Arrived in good time. The camera and cable are separate from the device so you can buy a device and buy different cameras with different sized lenses and cable lengths for different jobs. I have bought the 3.9mm lens to see if I can use it as a borescope for firearms to check the insides of barrels for faults and cracks. Being able to buy multiple different camera types with different cable lengths is very useful and is a clever idea as it is more compact to carry the device and camera/cables separately. Have not used them yet.
