The G4-504HD2a is a 6 channel (4 AHD, 2 IP) recorder. Each analog channel will record 10 FPS simultaneously with independently selectable resolutions quality levels. The 504HD2a supports hard drives sizes up to 2TB and SSD up to 2TB.
Superb Reliability
The G4-504HD2a incorporates many features that dramatically increase the reliability of the DVR, and the availability of recorded video.
The G4-504HD2a 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 G4-504HD2a 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.
Built Rugged
The Caddy incorporates a shock and vibration system to protect the hard drive. It has passed 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.
For the ultimate in hard drive reliability, the Caddy can be equipped with a 2TB Solid State Hard Drive.
The Caddy contains an advanced thermal management system that heats up the hard drive to its prescribed operating temperature, before writing or reading data in cold weather.
Download of Video to a USB Drive
The G4-504HD2a allows the user to download video, and/or video of marked events, to a USB memory stick that can be inserted in the front of the DVR.
WiFi and Auto Wake Ready
The G4-504HD2a is WiFi Ready. Gatekeeper’s WiFi system will provide radio coverage in a typical vehicle yard.
Utilizing WiFi 802.11n at 5GHz, Gatekeeper offers both a rugged industrial rated access point, and a WiFi radio for the vehicle. Through the use of Auto Wake, a user can turn on the DVR and WiFi radio in the vehicle, so that video can be accessed.
Dual Streaming and Cellular Ready
The 504HD2a is dual streaming. This means a high quality full resolution image can be stored on the Caddy, while a lower resolution image can be streamed over the optional cellular connection.
