دوربینهای مدار بسته معمولاً برای نظارت بر اماکن داخلی و خارجی مورد استفاده قرار میگیرند و بسته به شرایط محیط انواع مختلفی دارند. اولین دوربین مدار بسته در سال ۱۹۴۲ توسط ارتش آلمان برای نظارت بر چگونگی شلیک موشک V2 در ایستگاه پرتاب این موشک نصب شد. حدود ۷ سال بعد در آمریکا سیستمهای مدار بسته تجاری به بازار آمد با نام Vericon و جالب توجه است که استفاده از این دوربینها نیازی به مجوز دولتی نداشته است.
اولین دوربینهای تحت شبکه در سال ۱۹۹۶ توسط شرکت “Axis” با استفاده از پایه نرمافزاری لینوکس (Linux) تولید شد، این دوربینها براساس استانداردهای HTTP و RTSP طراحی گردیده بود و از استانداردهای IP و شبکه برای ارسال تصاویر در قالب اطلاعات (Data) استفاده میکرداستفاده از دوربینهای تحت شبکه به علت بالا رفتن قابلیتهای آنها نسبت به گذشته روز به روز درحال افزایش است.
نام گذاری دوربینهای مداربسته قاعده مشخصی را پیروی نمیکند و بیشتر بر اساس شکل ظاهری دوربینها، نوع کاربری و بعضاً نام اختصاصی یک کارخانه است (مانند دوربین مکعبی یا ریگولار که نام گذاری کارخانه کمدکس است). از اینرو در بحث دوربینهای مداربسته نامهایی چون: دام، باکس، جعبهای، صنعتی، بالت، استوانهای، فشنگی، تفنگی، مینیاتوری، پین هول و….
