The Y35 HD v3 is a 5 channel (4 AHD, 1 IP) recorder. Each AHD and IP channel supports up to 1080P and up to 30 FPS simultaneously with independently selectable resolutions and 8 quality levels.

The Y35 HD v3 supports internal WiFi. Utilizing WiFi 802.11 a/n/ac dual-band at 2.4 GHz and 5GHz, Gatekeeper’s built-in WiFi can be configured to connect to an in-yard Access Point or act as an access point to allow DVR configuration using an Android tablet and Gatekeeper G4 Connect software.

The Y35 HD v3 supports one Conventional Magnetic Recording (CMR) hard drive or one SSD.

The Y35 HD v3 utilizes H.265 and H.264 video encoding. H.265 provides great video quality while producing 15% to 20% less data. That means longer record times.

Gatekeeper’s Y35 HD v3 high definition digital video recorder can combine with Gatekeeper’s G4 Vision software to allow vehicle fleet operation an on-command connection centralizing communications for system health check, driver behavior analysis, video management, live streaming video, GPS, routing and mapping, student tracking and other third-party software applications.



The Y35 HD v3 incorporates many features that dramatically increase the reliability of the DVR, and the availability of recorded video.

The Y35 HD v3 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 Y35 HD v3 has an electro-mechanical lock 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 to power down the DVR. The LEDs must be off before safely removing the caddy.


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.

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.


The Y35 HD v3 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 module.
