@BogEyes I know all of my Hikvision cameras (6 bought circa 2014) are still going strong, as is the NVR. Albeit they were originally Chinese hacked and bought via Aliexpress. It does seem to be a different market now that option has been somewhat eliminated. I can still see the Hikvision for sale on Amazon but elsewhere it is difficult to get pricing. I have been happy enough over the 6 years of constant and reliable use from them.
@WJA96 seems to have experience with the Dahua brand and is far more understanding with what is relevant and on the market today.
Each of the six cameras on our property has similar sized connectors you are referring to but they each terminate in a plastic type junction box next to each camera where the external grade Ethernet cable is ran to.
As WJA96 has responded you can see the post he refers to a page or two back.
I'll have to watch to see what you are selling in the MM soon @WJA96.
Access to Hikvision cameras here in the UK hasn’t changed since you bought cameras 6 years ago and gaining access to pricing only requires you to register with the website to see such pricing. I get deliveries every week. Some online stores are even stocking Dahua cameras along with Hikvision which I also buy weekly.
Today, the average Joe bloggs has easier access to Hikvision and Dahua equipment than you did a number of years ago. If the camera you want isn’t listed on their site, a simple email and they can get it whether it’s Hik or Dahua.
