This feature allows you to obtain a portrait-oriented video stream – effectively turning an HD camera’s 16:9 aspect ratio to a 9:16 aspect ratio. This is where the ability to rotate the image proves to be very handy. These redundant sections either side of the image also consume bandwidth and storage that could really be put to better use. The full area and resolution of the camera’s image sensor is not being fully utilised and this means that evidence of events occurring outside this limited area of coverage may be missed. If you’re monitoring a narrow corridor or passageway, a sizeable portion of the scene is going to be walls either side, making a lot of your image redundant. When choosing a camera for video surveillance in narrow scenes such as long corridors, staircases, aisles and tunnels, the traditional landscape-oriented setup may not be the optimal choice.
