NoraSector is built for speed.
NoraSector was built from the ground-up to stream data to clients as fast as possible. Typical delays are less than one second from reception to playback. NoraSector uses the same technology as VoIP calls to create a low-latency stream and custom software to tune between channels.
Typical scanner streaming services use some amount of buffering (or waiting until an audio segment is entirely recorded and uploading it) and eventually introduce a significant delay, meaning the information you're getting is noticeably lagged from when the transmission went over the air. NoraSector's architecture transmits data as it comes in through a low-latency, bufferless system that gets audio to listeners typically in under a second, even on a cell connection.
Wired internet connection
Here we see approximately 200ms of delay compared to the physical scanner. This is an ideal connection (wired Ethernet connection over fiber).
Cell connection on VPN
In this video we can see approximately 500ms of delay between an actual scanner playing back received audio and NoraSector, under less than optimal conditions (a cell connection on a VPN). This was taken with a much earlier iteration of the NoraSector UI.
Tune channels instantly. Listen to many at once.
NoraSector's streaming technology allows you to listen to multiple channels at once, and will automatically tune to active channels, similar to how a trunking radio scanner works. Your channel selection is saved to your browser's local storage so it remembers what your preferences are.
Hear what you missed
NoraSector records all transmissions and uploads them to the cloud. Play back what you missed or download an audio clip of it. Recent recordings are updated in the UI the instant they get uploaded, so you don't have to look far to play back audio.
NoraSector sources incident information from local agencies and pushes them to clients as soon as they are updated. Incidents are marked on a map and pushed to clients instantly.
NoraSector's map shows jurisdictional boundaries and highlights when speakers within those boundaries are speaking. This gives both a better understanding of where activity is occurring as well as linking to those agencies for additional information.
A traditional trunking radio scanner costs anywhere from $300-700. These devices allow you to instantly listen to the airwaves around you, wherever you are. They work with no Internet connection and can tune to a variety of systems. They're extremely valuable tools, but their price tag limits their accessibility.
NoraSector is different. It uses software-defined radio to tune entire radio systems and stream those with extremely low latency to the web, and allows you to visualize what channels are active and where that activity is. NoraSector was designed to be the tool you pull out of your pocket when you hear a siren going by to understand what's going around you.
