Yes they are. The ATEM Television Production Studio is an entry level hardware piece that, as per it's name, takes the place of an actual TV studio. The only thing to keep in mind when setting up your ATEM is that you will not get an image out of the device if the resolution and framerate settings are not the same on both your camera, and your ATEM. 

Once you get your ATEM switcher, plug it into power, plug it into your network with a standard cat5e cable, and then plug in a USB cable from the USB 2.0 prog connection on your ATEM device to your PC. Next, go to download the newest software for your device available from BlackMagic Design ( Once you get the newest version of ATEM switchers update, go into your start menu, then all programs, and then BlackMagic Design. You should then be able to go to ATEM switchers and run the ATEM setup utility. 

As long as your device is connected to your PC with a USB cable, you should be able to see your devices IP address. Keep that open, and go into your BlackMagic Design All programs folder, and run your ATEM Control Software. You should be prompted to put you your IP address, just use all the information from the ATEM setup utility and connect to your device. 

You should now be seeing a switcher interface. This is how you control your ATEM Television Studio. You should now be able to adjust your switcher settings. First, go to the "gear" in the bottom left. 

Now you should get an option to set your Video Standard. 

The PTZ Optics cameras will pull through if you set that to 1080i50, or 720p50, but the cameras rotary dial on the back has to be changed to match. If you choose 1080i50, please set the rotary dial on the back of the camera to 3, and if you want 720p50, choose dial setting 5. Be sure to power cycle your camera after each rotary dial change. 

You should be able to now connect your cameras and get a video feed. If you are connecting to inputs 3 or 4, you would need to go to your input labels page, and select whether you want those inputs to be SDI or HDMI.

At this point, you would need to hook up the Multiview output of your  ATEM to a monitor or TV. Once this is done you should be all setup and viewing your camera feeds.

Here is an example I have of 2 PTZ Optics cameras each feeding an HDMI and an SDI input on the ATEM.
