When buying a webcam, consider its uses, image quality, resolution, processor and graphics card, internet connection, portability, microphone, and additional features like zoom and mounting. Webcams can be used for video calls, recording, streaming, and security. Prices vary, but moderate resolution is usually sufficient for clear motion video. High resolution is better for photos and high-quality video. A fast internet connection is necessary for video chat.
Usually the first thing to consider when buying a webcam is how much money you are willing to spend. Fortunately, due to constant advances in technology, you don’t have to spend a lot of money to get a versatile webcam with lots of useful features. A webcam can have many uses and you should first think of all the things you could use it for once you get it home. These useful devices can be used as video phones, for recording video, for taking photos, for streaming live video over the Internet and even as security devices to monitor your home or office while you’re away.
Since buying a webcam is a priority, the image quality of the camera ranks right up there with the cost that many people are willing to pay, and the price usually increases as image quality increases. The image quality of a webcam is determined by its resolution, which is expressed by the total number of pixels. Webcams with a moderate maximum resolution, such as 960 by 720 pixels, are generally all that is needed for the camera to be able to capture relatively clear motion video. You may want to consider a camera with a high resolution, such as 1600 by 1200 pixels, if you plan to take pictures with the camera or if you want to post high-quality video on the web. Also keep in mind that your computer will need to have a fast processor and a good graphics card to see the webcam’s full potential, including a high amount of frames per second for better quality video.
You will also need to have a high-speed internet connection if you plan to send and receive video via a webcam. There are many websites where you can communicate with others via video chat and some even offer free services to connect with other people online. Other services and programs allow you to set up a home security network that uses the potential of a webcam and can even turn on the camera when it detects movement in the monitored area.
Most webcams are small enough to be portable, but size may be a factor for you if you have a laptop and plan to use a camera outside your home. Another feature to consider is a built-in microphone, and some webcams have more advanced microphones than others, with noise filters, sound detection, and more. Other features to keep in mind include digital zoom, automatic face detection, effective pixel resolution, and the type of mounting device that comes with the webcam.
