Precautions for installation
Before installation
The main monitor station (called 
"
main monitor") and the camera use radio waves to communicate 
with each other. (The product operates in the frequency range of 1.88 GHz to 1.90 GHz, and the 
RF transmission power is 250 mW (max.).) Read the following and install the product in an appro-
priate location.
Operation distance: up to 100 m 
(with no obstacles)
Main monitor
Communication between the main monitor and the camera
Confirming the signal condition at the installation location
 ● The maximum communication distance between the main monitor and the camera (up to 
100 m) may be shortened when the product is used in places where there are the following 
obstacles between the main monitor and the camera.
If there are the above obstacles, images displayed on the main monitor may be distorted 
or delayed, audio may cut out, and the product may not be usable. In this case, the cam-
era’s indicator lamp lights or flashes red. 
(
"Camera signal status" below.
)
If your Video Intercom System includes a sub monitor, it can be used to easily check the sig-
nal status. (If there is no sub monitor, use a camera.)
 ● You can rectify these problems by using an optional DECT Repeater VL-FKD2EX to 
relay the signal from the main monitor. (
 Operating Instructions of the Video Intercom 
System)
By taking the sub monitor to the installa-
tion site, you can confirm the signal status 
on the sub monitor’s screen.
Temporarily connect the camera and the 
power supply unit to turn on the camera, 
and then register it to the main monitor. 
Later, you can take the camera to the 
installation site and confirm the signal sta-
tus using the camera’s indicator lamp. 
■
 
Using the sub monitor to confirm
■
 Using the camera to confirm
 ● In direct sunlight or directly under an 
outdoor light (even if the surrounding 
areas are within the operational 
temperature range, portions of the product 
may become hot)
 ● Areas subject to frequent vibration, shock, 
or impact
 ● Near re, heating devices, or magnetic 
elds (such as near magnets)
 ● Near heating or cooling systems, 
including outdoor equipment such as air 
conditioning unit compressors
 ● In greasy or moist locations
 ● Near devices that emit radio waves, such 
as mobile phones
Do not install in these locations

Incorrect detections may occur in the following locations
 ● Areas where people approach from 
directly in front of the camera, such as 
narrow walkways
 ● In areas where objects move naturally, 
such as where the wind blows trees or 
hanging laundry (temperature variation 
and motion may cause incorrect 
detections)
 ● In areas with strong winds (wind can vibrate the camera, causing incorrect motion detection.)
 ● Where reective objects are in front of the camera and can interfere with the heat 
detection, such as glass.
 ● In areas where brightness changes easily (for example where shadows form in the 
afternoon and where lights turn on at night)
 ● In areas where backlight occurs (faces in the dark may not be able to be identied.)
 ● If a strong light is shining on the camera, the visitor’s face may not be distinguishable.
Do not place the camera in the following locations. 
– Where most of the background is the sky.
– Where the background is a white wall, and direct sunlight will reflect off it.
– Where direct sunlight will shine on the camera.
 ● In areas subject to breezes from fans, air 
conditioning unit compressors, or hot water 
heaters, or areas affected by car exhaust 
(severe temperature variations may cause 
incorrect detections)
 ● On high-trafc streets
(passing cars may cause detections even 
if they are more than 5 m away)
Privacy and rights of portrait
When installing or using the camera, please take into consideration the rights of others with regard 
to privacy.
 ● It is generally said that "privacy" means the ability of an individual or group to stop information 
about themselves from becoming known to people other than those whom they choose to give 
the information. "Rights of portrait" means the right to be safe from having your own image taken 
and used indiscriminately without consent.
The camera has 2 sensors: the motion detection sensor and the heat sensor.
Please read the following information about the camera’s motion detection sensor and heat sensor 
before deciding where to mount the camera.
Sensor characteristics and detection range
Motion detection Motion detection
Motion detection sensor Heat sensor
Detection 
method
The camera detects changes in the 
images being displayed.
 ● The camera detects changes in the 
brightness levels of moving objects.
The camera detects temperature 
differences of objects in the images 
being displayed.
 ● The heat sensor uses infrared rays to 
detect temperature differences within 
its range that are emitted naturally by 
people, animals, etc.
Main  
character-
istics
Easily detects movement in the day-
time or when it is bright.
 ● Movement may be incorrectly 
detected when the moving object 
and the background have a similar 
colour.
 ● Movement may be incorrectly 
detected when there are sudden 
changes to the overall brightness 
levels such as when external lights 
are used.
Easily detects when there is a big dif-
ference between the temperatures of 
objects and the surrounding environ-
ment, such as in winter or late at night.
 ● The sensor cannot easily detect 
when there is no difference between 
the temperatures of objects and the 
surrounding environment, such as in 
summer or during the daytime.
 ● If the camera is mounted facing 
a road, the sensor may detect 
incorrectly due to interference caused 
by the heat from passing cars.

and the heat sensor.
 ● The motion detection sensor and heat sensor are not designed to be used in situations that 
require high reliability. We do not recommend use of the motion detection sensor and heat 
sensor in these situations.
 ● Panasonic takes no responsibility for any injury or damages caused by use of the motion 
detection sensor and heat sensor.
Sensor operating range
In the default settings, the motion detection sensor and heat sensor operate in the following way 
depending on changes to the brightness levels.
Daytime or when it is bright At night or when it is dark
Motion detection sensor
Heat sensor
 ● The brightness level is automatically determined by the camera when viewing images.  
A timer can be congured to switch the modes between day and night modes at specied times. 
(
 [Day and night switch] setting in the Operating Instructions of the Video Intercom System)
 ● The settings can be congured to match the installation environment by only operating the 
motion detection sensor and heat sensor at certain times, for example only during the day 
or only at night. (
