COMMUNICATION & SECURITY SOLUTIONS

Add Two-Way Voice Communication

to Your Existing IP Network Camera

Features

It is common for IP based network cameras to have two­way audio connections. When this is the case, the MSB-
30 can be added to turn your IP network camera into a
VoIP (Voice over Internet Protocol) video phone, allowing
both voice and video to stream over the internet. If the
camera already has a tiny speaker and microphone, the
MSB-30 can be added to get better and louder sounding
audio by using the audio input and output connections
provided by the camera. The MSB-30 has a microphone,
a speaker, and a momentary push button housed in a
stainless steel flush mount panel. An optional Viking
model VE-5x5 can be used to surface mount the unit to a
wall or pedestal.

The MSB-30 line level audio input and output connections
can be directly connected to the IP camera’s line level
audio output and input connections for two-way voice
communications. A built-in 2 watt amplifier powers the in­ternal speaker, and there are volume controls to adjust
both the speaker volume and microphone sensitivity. The
2 watt amplifier can be used to power an auxiliary speaker
for even greater volume and coverage.

The MSB-30 also has a momentary “CALL” button switch
which can provide a momentary contact closure to trigger
the IP network camera, or ring a door bell. The front panel
blue LED lights continuously to show the unit is powered,
and to help identify the “CALL” button location at night. An

external contact closure can be used to turn off the blue
LED, or simply wire it in parallel with the momentary “Call”
button switch to make the blue LED wink off when the but­ton is pressed.

The MSB-30-EWP adds Enhanced Weather Protection
(EWP). Use for outdoor installations where the unit is ex­posed to precipitation or condensation. EWP products fea­ture foam rubber gaskets and boots, sealed connections,
gel-filled butt connectors, as well as urethane or thermal
plastic potted circuit boards with internally sealed, field­adjustable trim pots. For more info, see DOD# 859.

IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges from both the AC
outlet and the telephone line. It is recommended that a surge protector be installed to protect against such surges.

A. Mounting

The optional VE-5x5 Surface
Mount Box is designed to be surface mounted
to a single gang box, double gang box or VE-
GNP gooseneck pedestal (right). For more in­formation on the VE-5x5 and VE-GNP see
DOD# 424.

Important: The MSB-30 will NOT
mount to a standard double gang box.

Caution: When warm air comes in contact with cold surfaces, such as outside walls and conduits, it causes con­densation. To prevent condensation from accumulating inside the MSB-30 always bring conduit into the bottom
of the unit. If this is not possible, drill a 1/4” diameter hole in the bottom of the black plastic box.

*Note: Peel off paper liner and adhere gasket to the back of the faceplate, centering it over the four corner mount­ing holes.

Note: The plastic rough-in box (part # 259576) may be purchased
separately in advance. Go to www.vikingelectronics.com and
click on “Spare Parts”.
