Waveshare IR-Cut Camera 5 MP OV5647 Sensor Embedded IR-CUT Supports Night Vision Adjustable Focus for All Version of Raspberry Pi with 50 Degree Angle of View

The camera itself is really great, the IR cut function means it gives a great picture both at night and in the day. I got excellent results when I tried it with my Pi 3. However I actually bought it to use with a Pi Zero, but I just can't get it to work. It's listed as being compatible with all versions of the Pi, and the description even mentions that to use the camera with a Pi Zero you will need a special cable, which I bought. However when I tried it with a Pi Zero it just wouldn't work.I've been in touch with Waveshare support and they suggested using a 3amp power supply, trying a different Pi Zero and a different camera cable, all of which I did but it still wouldn't work.The only way I got the camera to take a picture was to remove the IR LEDs, which suggests that the Pi Zero just doesn't provide enough power to make them work.

Camera isn't 5mp, it clearly says 3mp on the lens casing.
