Clearly under the impression that you can never have too many webcams, Logitech has announced four of them onto the unsuspecting public.

All four are HD devices featuring Logitech's Vid HD for HD video calling and Fluid Crystal tech for "crystal clear images with smooth, fluid motion and rich, true-to-life colors" - you get the gist of it.

The C270 and C310 are the two standard models getting the basic features throughout the range; which includes a handy one-click upload to Facebook and YouTube; Majix photo and video editing software, for polishing rough edges out of videos; and a video and picture gallery, for easy access to content. The C270 takes 3-megapixel photos whilst the C310 get a 5-megapixel snapper.

Moving on up through the range we get the portable Logitech C510, with a "fold-and-go design". Plus, the 360-degree full-rotation allows you to swivel the webcam around and include more people on your video calls and recordings. You'll also get an 8-megapixel camera.

The final edition is the Logitech HD Pro C910, and is the all singing and dancing, top-of-the-line model. You'll get Full HD 1080p video recording, whilst video calls can be made in 720p, and two mics should give some good sound quality. At 25mm deep it seems pretty slim and a 10-megapixel camera will help you take some quality pics.

All major video-calling clients are taken care of including Skype, Windows Live Messenger, Yahoo! and Gmail.

Prices start from £24.99 and £34.99 for the C270 and C310, whilst the C510 will cost £44.99 and the C910 £89.99. And all the webcams should be available in the UK come July.
