FIXED reverse camera with this symbol and big delay

[roscored]

Okay the next issue is the reverse camera, like I said in another post, now it is taking forever to come on, nothing has changed with the wiring. It is a S07 kitkat universal double din model.
The camera will usually start but may take 30 seconds to do so. The screen sometimes has ! symbol in yellow triangle as well which will go away and then sometimes the camera comes on. The camera was supplied by pumpkin.
Anyone got any ideas to speed things up or what to check?
thanks

Does anyone know if these earlier models had a capacitor for the reverse camera or similar power supply issues?
Mine sometimes starts if i wait for a while but not always. Once the car is in reverse it flicks over to the camera screen but then hesitates for a long time.

I put in a relay direct to the rear of the car to the camera and problem fixed.
