Daredevil uses his super hearing to pinpoint crimes happening in the city while inside his home, and then calls 911 or the police to report them. Might be slower compared to going out and beating those criminals to a pulp, but maybe he can tagteam with Spider-man and give him the locations instead?
This reminds me of that time when Nightwing was recuperating from an injury, and he kept himself busy watching these true crime episodes on tv, then calls the police when he solves the crimes while at home.
