Sunny Singh 0 Posted April 10, 2022 Hi All, Please can someone help. My DVR is all of a sudden asking for a password. It used to be *blank* and since attempting to enter common passwords, the box gets blocked for several minutes. There is no reset hole on the DVR and can see cameras via the screen attached however, no longer through our phones unless our phones are connected to WiFi. Before we could access cameras via 4G.
