Mobile Digital CCTV Decoding
The
police service has an increasing requirement to download large volumes of
recorded CCTV video data from Digital Video Recorders (DVRs) for investigative
and evidential purposes. For more serious crimes, it is often not sufficient to
copy a short clip of video recording from a single camera onto a CD or DVD. The
entire contents of the DVR hard drive may need to be recovered. This may hold
several weeks' recordings amounting to 100s of Gigabytes or several Terrabytes
of data.
ClearView have enhanced their range of forensic video products with the DigiVac lab-in-a-bag. This has been developed to allow police technicians to download and decode large amounts of video data from most DVRs in the shortest time whilst maintaining evidential integrity. The system is configured to ensure all processes fully comply with the Home Office PSDB Digital Imaging Procedure guidelines.
The system is supplied in a single lightweight carry case. It comprises all the interconnection cables necessary to connect to a wide variety of different DVR interfaces including SCSI (68 and 80 pin), TCP/IP Ethernet LAN (10/100/1000M bandwidth), Wi-Fi, 3G, Firewire, USB2.0, infrared, modem (RJ-11), pier to pier and bluetooth.
A 3G mobile phone link allows users to connect to ClearView's support site for any feature or player support required on site.
The basic DigiVac system comprises a Terrabyte of hard drive storage as standard. This can be easily increased if required. Video data may be copied using the interface options listed above. Alternatively, disc cloning hardware is available to create a bit-for-bit copy of a complete DVR.
