NOTE

This camera supports both IP (wired) and WiFi (wireless) connectivity. Steps 2 thru 4 below guide you for activating the camera and configuring its network parameters for a wired connection. If using the camera exclusively in wireless mode, please refer to the camera firmware user manual activating the camera and configuring its network parameters, and then continue here with Step 5.

Step 2. Install the Alibi Config Tool software

NOTE: If the camera LAN extension cable is attached to a Network Video Recorder (NVR) internal switch, skip this step.

The Alibi Config Tool is a PC-based network utility for discovery of Alibi compatible devices. It provides an easy way to activate devices, configure camera and recorder network configuration settings, and set device passwords. It can be installed on a Microsoft® Windows® operating system that has direct access to the network where your Alibi devices are installed. You can download the Alibi Configuration Tool from Supercircuits.com or AlibiSecurity.com/Resources.

1. Download the Alibi Config Tool from the Supercircuits.com or AlibiSecurity.com/Resources website. At the time when this document was published, the file is named: alibi-config-tool.zip and is about 80MB.
2. Un-zip the file on a computer with Microsoft Windows (Windows 10 or newer) that is connected to the LAN where your Alibi camera is connected.
3. Run the file contained in the zip file: Alibi Config Tool.exe. Follow the on-screen instructions to install the file.
4. Open the Alibi Config Tool application. When the application opens, it automatically “discovers” and lists all Alibi compatible devices on the LAN. See below.
   
   Notice: In the screen above, the tool discovered devices with IP addresses of 192.168.0.xxx and 192.168.3.xxx. It will also list other Alibi compatible devices on the LAN, and devices with the address 192.168.1.64 (an inactive Alibi device).

Step 3. Activate Inactive Alibi device

NOTE: If the camera LAN extension cable is attached to a Network Video Recorder (NVR), skip this step.
Refer to the documentation available for your NVR firmware for the procedure to activate the camera, if necessary.

When an Alibi device is first installed, or reset to its factory configuration, it must be “Activated” before it can be used. In the Alibi Configuration Tool, “Inactive” devices have a Security status of Inactive, and an IPv4 address of 192.168.1.64. A device is “Activated” when a password is assigned to the admin username of the device.

In the example below, an ALI-NS1025VR camera is activated and configured for its network. The procedure is similar for all other Alibi network cameras currently available.

1. Scan through the list of devices the Alibi Config Tool discovered for the Inactive device you want to activate (see below). Click on the device in the list to highlight it, and then click the select box to check it. See below.
   

2. Click the Activate button. In the Activate window, you will create a password for the admin (administrator) username.

a. In the Activate window, enter an a password for admin in the New Password field. Include a combination of uppercase, lowercase alphabetic characters and numbers to create a “Strong” password. The rating is shown beneath the field. See above.
b. Enter the admin password again in the Confirm field, and then click Activate. In the screen below, notice that the device Security status shows “Active”. Record your admin password
for reference later.

CAUTION
If you lose your admin (administrator) password, you cannot configure the device or restore it to its factory settings. To reset your password, call your support organization for specific instructions.

Notice that although the device is now activated, it retained the default IP address.

Step 4. Modify Network Parameters

NOTE: If the camera LAN extension cable is attached to a Network Video Recorder (NVR), skip this step.
The camera will receive network configuration settings from the NVR. Refer to the documentation available for your NVR firmware for more information.

You can change the network parameters of devices that are active.

1. In the list of devices discovered, click on the device you want to change the network settings for, and then click the select box to check it. See below.
   

2. In the popup window, edit the current network parameters, and then enter the admin user password in the field at the bottom.
   a. Enable DHCP: You can select Enable DHCP to acquire compatible network settings from a DHCP server installed on the LAN. However, these settings can be changed by the DHCP server. Since it is recommended to use an unchanging IP address, you can use DHCP to acquire compatible network settings, and then uncheck Enable DHCP and save that configuration to retain the new network parameters.
   b. In the example below, the IPv4 address was changed to 192.168.3.100, and the IPv4 Gateway was changed to 192.168.3.1. The Subnet Mask here did not need to change. These settings were determined to be compatible with the network router and other devices that share the same router.
   

3. Click OK to save your settings. The parameter change(s) will be shown device’s network parameters (see below).
   

Step 5. Login to the camera

NOTE: If the camera LAN extension cable is attached to a Network Video Recorder (NVR), skip this step. Microsoft® IE is used to access your camera remotely. IE must run as an Administrator to use all features available through a remote login to the camera.
