Chain of Custody 
Chain of Custody issues in Terminal Tractor Yard Trailer Shifter Shunt Truck Cameras are similar to those in other applications.
The issues arising from the Chain of Custody are relevant to several Onboard Vehicle Video Camera Recorder applications.
For example, in the Police Patrol Wagon Suspect, Prisoner & Inmate in-Custody Transport Camera application, the officers who operate the Prisoner Vans, Prison buses, or suspect shuttles must be prevented from accessing the memory storage device in the DVR to protect them from the appearance of a conflict of interest.
The best way to do this and prevent the accusation of officer tampering is to remove the officer from all access to the video file memory storage devices. This means the officers have no keys to the locking DVRs.

Those who choose to violate the chain of customer process endanger the officers operating the vehicle, as a false claim from a suspect they were assaulted, beaten or raped in a police vehicle while in custody would be immediately investigated, and a supervisor would immediately pull the memory and should the memory not be there, the officer would immediately become a suspect with motive and accused of destroying evidence.




Choice of Audio
All Vehicle Video Camera Driver / Passenger Safety Camera Surveillance systems sold by American Bus Video Inc. offer Audio recording capabilities. The choice to record audio in these vehicle applications is up to the customer. Terminal Tractor Yard Trailer Shifter Shunt Truck Camera Recorder Systems can record what occurs in the tractor, what might be said by the operator, and what is heard outside the truck, if desired. In cases where Union guidelines may restrict audio recording as the drivers or operators may use their private cell phones and have private conversations they do not wish recorded, then the customer can select to record or not all audio, in or outside the truck. This is occasionally the case with:
Forklift HD Industrial Operator Safety Camera Systems may involve union employees who union may not want their audio recorded.

Police Patrol Wagon Suspect, Prisoner, and inmate in-custody Transport Camera systems are employed in an application where most or all of the LEOs are under union guidelines. This application, in particular, may be much more sensitive to discussions between officers in private and so not record any conversations whiten the vehicle.

Taxi & Limo Video Camera Systems usually restrict all recording of the passenger's compartment audio and video due to privacy concerns.



Some applications rely more on Audio recording than others.
Students With Disabilities & Special Needs Transportation Video camera-equipped vehicles require the audio to be recorded, as this can be a useful tool for reviewing incidents that occurred on the vehicle later.
When cameras are used in Bus Seat Cover Vandalism Camera Surveillance systems, those doing the vandalism to school bus seats are often egged on or encouraged by peer pressure to vandalize. On some rare occasions, those doing the damage are being forced to do so under threat of violence, or gang pressure in which case the audio might help to exonerate them of the damage liability as they had no choice.
Even the Low-Cost HD School Bus Child Safety Camera systems include the ability to record audio because it is an important aspect of the event that can help make the camera system a much more effective tool for fleet risk management.








Choice of Multiple Cameras 
How many cameras do you need for a Terminal Tractor Yard Trailer Shifter Shunt Truck Camera Recording System?
The majority of our customers purchasing these Onboard Vehicle Video Camera Recording solutions select three camera systems so that they can have one camera monitor the KingPin and one camera for each side of the trailer being moved so they can see exactly where they are in relation to those things as they move them in and out of parking areas.

You only require 1 camera to monitor only the 5th Wheel King Pin Locking Jaws. The DVRs all have 4-channel support, so they can accept up to 4 cameras recording simultaneously.

Often, dual applications can be integrated with one system as the DVR can support 4 cameras. For example, Special Needs Wheelchair School Bus Video Surveillance Systems are often added to provide unbiased, expert digital eyewitnesses in these areas where risk management may be high. But usually, they only need a couple of cameras in the short buses, so that offers the ability to address a second problem for the school district at the same time by adding 2 SBC Stop Arm Cameras, so they can document those breaking the laws and passing school buses when they are loading and unloading children.



Driving While Texting (DWT) Epidemic on American highways is out of control and causes immense loss of life in almost all vehicle application markets. So it makes sense if you install a Non-Emergency Medical Transit Camera Surveillance System in your shuttle vehicles to monitor passengers and only need 1 or 2 cameras, the 4-channel DVR can also accept a 3rd & 4th camera if desired to monitor the driver activities, what they see out the windshield, if they drink, smoke, talk on their phones, drive while texting while moving 50+ MPH with passengers.

I have video files of school bus drives with children on the buses who cannot seem put their damn phones down long enough to do their job.

Even the low-cost Mobile Video Vehicle Surveillance Recorder solutions we offer can have up to four cameras per system. The added management oversight offered by well-placed vehicle cameras can provide management staff with answers to many questions when things go wrong and the driver is suspected. Digital Expert Eye Witness Vehicle Cameras in the form of a memory file can show what happened without bias, malice, prejudice, or deceit.
