measures which include but not limited to using strong password, changing password regularly,
upgrading firmware to the latest version, and isolating computer network. For some devices with

changing the system password, and you need to upgrade the firmware or manually change the
ONVIF password.
Use standard components or accessories provided by manufacturer and make sure the device is
installed and maintained by professional engineers.
Do not expose the surface of the image sensor to laser beam radiation in an environment where
a laser beam device is used.
Do not provide two or more power supply sources for the device unless otherwise specified. A
failure to follow this instruction might cause damage to the device.
