could void the user's authority to operate the equipment.

FCC conditions:

This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:

 This device may not cause harmful interference.
 This device must accept any interference received, including interference that may cause

undesired operation.

FCC compliance:

This equipment has been tested and found to comply with the limits for a digital device,
pursuant to part 15 of the FCC Rules. This equipment generate, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the guide, may cause
harmful interference to radio communication.

 For class A device, these limits are designed to provide reasonable protection against

residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

 For class B device, these limits are designed to provide reasonable protection against

harmful interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:

 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

 Consult the dealer or an experienced radio/TV technician for help.

Regulatory Information I

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

Cybersecurity Recommendations II

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.

2.3.5.2 Obtain Connection Modes of the Main Power Switch

In order to ensure correct cable connection, it is necessary to obtain the connection mode of
the main power switch through three methods (is the main power switch connected to the
positive or negative pole of the battery?).

 Ask the vehicle manufacture the connection modes of the main power switch of the

vehicle.

 Measure with a multimeter: disconnect the main switch, then measure the voltage between

the vehicle body and the positive pole of the vehicle battery. If the voltage is 12V or 24V, it
means that the main switch disconnects the positive pole. If the voltage is 0V, then the
main switch disconnects the negative pole.

 Visual inspection: whether the switch cable near the vehicle battery is connected to the

positive pole or the negative pole.

2.3.5.3 Connecting Operation

The driving recorder must be connected to the ground wire. ACC signal, and constant
electricity.

Enable the main power switch on the vehicle, place the key in the OFF state, and then Step 1

measure the normal live electricity of the vehicle.
Use a multimeter to measure the voltage on the fuse by switching to the DC voltage
range. When the multimeter detects voltage, it measures the normal live electricity on
the vehicle. Generally, the voltage is 24V DC for large vehicles and 12V DC for small
vehicles. However, this is subject to actual data.

When the vehicle key is placed at the ACC state or the ON state, the ACC signal of the Step 2

vehicle is measured.

Dimension and Installation 17

Use a multimeter to measure the voltage on the fuse by switching to the DC voltage
range. When the multimeter detects voltage, remove the car key. If the voltage changes
to 0V, it means that the measured signal is ACC on the car.

Turn off the main power switch on the vehicle, and place the key in the OFF state. Step 3
Connect the power cable according to the main power switch installation mode. See Step 4

Figure 2-23 and Figure 2-24.

CAUTION

 Before connecting with power cord, select proper fuse. 7.5A fuse is

recommended.

 The positive and negative poles of the battery must be equipped with protective

devices such as fuses.

 For vehicles where the master power switch is installed at the cathode of the

accumulator, isolation installation is needed.
