Cybersecurity Recommendations
Mandatory actions to be taken towards cybersecurity
1. 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.
2. 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.
“Nice to have” recommendations to improve your network security
1. Change Passwords Regularly
Regularly change the credentials to your devices to help ensure that only authorized users are able to
access the system.
2. 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 1025-65535. Avoiding the default ports
reduces the risk of outsiders being able to guess which ports you are using.
3. Enable HTTPS/SSL:
Set up an SSL Certificate to enable HTTPS. This will encrypt all communication between your devices
and recorder.
4. Enable IP Filter:
Enabling your IP filter will prevent everyone, except those with specified IP addresses, from accessing
the system.
5. Change ONVIF Password:
On older IP Camera firmware, the ONVIF password does not change when you change the system’s
credentials. You will need to either update the camera’s firmware to the latest revision or manually
change the ONVIF password.
6. Forward Only Ports You Need:
● Only forward the HTTP and TCP ports that you need to use. Do not forward a huge range of numbers
to the device. Do not DMZ the device's IP address.
● You do not need to forward any ports for individual cameras if they are all connected to a recorder on
site; just the NVR is needed.
7. Disable Auto-Login on SmartPSS:
Those using SmartPSS to view their system and on a computer that is used by multiple people should
disable auto-login. This adds a layer of security to prevent users without the appropriate credentials from
accessing the system.
8. Use a Different Username and Password for SmartPSS:

Cybersecurity Recommendations 3
In the event that your social media, bank, email, etc. account is compromised, you would not want
someone collecting those passwords and trying them out on your video surveillance system. Using a
different username and password for your security system will make it more difficult for someone to
guess their way into your system.
9. Limit Features of Guest Accounts:
If your system is set up for multiple users, ensure that each user only has rights to features and functions
they need to use to perform their job.
10. UPnP:
● UPnP will automatically try to forward ports in your router or modem. Normally this would be a good
thing. However, if your system automatically forwards the ports and you leave the credentials defaulted,
you may end up with unwanted visitors.
● If you manually forwarded the HTTP and TCP ports in your router/modem, this feature should be
turned off regardless. Disabling UPnP is recommended when the function is not used in real
applications.
11. SNMP:
Disable SNMP if you are not using it. If you are using SNMP, you should do so only temporarily, for
tracing and testing purposes only.
12. Multicast:
Multicast is used to share video streams between two recorders. Currently there are no known issues
involving Multicast, but if you are not using this feature, deactivation can enhance your network security.
13. Check the Log:
If you suspect that someone has gained unauthorized access to your system, you can check the system
log. The system log will show you which IP addresses were used to login to your system and what was
accessed.
14. Physically Lock Down the Device:
Ideally, you want to prevent any unauthorized physical access to your system. The best way to achieve
this is to install the recorder in a lockbox, locking server rack, or in a room that is behind a lock and key.
15. 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.
16. Isolate NVR and IP Camera Network
The network your NVR and IP camera resides on should not be the same network as your public
computer network. This will prevent any visitors or unwanted guests from getting access to the same
network the security system needs in order to function properly.

Maintenance 8
1Maintenance
1.1 Environmental Requirement
The video wall can only be installed indoors. It is recommended that the room where the
video wall is installed be equipped with air conditioner. The video wall cannot be operated
in environment with high humidity and heavy dust.
Do not block the vent of the video wall and the airflow around it; otherwise the temperature
of the video wall will increase, and fire might occur.
1.2 Maintenance Tips
Comply with the maintenance rule strictly to prolong the life span of the video wall and to
implement energy conservation and emission reduction.
Operating Time
Because of high temperature, electronic products will age rapidly if they are operated for a long
time. The relation of operating time and performance of the video wall is as follows. SeeFigure
1-1.
Figure 1-1 Performance
To prolong the life span of the video wall and save maintenance expenses, follow the
suggestions bellow.

Maintenance 9
If the video wall has worked for ten hours, turn it off and then turn it on after 15–30 minutes.
If the video wall has worked for 7×24 hours, turn it off and then turn it on after two hours.
Temperature, Humidity and Ventilation
The appropriate ambient temperature range for the video wall is 22℃±4℃, and the
appropriate relative humidity range is 30%–70%, no condensation. There must be no great
temperature and humidity difference.
If the video wall is used in environment with high temperature and humidity, there will be
tiny water drops on the surface and frame of the video wall. The water drops will flow inside
the video wall. As a result, the glass structure will be damaged, and the liquid crystal
molecule aggregation and outflow will occur. The phenomenon is displayed in Figure 1-2.
Figure 1-2 Liquid crystal leakage
During the operation, pay attention to the bellow points.
Before turning off the video wall, make sure that the temperatures of the air conditioners in
the server room and the room where the video wall is installed are the same.
If the video wall has been off for a long time, check if there are water drops on the surface.
If there are water drops, do not dry the surface with wet cloth. Dry the surface with
absorbent paper, do not plug it in, and contact the after-sales personnel.
Free quality assurance service is not applicable to damage (includes but not limited to the
damage to the video wall and damage to the user or the third party) results from incorrect using
and maintaining the video wall.
Cleaning
Use degreasing cotton or cloth to clean the screen.
The ideal detergent is isopropanol or n-hexane. Do not use ketone (like acetone) to clean
the screen.
Before you clean the screen, pull the plug out of the socket.
Wet cloth is not allowed to clean the video wall because there will be tiny water drops on
the surface and frame of the video wall. The water drops will flow inside the video wall. As a
result, the glass structure will be damaged, and the liquid crystal molecule aggregation and
outflow will occur.
The panel is fragile. As a result, you must not press or scratch the surface of the screen
with great force.

Maintenance 10
Power Supply
Stable 100V–240V single phase power supply is needed; otherwise the video wall cannot work
normally. To get stable voltage and prevent damage result from electrical surge, use the
stabilized voltage supply.
Storage Requirement
If the video wall will not be used for a long time, cover it with the dust-cloth.
If the video wall has not been used for over six months before you start to use it again, do
dust removal first, or contact professional company to do the maintenance.
If the video wall is not in use for a long time, it will gather dust and heat radiation will be
influenced.
Dust-Proof Requirement
During debugging and operation, the dust concentration of the working area should not exceed
10mg/m3.
If the video wall must be used in environment with high temperature and high humidity, or the
video wall must be in single display mode for a long time, we strongly recommend you to
contact engineers of our company to get suggestions. Otherwise the reliability and performance
could be greatly influenced.
Places like airports, banks and stock markets are places with great dust and temperature
difference and humidity difference.
