Small, effective and budget-friendly security

A small, effective and budget-friendly sensor kit for our humble home security needs. Power by USB or battery (coin included but provide your own AAs). Then place the egg-sized sensors anywhere you require motion detection. Strong magnetized bases with adhesive are included. We find the four unique tones are especially useful to set as alerts of movement in different areas. If we hear an unexpected noise, we no longer go and check multiple windows or guess; we let the tones guide us! For home, office, college dorm, or even around creepy apartment building stairwells, you can't go wrong with “perimeter security” for under $20. Highly recommend.

VENDOR STANDS BEHIND WARRANTY

GOOD COMPANY, STANDS BEHIND THEIR PRODUCT AND HONORS WARRANTY. THE PRODUCT ON THE OTHER HAND COULD USE MORE WATERPROOFING, SENSOR FAILS AFTER ABOUT 1 YEAR OUTSIDE
