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

Product Information

If you want a camera with a full range of connectivity and remote control options, including iOS and Android apps, the PTZ Optics SDI series (also available with 20x and 30x lenses) is the ideal choice. When you reach out to PTZOptics for support, you won’t get an automated system — you’ll get a team of in-house, US-based experts ready to help. 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 PTZPerfect 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. 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!

NDI ® is a brand of the Vizrt Group and a royalty-free technology that allows video and audio sources to be shared bi-directionally across a network, eliminating the need for costly direct connections, expensive cable runs, and infrastructure upgrades while turning every source into a destination instantly available anywhere on the network. From integrated PTZ camera controls inside Ableton (and other DAW software) to MIDI camera control, PTZOptics has worked with our customers to build the integrations that work for House of Worship. Keys Vineyard Community Church’s live streaming and video production setup takes advantage of Ableton’s touch screen control software called TouchOSC, which allows media coordinator Doug Lawes to automate the entire church video production system. 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. All our PTZ cameras feature SDI, HDMI, NDI ®, multiple standard IP streaming formats. They’re also equipped with the latest professional camera control technologies, making remote operation easy.If you’re a vlogger who has invested in a good quality phone, but doesn’t quite have the budget for a production assistant or camera operator, the Obsbot Me is the solution; it turns your phone into a camera which can follow you. OK, not strictly meeting the tilt and zoom criteria (though there is always post-production), but this is still a very handy tool for to-camera shots. 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. 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. It does have a few, so long as the above requirements are first met. An ePTZ camera has the ‘magical’ ability to move instantaneously to a new shot (via a called preset or a direct PTZ position command). This can be very useful for some applications. There is absolutely no wait for framing the new shot. With a true PTZ camera, you will have to wait for the mechanical motors to move to the new P, T and Z positions. However, the disadvantage of this is that with most (if not all) modern ePTZ cameras, you simply cannot produce a panning, tilting or zooming sequence without physically moving the camera through space. As ePTZ technology develops, we will likely see ePTZ panning tilting and zooming sequences become available to better emulate the capabilities of a true PTZ camera.

This offers a wide dynamic range and, paired with Sony’s XDNR digital noise reduction and 30x optical zoom, produces great streaming-friendly video. For example, I have CDN URL: rtmp://my.cdn.com/live1 and I have a stream key: xyzabc123. To stream from the camera, I must enter the following into the RTMP(S) settings: “rtmp://my.cdn.com/live1/xyaabc123”.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.

ePTZ uses the technology of digital zoom to provide true PTZ-like features on a fixed (non-PTZ) camera. Digital Zoom works by simply magnifying pixels. When you do this, you are essentially focusing only on a portion of the entire camera image at any given time and magnifying it to fill the entire frame. Since you are only viewing a portion of the image at any given time, you can now move that ‘area of interest’ across the entire camera image to affect a pan and tilt effect (without moving the camera head). So digital zoom not only allows you to ‘zoom’ in on an image but also to move around within that image when zoomed. Wide Dynamic Range: Helps with challenging lighting conditions such as a mix of dark and light areas Maximum Cameras: 255 total cameras (28 cameras (4 groups of 7 channels) plus a group with up to 227 cameras) 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? Our plug-and-play USB 3.0 camera models are built with ease of use and compatibility in mind, featuring game-changing optics and video communication installation options.PTZOptics has several ways you can reach us if you have any questions about your production project. Connect with us via: 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. Control Protocols: VISCA over IP (PTZOptics & Sony) or Serial Control (RS232, RS485, Pelco-D, & Pelco-P) 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. 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.
