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. 
3.3 I/O   
1. I/O   
I/O ports have two I/O inputs and two I/O outputs
