3 Installation

3.1 Installing Device

The device supports standard rack mount.

Install the rack mount kit on both sides of the switch.

3.2 Wiring

3.2.1 Connecting GND

Figure 3-2 GND terminal

The sectional area of the GND cable shall be more than 2.5 mm ^4 , and the GND resistance shall be less than 4 .

3.2.2 Connecting Power Cord

Before connecting the power cord, make sure that the device is reliably grounded.

Step 1 Connect one end of the power cord into the power jack of the device accurately.

Step 2 Connect the other end of the power cord to the external power socket.

3.2.3 Connecting Ethernet Port

Figure 3-3 Ethernet port pin number

8 7 6 5 4 3 2 1

10/100/1000 M Base-T Ethernet port adopts standard RJ-45 port. Equipped with self-adaptation function, it can be automatically configured to full duplex/half-duplex operation mode, and supports MDI/MDI-X self-recognition function of the cable, which means that the switch can use cross-over cable or straight-through cable to connect terminal device to network device.

When connecting to a non-PoE device, the device needs to be used with an isolated power supply.

3.2.4 Connecting SFP Port

Before installing SFP module, wear antistatic gloves, and then wear antistatic wrist strap. Make sure that the antistatic gloves and the antistatic wrist strap are in good contact.

Step 1 Lift the handle of SFP module upward vertically, and stuck it to the top hook.

Step 2 Hold the SFP module by both sides, and push it gently into the SFP slot till the SFP module is firmly connected to the slot (both the top and bottom spring strip of the SFP module are firmly stuck with the SFP slot).

WARNING

The signal is transmitted through laser by optical fiber cable. The laser conforms to the requirement of level 1 laser products. To avoid injury of eyes, do not look at the 1000 Base-X optical port directly when the device is powered on.

4 Device Login

You can log in to the device through WEB for management and operation.

Step 1 In the browser address bar, enter the IP address of the device (192.168.1.110 by default).

Step 2 Enter the username and password (both are admin by default).

Step 3 Click Login.

For first login, you need to change the password according to the interface prompt.

Appendix 1 Cybersecurity Recommendations

Cybersecurity is more than just a buzzword: it's something that pertains to every device that is connected to the internet. IP video surveillance is not immune to cyber risks, but taking basic steps toward protecting and strengthening networks and networked appliances will make them less susceptible to attacks. Below are some tips and recommendations on how to create a more secured security system.

Mandatory actions to be taken for basic device network security:

1. Use Strong Passwords

Please refer to the following suggestions to set passwords:

• The length should not be less than 8 characters;
• Include at least two types of characters; character types include upper and lower case letters, numbers and symbols;
• Do not contain the account name or the account name in reverse order;
• Do not use continuous characters, such as 123, abc, etc.;
• Do not use overlapped characters, such as 111, aaa, etc.;

2. Update Firmware and Client Software in Time

• According to the standard procedure in Tech-industry, we recommend to keep your device (such as NVR, DVR, IP camera, etc.) firmware up-to-date to ensure the system is equipped with the latest security patches and fixes. When the device is connected to the public network, it is recommended to enable the "auto-check for updates" function to obtain timely information of firmware updates released by the manufacturer.
• We suggest that you download and use the latest version of client software.

"Nice to have" recommendations to improve your device network security:

1. Physical Protection

We suggest that you perform physical protection to device, especially storage devices. For

. . . . . . . . . . . . . . . . . . . .

6. Enable HTTPS

We suggest you to enable HTTPS, so that you visit Web service through a secure communication channel.

7. MAC Address Binding

We recommend you to bind the IP and MAC address of the gateway to the device, thus reducing the risk of ARP spoofing.

8. Assign Accounts and Privileges Reasonably

According to business and management requirements, reasonably add users and assign a minimum set of permissions to them.

9. Disable Unnecessary Services and Choose Secure Modes

If not needed, it is recommended to turn off some services such as SNMP, SMTP, UPnP, etc., to reduce risks.

If necessary, it is highly recommended that you use safe modes, including but not limited to the following services:

• SNMP: Choose SNMP v3, and set up strong encryption passwords and authentication passwords.
• SMTP: Choose TLS to access mailbox server.
• FTP: Choose SFTP, and set up strong passwords.
• AP hotspot: Choose WPA2-PSK encryption mode, and set up strong passwords.

10. Audio and Video Encrypted Transmission

If your audio and video data contents are very important or sensitive, we recommend that you use encrypted transmission function, to reduce the risk of audio and video data being stolen during transmission.

Reminder: encrypted transmission will cause some loss in transmission efficiency.

11. Secure Auditing

• Check online users: we suggest that you check online users regularly to see if the device is logged in without authorization.
• Check device log: By viewing the logs, you can know the IP addresses that were used to log in
