Since the CrowBox needs to be plugged into a power main in order to operate, it's important to observe some safety precautions, especially if your CrowBox will be deployed in an area that can be exposed to water from rain, sprinkler systems or any other water source.

If using an extension cord, be sure to use one that's labeled “outdoor type” or “for outdoor use”. Also, be sure that the extension cord you plan to use is in good condition.
The most important electrical safety element is the use of Ground Fault Circuit Interrupt protection, usually called GFI or GFCI. There are three good GFCI options:
The outdoor power outlets in your location may already feature built-in GFCI protection. This is easy to determine- if the outlet features small recessed buttons marked “TEST” and “RESET”, then the outlet provides built-in GFCI protection. Often, these outlets will have hinged plastic covers.
Outdoor extension cords with built-in GFCI protection are widely available. These cords usually feature a small box somewhere along the cord's length with the same “TEST” and “RESET” buttons as other GFCI-protected products.
NOTE: Not all outdoor extension cords are GFCI-protected. Check the label and look for the buttons.
If you already have an outdoor extension cable that you want to use, but it is not GFCI-protected, you can buy a very short extension cable with GFCI protection. To use one of these, you plug the GFCI cable into your power outlet then plug the outdoor extension cable into this in-line GFCI cable.
