The MAX3232 takes 0-5V signal and outputs +- 13.2V. You can only use 0-5V signal on Arduino so remove the chip.

The second picture is pretty clear:

There is an empty foot print for a chip and two jumper wires were soldered on. If you don't order RS232 version by mistake you don't need this step.

Do you have this exact camera?

You need to know this too:

I have a few water-proof version of this camera. If you use hardware serial, it's working fine. If you use software serial, too many frames are garbled (10%).
