Connecting Over the Internet
You may experience some challenges connecting to Surveillix IP cameras over a Wide
Area Network (WAN) connection. This is due to the fact that the IKS-WP806 streams
video over RTSP. RTSP is an excellent protocol for media and is now used on many IP
cameras (including Surveillix) as the default streaming option.
However, RTSP is not suitable for transmission between two locations using two
different routers. In this case, the client (for example, the Surveillix server software)
connects to the camera, 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 ways to solve this problem.
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. When using this
method, 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.
