Hello I bought a wifi jammer from you

Hello I bought a wifi jammer from you and it was working great it was blocking my neighbours Wi-Fi cctv camera but now it doesn’t effect the cameras as before I could see a red light on the camera flashing as it was trying to reboot but now I don’t see a light flashing on the camera so I know they were taking pictures of their camera so I think they have been in touch with the camera manufacturer and they have sent some connection to stop me from jamming their camera or they have have Ethernet cable

I am not sure what they have done but the camera is the same and the recording cable from the camera to the recording box is the original have you any item that will still block their cctv Wi-Fi camera

No there only Amazon Wi-Fi cameras but I can not jam them the outside of them is no different and they have not but an Ethernet cable from the camera to the recording box I don’t if they have put a wifi signal blocker inside the property to stop me jamming the cameras or they have a stronger password I ,could jam them before but now I carn’t is there nothing I can do about these cameras

thank you
