This older bus was soon to be replaced, so the customer asked us to keep all cables surface mount so they could easily move it from this bus to the new bus in 6 months. Professional school bus video or vehicle camera mounted with no cables for children to tamper with. STC & BTC professional cameras are true vandal resistant cameras that will not crush like eggshells when struck with a child's fist or shoe. Disposable plastic or eggshell thin sheet metal cameras are a poor substitute for true vandal resistant camera. Notice the IR LEDs are built in as is the mic, so there is no crap hanging off the camera to provide a weakness to fail or a potential hazard to the child, just a all metal rounded case.
