CP4S: 4-Channel HD Vehicle DVR

Nearly 360-degree visibility across four camera angles.


Protect your drivers and business from false claims with the full picture that the SmartWitness CP4S 4-channel vehicle DVR provides.

This four-channel connected vehicle DVR operates with ultrafast 4G/LTE, uploading data 10x faster than 3G devices. With instant notification of safety-critical events and real-time location and behavior tracking, commercial vehicle owners can respond quickly when issues arise.

The CP4S vehicle DVR supports up to four SmartWitness HD (720p) cameras for crystal-clear video on all channels. Add an in-cab monitor to increase driver visibility and safety. With a nearly 360-degree view, the video tells the complete story of any incidents, quickly resolving insurance claims and exonerating drivers.

A compact, commercial-grade design makes the CP4S a fit in virtually any vehicle. Next-generation data security, automatic system health checks and protection from power disruptions keep data secure and available on demand 24/7. A Wi-Fi-only version (CP4S-W) is also available, which is perfect for existing network environments.

The CP4S is certified on Verizon, AT&T and UScellular networks (FirstNet pending).

The CP4S is a powerful, compact and discreet product that provides the ability to have up to 4 HD cameras, giving fleet managers and drivers nearly 360-degree vehicle visibility awareness. The CP4S records second-by-second data on the onboard SD card and, if an incident occurs, gathers the 10 seconds before and after the incident and sends it to the cloud for immediate viewing. This saves time and focuses the customer's attention on what needs to be seen, as opposed to sifting through hours of footage of drivers doing exactly what they should be doing.

While the law presumes innocence, commercial drivers are often assumed guilty on the scene. The incident video serves as valuable evidence, revealing the truth of what happened and protecting drivers from many of the issues faced on the roads today: insurance fraud, staged accidents, false/exaggerated whiplash claims, conflicting reports of actual events, driving offense allegations (speeding, traffic signal violations, swerving, distracted driving, etc.).
