The advantages of security video on a smart phone
September 14, 2010 By Steve Bocking
However, offering remote capabilities for these latest gadgets is very much contingent on the power of security system software being used, be it a VMS or an access control system. For example, some VMS software can only manage one video stream per camera or cannot “throttle” the bandwidth per camera to efficiently stream over the internet or a WAN. For an integrator with a project with a “real” control room and a requirement to stream to a handheld device, it is important that the integrator selects a VMS that can control two or more video streams per camera. This will allow for high-resolution local viewing and recording on site and low resolution and bandwidth transmission over cellular to a smart phone. To support this type of setup, it is also very important to make sure that the selected IP camera offers multiple video streams. Two streams is becoming a very common feature and some cameras today even offer up to five streams. Ideally, the selected smart phone will support cellular transmission and also broadband wi-fi (internet). This way, costs can be minimized by using wi-fi for video streaming, when it is available, since transmitting video over cellular can get costly, if used often.
The key word is flexibility and making sure to ask the right questions when choosing your security system. Just because a VMS can record and view IP cameras, does not mean it is taking full advantage of the features that IP cameras offer and how they relate to managing CCTV systems over large area networks, the Internet and even cellular networks for mobile devices.
