VI
Operation and Maintenance Requirements
Do not touch the heat dissipation component of the unit. This part of the unit is hot and
may cause a burn.
Do not open or dismantle the device; there are no components that a user can fix or
replace. Opening the unit may cause water leakage or expose components to direct light.
Contact the manufacturer or a qualified service representative to service the camera or to
replace a component, including the desiccant.
Dahua recommends the use of a thunder-proof device in concert with the unit.
Do not touch the CCD or the CMOS optic sensor. Use a blower to clean dust or dirt on the
lens surface. Use a dry cloth dampened with alcohol and gently wipe away any dust on
the lens.
Use a dry soft cloth to clean the unit’s housing. If the unit is particularly dusty, use water to
dilute a mild detergent, apply the diluted detergent to a soft cloth, then gently clean the
device. Finally, use a dry cloth to wipe the unit dry. Do not use a volatile solvent like
alcohol, benzene, or thinner; or use a strong detergent with abrasives, which may damage
the surface coating or reduce the working performance of the unit.
Do not touch or wipe a dome cover during installation, this cover is an optical device.
Refer to the following methods clean the dome cover:
Stained with dirt: Use an oil-free soft brush or blower to gently remove the dirt.
Stained with grease or fingerprints: Use a soft cloth to wipe gently the water droplet or the
oil from the dome cover. Then, use an oil-free cotton cloth or paper soaked with alcohol or
detergent to clean the lens from the center of the dome to outside. Change the cloth
several times to ensure the dome cover is clean.
WARNING
Modify the default password after login.
Use attachments and accessories only specified by the manufacturer. Any change or
modification of the equipment, not expressly approved by Dahua, could void the warranty.
Internal and external ground connection should be stable.
Do not supply power via the Ethernet connection (PoE) when power is already supplied
via the power connector.
Disconnect power before device maintenance and overhaul. It is prohibited to open the
cover with power on in an explosive environment.
Please contact the local dealer or the nearest service center if the device fails to work
normally, please don’t dismantle or modify the device.

Cybersecurity Recommendations VII
Cybersecurity Recommendations
Mandatory actions to be taken towards cybersecurity
Change Passwords and Use Strong Passwords
The number one reason systems get “hacked” is due to having weak or default
passwords. It is recommended to change default passwords immediately and choose
a strong password whenever possible. A strong password should be made up of at
least 8 characters and a combination of special characters, numbers, and upper and
lower case letters.
Update Firmware
As is standard procedure in the tech-industry, we recommend keeping NVR, DVR,
and IP camera firmware up-to-date to ensure the system is current with the latest
security patches and fixes.
Recommendations to improve your network security
Change Passwords Regularly
The length should be greater than 8 characters;
Include at least two types of characters; character types include upper and lower case
letters, numbers, and symbols;
Do not use an account name or the account name in reverse order;
Do not use sequential characters, such as 123, abc, etc.;
Do not use repeated characters, such as 111, aaa, etc.;
Change Default HTTP and TCP Ports
Change default HTTP and TCP ports for systems. These are the two ports used to
communicate and to view video feeds remotely.
These ports can be changed to any set of numbers between 1025 and 65535.
Avoiding the default ports reduces the risk of outsiders being able to guess which
ports you are using.
Update Firmware and Client Software
Keep your network-enabled equipment (such as NVRs, DVRs, IP cameras, etc.)
firmware up-to-date to ensure the system is equipped with the latest security patches
and fixes. When the equipment 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.
Download and use the latest version of client software.
Enable HTTPS/SSL
Set up an SSL Certificate and enable HTTPS to encrypt all communication between
your devices and recorder.
Enable IP Filter
Enable the IP filter to prevent unauthorized access to the system.

Cybersecurity Recommendations VIII
Change ONVIF Password
Older IP camera firmware does not automatically change the ONVIF password when
the system credentials are changed. Update the camera’s firmware to the latest
revision or manually change the ONVIF password.
Forward Only Ports You Need
Forward only the HTTP and TCP ports that are requited. Do not forward a wide range
of numbers to the device. Do not DMZ the device's IP address.
Do not forward any ports for individual cameras if they are all connected to a recorder
on site. Simply forward the NVR port.
Disable Auto-Login on SmartPSS
Disable the Auto-Login feature on SmartPSS installed on a computer that is used by
multiple people. Disabling auto-login prevents users without the appropriate
credentials from accessing the system.
Use a Different Username and Password for SmartPSS
Do not a username/password combination that you have in use for other accounts,
including social media, bank account, or email in case the account is compromised.
Use a different username and password for your security system to make it difficult for
an unauthorized user to gain access to the IP system.
Limit Features of Guest Accounts
Ensure that each user has rights to features and functions they need to perform their
job.
Disable Unnecessary Services and Choose Secure Modes
Turn off specific services, such as SNMP, SMTP, and UPnP, to reduce network
compromise from unused services.
It is recommended to 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 a mailbox server.
FTP: Choose SFTP and use strong passwords.
AP hotspot: Choose WPA2-PSK encryption mode and use strong passwords.
Multicast
Multicast is used to share video streams between two recorders. Currently there are
no known issues involving Multicast. Deactivate this feature if not in use to enhance
network security.
Check the Log
The information stored in the network log file is limited due to the equipment’s limited
storage capacity. Enable the network log function to ensure that the critical logs are
synchronized to the network log server if saving log files is required.
Check the system log if you suspect that someone has gained unauthorized access to
the system. The system log shows the IP addresses used to login to the system and
the devices accessed.
Physically Lock Down the Device
Perform physical protection to equipment, especially storage devices. For example,
place the equipment in a special computer room and cabinet, and implement access
control permission and key management to prevent unauthorized personnel from
accessing the equipment.

Cybersecurity Recommendations IX
Connect IP Cameras to the PoE Ports on the Back of an NVR
Cameras connected to the PoE ports on the back of an NVR are isolated from the
outside world and cannot be accessed directly.
Isolate NVR and IP Camera Network
Ensure that the network for the NVR and IP cameras should not be the same network
as a public computer network. Separate networks prevent unauthorized users
accessing the same network the security system.
Secure Auditing
Check online users regularly to ensure unauthorized accounts are not logged in to a
device.
Check the equipment log to access the IP addresses used to login to devices and
their key operations.
