It depends on your needs. There are several different types of surveillance cameras, but they can all be divided into three main categories: outdoor cameras, indoor cameras, and door cameras. Outdoor cameras can withstand weather and wind, while indoor cameras are intended to be used for monitoring indoor environments. Door cameras are getting more and more common; they usually replace your doorbell and let you see who is outside the door.
A superior surveillance camera offers high resolution, two-way communication, and backup solutions for communication and cloud storage.
