What kind of tools would you be able to use if you are working in surveillance?

RFID, CCTV, pan-tilt zoom, mantraps, smart cards, etc. Try researching physical security and information security. Are you sure you need to get a degree? The CompTIA Security+ certification covers all aspect of security from physical security to logical security. The cert is difficult to get and makes you competitive for jobs. You can obtain the cert within ~4 months of studying, you can study on your own for no cost by doing research on the internet. Have you looked at the openings for the jobs you want? Are there other certs that you could get? Overall, my point is that the certs require you to know the tools as well as know a bit about how to use them and there are no constraints to this study (e.g., you can do it while still in high school, you can study at your own pace).
