Ok sorted it 24 hours later. So I had to go to the hikvision web site here
DS-KD8003-IME1(B)
then download the latest firmware_V2.2.75_231213
Then extract it to my pc. The use SADP tool double click the ip address of my intercom. The login using the opened web browser I used edge on win 11. After logging in select configuration at the top and maintenance on the left.
Next to upgrade I selected “controller “ then pointed the import file to where I had extracted my firmware file on my pc. Then I waited 5 mins while it patched the bios and rebooted. Once it did that when I added it in iVMS it showed online. Hurraaa…
