Precautions for Safe Use
Power Supply and Wiring
• Make sure to use the product with the power supply voltage specified by the user manual.
• Do not connect camera to AC power. Applying AC power will cause the unit to fail.
• Use a wire size suitable to the current consumption and length of wire.
• Use a DC power supply with safety measures against high-voltage spikes (safety extra low-voltage
circuits on the secondary side). If the system must meet UL standards, use a UL Class 2 power supply.
• Confirm that the following conditions are met before applying power to the camera:
• Correct voltage and polarity;
• Proper load and output wiring;
• All wiring is correct for the application.
• When using equipment that is connected to an AC power source such as an AC adapter or PoE
injector, use it within the rated voltage range. Usage with a voltage higher than what it is rated for
may cause serious personal injury due to electric shock, or serious physical damage due to fire or
equipment failure. Do not touch any part of the device while in operation, or immediately after turning
OFF the power.
• Be careful when connecting cables. Pinching or other injury may occur.
Ground
• Ensure that the power supply circuit of the unit is insulated from the internal circuit. Refer to the user manual.
• Check wiring again before turning on the unit.
Security Measures
 Anti-Virus Protection
Install the latest commercial-quality antivirus software on the computer connected to the control system
and maintain to keep the software up to date.
 Security Measures to Prevent Unauthorized Access
Take the following measures to prevent unauthorized access to our products:
• Install physical controls so that only authorized personnel can access control systems and
equipment.
• Reduce connections to control systems and equipment via networks to prevent access from
untrusted devices.
• Install firewalls to shut down unused communications ports and limit communications hosts and
isolate control systems and equipment from the IT network.
• Use a virtual private network (VPN) for remote access to control systems and equipment.
• Adopt multifactor authentication to devices with remote access to control systems and equipment.
• Set strong passwords and change them frequently.
• Scan for viruses to ensure safety of USB drives or other external storage devices before connecting
them to control systems and equipment.
 Data Input and Output Protection
Validate backups and ranges to cope with unintentional modification of input/output data to control
systems and equipment.
• Check the scope of data.
• Check validity of backups and prepare data for restore in case of falsification or abnormalities.
• Safety design, such as emergency shutdown and fail-soft operation in case of data tampering or
abnormalities.
