3Installation Overview
CAUTION!
Installation should be made by qualified service personnel and conform to the National
Electrical Code and applicable local codes.
The MIC Series cameras are designed for easy installation on a variety of common fittings. The
most common type of mount used is a dedicated CCTV camera pole where the camera is
bolted directly to the top using industry-standard 4 in. (101.6 mm) fitting. This type of camera
pole provides a robust mounting platform that minimizes camera motion and typically has a
large base cabinet for mounting ancillary equipment such as power supplies.
The camera can also be mounted on lamp post columns using the Pole Mount Bracket (MICPMB); however, users should be aware that lamp posts can often be subject to movement and
are not suitable platforms in all conditions or for all applications.
For mounting directly onto buildings, Bosch Security Systems manufactures a range of
brackets suitable for all typical building installations for upright (90°) or Inverted positions.
Figure 3.1 MIC camera mounting positions: Inverted, and Upright (Graphic is not of MIC612)
The camera’s adaptability enables easy integration in a wide variety of mobile and redeployable installations. These have included lifeboats and other surface/subsurface vessels,
emergency service vehicles, highway agency vehicles, council/contractor parking enforcement
vehicles, and crowd-control vehicles.
Below are examples of typical mounting arrangements for MIC Series cameras.

3.2Mounting Positions
CAUTION!
The upright unit can be mounted either with the camera ball up or down. To get the picture
the correct way for installation with the camera ball down, rotate the camera tilt axis 180°.
If the camera is mounted ball down, it is essential that the connector and base area of the
camera are completely sealed from water ingress. Any water getting into the connector is
liable to cause corrosion to the connector pins, leading to unreliable operation of the camera
unit. To prevent water penetrating the composite cable connector threads, seal the 25 mm
thread at final installation using PTFE tape. Alternately, a suitable sealant may be liberally
applied to the thread prior to final tightening.
MIC Series 612 cameras are designed to be mounted upright (straight up, 90°) or inverted
(straight down, 90°). See the figure below for the correct ways to mount the camera.
MIC shielded composite cables are 2-conductor cables of various lengths (and gauges ranging
from 14 - 18) that provide all power, video, and telemetry connections between the MIC PSU
and the MIC camera. The cables are pre-made with a female-terminated 14-pin connector at
one end for attachment to the male connector installed into the base of the camera. The other
end of the cables has free (non-terminated) wires for wiring into terminals in the MIC PSU.

4.2Mounting the Camera
CAUTION!
Fasteners are not supplied with MIC612 cameras because the type of fastener used depends
on the material to which the fastener is attached. The material must accommodate a minimum
pull-out strength of 275 kg (600 lbs.) Fasteners can include wedge anchors, sleeve anchors,
single expansion anchors, double expansion anchors, machine screw anchors, or "ThruBolting" with a nut. All fasteners must be made of 303(A2) stainless steel, at a minimum, with
a diameter of 8 mm (5/16-in).All bolts must fully extend through the mounting surface and be
secured with a flat washer, lock washer, and a nut. All studs must be anchored to concrete or
welded to a steel backing plate. Anchor bolts can be used for blind structures where there is
no access to the rear.
To mount a MIC Series camera, follow these steps:
1.Identify a secure location for the mount and for the camera. Locate the mounting position
so that the camera cannot be interfered with intentionally or accidentally. Ensure that the
installation location has the appropriate clearance from power and lightning conductors,
in accordance with NEC725 and NEC800 (CEC Rule 16-224 and CEC Section 60). Do not
install the camera near:
–Any heat sources
–Any overhead power lines, power circuits, or electrical lights, or where it may
2.Ensure that the mounting surface is capable of supporting the combined weight of the
camera and mounting hardware under all expected conditions of load, vibration, and
temperature. MIC612 cameras must be secured to one of the following surfaces:
–Concrete Solid/Cast
–Concrete Masonry Unit (Concrete Block)
–Brick (all types)
–Metal (Steel/Aluminum, minimum 1/8-in. thick)
Note: If the camera is positioned in a highly exposed area where lightning strikes may
occur, it is recommended to install a lightning conductor within 0.5 m of the camera and
at least 1.5 m higher than the camera. The construction of the housing itself is capable of
coping with secondary strikes. If the correct lightning protection is applied, no damage to
the internal electronics or camera should result. An earth bonding connection to the case
also provides protection against damage from secondary strikes. (See step 8.)
3.Fit the mounting brackets securely, observing all appropriate safety precautions and local
building regulations.
4.Carefully lift the camera to the mounting point.
5.Attach the security attachment point to a safety chain (not supplied).
6.Attach the safety chain to a secure part of your mounting structure.
7.Connect the female 14-pin connector end of the shielded composite cable to the male
plug in the base of the camera. Screw the cable connector sleeve onto the plug until it is
firmly secured (approximately four (4) turns from the start of thread engagement).
8.Earth the camera using one of the securing supplied bolts. Only earth the camera at a
single point to prevent earth loops and video distortion (hum bars), caused by electrical
interference, from appearing on the camera picture in the control room. Please note the
following:
–The camera module and housing are electrically isolated, so the housing should be
safety earthed regardless. The safety earth should be a bonding connection (for
example, one of the securing bolts) to the camera’s outside case, and should be
attached to the Earth terminal post on the PCD base of the camera.
–If the system is copper throughout and the camera pictures are fed back to the
control room via coaxial copper cable, then the camera should be earthed only at the
video termination point in the control room. In this case, the "Earth Link" on the PCB
should be broken. Refer to
–If the video is transmitted back to the control room via some non-electrical
connecting medium (for example, fiber optic, radio, or microwave link), then the
camera should be earthed at the transmitter point in the power supply unit. The PSU
"Earth Link" may be used for this purpose.
–If dual earthing is unavoidable, then a video isolation transformer should be fitted
between the two earths.
9.Use M8 x 20 mm stainless steel nuts, bolts, and washers to secure the PCD base of the
camera to the mounting bracket. An additional Nebar gasket or suitable silicone sealant
can be used to ensure a water tight seal between the base and mounting surface. Tighten
all bolts securely.
10. Secure all cabling and conduit.
WARNING!
If the camera is mounted ball down, it is essential that the connector and base area of the
camera are completely sealed from water ingress. Any water getting into the connector is
liable to cause corrosion to the connector pins, leading to unreliable operation of the camera
unit.

WARNING!
To prevent water from penetrating the composite cable connector threads, the 25 mm thread
should be sealed at final installation using PTFE tape (not supplied). Alternatively, a suitable
sealant may be liberally applied to the thread prior to final tightening.
4.3Installing the MIC Power Supply Unit (PSU)
Each MIC power supply unit (PSU) provides all of the connections needed for power, video,
and telemetry for a single MIC camera. Each MIC PSU has CE and FCC approval and has a
cast-aluminum enclosure that is weather-resistant (rated IP65). Features include:
–A provision for driving various optional interface cards mounted internally to the MIC
power supply enclosure (for example, an 8-input alarm card (MIC-ALM))
–A provision for a signal interface card (MIC-BP4) to connect telemetry to Bosch Biphase
equipment
–Screw termination of all cables (composite, telemetry, and ancillary) into and out of the
enclosure
–Earth isolation and termination within the unit to control video earthing correctly and
thus prevent earth loops
Each MIC PSU ships with the following parts:
–Three (3) M12 cable glands for telemetry, video and ancillary equipment
–One (1) M16 gland for connection of the shielded composite cable to the MIC camera
–One (1) 1/2 in. NPT cable gland for the power cable connection
–One (1) 1/2 in. NPT and one (1) M12 blanking plug
MIC612 cameras can use the MIC-240PSU-2 power supply (a 230 VAC source) or the MIC115PSU-2 power supply (a 115 VAC source). The dimensions (H x W x D) of the enclosures
are: 90 x 260 x 160 mm (3.54 x 10.24 x 6.3 in.). The weight is 3.2 kg (7.1 lb).
4.3.1Earth Link on PCB
The printed circuit board (PCB) has one Earth Link option, near terminal block HD1, to allow
the PSU to be set up for different earthing schemes:
–If there is a separate connection between video screen and earth, the Earth Link should
be broken. This usually occurs on copper-connected systems where all of the copper
video coaxes are taken back to the control room to be connected to a central earth point.
–If fiber optics or other indirect connections are used to get data and video to and from
the control room, then the Earth Link should be left intact, as long as it is the only
camera-end earth reference point.
4.3.2Fuse Ratings
The MIC PSUs for MIC612 cameras have four (4) off 20 mm fuses (numbers 13 - 16 in
Figure 4.1) in fuse holders. The ratings for these fuses are fixed on the low voltage secondary
side but change with input voltage on the high voltage primary side. The following table shows
the fuse values that should be fitted to provide proper protection for the MIC-240PSU-2 and
MIC-115PSU-2 power supplies. Note: FS 4 does not exist.

4.3.4Installation Instructions
DANGER!
–ELECTRICAL SHOCK HAZARD
To reduce the risk of electrical shock, disconnect power before opening or working on
any power supply unit. Power must be disconnected before replacing any fuse in the MIC
PSU. Power supply units have power supplied whenever the power cord is inserted into
the power source.
–MIC PSUs have a separate internal shield covering the power cable input terminal block
(HD1). Only suitably qualified persons should remove this shield and connect the mains
power cable. The shield MUST be re-installed and fully secured before connecting the
power.
–The power supply cable shall have conductors of a maximum size of 12 AWG.
–Branch circuit protection incorporating a 15 A, 2-pole, listed circuit breaker or branch
rated fuses are required. A readily accessible 2-pole disconnect device with a contact
separation of at least 3mm must be incorporated externally to the equipment.
WARNING!
To meet UL standards and ratings, all external wires for installation applications must be
routed through a permanently earthed metal conduit.
CAUTION!
Except for the Earth Link, heater links, and applicable fuses, the MIC PSUs have no useradjustable parts. MIC cameras have no user-serviceable parts.
CAUTION!
Bosch recommends using an uninterruptible power supply (UPS) in connection with a MIC
camera/PSU installation.
CAUTION!
MIC PSU enclosures are not EXD rated and must be replaced with a certified enclosure if
installed within a hazardous area.
NOTICE!
To maintain the IP rating of the power supply enclosure, install only listed or recognized
conduit hubs or fittings with the same environmental rating as the enclosure in compliance
with the installation instruction of the hub or fitting.
NOTICE!
Refer to the MIC Series Power Supply Installation Manual included with the PSU for full details
on installing a MIC Series PSU and connecting to a MIC612 Camera.
1.Select the mounting position of the MIC PSU so that it cannot be interfered with either
intentionally or accidentally. Bosch recommends using a lockable cabinet.
2.Locate the four (4) mounting holes of the power supply enclosure. (Figure 4.2 displays
one of the holes.) See the dimensional drawing in the appendix for hole locations. The
dimensions shown are for the mounting holes only. The other 4 holes shown are for
securing the lid and are for reference only.
3.Drill four (4) holes in the mounting surface for the mounting anchors appropriate for M6
screws (not supplied).
4.Loosen the four (4) captive Phillips head screws on the top of the lid of the power supply
enclosure (item 2, Figure 4.2). Lift the lid and set it upside down next to the enclosure.
NOTICE!
Do not stretch or cut, or otherwise disturb, the earth core cable (shown in the figure below)
to the inside of the lid and to the earth termination post.

Number Description
1Hole for mounting screw in enclosure
2Hole for lid screw in enclosure
5.Secure the enclosure to the mounting surface using four (4) M6 stainless steel screws
and washers (not supplied), which fit through the large holes in the enclosure, as shown
in Figure 4.2.
NOTICE!
If you are securing the power supply enclosure in a vertical position (for example, on a wall),
one person should hold the enclosure lid while another secures the enclosure body in place,
to avoid damage to any part of the enclosure, and/or injury to the installer(s).
6.Unscrew the four (4) M3 screws on the internal high voltage input head-end shield
(marked with "Danger") covering the mains cable terminal HD1; retain the screws.

7.Remove the internal shield and set it nearby, outside of the PSU enclosure. You can now
access the hole for the power cable and the M20 blanking plug covering the hole.
8.Remove the blanking plug. Install suitable (metal) conduit in place of the blanking plug.
Secure the conduit as recommended by the conduit manufacturer.
CAUTION!
Only installations with conduit meet UL standards. If you choose to use a power cord without
conduit (not recommended), fit the 1/2 in. NPT cable gland (supplied) in place of the blanking
plug. Note: It is easier to fit the power cord through the cable gland outside of the enclosure,
and then attach the gland to the enclosure. Ensure that the cable glands have sufficient room
to allow for the cables to enter (approximately 60 mm on either side of the enclosure).
9.Prepare the power cable as need, then feed the cable into the enclosure.
10. Connect the Live and Neutral cores to the correct screw terminals on terminal block HD1
as identified in the table below and printed on the PCB. Observe polarity and voltage.

11. Remove the brass nut and copper washer from the earth termination post (item 3,
Figure 4.4); set these aside.
12. Remove the ring terminal (supplied).
13. Insert the earth core from the mains cord (item 2, Figure 4.4) into the crimp portion (size
M6, UL-certified) of the ring terminal and crimp it in place.
14. Place the ring terminal onto the earth termination post.
15. Replace the copper washer. Secure with the brass nut.

16. Replace the internal shield, taking care to avoid pinching the cables. Tighten the screws.
17. Feed the unconnected end of the shielded composite cable through the top-right M16
cable gland (item 2, Figure 4.5).
