How do you deploy the system and does the system need to travel with the external hardware attached?
Mobile Pro Systems offers easy mount/release tool-less brackets for cameras and other external equipment so that you can store them inside the trailer while traveling. The key is to be able to deploy with one person, who has limited technological experience, in as short of time as possible.
Others have inadequate mounting systems for their cameras and communications equipment. Some force the need to travel with your vibration sensitive electronic hardware permanently mounted to the mast, or you need a toolbox and higher level technical know-how and possibly a ladder to mount and attach the electronics for deployment.
