No, the HiddeX 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.
Due to its exceptionally small size and inconspicuous design, this HiddeX Camera is ideal for spying in your private space . Nobody will recognize it as a camera because of its look. It also incorporates a night vision mode, has HD camera, motion detection and can watch both live and recorded. I've been using this device since my friend recommend this. I also used this to monitor my partner if she is cheating on me. Better she won't!!! Recommended device ever!
