+====== Camera ======
+The **Camera** lets you gather information (specifically, distance from nearest block) in your surroundings.
+===== Recipe =====
+**NOTE:** The stone bricks on top can be any type of stone bricks.
+{{ :wiki:computronics:camera_recipe.png |}}
+===== API =====
+==== Redstone ====
+Since 0.1.4, you can hook up a redstone wire to the camera to get distance data - the energy level reflects the distance (15 - 0-1 blocks away, 14 - 2-3 blocks away, ...., 1 - 30-31 blocks away).
+==== OpenComputers/ComputerCraft ====
+^ Command ^ Added in ^ Description ^ Usage ^
+| distance([x, y]) | 0.1.0 | Calculates the distance of the closest block. | The x and y parameters are optional. |
+=== Robot Camera Upgrade-specific ====
+^ Command ^ Added in ^ Description ^
+| distanceUp([x, y]) | 0.6.4 (broken before then) | Acts as a camera pointed up. |
+| distanceDown([x, y]) | 0.6.4 (broken before then) | Acts as a camera pointed down. |
+==== NedoComputers ====
+^ Address ^ Read ^ Write ^
+| 0x00 | X direction (-32768 - 32767 == -1.0 - 1.0) | X direction |
+| 0x02 | Y direction | Y direction |
+| 0x04 | Distance, measured in 1/64ths of a block. | - |
+==== Examples ====
+=== ComputerCraft ray caster ===
+<code>local camera = peripheral.wrap("right")
+local array = " .,-=+xX#"
+local monitor = peripheral.wrap("monitor_0")
+local yp = 1
+monitor.clear()
+monitor.setTextScale(0.5)
+monitor.setCursorPos(1,1)
+for j = -0.35,0.25,0.025 do
+  for i = -1,1,0.036 do
+    local d = camera.distance(i, 0-j)
+    local a = 1
+    if d > 0 then a = 2 + (8 - math.min(8, (d/1.2))) end
+    monitor.write(string.sub(array, a, a))
+  end
+  yp=yp+1
+  monitor.setCursorPos(1,yp)
+end</code>
