NOTE: This equipment has been tested and found to comply with the limits for a digital device, pursuant to part

15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. As part of its’ normal operation this device can generate radio frequency energy and if not installed and used in accordance with the installation manual may cause interference to radio communications.

However, there is no guarantee that interference will not occur on a particular installation. If the device does cause interference to radio or television reception the user is encouraged to try to correct the interference by one or more of the following measures:

1) Fit Ferrite beads on all cable to and from the power supply box, within the box walls.

2) Route the composite cable between the camera and the power supply in steel conduit piping over the entire run of the cable up to and including connection to a deep conduit base fitted under the camera and a conduit fitting adaptor in the wall of the PSU box.

3) Contact BOSCH Service Center for further advice.

The EX7/8 Ceiling or Wall Mount Camera features one or two CCD sensors to view “coming and going” images.

This is ideal for use in prison corridors, school hallways and underground parking garages. The camera is extremely durable due to its welded metal housing shape and polycarbonate viewing windows. The EX7/8 is also weatherproof, making it perfect for outdoor use.

Cameras are available in monochrome & color.

Voltage regulator circuits automatically allow 12V dc or

24V ac operation without any wiring changes. Its’ wider voltage range also provides protection from voltage surge, transient spikes, and reverse voltage.

The difference between the EX7 and the EX8 is the EX7

Camera is a single sensor version and the EX8 is a dual sensors version.

Care should be taken when unpacking the shipped unit.

Check the parts list and confirm all items have been located.

Inspect the equipment thoroughly to ensure nothing was damaged in transit.

Contact BOSCH Service Center if a problem is noted, see the rear page of this booklet for contact numbers.

 Small slotted screwdriver.

 Hardware for camera mounting (bolts, etc.)

Determine the operating voltage at the installation site. The camera‘s Voltage Regulator Board accepts both 12VDC and 24VAC input without change to internal connections.

Determine the optimum location for the camera.

Section 3, Mounting-Camera Housing.

The factory default is set for ceiling mount. For unique designation wall mount, see section 4.

All cameras have been tested prior to shipment.

The factory default is set for ceiling mount. After the wiring has been reconnected, it is advisable to check the camera’s operation before installation.


Four requirements must be met before the

EX7/8 can

be installed. The sections listed below will aid the installer in setting up the camera for these requirements.

Step 1.1 - Remove the four security screws holding the welded housing to the chassis assembly. Use the supplied Allen key.

Step 1.2 - Carefully separate the housing from the chassis assembly, ensuring the wires are not displaced and the camera lens is not damaged.

The camera unit is pre-connected with an electrically isolated power boards for 24VAC or 12VDC operation with no wiring change or wiring polarity.

See Figure 2-1

for wiring details.


Input voltage is 10.5VDC to 40VDC for DC input.

The AC input range is 12VAC to 28VAC.

NOTE: Section 3 explains the camera’s mounting procedure. It would be advantageous to the installer if the power and video wires from their remote source could be routed into the electrical box at this time. This would make the connections to the camera easier during the mounting process.

Caution: Ensure the selected location is protected from falling objects, accidental contact with moving objects, and unintentional interference from personnel. Follow all applicable building codes.

The following installation guidelines must be followed:

• Locate the camera such that it cannot be easily interfered with, either intentionally or accidentally.

• Select a mounting surface capable of supporting the combined weight of the camera and mounting hardware under all expected conditions of vibration and temperature. Installations on drywall must use #8 screws and #8 drywall nylon plugs or a superior connection.

• Secure all cabling.

The mounting holes are configured for a single-gang electrical box or a ceiling electrical box. See Section 7 for the mounting template.

Step 3.1 Feed the camera’s power & video cables through the foam gasket at the bottom of the camera chassis.

Step 3.2 Connect these cables to the power & video cables that have been routed from their remote location into the electrical box.

Step 3.3 Mount the camera housing to the electrical box and ceiling as shown in Figure 3-1 below.

For optimum picture quality, the lens should be as close as possible to the inside face of the viewing window, without touching.

For unique designation wall mount, rotate the camera to desire location.

Power should be applied when performing the following adjustments.

4.1 Lens Clearance and Tilt Adjustments

Step 4.1.1 - Loosen the screws which secure the camera’s

“slide and tilt” bracket.

Step 4.1.2 - Slide the bracket to its new location, tilt the lens and re-tighten the screws. See Figures 4-1 .

Rotate for unique designation

4.2 Vari Focal and “Auto-Iris” Control Adjustments

Step 4.2.1 - Loosen the lens set screws for focus/zoom adjustments. See Figure 4-2

Step 4.2.2 - The set screw marked

N ←→ ∞ is used for

image focus.

Step 4.2.3 - The set screw marked

T←→ W is used for

telephoto or wide-angle settings.

Step 4.2.4 - Re-tighten the set screws after focus adjustments have been completed.

Step 4.2.5 - Locate the “Auto-Iris” adjustment controls as shown in Figure 4-3 and adjust as per Table

Use a Neutral Density filter or Infra-Red Pass filter to cover the lens during focusing to simulate low light conditions on scene for correct 24-hour focusing. For camera with varifocal lens, the camera should be focused with the lens iris fully opened to simulate the worst possible depth of field.

Using a Neutral Density filter or Infra-Red Pass filter will ensure the iris is fully open for correct setup and adjustment.

Note that statement above is applicable only for Day/Night or

IR version cameras.

Make sure all wires are properly connected and tightened into the terminal blocks, all holes are sealed against moisture penetration, and all mounting screws are tight.

Step 5.1 - Gently press the camera housing in place. Ensure the lens is not touching the inside of the viewing window.

Step 5.2 - Tighten the housing in place with the four security screws and the supplied Allen key.

Step 5.3 - Wipe the viewing window with a soft cloth to remove any smudges or dirt.

Step 5.4 - Check the camera for proper operation.

Check the input power connections at the terminal block, ensuring no wires are loose.

The supply range is:

12 – 28VAC OR

10.5 – 40VDC.

Measure the voltage at the terminal block.

Determine if the wiring polarity at the “Video Connector” terminal block is correct.

Check BNC connector.

If still no video, connect the camera directly to the monitor.

Check the video signal. If okay, the problem is with the interconnections.

If still no video, contact BOSCH

Service Center. See rear page

Ensure the video cable is correctly matched and terminated with 75 ohms at each end.

Make sure the video cables are of similar types.

Check all power connections.

Relocate or replace the power supply.

Check the coax cable shield is not touching “ground”, e.g. at the couplings.

An electrically isolated circuit board or isolation transformer may be required.

Check voltage at input power cable.
