Page 7: Initial Preparations
INITIAL PREPARATIONS • The camera voltage regulator board (VRB) accepts an input voltage of either 12V dc or 24V ac, and a range in-between, from a regulated power supply. • The VRB automatically switches between ac or dc inputs, therefore no internal wiring changes are necessary to accommodate these input voltages. -
Page 8: Section 1. Cover Removal
1. COVER REMOVAL The camera’s cover must be removed prior to adjustment for LED brightness or setting the camera’s lens angle. The set-screw located at the bottom of the cover casting is not tightened at the factory and protrudes by 1/8" (3mm) in order for the cover to be easily rotated. - Page 9 Set-Screw Camera Body Base Casting O-Ring Gasket Video Output Cable Power Input Cable FIGURE 1 – 1 Cover Removal Cover Camera and LED Array Assembly...

Page 15: Section 4. Camera/Led Adjustments
4. CAMERA / LED ADJUSTMENTS For optimum picture quality, the EX70 camera lens must be as close as possible to the inside face of the viewing window, without touching. However, the foam ring around the lens of the EX70N should be adjusted to seal against the inside face of the window, minimizing any side light interference, but without obstructing the field of view. - Page 16 Remove the chassis mounting screws and lift out the assembly FIGURE 4 – 1 Camera Removal This illustration shows the EX70N camera. The EX70 is similar, but has no LED Array. Note the relationship between the camera board alignment and the housing.
- Page 17 FIGURE 4 – 2 Camera Lens Adjustment For optimum picture quality, the two adjustment screws, located on either side of the camera plate, allow the lens to be moved closer to the viewing window. The lens directional view can also be slightly adjusted during this procedure. Adjust the lens foam ring at this time.

Page 19: Section 5. Camera Re-Assembly
5. CAMERA RE-ASSEMBLY If changes were necessary due to voltage and installation requirements, make sure all power and video wires are correctly connected and tightened into their terminal blocks. Step 5.1 - Connect a ¾” NPT gland or conduit to the open side of the base: Note: The gland and conduit is not supplied. - Page 20 Step 5.5 - Mount this Chassis into the Base Housing, ensuring no cables are pinched or chafed. Step 5.6 - Thread the Cover onto the Base, making sure the Lens and its Foam Ring are correctly positioned. Thread the ring on tight and then tighten the set-screw on the cover.

Check the video signal. If okay, the problem is with the interconnections. If still no video, contact Bosch Security Systems (see back cover for contact details). _________________ Ensure video cable is correctly matched and terminated with 75 ohms at each end. - Page 25 Poor Picture Quality Snowy Image (cont’d.)
