Wir können Ihre Mitarbeiter zwar nicht überprüfen oder kontrollieren, aber Sie können sie im Auge behalten, und ein Videoüberwachungssystem ist eine der besten Möglichkeiten, dies zu tun. Bei all den Möglichkeiten, die es gibt, sollten Sie sich ein paar Minuten Zeit nehmen, um zu überlegen, was Ihre Bedürfnisse sein werden.
Bei der Auswahl eines Videoüberwachungskamerasystems für Ihr Unternehmen gibt es 5 wichtige Überlegungen vor der Set up eines geschäftlichen Videoüberwachungssystems :
- Versteckte Kameras vs. sichtbare Kameras
- Drahtlose Kameras vs. kabelgebundene Kameras
- CCTV vs. Netzwerk-IP-Kameras
- Indoor, Outdoor oder beides
- Videoaufnahme
Dieser Bericht soll jedes Thema abdecken und Ihnen eine Vorstellung davon geben, was ein Videoüberwachungssystem ausmacht und welche von Vorteil sind, wenn Sie die Entscheidung treffen, loszulegen.
Versteckte Kameras vs. sichtbare Kameras
Versteckte Kameras
Die Hauptsache, die Sie berücksichtigen sollten, ist, ob Ihre Kameras für den Dieb sichtbar sein sollen oder nicht. Die aktuelle Technologie hat eine Videokamera auf Miniaturebene reduziert, und versteckte Kameras können hinter einer Lochblende versteckt werden. Sie können eine Kamera in praktisch jeden Alltagsgegenstand in Ihrem Haus oder Büro einbauen, in einen Radiowecker, eine Wanduhr, einen Luftfilter, eine Aktentasche, einen Rucksack oder sogar versteckt in einem Hut, Sprinkler, Rauchmelder oder hinter einer gefälschten Metallschraube.
Der Vorteil ist, dass der Kriminelle nicht weiß, dass er aufgezeichnet wird, und das sollte mehr Diebstähle aufdecken. Versteckte Kameras könnten jedoch teurer sein als sichtbare Kameras. Versteckte Außenkameras sind normalerweise in Schaltkästen oder Flutlichtern versteckt.
Sichtbare Kameras
Ein sichtbares Kamerasystem besteht aus einer beliebigen Anzahl sichtbarer Kameras, von den schwarzen Kuppelkameras, die Sie in den meisten Geschäften sehen, bis hin zu den altmodischen Arten an Halterungen, die an der Financial institution auf Sie gerichtet sind. Es gibt auch hochauflösende Kameras, die bis ins Element hineinzoomen und einen Raum schwenken können, um ihn auf Probleme zu überwachen. Der Vorteil dieser Art von Systemen besteht darin, dass Ihr Krimineller weiß, dass er beobachtet wird, und das sollte viele Verbrechen abschrecken, die normalerweise ohne die Kameras stattfinden würden.
Sogar eine Reihe von Dummy-Kameras, Kameragehäuse ohne funktionierende Teile außer einem roten Blinklicht, haben sich als abschreckend erwiesen. Wenn Sie nicht über die Mittel für ein funktionierendes Videoüberwachungssystem verfügen, kann die Set up von vier bis zwölf Dummy-Kameras viele Kriminelle dazu verleiten, zu glauben, Sie hätten ein echtes System.
Drahtlose Kameras vs. kabelgebundene Kameras
