            Системы видеонаблюдения – это комплекс оборудования и программ (камеры видеонаблюдения, мониторы, объективы, видеорегистраторы и пр. видеооборудование), которое используют для организации охранного видеонаблюдения на объектах, незавимисо от их территориального месторасположения.

            Источники питания


            Можно выделить два типа источников питания: линейные и импульсные.


            Линейные источники:
            Строятся на основе низкочастотного трансформатора и при необходимости выпрямителя, фильтра и стабилизатора. Имеют значительную массу и габариты. Кроме того стабилизатор рассеивает значительную мощность, что ухудшает КПД и тепловой режим. Правда существуют варианты с импульсным стабилизатором, где проблема нагрева минимальна, но такой вариант опасен. В случае пробоя переключателя на оборудование попадет полное напряжение с выпрямителя, которое может составлять 20 – 30В. Оборудование при этом гарантированно выйдет из строя.


            Импульсные источники.
            В импульсных источниках сетевое напряжение выпрямляется, фильтруется, и подается на высокочастотный преобразователь, который имеет малые габариты, массу и тепловыделение. К тому же импульсные источники допускают большие отклонения напряжения питающей сети.

            При прокладке кабелей питания надо учитывать:
            1. Напряжение проходящее по проводам
            2. Мощность нагрузки
            3. Условия окружающей среды.
