No, the ChargeX does not need an SD card in order to use or watch live feed. However, if you need to record and save the videos you will need to purchase one. SD Cards are available at All Trends USA.
if you have trust issues with your partner, you better buy this stuff. It's really helpful I swear to you all because using this camera I caught my boyfriend with his ugly chic in her apartment. They didn't know that I placed this ChargeX camera in his room. I catch them in action LOL! it's funny but very satisfying in confronting and slapping them both!!
