PTZOptics PT20X overview

  • 1Description

This is the 20x-SDI Gen2 model of the PTZOptics lineup of advanced live streaming cameras, in gray, featuring a 3G-SDI output for connecting to switching equipment for broadcast conferencing. The Gen2 model is capable of 1080p60/50 recording (instead of a max of 30 fps), and streaming in H.265 and MJPEG in addition to H.264.

This camera has a 4.4 - 88.5mm lens providing a 20x zoom range, allowing for effective close-focus and wide-angle shots to best suit both face-to-face and group meetings. It does well in low-light conditions owing to a fast f/1.8 - f/2.8 lens aperture and minimum illumination requirement of only 0.5 lux at f/1.8. On top of this, built-in wide dynamic range and 2D and 3D noise cancellation further enhance the conferencing experience. The camera, along with its entire family of 20x and 12x models, is completely open source so developers can customize everything as they prefer using simple HTML commands.

In addition to the 3D-SDI output, the camera also has LAN, HDMI, and composite outputs, RS-232 input and output with daisy-chain capability, and an RS-485 port. The SDI, LAN, and HDMI outputs can be used simultaneously at the same resolution, which can be assigned via a dial on the rear. The composite output can only be used by itself and at 480i/576i resolution. The LAN output is capable of streaming two H.264 or two H.265 RTSP signals, one in HD and one in SD, or a single MJPEG signal, and allows for direct distribution to CDNs, streaming services, and other destinations using only the camera. There's also a 3.5mm audio input for embedding audio into an HDMI signal or LAN stream so you can deliver both audio and video to your destination. The LAN port can be used for streaming and control and also supports Power-over-Ethernet. As an alternative to direct streaming from the LAN port you can also connect external devices for more advanced conferencing. You'll also find a USB 2.0 port among all the connections, but this is strictly for firmware updates.

The camera can be controlled via the LAN port over a network, ONVIF over a network, and RS-232 via VISCA commands. RS-232 control includes control from any NewTek TriCaster, including any of the TriCaster Mini models. Simply connect multiple cameras to the TriCaster using DB9 cables and operate all of them from its software. A TriCaster can also be used over IP control using third-party software.

A large variety of software is supported, including most online meeting software, mobile apps for control over your network, and the advanced PTZOptics Network Control and VISCA Control applications.

An included IR remote control lets you adjust many settings via an on-screen display, allowing you to set and call presets, and control up to four cameras. You can set up to 64 presets in the camera (and up to 255 via RS-232), with a preset accuracy of 0.1°, and you can call up to 10 presets using the remote. The camera can be used desktop-mounted or ceiling-mounted, using an optional PTZOptics ceiling-mount bracket.

    PTZOptics PT20X reviews

    20x-SDI Gen2 Live Streaming Camera (Gray) is rated 4.3 out of 5 by 7.
    Rated 4 out of 5 by from Great Camera - needs up to date docs and some bugs fixed This camera has been great for our use in webcasting. It works very well with vMix. However, there are several bugs that need to be looked at in the camera, such as: not all configuration options show up via the web interface... many require the remote control, with an HDMI monitor connected to the camera to make changes or save changes. This is a problem if you are streaming via the ethernet port and the camera is 20' off the ground. The manual has not kept pace with the software either. Once I got past the configuration issues, etc., using the camera with vMix over ethernet has been excellent and produces excellent video.

    Rated 5 out of 5 by from Great camera for the price I used this product at a high school graduation this week as part of my two-camera live stream. It worked great. I was able to manage the entire production by myself with no problems. The camera delivered 720p video to my BlackMagic ATEM TVS with a good, crisp, clean signal, even when zoomed in completely on the podium at almost 100 feet away. I've used other remote-controlled broadcast cameras in the past... cameras that would cost 2x to 3x more than this camera, but if you are live streaming, this camera will look just as good as those.

    Rated 4 out of 5 by from Good, but be aware, non broadcast quality framerate Alot of equipment requires broadcast framerate of 29.97 or 59.94, these cameras are not capable of that.The workaround exists, but at a cost of $ per camera with MD-HX.

    Rated 3 out of 5 by from Blue hue comes across from a left when zoomed in I bought 3 of these and this is a problem on all 3 of mine. There is a blue hue that comes across from the left when zoomed into about 14x, and fills in the screen to about 3/4 of the way. I have a green stage and my color turn from dark green to light pale green. I am certain that this is a design defect with the lenses (lens is clean). Sadly, I will be returning these and going with a more expensive option.

    Rated 4 out of 5 by from Good but no no 29.97/59.94 and a bit much video latency Overall, this family of cameras is a very good value. The video quality (at this price) is very good. The build quality is great. The support is very good. I wish there were better color controls. I know they're not going look as good as my $5000 manually operated cameras in a multicam shoot but, if I could just tweak the colors a bit more, I would probably like the cuts between this camera and my "good" cameras better. I have 2 of these at my church (where we just use these cameras) hooked to an ATEM-TVS-HD. I was hoping to do 1080p but, because the ATEM wants 59.94 and this camera only does 60, I had to drop down to 720p30 (I think, I'm not there right now) to get the cameras and switcher to talk to each other. PTZO's solution ("we use a full frame sensor and can't do drop frame") is to use a decimator but, of course, I'd need one for each camera. I'm hoping an ATEM firmware update with eventually allow 60p compatibility with this camera. I've heard these cameras work great with the software based switchers (vMix, Wirecast, etc.) but I got an ATEM because it's less fussy to teach volunteers how to use a hardware switcher. That was before I realized there would be a drop frame incompatibility issue. The other issue is video latency. Since my audio is coming into the switcher via XLR (and not from the camera's audio jack/SDI), I was expecting a bit of lip sync issue. Turns out, the video is about 300ms behind the audio which was immediately obvious to most viewers. I added an audio delay to the input into the ATEM. I have an HDMI/USB version of this camera at work and have experienced the same thing there. At both places, I use a $10 iPad app to run the PTZ over the network (don't buy PTZOptics joystick, it's really not worth the price) and have been happy with the precision of preset recall and smoothness of motion. We sometimes do simple moving pan shots across the congregation or stage and, while not as good as moving shot from a good operator with a good tripod/head, they are quite passable for a basic church record/livestream. Overall, I'm very happy with these cameras but the "big brands" keep coming down in price so, unless PTZOptics addresses a couple of my concerns or drops their price, I may be buying Japanese next time.
