Q. What is mobile DVR?
A. Mobile DVR solutions are RUGGED Digital Video Recorder systems that have been built SPECIFICALLY for TRANSIT / TRANSPORTATION based video surveillance. A mobile DVR (digital video recorder) has been specially designed for applications in buses, trucks, taxi, trams, metro, ambulance and other private vehicles.

Q. What is the difference between a regular DVR and mobile DVR? What is so special about the mobile DVR?
A. The main difference between a regular DVR and a mobile DVR lies in the environments in which they are meant to be used.

POWER SUPPLY – a regular DVR draws power from adaptor / indoor power supply
And has steady voltage – DC 12V and constant power supply. Whereas, a mobile DVR is powered by the vehicle & supports wide voltage input/ unstable voltage during engine start-up or braking when voltage falls to 8V or less or spikes up to as high as 36V.

ANTI-VIBRATION MECHANISM – a mobile DVR is constructed keeping in mind the Vibration which is inevitable in vehicles as they are constantly in motion; which may leads to mechanical failure.
The mobile DVR uses materials used for anti-vibration / shock-proof mechanisms.

DUST PREVENTION & HEAT DISSIPATION – a regular DVR is installed in open/well ventilated area and has simple design to dissipate heat working temperature range -10° ~50°C. A mobile DVR is made for installation in confined spaces and compartments where working temperature may ranges from -20° ~70°C and up to 95% humidity. The material & construct of the DVR allows heat dissipation and reduces dust from entering.

CONSTRUCT – a regular DVR utilizes BNC connector cable whereas the mobile DVR has aviation specification interface in place to combine devices- a rugged and solid Interface which ensures continuous transmission of power, signals and other data without failure.

DATA TRANSMISSION – regular DVR requires LAN connection / and recommended 4G/3G dongles for data transmission. Does not have GPS, or any secondary data storage option.
A Mobile DVR utilizes Wi-Fi, 4G & 3G networks, which enable real-time transmission of data collected from the vehicle in – video, location, speed and inertial measurements.

Q. What is the difference between a regular DVR and mobile DVR w.r.t remote monitoring?
