been years since i set up a new system or cameras, now i cant work out how to do it.
i setup the NVR, it asked for password so i set up the password e.g. abcdefg and this is associated with username of admin
i plugged in the camera, it detected it, wrong username and password displayed on screen. so i went into camera setting on NVR and modified the password to abdefg with username of admin the same as in NVR so they are both the same.
still displays on screen wrong username and password for camera.
how do i get it to connect??
