Let me explain what is happening here. In ArmA 2 there are varying difficulty levels. Recruit - Being the lowest, with casual easy mode peripheral vision like dots on everything, which is what you are seeing in that server Regular Veteran - The locations of units no longer show on the map (IMO the optimal difficulty for most DayZ servers) Expert -Being the highest, with 3rd person disabled. Its up to the Admin/Moderator of the server what difficulty level it is set to and there is a large amount of difficulty related settings that can be edited to suit the host. You can see exactly what the default settings are for each difficulty your self by going into (IIRC) Options -> Difficulty Options. TL;DR - Not a cheat but simply a server set to the lowest difficulty level.
