G4-816HD - 16 Channel Recorder, 240 FPS, 720 x 480 Resolution
Gatekeeper's 816HD is a 240 frame per second, H.264, sixteen channel, D1 resolution, fan less, hard drive based recorder that will record up to 16 analog cameras with audio simultaneously. The maximum frame rate for any video channel is 30 FPS and each video channel independently supports selectable video resolutions and 9 quality settings.
The Comrad supports dual hard drives for a combined capacity up to 4TB.
The 816HD 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. Optionally the 816HD is available with an external battery that behaves as an uninterruptible power supply (UPS) The battery stores energy so that if the DVR loses power (when the engine is being started or other high current draw electrical devices are turned on, such as air conditioners or lifts) there is enough energy in the battery to continue to supply power to the internal circuits of the DVR for a short period of time. This makes the DVR virtually immune to the notoriously unreliable power found in vehicles.
The 816HD has a keyed electrical interlock that prevents users from inadvertently removing the Comrad (hard drive carrier) before powering down the DVR. The key must first be turned to unlock position before the Comrad can be removed. When the key is in the unlocked position the DVR stops recording and it is safe to remove the Comrad.
After the Comrad is reinserted, and the key is moved to the locked position the DVR is once again ready to record.
The Comrad (hard drive carrier) 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 obtained 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 Comrad can be equipped with a 256GB Solid State Hard Drive.
The Comrad contains an advanced thermal management system that heats up the hard drive to its prescribed operating temperature before spinning it up in cold weather.
Download of Video to a USB Drive
The 816HD 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 816HD is WiFi Ready. Gatekeepers 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
