Network IP Camera
XtraSense video surveillance software supports any IP camera with MJPEG video stream or direct image access (has direct URL to capture camera video frame). Video frame rate varies according to network bandwidth and camera's HTTP server response time. The latest version of software has been tested on selected cameras from following manufacturers: AXIS, CONVISION, D-LINK, GADSPOT, JVC, MOBOTIX, SONY, TOSHIBA, TRENDNET and other OEM models.

USB Camera

Multiple USB cameras can be connected to XtraSense at same time. However, not all camera's driver can support it. Sometimes the video will freeze if you try to connect more than one camera. Here we show one of the USB cameras recommended by us:

USB Night vision camera

USB camera connection

To connect multiple USB cameras, the host computer need to have 4, 9, or 16 USB ports. Unfortunately, most computers don't have so many USB ports. A PCI USB card is used to add additional ports to your computer. It is strongly recommended to use a PCI multi-port USB card instead of a external USB hub. External USB hub connects to host computer through one USB port, which may jam the video streams. XtraSense has been tested to be compatible with PCI USB cards. You many have multiple PCI USB cards installed on one computer.

Video Capture Card
XtraSense supports realtime video capture cards only. A realtime video capture card has individual video digitizer for each port and allows application to access all ports at same time. It will present itself as multiple video devices under Sounds, video and game controllers section of Windows Device Manager. A non-realtime capture card use port switching technology to switch between ports at constant speed. Unless the card's driver has built-in port switching features, XtraSense can only work on one input only on non-real time cards. A non-realtime capture card will present itself as one video device regardless the number of video ports.

		XtraSense has been tested working on cards based on video processing chips listed at left. Other chip cards may also work as long as they come with DirectX driver. If DirectX driver was not supplied by the manufacturer, you can always use "Search for driver online" option when Windows prompt for a driver. Alternatively, you can download the latest free universal driver for BT848/BT849/BT878 & BT879 chipsets from author's website or locally (version 5.3.8) .
