PTZ Optics PT20X SDI-GY-G2-20X Optical Zoom Broadcast and Conference Camera 3G-SDI, HDMI, IP

Product Information

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! 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. Step 2 – Find a level location and tape the calibration sheet to the wall 1 meter from the camera lens. This onboard streaming encoder can encode two data streams to the cloud at once (though you need to drop down to 30fps). In addition, you have SDI and HDMI out, so you can operate in pretty much any creative environment, taking audio via the 3.5mm stereo line input if needed for convenient encoding. H.264 and H.265 with AAC, MP3 or PCM audio are all on offer, from 16KHz to 48KHz.

Sure, UHD (4K) adds a bit to the price compared to the, but the low-light quality the large (1/1.8-inch) Sony sensor achieves and the very long zoom range makes this a sensible choice. Studios will appreciate that all the desirable connectivity, as well as tally lights, are there too. Wide Dynamic Range: Helps with challenging lighting conditions such as a mix of dark and light areas 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? PTZOptics has several ways you can reach us if you have any questions about your production project. Connect with us via: The main disadvantage is that you are magnifying pixels to accomplish digital zoom. This results in reduced resolution. For example, a 4K video camera digitally zoomed in at 3x, results in a final video resolution of only 720p (a loss of total resolution of 88.9%). This is a very significant reduction in resolution and image quality. Therefore, you need to consider your application and its needs before deciding whether ePTZ can work in your application or you should instead invest in a true PTZ camera. One simple example would be if your streaming output or final file resolution is only going to be 720p, then a 4K camera with ePTZ limited to 3x will be sufficient, as the higher resolution is not required in the final product. EPTZ vs True PTZx 1080 @ 60 fps); Medium (1920 x 1080 @ 30 fps); Low (1280 x 720 @ 60 fps); Low Bandwidth (640 x 360 @ 30 fps) 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. Perfect for a conference room of about 20 people, or perhaps a classroom, the Logitech PTZ Pro 2 Video Conference camera plugs into your computer’s USB (Mac or Windows) via the generous 10-foot (3m) cable and provides a more flexible and (probably) better quality alternative than the system camera you’re used to.

With robust warranties included standard on every product, you can trust PTZOptics solutions to deliver high performance from day one, and for many years to follow. 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 ability to control PTZOptics cameras with an included IR remote control, a smartphone app, or your favorite video production software makes capturing the moment easier. Designed to make broadcast quality affordable. PTZOptics cameras put you in control of your next video production. 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.

PTZ cameras come with motorized stands which allow for remote control, AI automatic operation, or both. Their popularity has boomed in recent years, and that's no surprise. Almost any scenario where a webcam can be useful, including Zoom calls with presentations and streaming content on social media, can benefit from a camera that can follow you –especially if you like to use the whole space. The wide-angle field of view (74.1˚ horizontal at the wide end) means smaller venues aren’t an issue, and there's a variety of control systems. Its near-silent motor system genuinely impresses with its subtlety. And the dark UI makes operating the camera from the web interface without distraction practical. PTZ stands for Pan-Tilt-Zoom. It is taken to mean a camera which has motors so can remotely be told to Pan (turn left and right), Tilt (turn up and down) and Zoom on a subject. Do all PTZ cameras have an optical zoom? Maximum Cameras: 255 total cameras (28 cameras (4 groups of 7 channels) plus a group with up to 227 cameras) PT12X-ZCAM,PT20X-ZCAM,PT12X-SDI-xx-G2, PT20X-SDI-xx-G2,PT30X-SDI-xx-G2, PT12X-USB-xx-G2, PT20X-USB-xx-G2, (NDI Models also supported)The zoom isn’t as long as some cameras here, and Sony’s digital system –‘Clear Image Zoom Technology’– extends it, without abandoning quality, to 24x in HD or 18x in 4K. On the plus side, the camera is good in low light and has a menu-switchable ND filter. 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. The SRG-300H is an excellent camera with one of Sony’s EXMOR sensors, operable in light down to 1.4 LUX (f/1.6). This offers a wide dynamic range and, paired with Sony’s XDNR digital noise reduction and 30x optical zoom, produces great streaming-friendly video. 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.
