No. Most local parks do not have security cameras. That is why it is always very important upon entering the park to look for any suspicious activity. If you feel unsafe for any reasons, you should avoid this particular park or this particular area of the park. It’s always best to stay where there are people around. You usually can get a feel pretty soon upon entering a park if it’s safe or not. If you see lots of children playing around with parents close by, if you see many people walking/jogging, lots of activity going on which are normal to see at the park, then that is a good sign. Always keep your eyes open and stay alert especially if you come to the park and there are very few people around. Always keep your phone close by.
