You’re looking at devices on the network the app identified, you’ll want to keep an eye out for anything that shows a camera manufacturer (like Nest, Arlo, or Wyze), or lists as “IP Camera.”

Why would a helicopter fly at night without lights?

Thus no worry about a crash and no need for lights.

Why do police helicopters fly in circles?

Flying around in circles enables them to stay on station for longer. Helicopters need less power to fly forwards than they do to hover. Minimum power speed is about 65–70 knots for most helicopters. Flying around in circles enables them to stay on station for longer.

Why are helicopters so loud?

TLDR – Helicopters are so loud due to blade-vortex interaction. The air pressure decreases above and increases below the blades as the main rotor spins, providing upward thrust. A vortex is created to even out the air pressure, which produces sound vibrations when it hits the next blade.

Is it loud inside a helicopter?

In the majority of today’s commercial aircraft the level of cabin noise is generally lower than 80 dBA. However, in most helicopters the levels could be considerably higher, reaching the values beyond 100 dBA in some older production models and higher power settings.

Can helicopters break the sound barrier?

“Helicopters have ‘retreating blade stall,’ and getting through it is the equivalent of breaking the sound barrier for heli- copters,” explains Steven D. Weiner, director of Engineering Sciences for Sikorsky Aircraft Corporation.
