Hi! I bought a camera from my friend, it was cheap because the cables were missing! I don't know which side to solder the +,- and also the 2 data cables. Will it kill my camera if I connect it wrongly? I cant post any images.
It will almost certainly kill the camera if you get the polarity wrong for the power supply.

Sorry, but I can't tell anything from that picture.
Is there any printing on the PCB? If so can you get a close-up of it?
And what is on the other side of the PCB?

I can't help feeling your friend got the better part of the bargain

PS ... a smaller photo (640x480 should be fine) is kinder to those of us with slow or expensive internet connections.
From the markings on the board it appears to be based on the OV7675. The ones I have seen for sale have a 20 pin ribbon connector. You may want to have a hunt around to see of you can find any more information?
Thanks for help, but do you know how do I solder to the joints? Wich side is the -,+?
All I can suggest is finding a datasheet for the Sonix(?) chip on the back (SN9C218P?), identify which pins are +/- and use a multimeter to trace them back to the connector. Don't forget to check what voltage the different chips use.
I have to agree with Robin2 on this one, "I can't help feeling your friend got the better part of the bargain".
It looks remarkably like a TTL version of the OV camera so you will be limited in what it can do.
Best bet is to get the details of WHERE your friend got it and start from there.
Note that I think most of the TTL cameras are now obsolete and that yours appears to have the lens missing too !
It seems to bear a passing resemblance to this one
Or this one
