SPD-152 compatibility issues with PELCO Sarix 3 pelco imp231-1irs

Hi,

I'm having issues adding PELCO imp231-1irs cameras, 

I can get them to add and say "Connected" however there's no Video feed and after a few seconds a triangle with a ! appears on the camera in the left column  

There's nothing in the Logs

Cameras are listed as ONVIF TYPE S 

thank you
