Hi can anybody tell me if it is possible to position a Swann dvr in a different room to the router and route the signal wirelessly using something like a wifi adaptor.
This shoudn't be an issue provided you're able to create a reliable wireless connection between the NVR and router. Things like corner walls and an abundance of wireless devices can cause havoc with the wifi signal, so do keep that in mind.
Whilst I've not personally tried it with a Swann NVR, it's not an uncommon setup and works well with other manufacturers so it's not a stretch to assume it would with Swann too.
