation, the app is not only easy to use and connect to standard streaming platforms (Facebook, Youtube, and RTMP), but offers extensive picture adjustments – either preset or manual. A paid subscription will allow you to stream to multiple platforms at once, and add live graphics. x 1080 @ 60 fps); Medium (1920 x 1080 @ 30 fps); Low (1280 x 720 @ 60 fps); Low Bandwidth (640 x 360 @ 30 fps) There is another intrinsic disadvantage to ePTZ here as well. Looking at the 4K ePTZ camera example above (today’s practical limit for available, affordable cameras), a 3x zoom will take you down by 88.9% to 720p (as mentioned above). However, even if 720p is acceptable for your final product resolution, you are limited to only 3x zoom to remain at 720p of higher. With true PTZ technology, you can get cameras with an optical zoom range from 3x all the way up to 30x optical zoom, without reducing your final product resolution by a single pixel. Again, your specific application will dictate whether ePTZ will suffice.
Understanding all of the impacts of ePTZ vs true PTZ and the specific needs of your application will help you to make the right choice when deciding between ePTZ, true PTZ or a combination of both technologies for your production. Dynamic range benefits from the Sony low-light friendly 2-megapixel image sensor (the benefits of higher resolutions aren’t always clear when zoom is used), while sound quality is an option in part left to you thanks to the ability to daisy chain speakerphones.
Our SDI line includes some of the most popular camera models we’ve ever made. With game-changing optics and high-quality video outputs, video professionals can create innovative custom systems to uniquely suit their needs. Take control of your PTZOptics cameras with our Open Broadcaster Plugin. The new plugin includes advanced features for pan, tilt and zoom control of your PTZOptics camera directly inside OBS! You can now copy the stream URL and the stream key into the RTMP streaming box on your PTZOptics camera in the Network Tab. This is done by entering the server and then entering a forward slash, followed by the stream key. No. The term PTZ is so well understood for remotely controlled cameras that, even where no zoom or a digital-only zoom is available, people often still refer to them as PTZ. On this list, for example, the Obsbot Tiny 2 has a digital zoom, though at least up until 2x you might not even spot it. What are PTZ cameras used for?
The ZCAMs have an issue with utilizing PoE and the SDI connection simultaneously. They must be powered with a PoE splitter when utilizing PoE and SDI at the same time. Another disadvantage of ePTZ vs true PTZ is the range of view. A true PTZ camera can often pan by as much as 340 degrees horizontally and tilt bay as much as 120 degrees vertically. This allows a single camera to cover a huge area of the local environment or ‘set’. An ePTZ camera, on the other hand, is limited to the field of view of its fixed lens and fixed camera head. This can typically range from 40 degrees to 110 degrees horizontally, with a common field of view being around 70 degrees (vs 340). Therefore a much larger quantity of ePTZ cameras will be required to cover the same ‘set’. As with resolution, an evaluation of your specific needs will determine whether ePTZ or true PTZ is a suitable choice for your application. Does ePTZ technology have any advantages?
