Hikvision Nvr

[spy 0]

Hi All

I have a Hikvision Nvr with 6 Cameras attached.

I am wondering if i could add a couple of battery wireless cameras to the NVR something like a Blink or Tapo

or any suggestions would be welcome so i can view them on my cctv monitor.

I cannot get any cable to the place where i want to install the camera.
