3.1 Maintenance

To keep the Network Camera in the good condition, maintenance plays an
important part. Please keep maintenance when using the Network Camera.
Network Camera
• Network Camera is intended for indoor use only. Prolonged exposure to direct
sunlight or halogen light may damage the CMOS sensor.
The Fixed Focused lens
• Do not touch the movable lens part around the Fixed Focus Lens even in the power
off state. If you touch the movable lens part in the front of the Network Camera, it
may damage the Network Camera.
• Do not touch the Fixed Focus Lens. It may leave a fingerprint and can cause the
image to be out of focus. This can also take away the protective coating on the Fixed
Focus Lens.
• Clean the lens with a Lens Cleaning paper.

3.2 Interfacing to the I/O Connector

The Alarm mode in the Image Transfer feature requires the external sensors/devices to
be connected to the digital input terminal of the I/O Connector. The sensor is customer
provided and can be a door sensor or infrared ray intruder sensor. In most applications
a simple contact closure is all that is required.
