Document cameras are amazingly useful tools. These devices let users project the images of a wide variety of items using the video projector without first creating slides or photographs.
Since some businesses require their employees to travel frequently, they usually have only a few minutes for setup. For mobile workers to effectively use a document camera, it needs to be set up quickly, simple to operate, and very adaptable. Most importantly, the document camera should not be limited by the short cable connecting it to the projector.
The AverVision W30 addresses all of these problems. It is a wireless device, meaning it has a base station that connects to a monitor or projector. The camera has a rechargeable battery and can be placed anywhere within 45 feet of the base station. Users can adjust the camera to read documents, view small objects, or even use it with a microscope.
End-User Advantages
The W30 is easy to use. Once it’s set up, all that’s required is to turn it on. A fully charged camera will operate for eight hours. Because the camera is wireless and very portable, it can be used anywhere. The unit’s 30-characters-per-second frame rate supports motion-intensive apps, such as presentations.
One handy feature is that the device also works as a webcam, attaching to a computer through a USB port. Motion applications will work better and display little latency by choosing the “Motion” selection from the base station’s menu. The menu uses icons that are reasonably intuitive; these appear on the display (monitor or projector) that the user has attached to the camera.
Aver’s A+ Interactive software package, which comes bundled with the W30, adds to the functionality of the camera by supporting image capture, video capture and onscreen annotation of images. The W30 can also use USB or SD memory modules for saving images.
Why It Works for IT
The AverVision W30 requires little from the IT department. Setup is automatic once the base station and camera are plugged in and the camera is charged. When both devices are turned on, they automatically negotiate a connection via Wi-Fi, selecting a Wi-Fi channel that is least likely to cause interference. It’s worth noting that the Wi-Fi channel selected is not always one of the three standard 2.4-gigahertz channels. Testing for this review was conducted in a Wi-Fi environment in which all available 2.4GHz channels were already taken. As a result, the device selected nonstandard Channel 3.
While the use of nonstandard channels may cause interference under some circumstances, such problems were not noted during operational testing. Tests conducted with a Fluke AirCheck wireless network tester reported interference on Channel 1, but the W30 did not interfere with any devices on that channel. Users can try to get the device to choose a new channel by pressing the “Reconnect” button located on the base station. This will cause the base station to renegotiate the channel selection, but it does not guarantee that it will choose a different channel. Odds are, users won’t have to deal with conflicting Wi-Fi networks, but the IT staff should be aware of the channel issue and be prepared to manage it properly.
Disadvantages
The AverVision W30 does not include an HDMI port, which means that using a modern high-definition display may require an adapter for the DVI port. While such adapters are available, they don’t always work with all displays.
