This bundle of four white Axis Communications T91A33 Lighting Track Mounts enables flexibility in video surveillance installation of cameras. You'll be able to reuse existing lighting tracks in your environment for mounting a wide range of Axis network cameras. Drilling or alteration to your existing lighting track systems are not necessary for installation. Simply attach the mounting accessory to the lighting track without any tools. Additionally, you'll be able to run the network cable alongside or behind the lighting track. Mounting holes on the T91A33 suit a wide range of Axis cameras and camera stands. After mounting the camera directly to the surface of the accessory, you'll be able to quickly reposition the camera along the track to cover a new field of view.
