The Gatekeeper 508HD4a is an 8 channel (8 AHD / NTSC analog, 4 IP) video/audio recorder. The eight analog channels can be configured as either AHD or NTSC channels. When configured for eight NTSC analog channels, each channel will record a maximum of 30 FPS simultaneously with independently selectable resolutions and 8 quality levels. When eight channels are configured for AHD, the DVR will support 22 FPS each at 720p or 10 FPS each at 1080p. Analog High Definition camera utilizes Gatekeepers standard analog cables. This allows vehicles with existing analog compatible cabling to be easily updated to high definition cameras.
The 508HD4a DVR supports the AHD-M video standard. When combined with Gatekeeper’s S32AHD camera, video resolution is increased from standard D1 (720×480) to 1080p (1920×1080) high definition resolution. The 508HD4a DVR also supports the 960H (928×480) video standard.
The 508HD4a DVR also supports 2TB of storage in spinning hard drives or SSD drive formats.
The 508HD4a incorporates many features that dramatically increase the reliability of the DVR and the availability of recorded video. A custom file system is used to record data to the hard drive. This file system has been designed so that video can be recovered under most scenarios.
The 508HD4a has a high capacity power supply. The power supply stores energy so that if the DVR loses power (when the engine is started or other high current draw electrical devices are turned on, such as air conditioners or hydraulic lifts), there is enough energy in the power supply to continue to power the internal circuits of the DVR for a short period of time. For example, when power to the DVR is lost the DVR closes the video files correctly and then power down into a safe low power state. This makes the DVR virtually immune to the notorious unreliable power found in vehicles.
The 508HD4a has a latched door that prevents users from inadvertently removing the Caddy (hard drive carrier) before powering down the DVR. The key must first be turned to the unlock position before the door can be unlatched and opened and the caddy can be removed. When the door is unlatched and opened, the DVR shuts down, and it is safe to remove the Caddy. After the Caddy is reinserted, and the door is closed and latched, the DVR reboots and is once again ready to record.
The 508HD4a DVR passes MIL SPEC 810F (Trucks on Streets) for shock and vibration. In addition, Gatekeeper has developed and subjected the Gatekeeper DVRs to custom shock and vibration profiles. These profiles were derived by placing sensors on vehicles, and recording the shock and vibration that actual DVRs were subjected to in real world conditions.
DOWNLOAD OF VIDEO TO A USB DRIVE
The 508HD4a allows users to download video and/or video of marked events to a USB memory stick that can be inserted in the front of the DVR.
Wi-Fi AND AUTO WAKE READY
The 508HD4a is Wi-Fi Ready. Gatekeeper’s Wi-Fi system will provide radio coverage in a typical vehicle yard. Utilizing Wi-Fi 802.11n at 5GHz Gatekeeper offers both a rugged industrial rated access point and a Wi-Fi radio for the vehicle. Through the use of Auto Wake, a user can turn on the DVR and Wi-Fi radio in the vehicle so that video can be accessed.
DUAL STREAMING AND CELLULAR READY
The 508HD4a is dual streaming. This means a high quality full resolution image can be stored on the SD card while a lower resolution image can be streamed over the optional cellular connection.
