Where is the location of the camera for Metal Gear Solid 1 for the PlayStation one

rember the place where you fought ocelot for the first time,well try to get back to that place but instead going through the wall there is another wall which is right beside it try using the c4 to blow it and then you will find gun cameras and two doors one of the two doors has the camera inside but make sure to have card level 6 before you go to that place
