I downloaded some mods and make a new survival world to play with them, and in the middle of playing i thought about Security craft, since it adds cameras to the game so i could see what's happening outside my house, if there are any mobs there or anything like that, but when i got all the materials for a camera 6 Iron, 1 Stick, 1 Redstone Block and 1 Reinforced Glass Block, and put the all in the crafting table, i can't craft anything with them. Could anyone help me with this issue?

You need a Reinforced Block of Redstone.
