Cautions
• If the camera fails to synchronize the local time with that of the
network, you need to set the camera time manually. Visit the camera
(via web browser or client software) and enter the system settings
interface for the time settings.
• Make sure the power supply voltage is correct before using the
camera.
• Do not drop the camera or subject it to physical shock.
• Do not touch sensor modules with fingers. If cleaning is necessary,
use a clean cloth with a bit of ethanol, and wipe it gently. If the
camera will not be used for an extended period, use the lens cap to
protect the sensor.
• Do not aim the camera at the sun or extra bright places. Blooming or
smearing may occur otherwise (which is not a malfunction) and
affect the endurance of the sensor at the same time.
• The sensor may be burned out by a laser beam, so if any laser
equipment is in use, make sure that the surface of the sensor will not
be exposed to the laser beam.
• Do not place the camera in extremely hot, cold (the operating
temperature shall be -30°C to +60°C), dusty, or damp locations, and
do not expose it to high electro-magnetic radiation.
• To avoid heat accumulation, good ventilation is required for the
operating environment.
• Keep the camera away from liquid while in use.
• While in delivery, the camera shall be packed in its original packing or
equivalent.
• Regular part replacement: a few parts (e.g., electrolytic capacitor) of
the equipment shall be replaced regularly according to their average
endurance time. The average time varies because of differences
between operating environments and usage history, so regular
checking is recommended for all users. Please contact your dealer for
more details.
• Improper use or replacement of the battery may result in explosion
hazard. Replace with the same or equivalent type only. Dispose of
