Recommended cameras for streaming on Ustream

A typical setup for streaming involves up to three components:

  1. Cameras
  2. Capture
  3. Encoding

There are hundreds of different cameras that will work with Ustream. In terms of compatibility with Ustream, what's important is not usually the specific brand and model, but rather the type of output your camera has and how that connects to your encoding software or hardware. Most cameras do not connect directly to Ustream, most cameras you will need to connect to a switcher, capture card or encoder and the encoder is what sends the video stream to Ustream.

Please see recommended streaming setups to find out which encoders we recommend.

There are several types of cameras that are the most commonly used and the easiest to use for streaming to Ustream:

  1. Built in webcams or USB connected cameras
  2. HDMI cameras
  3. SDI cameras
  4. Component or composite (analog) output cameras
  5. Cameras with wi-fi capability and direct connection to Ustream

Many cameras may be capable of multiple output types. For example, your camera may be able to output both analog component and HDMI output.

 

Built in webcams and USB connected cameras

If you use our Web Broadcaster or Ustream Producer, both of these encoding programs should autmatically recognize your built-in webcam or any USB-connected cameras. Our favorite USB camera is the Logitech C920. This camera usually costs less than $100 USD and has great HD quality.

Pros and Cons of Built-in / USB webcams

Pros
Low cost
Easy or no setup involved
Can connect directly to most computers, no capture cards or boxes required
Usually no batteries or AC power required, can be powered directly from computer
Cons
Typically lack zoom, manual focus, iris, white balance and gain controls required for more precise shots
No ability to upgrade lenses
No ability to record locally
No ability to input professional audio and pass through to encoder

 

HDMI cameras

Cameras with HDMI output are a great choice because there are many inexpensive models available that shoot and record in HD and output over HDMI. Click here to shop for cameras currently available at B&H Photo/Video with HDMI output.

These types of cameras can be used with an HDMI capture card or box, our current favorite is the Blackmagic Design Intensity Extreme Thunderbolt, going into Ustream Producer.

Another option for HDMI cameras is the Teradek VidiU. This portable encoder allows you to stream from any HDMI camera over 4G, WiFi or Ethernet.

Pros and Cons of HDMI Cameras

Pros
Wide range of options, from affordable entry-level camcorders to professional, full-featured cameras
Widely available and easy to buy
Easy to convert to SDI for more capture / encoder options
Cons
Might require conversion to SDI for compatibility with some switchers and encoders
Cannot do cable runs as long as SDI
Cables do not lock, can get disconnected if you are not careful
Some consumer-level HDMI connections have built in copy protection which will prevent signal transfer

 

SDI output cameras

SDI output cameras are the most professional, and typically the most expensive option. SDI cameras are common in professional video productions because SDI cables lock into place, offering a secure connection. In addition SDI cables are the best for long cable runs. With USB, Analog and HDMI cables you can only go about 20 feet (maybe up to 50 feet in ideal conditions) before you start to run the risk of video image quality loss or interference. With SDI cables, you can do much longer cable runs without fear of interference. Because cameras with direct SDI output can be expensive, many people choose to use HDMI ouput cameras and then use an HDMI to SDI converter. An HDMI cable can run out of the camera into a converter which is located on the tripod of the camera, or right near it. This way you only have a short HDMI cable run out of the camera and then from the converter to your switcher or encoder you can run SDI cable.

Pros and Cons of SDI Cameras

Pros
Most professional and robust connection type
Can do the longest cable runs
Locking connectors
Most common connection type for capture cards and encoders
Cons
Cost

 

Component or composite (analog) output cameras

Most cameras have some option for analog output. Typically it is a proprietary connector type on the camera end and a standard "RCA" type connection on the other end of the cable. Many switchers and capture cards accept analog connections, so these can be a good choice for maximum compatibility. The downside on analog cables is that you run a higher risk of interference or video quality loss, the longer you run the cables. Using high quality shielded cables and keeping your cable runs short can help avoid this.

Pros and Cons of analog cameras

Pros
Very common connection type, available on almost any camera, new or old
Lowest cost, particularly with all the older used cameras available
Easy to source and replace cables and cameras
Relatively easy to find capture cards, switchers and encoders that support this connection type
Cons
Many analog connections only support SD resolution. Only newer cameras support HD over analog component connections
Not recommended for long cable runs. Analog cables can be prone to interference and signal degredation.
Most camera brands have proprietary connectors on the camera, these cables are not as easy to replace and typically you need to connect an additional cable to reach your switcher or encoder

 

Wi-Fi Cameras with Direct Ustream Connection

Several manufacturers have cameras available with a direct connection to Ustream via on-board wi-fi on the camera. The main advantage with these cameras is that no additional computer or encoder is necessary to stream to Ustream.
