Operating principle

The Ajax Superior NVR H2DAI2GAC series includes network video recorders for connecting Ajax video devices and third-party IP cameras that support ONVIF and RTSP protocols. The NVR allows you to install two hot-swapped storage devices with a memory capacity of up to 24 TB (not included in the NVR complete set).

The video recorders support two video recording modes:

• Redundancy mode is a mode in which the NVR records the same video streams simultaneously to both storage devices, ensuring data redundancy and reliability.
• Split mode is a mode in which the NVR sequentially distributes video streams across multiple storage devices to balance load and optimize storage.

Use storage devices of the same capacity when the video recorder operates in redundancy mode. Otherwise, the total recording capacity will be limited by the smallest drive.

Using the video storage calculator, you can calculate the Ajax Superior NVR H2DAI2GAC series required storage capacity and estimated recording time based on the settings.

Ajax Superior NVR H2DAI2GAC series devices connect to cameras through an external network switch. In this configuration, the switch provides network connectivity and power delivery (if it supports PoE). The devices also feature an HDMI output, which allows you to view video from connected cameras on a display even when the video recorder is not connected to the internet. The NVRs are equipped with one USB 3.0 (Type-A) port and two USB 2.0 (Type-A) ports for connecting a keyboard, mouse, USB flash drive, or USB Audio Device Class device (Audio IN/Audio OUT). The maximum output current is 900 mA per USB 3.0 port and 500 mA per USB 2.0 port. If a connected device requires more power, use an external power supply.

The video recorders feature a built-in accelerometer that detects if the device has been moved. When the accelerometer is activated, the system sends a notification that the device has been moved once it detects any change in the device’s position. This feature can be configured in the Tampering attempt notifications settings of the device.

Ajax Superior NVR H2DAI2GAC series enables users to:

NVR H2DPAC series enables users to:

1. Add and configure IP cameras (camera resolution, brightness, contrast, etc.).
2. Watch video from added cameras in real-time with the ability to zoom.
3. Watch and export videos from the archive, navigating by the recording chronology and calendar (if a storage device is connected to the video recorder).
4. Choose how to detect motion in the frame — on the camera or on the video recorder.
5. Configure motion detection on the video recorder (detection zones, sensitivity level).
6. View the Video wall that combines images from all connected cameras.
7. Create video scenarios that send a short video from the selected camera to the Ajax app when the detector is triggered.
8. Configure connection via ONVIF to integrate the device with video management systems (VMS) such as Milestone, Genetec, Axxon, and Digifort.
9. Create local users and manage their access to the cameras and recorded videos.
10. Watch videos in real time and playback recorded videos locally on a display connected to the video recorder via the HDMI output.
11. Configure specific video recorder settings locally.

The video recording segments downloaded from the video recorder have the Ajax digital signature that verifies the integrity of the exported video. To verify the authenticity of the downloaded video recordings, use the Ajax Media Player software.

Selecting the device location

It is recommended to place the video recorder installed on rack-mount brackets inside a locked cabinet or server rack hidden from prying eyes. This will help to reduce the likelihood of sabotage. Ensure that the cabinet provides access for service and proper cable management. Note that the device is intended for indoor installation only.

The device is housed in a compact casing with active cooling. If the rack cabinet has insufficient ventilation or airflow, the operating temperature of memory drives may be exceeded. Install the video recorder on a flat, stable rack shelf or use rack-mount brackets attached to the rack rails. Ensure that the ventilation openings are not obstructed.

Follow placement recommendations when designing the Ajax system for an object. The security system should be designed and installed by professionals. The list of authorized Ajax partners is available here.

Where not to install the video recorder

1. Outdoors. This may cause the breakdown of the video recorder.
2. Inside premises with temperature and humidity values that do not correspond to the operating parameters.

Installation

Before installing the video recorder, ensure that you have chosen the optimal location that complies with the requirements of this manual.

The video recorder is designed to be installed in a server rack or on a flat, stable surface.

1. If you plan to mount the video recorder in a server rack, install the rack-mount brackets using the fixing points on the sides of the video recorder.
2. Install the video recorder in a server rack or on a flat, stable surface, following the installation recommendations.
3. Remove the front panel by sliding it to the right.
4. Press the latch and pull the storage device tray out.
5. Install the storage device in the drive tray, aligning the mounting holes on the drive with those on the tray. Secure the storage device with the bundled screws using the designated mounting holes.
6. Insert the storage device tray back into the NVR slot.
7. Repeat the procedure for the second storage device tray if necessary.
8. Install the front panel by sliding it back into place.
9. Connect the power cable.
10. Connect the video recorder to the network via the Ethernet port.
11. Connect the cables to the Ethernet input and output ports.
12. If necessary, connect a display to the HDMI port and interface devices to the USB ports.
13. Turn on the power switch to activate the device.
14. Add the device to the system.

The LED indicator lights up yellow and turns white after the internet is established. If the connection to the Ajax Cloud server fails, the LED indicator lights up red.

Adding to the system

Only verified partners can add and configure Ajax Superior devices in Ajax PRO apps.

Types of accounts and their rights

Before adding a device

1. Install an Ajax PRO app.
2. Log in to your PRO account or create a new one.
3. Select a space or create a new one.
4. Add at least one virtual room.
5. Ensure the space is disarmed.

Adding to the space

1. Open the Ajax PRO app. Select the space to which you want to add Ajax Superior NVR H2DAI2GAC series.
2. Go to the Devices tab and tap Add device.
3. Scan the QR code or enter it manually. Find the QR code under the removable front panel and on the packaging.
4. Assign a name to the device.
5. Select a virtual room.
6. Tap Add.
7. Make sure that the video recorder is powered on and has access to the Internet. The LED indicator should light up white.
8. Tap Add.
