Hi, I have a Deco S4 wave system spreading my network around my home and network signals to exterior cctv cameras.  My outside cameras sometimes lose signal so I am hoping to use a TP-Link Powerline AV600 Wi-Fi Extender (that I used before putting up the external cctv cameras). Could anyone with knowledge let me know if adding the Powerline AV600 extender will:

A. Make little or no difference

B. Cause potential conflicts

C. Improve my network range to the external cctv cameras

I currently have a setup with 3 units. A 'main' unit, and two satellites, one at the bottom of my stairs (to my entrance door), and one in my kitchen by the window.

I Have ran an ethernet cable from the 'main' Deco unit to the downstairs Deco satellite which improved my video doorbell signal/operation (the 'main' unit has the ethernet cable connected to my Virgin router). I live in an upstairs flat with an entrance via internal stairway to my entrance door. This is just background information to my question above.

If using a Powerline AV600 extender will not cause any conflicts, I will place it in my kitchen so I can use it to boost the signal to my exterior cctv cameras - if I do this, will it replace or make redundant the Deco S4 satellite?

Or will it only be more helpful if the satellite in my kitchen remains and is boosted by an ethernet cable from the Powerline extender to the Deco satellite?

Any advice will be appreciated.
