Currently the cameras cannot communicate to the external LAN because they are on a different LAN segment. The actual reason I wanted to test your proposal, is because I want to be able to have the camera connected to the NVR internal PoE switch (thus saving an extra external PoE switch), preserve the cameras different IP LAN segment as defined by the NVR and finally enable the cameras to communicate to the outside world through the NVR LAN port (thus enable all the communications like the different motion detections from the camera to the LAN and sending of snapshots). Have you successfully accessed yoor cameras with your proposed solution? Unfortunately the camera IP () is not accessible from my LAN. I defined a static route in my router as you propose. I telnet to my NVR and the ip_forward value is 1. However I wanted to test your proposal for other reasons. Therefore I can access my cameras officially with the Virtual host feature (essentially a port forwarding internally to the NVR). From this firmware version onwards, HIK has enabled the telnet and also the the virtual host setting which I have enabled and it is working properly. I have the 7604NI/SEP with firmware 3.0.9 build140928. Re: Hikvision POE LAN segment - access to cameras without virtual host or extra wirin With root access using the Linux shell, we can see that by default, IP forwarding is switched off. However - it's possible to enable that facility within the Linux environment. The Hikvision NVR with POE ports has 2 network interfaces, one for the normal LAN, and one to service the POE switch ports on a different network segment, but by default no active facility to route or forward IP packets between them. Note also that I haven't assessed in detail what effect if any on performance would result, though none was obvious.Įssentially - a Linux installation by default does not have IP routing (aka IP forwarding, not to be confused with port forwarding) enabled by default. It's easy to configure and has plenty of tools to see what's going on - and I don't have a spare camera on the shelf just now.

Note also that I have only so far tried it, for the ease of testing, using a PC as the POE port network device instead of a camera. *Warning* Don't experiment with this unless you're reasonably network and Linux savvy, and accept that there is some risk when delving around in the internals of an embedded Linux box.īut for the occasional need to access POE-connected cameras directly, this method may be worth exploring. Here's an interesting thing I just tried - inspired by a thread or 2 here where people need to access their POE camera directly (for fine configuration, not streaming) but by default can't easily as they are on an isolated POE network segment on the Hikvision NVR.
