What i'm planning on doing. is setting up a dvr in one of my sheds in the garden. Basically i have a old Swann 4 channel DVR. its not a HD one. i only want to view the cameras via the Swann netviewer app on my laptop at home. how i plan on doing this is this way. I have my indoor router. and another router set up in one of my sheds connected via a 50m ethernet cable. it works fine giving me good speed and wifi. i have a old dahua 16 channel dvr connected to the router in the shed. plus a few ip cameras now because i needed more ports than what the router as i connected a netgear port switch. this is the part i'm not sure of. if i put my Swann dvr in my other shed and connect it to the port switch using a 20m ethernet cable and power up the DVR. i should be able to view the cameras using the Swann app. am i correct or have i missed something out i;d rather ask before pulling cable then finding out it wont work,,
