WatchGuard Video's 4RE HD Wireless In-Car Video System offers more than three times the image resolution of conventional systems. It first records onto an automotive-grade hard drive, and then onto a secure USB flash drive. Video files can be uploaded wirelessly using an industrial grade 802.11n antenna. File uploads, configuration updates, and firmware upgrades are fully automatic and "hands-free" to the officer. The system's high-fidelity wireless microphone records clear audio, which can be extremely important in capturing audio for evidence.
