I have a digital wireless DVR with cameras, they do not connect to the WiFi . My DVR will not power on the place where the 5 volt wall charger connects is loose and will not connect. So I can not view my cameras. Without buying a new DVR is there any App or software I can download on my android tablet or my laptop with windows 10 that will Pair to the cameras so I can view the live footage? Any help would be greatly appreciated. The DVR I have is a 4 Chanel 2.4 GHz model is a MountainOne 7" wireless DVR model VS-602D. Thanks
