ask the service technician to perform routine safety checks to  
determine that the appliance is in safe operating condition.  
This installation should be made by a qualified service  
person and should conform to all local codes.  
This camera has a built-in AGC circuit. Setting AGC  
to "Mid" or "High" increases the sensitivity of a dark  
image, and the screen may appear grainy. This is not  
a malfunction.  
Locations that may contain steam or oil, such as kitchens.  
This installation shall be in accordance with the National  
Electrical Code, ANSI/NFPA 70. The unit is to be powered  
by a Listed Class 2 power supply or using the PoE.  
The AC 24 V power supply should conform to the following:  
Class 2 only (For USA), Isolated power supply only (For  
Europe and other).  
Any Mention in this manual of Alarm inputs have not been  
evaluated by UL to be used for Burglar Alarm Functionality.  
Special technique is required when installing this product.  
Please refer to your dealer for installation.  
• Locations that are subject to radiation emissions,  
X-rays or corrosive gases.  
• Locations where chemicals are used, such as  
swimming pools.  
Use of this camera and cables connected to this  
camera at locations where strong electrical or  
magnetic waves are generated (e.g. near a radio, TV,  
transformer, monitor, etc.) may result in images being  
affected by noise interference or colors being changed.  
When this camera is used with the white balance set to  
"ATW" (Auto Tracking White Balance), the color tone  
of some objects may differ slightly from the actual color  
due to the principle of the automatic tracking white  
balance circuit. This is not a malfunction.

an equilateral triangle is intended to alert the  
user to the presence of uninsulated "dangerous  
voltage" within the product's enclosure that age"  
within the product's enclosure that may be of  
sufficient magnitude to constitute a risk of electric  
shock to persons.  
The rotation angle of this camera is increased to  
enable installation at a wider variety of locations. When  
the lens is at the wide-angle position, and tilted at an  
angle close to +/-80 degrees, a part of the camera  
may come into view on the screen depending on the  
rotation angle. When this occurs, adjust the field angle  
accordingly.  
Handling Precautions  
Do not block the vents.  
The exclamation point within an equilateral  
triangle is intended to alert the user to  
the presence of important operating and  
maintenance (servicing) instructions in the

cover and secure it using the supplied wrench.  
• Before installing the dome cover, make sure that silica gel (supplied)  
is placed inside.  
• Mount the dome cover firmly. If it is not fixed securely enough, the  
moisture inside the camera increases, fogging the inside of the cover  
or causing the cover to fall off.  
• If you remove the dome cover after installing it, the field angle may  
shift. If the field angle has shifted, adjust the focus and the field  
angle again.  
• Pay attention to the fall prevention wire so that it will not be caught

non-voltage contact signal in the Alarm IN terminal.  
• Do not supply voltage.  
• The alarm can be set to be activated during close  
contact (MAKE) or during open contact (BREAK)  
can be set from the menu.  
• The alarm signal should last for at least 500  
msec. If the alarm signal is short, it may not be  
recognized.  
You can configure the menu to set the alarm to  
sound when contacts short circuit (MAKE) or  
when the contacts are open (BREAK). (Pressure  
resistance lower than 16V, 30 mA)  
• This terminal has different polarities. The output  
voltage at the positive terminal must always be  
higher than the output voltage at the negative  
terminal. Otherwise, the circuit may be damaged.
