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.
At my company, I've noticed that something is wrong. I was curious about why people behave in such disparate ways. I bought this disguised smart camera, and I watch them on my phone. I've noticed that they are doing something different in our accounting area. They change the liquidation and inventory. I can't believe they are doing this!!! I trusted them so much. This must be the end! Thanks, ChargeX for saving my company..
