Sightings are other people’s alerts. The Perch sensor triggers alerts based on community intelligence. You can find your own alerts and details in Perchybana.
Sightings give you an indication of who else is seeing what you’re seeing, and how they are dealing with the indicators that you’re both alerting on.
Detailed sighting information can be seen if you dive into the details of an alert (ie. view the indicator details). From the alerts page, click on the launch Details button to view the indicator detail page. From here, click on the Sightings tab to view more comprehensive sighting details based on the information your communities provide you.
