If the time comes when you need to gather information on someone (ie spy on someone) here is the gear you will need. Note that said spying may not be legal/moral/ethical...
- Cell phone with GPS
- Binoculars (for surveillance from a distance)
- Digital camera (for pictures of the person/people/evidence/documents/etc)
- Digital camcorder (if a picture is worth a thousand words, a video is worth 10,000)
- Night vision goggles (for better vision at night...)
- Wireless spy camera(s) (for watching/videotaping the action)
- Wireless audio device (for listening in)
- GPS device (for noting locations)
- Parabolic microphone (for listening over a distance)
- Voice activated audio recorder (for bugging certain types of locations)
- See behind spy glasses (gimmicky but they actually work)
- Telephone voice changer (for making calls, leaving messages with a different voice)
- Lock pick (for covert entry)
- Phone tap (for recording phone coversations)
- Lip reading (a skill that comes in handy sometimes)
- Computer keystroke logger software (for password grabbing, etc)
- Remote screenshot software (to see what your mark is seeing)
- Cell phone spy software (to capture cell phone coversations)
- Assorted covert audio/video recorders (disguised as a watch, a button an a shirt, a pack of gum, etc)
