NVR H series device user manual

NVR H is a network video recorder with HDMI output for home and office video surveillance. You can connect Ajax video devices and third-party IP cameras to the device.

Users can view archived and live footage in Ajax apps or on a display connected via the HDMI output. NVR H records the received data with corresponding settings and a hard disk drive or solid-state drive (not included). If the storage device is not installed, the video recorder is used only for integrating third-party IP cameras into the Ajax system. NVR H provides users with video alarm verification.

To set up NVR H, an internet connection is required. The video recorder connects to the Ajax Cloud service via Ethernet using the corresponding connector.

The device is available in several versions:

• NVR HAC (8-ch);

• NVR HAC (16-ch);

• NVR HDC (8-ch);

• NVR HDC (16-ch).

Operating principle

NVR H is a video recorder for connecting third-party IP cameras that have ONVIF and RTSP protocols and Ajax video devices. Allows you to install a storage device with a memory capacity of up to 16 TB (not included in the NVR H series package). Also, NVR H can work without a storage device.

How to choose a storage device

NVR H series features an HDMI output that allows video from connected cameras to be viewed on a display, even when the video recorder is not connected to the internet.

NVR H has two USB 2.0 (Type-A) ports for connecting a keyboard, mouse, or USB flash drive. The maximum output current is 500 mA per port. If the connected device requires more power to operate, provide an external power supply for that device.

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

NVR H series enables users to:

1. Add and configure IP cameras (camera resolution, brightness, contrast, etc.).

2. Watch video from added cameras in real-time, both locally and in Ajax apps, with the ability to zoom.

3. Watch and export videos from the archive locally and in Ajax apps, navigating by the recording chronology and calendar (if the storage device is connected to the video recorder).

4. Choose how to detect motion in the frame — on the camera or on the NVR H.

5. Configure motion detection on NVR H (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.

NVR H is designed for indoor installation. We recommend installing the video recorder on a flat horizontal or vertical surface for better heat exchange of the storage device. Do not cover it with other items.

Selecting the device location

It is advisable to choose an installation site where NVR H is hidden from prying eyes, for example, in the pantry. It will help to reduce the likelihood of sabotage. Note that the device is intended for indoor installation only.

The device is housed in a compact casing with active cooling. If NVR H is installed in insufficiently ventilated rooms, the operating temperature of the memory drive may be exceeded. Choose a hard, flat horizontal or vertical surface for mounting the casing, and do not cover it with other items.

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 NVR H

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

1. Remove SmartBracket from the video recorder by pulling down the back panel.

2. Secure SmartBracket to a hard, flat surface with the bundled screws. Use all fixation points.

3. Lift the 3.5″ drive latch.

   When replacing the hard disk drive (HDD), wait 10 seconds after disconnecting the device from the power source. The HDD contains rapidly rotating platters. Sudden movements or impacts can disable the mechanism, leading to physical damage and data loss.

   Do not move or flip NVR H until the HDD has stopped spinning.

   

4. Install the storage device in the NVR H enclosure so that the connectors match.

   

5. Lower the 3.5″ drive latch.

6. Secure the storage device in the NVR H enclosure with the bundled screw, using the location for fixation.

   

7. Connect external power supply and Ethernet connection. Turn on the power supply.

8. Add the device to the system.

9. Insert the video recorder into SmartBracket.

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

Adding to the system

Before adding a device

1. Install an Ajax app.

2. Log in to your 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.

Types of accounts and their rights

Adding to the space

1. Open the Ajax app. Select the space to which you want to add NVR H.

2. Go to the Devices tab and tap Add device.

3. Scan the QR code or enter it manually. Find the QR code on the back of the enclosure under the SmartBracket mounting 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 white.

8. Tap Add.

The connected device will appear in the list of devices in the Ajax app.

NVR H only works with one space. To connect the video recorder to the new space, remove NVR H from the device list of the old one. This must be done manually in the Ajax app.

Adding an IP camera to NVR H

You can calculate the number of cameras and NVRs that can be added to the space using the video device calculator.

The IP camera connected to the video recorder will appear in the list of NVR H cameras in the Ajax app.
