SD4HD Driver Safety Series
The SD4HD Driver Safety series offers a low cost active driver training device that can help reduce dangerous driving behaviors  reduce fleet driver risk from those dangerous driving behaviors and actively remind the drivers to abide management safe driving parameters like maximum speeds, reduction of hard turns and rapid acceleration or breaking. The system incorporates a higher level of Video Evidence Security virtually eliminating the possibility video files will be viewed by outside parties  on unauthorized video players. This enhanced video file security is shared technology and incorporates the same enhanced Video Evidence Security of the High Definition FHD4, in a D1 resolution lower cost school bus pupil transportation solution.

The SD4HD mobile vehicle surveillance DVR has no moving parts in the recording mechanism, making it 100% Solid State Digital. It is able to endure very harsh environments making them well suited for high-risk vehicle applications that require rugged solid state dependability for video evidence. Driver Behavior recording aspects of the 3-Axis accelerometer, combined with the active driver alerts provide a powerful tool for management.

Wide chart deflections can indicate dangerous driving behaviors that may indicate a need for additional fleet driver risk management oversight by supervisors or in some cases management intervention in order to prevent those recorded and identified dangerous driving behaviors from creating a potential threat to life and limb, risk of capital investment in assets or liability lawsuits. Distracted fleet drivers often display hard braking as they are often not paying attention to the vehicle in front of them until they are about to hit it, hence the cause for the hard braking. Fleet driver risk management is enhanced when clear indications of dangerous driving behaviors can be identified prior to the accident scene reconstruction when it is already too late.

Fleet Driver Risk Management as well as Driver Safety Training of  specialty vehicles like buses, trucks, concrete transports, fuel trucks addressees the fact many not them are top heavy, lateral inertia of even .6G can be dangerous, and incidents of this may be cause for concern and immediate attention to prevent loss of control, or possible rollover beyond the .6G threshold. Safe Driver Training Systems like the SD4mX can alert the drivers of their potentially dangerous vehicle operations w/o any need for supervisor or management review of discussion. Active alerts when they exceed safety thresholds of vehicle operation can immediately let a distracted driver know they are not in control of their vehicle before any review is performed on any documented events.

Choice of Cameras with above systems:


PD-A Camera

Named as such due to widespread application in police cars for recording of interior car activities. High Definition 720P-AHD, with a very wide angle 2.5 mm lens that provides an exceptional wide Field of view. The built in audio is very clear and the light sensor automatically switches the camera from color in normal ambient light to Night Vision via IR LEDS in low light environments. The heavy duty metal shell provides a much longer service life than the cheap plastic camera cases polluting the market.


BTC-A or Black Turret Camera

This camera is generically a dome camera with widespread application in school buses for recording of interior bus activities while protecting the camera with a metal vandal resistant shell. Vandal resistant qualities include built in microphone, metal shell or casing, metal shoulder and metal base for a very durable camera. Steel adjustment set screws provided making it rock solid when locked down and much less likely to be bumped out of adjustment during hostile assaults by children or in some cases prisoners as we have offered this camera to several prisoner transport services with zero complaints or damage to date. High Definition 720P-AHD with a very wide angle 2.5 mm for rear of school bus or stairwell / driver camera offering an exceptional Field of View  for all other applications in a large vehicle like school bus front camera, school bus middle camera, transit bus or train. Built in audio recording, with customer adjustable gain on audio amplifier, light sensor automatically switches the camera from color in normal ambient light to Night Vision via IR LEDS in low light environments.

ExCAM-A  Exterior  Side & Rear Turret  Camera

ExCAM-A is a weatherized IP67 rated vandal resistant‚ auto activating, infrared camera that can easily adjust to point in almost any direction‚ without need to disassemble the camera housing or worry about back reflection from the IR illuminators. It is the size and shape of a very small dome camera‚ but its versatile “turret” style system allows for faster installs and easier adjustments. ExCAM-A permits quick adaptation for Side vehicle camera with horizon leveling for proper image view, or conventional horizontal image for proper video playback from Side View camera applications. High Definition 720P-AHD with a choice of 2 lenses for different applications in a vehicle: very wide angle 2.1 mm for rear view, or 12mm for Stop Arm Camera application on school buses or other applications concerned with capture of license plates on passing cars. A Rear Vision version is availabel with Mirror image to be used as a backup camera.

PD2-A Camera (Optional)

Dual Lens version of the above PD-A camera, for use as a Forward Road facing camera, and Driver camera in a single unit. Forward Road Facing camera has 3.6mm lens, IR LEDs disabled to prevent “ghosting” when the IR light is reflected back into the lens and creates a fog-like refraction that degrades image clarity. Sun Shield included for use in the forward facing lens to block unwanted sun that can cause glare in the early morning or late afternoon.

High Definition 720P-AHD, with Driver facing very wide angle 2.5 mm lens that provides an exceptional wide Field of view. The built in audio on the Driver Facing camera is very clear and the light sensor automatically switches the camera from color in normal ambient light to Night Vision via IR LEDS in low light environments.
