Fish eye view is very advance feature of find'n'secure which lets user search all vehicles by entering the address of the location and defining a radius with in.
for example, an owner of taxi service has a location of the possible client and he want to check how many taxi are in the area and which one is nearest to the passenger then he can use this feature, to find out and assign most suitable taxi. or
a logistic owner want to see how many of its fleet are in a premise of a city.
To check and use this feature, user need to log in into his/her account and then navigate to 'live view' and enter address you have and define radius to check with in and click on search icon , it will list you all vehicles matching your search query. (see below image):
hope this feature will help fleet owner to reach to vehicles more easily. cheers !!
