昔ハードオフでLogicool C270 を500円ほどで購入して使っていました.ビデオミーティングを良くするようになってC270はマイクもついているので便利に使っていました.でもマイクにノイズが乗るようになりNotePC内蔵ウェブカムやスマートフォンをWebcamとして利用していましたが使いにくいしマイクがついていないので少し不便.今回ひとつ上の機種のC310n を購入しました.
購入したのはAmazon で,-19% off 2400円となっていたのでそれで購入しようと思っていたところAmazon のUSED で2040円送料無料があったのでそちらを購入.
こんな感じのパッケージで届きました.内容物は本体と小さな保証書と取説が1枚づつ.付属物一覧がないので新品もこれと同じかは不明.
このテープの切り方はちょっとアウト感.
外観はこんな感じ.C270とほぼ同じだけどC270より気持ち大きくなって,ケーブル止めのベルクロがありません.
カタログスペックはC270 とほぼ同じで,画角と画素数が少し違うよう.
C270n | C310n | |
---|---|---|
画素数 |
0.9MP |
1.2MP |
対角視野 |
55° |
60° |
Linux端末に繋いでみるとC270と同じくUVC/UAC で認識して特に問題なく利用できていそうです.

現在はAmazonでC270n 2,200円,C310n 2,400円と値段差があまりないのでC310の方が良さそうです.
