gmehtaster 0 Posted April 6, 2017 Hi, This may be a super stupid question but please bear with me. I have 5 wifi cameras. The camera has is USB powered. I need to install these outside. I have an electrical box from which I can take a wire but how do I convert the electricity to make sure it is connects to the USB and powers the camera. Is it some kind of adapter that converts electricity to USB. Share this post Link to post Share on other sites
TheF 0 Posted April 20, 2017 USB supplies 5V in general. There are other standards also With the New quick charge thing for Phones, but they are all compatible With the 5V standard. Your Smartphone charger can easily be used to Power Your USB cameras. If you only have 24/12V available, then use a car USB charger. I recently found a step Down module that converts from 9-36VDC to USB Power. http://www.banggood.com/Dual-USB-9V12V24V36V-to-5V-Converter-DC-DC-3A-Step-Down-Power-Module-p-1073671.html?rmmds=search Haven't bought and tried it yet, but it seems powerful for the size.
