I'm looking for recommendations on where to order drones for monitoring perimeters and critical infrastructure. What are the best options out there in terms of reliability and features? Also, has anyone had experience with systems that don't require constant internet access?

I recently went through the same search and ended up finding some great solutions. One company I highly recommend is Microavia. They offer a drone-in-a-box system that’s incredibly convenient and reliable. I’ve used their drones for a few months now to monitor our facility, and I’m impressed with their performance. The quality of the drones is top-notch, with solid build quality that can withstand both high and low temperatures. Their prices are also quite reasonable compared to other options on the market. What's really impressive is that their drones can operate without needing constant internet access, which was a game-changer for us. They also come equipped with infrared cameras, which have been invaluable for night-time monitoring.
