There is much variety in all kinds of consumer electronics today. Same is the case with conferencing cameras. While any regular webcam can give you what you need for your personal use, it is an entirely different kettle of fish if you want something far more advanced than just your basic camera. This post deals with what you should look for in a good video conferencing camera.
The performance of a conferencing camera is basically a complex combination of lens, resolution, color, noise and algorithms. You first have to understand the kinds of features each brand offers you, before making your final purchase.
- Quality of lens
The camera lens quality matters a great deal for capturing good images. If the lens is not compatible with the type of camera being used, the result is distorted images. Test your device before purchase to ensure that your camera lens does not distort images in any way.
- Camera Resolution
Resolution is a major factor you should think of, in your video conferencing camera. The more your camera’s CCD/CMOS resolution, the better it will be able to capture images. This will in turn increase the image richness and depth of its 3D video capture streaming online.
Note that higher resolution also comes at a higher price. The camera has a lot more data to process to give out better resolution. This also implies more complicated circuitry. This will push up the cost of the product.
- Resolution of the video signal
The video processing chip is what encodes the data. Hence, you should make sure that the camera uses the correct output signal to match its hardware design. An incompatibility here will directly affect the general quality of the image.
Also keep in mind that your camera supports upgrades, so that you do not have to change your product each time you want a recent feature added on. For instance, though you may be looking for a camera that supports 720p at 60 frames per second, you should also look at a future requirement of, say, 1080p.
- Viewing angle
The viewing angle or the horizontal field of view that the video conferencing camera provides is yet another aspect to look at. The larger the viewing angle, the more space it will cover. This means that more people will be visible at the same time, which is especially good in an online meeting or brainstorming environment.
The average horizontal field of view for corporate requirements is about 70° or so.
- Zoom capability
Your camera should have the ability to zoom in and out. This is especially necessary if you need to zoom in on a particular speaker during the course of a conference. Do consider this zoom ratio before selecting your camera.
- Optical zoom
The optical zoom, which is used in the most recent camera systems today, cuts down image noise. 10x optical zoom is the most ideal zoom ratio for video conferencing cameras.
- Digital zoom
If you are looking for a personal webcam, you will most probably not need it to have optical zoom. This will make the set unnecessarily expensive as well. Instead, you can go for one that provides digital zoom. 2x digital zoom is more than sufficient for your needs in this case.
In conclusion, each video conferencing camera brand has different features to offer you. It is entirely up to you to decide on the one that best suits your preferences.
