Page 5 of 31 VI350-MANUAL-EN.R1.doc

1.3 Precautions

• Use only the power adapter supplied with the system. The use of any other
power adapter may cause damage to the system which is not covered under
warranty.

• Keep it dry. If water should get on it, wipe it off immediately. Water contains
minerals that can corrode electronic circuits.

• Do not use or store in area of high levels of dirt or dust. The electronic circuit
may be contaminated, and any moving parts will wear prematurely.

• Avoid installing the monitor directly into the sun or in any other intensely bright
locations.

• Do not install the monitor in areas where it may be exposed to excessive
moisture or extreme temperatures.

• Do not install near corrosive chemicals or harmful gases.

• Before installing the system completely, it is a good idea to check for proper

operation by temporarily connecting the monitor to the camera and powering
up units.

sound.

NOTE To toggle the additional camera ON/OFF disconnect and reconnect the power

supply while holding the “Speakerphone and Monitor” buttons at the same time
for 1~3 seconds, each time.

4.2 Video Doorphone Operation

Operating the doorphone system consists of responding to visitor calls from the
camera unit, monitoring audio and visuals, speaking to another monitor and
remotely opening the door.

1 Visitor Calls From Camera Unit

Page 16 of 31 VI350-MANUAL-EN.R1.doc

• When the Call button on the camera is pressed, All monitors in the
system will ring the doorbell chime and turn the screen ON.

• After the call, if the “Speak-out” or “Two-way” button is not pressed, it will
cutoff after 30 seconds.

• If the “Speak-out” or “Two-way” button is pressed you have 90 seconds
to communicate before it automatically cuts off, or press the “Cut off”
button to terminate a call at any time.

2 Audio & Video Monitoring

• Press the Monitor button for monitoring a camera manually

• Press button again to switch the monitoring channel (If there is more

than one camera connected)

• Press the “Cut off” button to end the monitoring mode

3 Intercom Function between Monitors

• Press the “Intercom” button from any monitor to generate a call
signal at all monitor locations (i.e. expansion monitor)

• From another monitor respond to a call signal by pressing the “Two way”
button. The calling monitor and responding monitor can then engage in
the voice intercom function. The intercom LED will turn ON at all monitor
locations to indicate the intercom function is engaged.

NOTE Only 2 monitors are allowed in this function.

Now 2 monitors can talk to each other, “hands-free”. This function will

be terminated automatically after 90 sec, or when the “cut off” button is
pressed, or when the calling button on the outdoor camera is pressed.

4 Door Release Function

• Pressing the “Door Open” button at the monitor (which must be
online), will activate the door strike at the online camera. (Door strike
EDS350 sold separately).

• The “Door Open” button at an offline monitor cannot activate this
function.

8.1 Connect Electric Door Strike or Magnetic Lock (optional)

IMPORTANT NOTE

Before attempting to install the Electric Door Strike or
Magnetic Lock please call a professional such as a locksmith
or electrician to help with your installation.

1. N.O. Dry Contact Option

You can open the door remotely by pressing the Door Open button on the monitor to
release an electric door strike or magnetic lock

(1) Connect two wires (18 gauge)
to the Outdoor Camera marked
“Door Release” to the Electric
Door Strike.

(2) One wire from the Outdoor
Camera will connect to the
positive terminal on the power
supply.

(3) The other wire from the
Outdoor Camera will connect to
the positive terminal on the door
strike unit.

(4) A third wire will connect from
the negative terminal on the
power supply to the negative
terminal on the door strike unit.

Page 27 of 31 VI350-MANUAL-EN.R1.doc

IMPORTANT NOTE

You will need to install a power supply that is compatible with
the eletronic door strike installed.

For example: if a 12V DC / 320 mA Electronic Door Strike is
used, then a compatible power supply would be 12V DC / 500
mA (the power supply should have a higher current rating
than the door strike so that it could handle the requirement

CAUTION

Potential for damage to the unit
Do not overload the current on the lock.
Current overload may cause damage on the monitor and

door strike unit

2. 12V DC 300 mA Power Option

Connect two wires (18 gauge) between the camera terminal marked “Door Release”
and the Electronic Door strike, see Figure 12.

Figure 12: 12V DC 300 mA Power Option

NOTE When using the 12V DC 300 mA power option, make sure that the Electric Door

strike used is rated for 12V DC and the current rating less than 300mA.

9.1 Connect the Video Doorphone System with Existing Wiring

Although there are many different styles of doorbell systems on the market, they mainly
consist of the same 3 main components and are installed in the same way.

These are the 3 main components in a typical doorbell system: Doorbell (a visitor at the
door presses it), Transformer (or power –it is attached to the house circuit and provides a
voltage output of approximately 6 to 24 volts) and Doorchime (it rings when the doorbell is
pressed).

Figure 13: Household Wiring for a Typical Doorbell

The following basic instructions explains how to install the Video Doorphone System
using your existing doorbell wiring.

IMPORTANT NOTE

Turn off the breaker that supplies power to the doorbell
before attempting to install the doorphone system. Please
call a professional such as a locksmith or electrician to help
with your installation.

Step 1. Remove the Doorbell Wires from the House Circuit

NOTE Typically Doorbells use "transformers" to convert the current in your house to low voltage current

(i.e. approximately 6 to 24 volts). The transformer is attached to the house circuit and provides
power to the Doorbell.
