CTRONICS Cables

[Davejel 0]

Hi, I would be grateful for any assistance

 

I have recently purchased a Ctronics cctv camera from Amazon

Ctronics 4MP 2K Security Camera Outdoor, WiFi CCTV Camera Outdoor Wireless Home Camera Pan 355° Tilt 90° & 25M Night Vision, Human Detection with Auto Tracking, 32G Micro SD Card Included: Amazon.co.uk: Electronics & Photo

and now wish to purchase an extension power cable. 

The cables I have found on Amazon have camera plugs with dimensions of 

2.1 X 5mm.

Can anyone confirm that this is compatible with above camera

I also have another question regarding the arial. This camera will be sighted where my wi-fi reception is very poor. Is it possible to purchase an extension cable for the arial and if so can anyone recommend one.   Many Thanks,   Dave
