## Questions & Answers

**Q: Why have you got a misleading image?   the image is for  a 1tb card whilst the text is for 128g?**
A: Agreed, this is misleading as the image should represent the item selected for sale. Other sellers have correct images assigned which updates when a different capacity is selected. I was mislead into thinking the 1TB card was a lot cheaper... click bait!

A: Despite this model would work with CCTV camera, it will have warranty voided. I recommend to purchase the High Endurance instead. It is designed for such a devices and will be covered with full warranty.
