Connecting Over the Internet

There are some challenges with connecting to Toshiba IP cameras over WAN (internet)
connections because the camera streams video over RTSP. RTSP is an excellent protocol for
media and is now used on many IP cameras (including Toshiba) as the default streaming option.
RTSP, however, is not suitable for transmission between two locations that are behind different
routers. In this case, the client (for example, the Toshiba HVR or NVR server software) connects
to the camera, and then requests a stream. The camera uses that connection to return a stream,
but since the connection originated on the client side and has now switched to the camera
(remote) side, the router does not have any way to determine where the traffic should be routed,
so no video appears at the recorder. There are three solutions to this.
1. Connect modems on both sides directly to the recorder and camera. If there is no router,
no network address translation is needed.
2. Use routers with VPN support and set up a small VPN. Once this is done, the traffic will
be treated as though it were all on the local network.
3. (Best solution) – Use routers with connection tracking. This is quite easy; VOIP also
uses RTSP and faces the same challenges. If a router is marketed as having "VOIP
Support", it will have the necessary connection tracking capability to allow any type of
RTSP communication (not just VOIP).
With proper planning and the correct equipment, RTSP cameras CAN stream over the WAN to a
recording device for minimal additional cost and labor.
Please contact Toshiba support if you require any additional information on these topics.
