What is a PTZ camera?
A Pan/Tilt/Zoom (PTZ) camera operates with either a hardware and/or software remote control for panning, tilting and zooming. Oddly enough, some cameras can lack one of these features, like having a zoom, yet they are still called PTZ cameras. PTZs are often referred to by other names such as robotic cameras, conference cameras and robo cams.
What are some advantages of a PTZ camera?
- PTZ cameras allow one operator to control multiple cameras at the same time.
- PTZs can provide reliable control and smooth moves while broadcasting/streaming.
- PTZs can easily obtain great overhead shots.
- PTZ setup is quicker, and the camera may only require running one lightweight cable.
- PTZ cameras allow for a much smaller footprint since you can operate them remotely.
Who can benefit from a PTZ camera?
PTZ cameras provide great live shots due to their movement abilities and placement advantages. Because of this, it might be an optimal choice for applications like stage productions, corporate events, houses of worship and even outdoor productions. When using only PTZ presets with an IR remote, streaming can be ideal for use in classrooms, corporate or government boardrooms. Once a PTZ camera is installed and presets are programmed, that PTZ can be operated by someone with no technical skills. IR control is also great for cooking, crafting, or building overhead shots.
What to look for when buying a PTZ camera?
At first glance, it may seem like an easy task to choose the right PTZ camera for your productions. However, there are many variables to consider. Issues that are too difficult or time-consuming to change later should be a major consideration. This includes:
- Lack of direct streaming
- Lack of telephoto capability
- Noisy image
- The highlight/shadow/color of the PTZ doesn’t match the other cameras in use
You can address all of this by finding a camera that is well suited to your needs.
Is matching cameras important?
If you want to mix your PTZ with other cameras, you’ll want the color, highlight and shadow to match fairly well, or it will make for a jarring transition when you cut between cameras. Sometimes, focusing all of the cameras on the same white object and white balancing the cameras can be a simple solution. For greater accuracy, use a large chip chart — camera chart — to auto white balance. Then fine-tune the color, highlight and shadow with manual controls. Keep in mind that many lower-end PTZ cameras have no manual controls. This can make it impossible to match the PTZ camera with other cameras or even with other PTZ cameras. Additionally, using cameras with similarly sized image sensors will make things easier. For example, to match a 2/3-inch HD ENG camera to a PTZ, use ½-inch or 1-inch UHD PTZ cameras. UHD cameras tend to be easier to balance than HD cameras.
Why does sensor size matter?
Typically, the larger the image sensor on the camera, the less noticeable noise you’ll get in your video. Larger sensors also tend to have better color reproduction. This can allow you to gain up — amplify — the video from the camera in low light with less impact on image quality. The drawback to this is that larger sensors have a broader field of view. This can lead to the need for larger focal lengths. For example, a 1-inch sensor needs a 200 mm focal length lens to get roughly the same field of view as a ½ sensor with a 100 mm focal length.
What is the difference between optical and digital zoom?
Optical zooms use the camera lens to increase magnification, which has little effect on image quality. Digital zooms push in on the image and effectively reduce resolution causing the picture to look grainy. For example, if you have a 1920 x 1080 — HD — camera and use a 2x digital zoom, you’re now looking at a 960 x 540 image.
Why do some cameras list zoom speed?
Zoom speed is important if you want or need to change focal lengths rapidly. It seems that only the cameras with faster pan and zoom will list these speeds.
How do I determine how much zoom I really need?
To ensure that the zoom range — wide to telephoto — of your PTZ is adequate for your shooting location, you’ll need to have some idea of the types of shots you want.
“I want to explore all of my possibilities.”
Stand where you would like to install the PTZ, and using a camera that you already own, frame up the widest and tightest shots you think you’ll need, taking note of the focal length for each and changing lenses if necessary. Now, find the crop factor of the camera you just used. The crop factor is the sensor’s difference in size in relation to 35 mm still film — full-frame 35 mm. For example, Micro Four Thirds sensors have a 2X crop factor; so, if your shots were at 10 mm and 200 mm, this means the 35 mm equivalent to the zoom range you want is around 20 mm x 400 mm. It’s important to note that crop factors are often approximated to the actual image sensor size. To be safe, add a 20 percent cushion to your calculation which would bring the example above to be 16 mm x 480 mm. Now that you know the 35 mm equivalent zoom range, you’ll want to look for cameras that meet or exceed that requirement.
“I only care about headshots.”
For this, you can utilize a focal length equation to determine your lens needs. To do this, you will need to know the sensor size (horizontal), the distance to the subject and the Horizontal Field of View (HFOV) for your headshots. While the sensor size and distance to the subject are easy to determine, figuring out the HFOV takes a bit more work.
To get your HFOV:
- Stand in front of a mirror.
- Use a tape measure or yardstick and measure where you’d want to see your head framed. Think vertically, top to bottom of your eyes, above the head to mid-chest level or somewhere in between. Write down the metric measurement — convert if needed. Now, take that vertical measurement and multiply it by 1.78 (because 1.78:1 is the aspect ratio for HD/UHD, often called 16 x 9). This sum is your desired HFOV.
Now, use this formula to determine your required focal length:
- FL = focal length
- SS = sensor size — 36 mm for 35 mm equivalent or the actual camera sensor horizontal length
- D = distance to the subject
- HFOV = Horizontal field of view
What are my controllers’ options and considerations?
There are three basic types of controllers: hardware controllers, software controls and IR remotes. Let’s look at the advantages and disadvantages:
For the fastest, most accurate control while live, you’ll want one hardware controller and monitor per camera. The monitors should be placed directly behind the controllers for quick, easy reference. The monitor should be the same resolution as the camera to aid in manual focus and see what you are sending to the program — IMAG, record, stream, etc. A multi-view monitor makes it harder to see what camera you’re controlling. Additionally, if the camera windows drop below the camera’s resolution, it can make focus and other fine camera adjustments harder, if not impossible, to see.
Large hardware controllers can be used for multiple cameras and give you physical control over many camera settings making cameras easier to balance and set preset PTZ positions. They aren’t always as quick to control as having one controller per camera because you often have to select the camera before you can operate it.
Software controls are not ideal for moving pan/tilt/zoom while the camera is live. Software controls can give you complete manual control or no control to balance the camera(s). Additionally, Wi-Fi setups share the same chance of interference as most other wireless devices.
IR remotes are good if you’re in a small room and just switching between presets. When in a large room, it is also helpful to power up and check camera movement before your control cables are installed. The IR remote really isn’t a viable option for manual camera moves.
What about protocols?
If you’re working with existing hardware, software and networks, protocols can be critical. There are many different protocols utilized by PTZ cameras, such as NDI. The camera function isn’t affected by the protocol used. It’s only by what hardware and software you can use to alter the camera and streaming settings. Some cameras support multiple protocols; some protocols are used across different manufacturers, while some are unique to one specific brand.
What are important considerations for camera ports?
HDMI, SDI or high-quality streaming from the camera is necessary for better image quality for programs or recordings. While some PTZ cameras have SD slots, the compression used to record to the cards is often very high. The card function is better used as a backup if the record feed should falter. With this in mind, consider your production needs as we take a closer look at these common ports — and cables.
- SDI will often give you a video signal with less loss of color information and no image compression making the camera easier to balance. The cables are easy to run but don’t carry control or power.
- HDMI often carries less color information and no image compression. HDMI is limited to a 40-foot cable without amplification. It also doesn’t carry power or control.
- Wired Network (Cat 5, Cat 6, etc.) often compresses the image and decreases the color information to save on bandwidth. This makes camera balancing harder; however, higher and lower quality presets are often available. With PoE (Power over Ethernet) and IP streaming, one inexpensive cable can carry video, power and control at a distance of 300 feet. These cameras can often stream to a network with no other hardware. Check the camera specs because some network ports are for controls only when using a matching controller.
- USB often allows the camera to be recognized as a webcam by a computer; however, some only work with proprietary hardware or software. USB is limited in cable length without adapters but often carries power, video and control.
- RS-234, RS-485, etc. — these multi-pin ports are for control only. The cables can be fragile and expensive, making Cat 5 or higher network cable a better option unless no other control options are available. Cameras with these ports can sometimes be daisy-chained, but this is also not ideal because if the first camera in your chain goes down, you can lose control of all the cameras.
For the fastest setup and teardown of PTZs, you’ll want cameras with PoE and video over network cables paired with controller(s) that have video outputs if needed.
What is image flip, and do I really need it?
Inversion, ceiling mode and image flip allow upside-down video to appear right side up if the camera is mounted inverted. Even if your camera isn’t ceiling-mounted, mounting it upside down can make it easier to level, as most PTZ cameras don’t self-level.
Consider your options
There are a lot of options when shopping for a PTZ. Like cinema cameras, you should consider your entire production and post-production workflows, even your deliverables. You’re bound to make a great choice with all of this in mind.
