Awesome wireless Night Owl security system. Has its own DVR and can setup custom recording modes, including motion detection (you can even adjust which frames in the field of view you want to set on motion detect). Have successfully used this system to prosecute a home invasion in the past year. Allows you to replay and zoom in. Also has audio functions to talk to whoever is on the other end of the camera using the app. All in all a great system. Includes 3 outdoor cameras and 1 indoor camera.
