DRONES OF ISIS....., page-9

Other companies have drone guns too though (WIFI/GPS jammers, net guns, pellet shotguns, etc). DRO doesn't sell anything that other anti-drone outfits aren't also offering.

D13 has a unique system, which can be a setup and forget system, whereas drone jamming guns require someone constantly on patrol, and you need 1 person per drone. They have also got some patents behind their technology, and can customize it to suit customer needs (after-sales support opportunities)

DroneGun:
- Require 1+ person on patrol, with very quick response (couple of seconds if drone is flying quickly)
- Require LOS, limiting to day-time use, unless those on patrol have night-vision.
- Weighs a fair bit to be walking around with, but time to suit-up defeats many usage scenarios.
- Drone software must be on factory defaults to land if it loses WIFI/GPS signal
- 1 anti-drone gun/person per drone
- Offers only one solution, force drone to descend vertically and land

MESMER:
- Setup and forget
- After sales-support opportunities
- Handles multiple drones simultaneously
- Multiple response options - push drone back, land at specific spots, send message to drone's controller, etc.
- Don't need to have people on patrol, or constantly alert
- Works at night and without LOS]
- Can be hidden and less visible then someone carrying a backpack and jamming rifle.
