1. DESCRIPTION The EX27 camera is an all-weather system that includes all of the best features of a “plug and play” camera without compromise to CCD optics and lens quality. Full size vari-focal auto-iris lenses are integrated as standard equipment for simplified installations. High resolution extended day/night CCDs ensure that a picture is received under extreme outdoor lighting conditions.
2. UNPACKING Care should be taken when unpacking. Check the parts list and confirm all items have been located. Inspect the equipment thoroughly to ensure nothing was damaged in transit. Contact a Bosch Service Center if a problem is noted, see the rear page of this booklet for contact numbers.

5. INITIAL PREPARATIONS Determine the operating voltage at the installation site. All cameras have been tested prior to shipment. Select a suitable location that is protected from accidental damage, tampering, and environmental conditions exceeding the camera’s specifications. Caution: The selected mounting location should not place the camera in a situation where its environmental specifications could be exceeded.
6. GUIDELINES 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. Secure all cabling. Installations on drywall must use a ¼” bolt and drywall butterfly type anchor or superior connection.
7. VOLTAGE INPUT The camera unit is pre-connected with an electrically isolated power board for 24VAC or 12VDC operation with no wiring change or wiring polarity. See figure 7-1 for wiring details. Note: Input voltage is 10.5VDC to 40VDC for DC input. The AC input range is 12VAC to 28VAC.
8. CAMERA AND LENS ACCESS The following steps show the installer how to access the camera board and the camera lens. Step 2.1 - Remove the four cap screws with a 3mm Allen key. See Figure 8-1 on page 15. Step 2.2 - Carefully slide out the rear housing from the main enclosure. Make sure the gasket remains with the rear section. See Figure 8-2 on page 16. Step 2.3 - Make any necessary camera or lens adjustments as described in Section 9, 10 or 11. Step 2.

9. PHOTOCELL ADJUSTMENTS The photocell settings are optimally set from the factory; only adjust these settings if experiencing undesired day/night switching operation. To increase the night switching sensitivity turn the dial clockwise, to increase the day switching sensitivity turn the dial counter-clockwise. For EX27N versions refer to figure 9-1. For EX27 and EX27D refer to figure 9-2.
Photocell Adjustment FIGURE 9 – 2 EX27/EX27D Day/Night Switch Adjustment 18
10. LENS ADJUSTMENTS Refer to figure 10-1 and follow the directions below: Loosen the lens set screws for focus/zoom adjustments. The adjustment marked T ←→ W is for image zoom. The adjustment marked N ←→ ∞ is for image focus. Re-tighten the setscrews after focus adjustments have been completed.
Use a Neutral Density filter or an Infra-Red Pass filter to cover the lens during focusing to simulate low light conditions on scene for correct 24-hour focusing. For varifocal lenses, 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.
11. OSD MENU SYSTEM 1. Follow the instructions in Section 8 to access the OSD controls. 2. Enter the OSD menu by pressing the joystick button; to navigate through the menu use up, down, left and right. 3. Follow the instructions below to make camera adjustments.
12. TROUBLESHOOTING GUIDE PROBLEM No Video POSSIBLE CAUSE 1. Power Supply: -Connections…. -Voltage Range... LIKELY SOLUTION Check input power connections at the cable leads. Check for loose wires. If connected to DC, check voltage input range of 10.5 - 40 V. If connected to AC, check input voltage range of 12 – 28 V. Measure the voltage at the Input terminal block.
No Video (cont’d.) 2. Video Connections Determine if wiring polarity at “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 a Bosch Service Center. See rear page of this manual for contact information.
Poor Picture Quality Snowy Image (cont’d.) Noisy Power Supply Check connections. Relocate or replace power supply. Horizontal Scan Lines, Rolling Up or Down Ground Looping on video cable Check the coax cable shield is not touching ground, e.g. at couplings. An electrically isolated circuit board or isolation transformer may be required. 24V ac operation Line Lock adjustment required. Low voltage Check voltage at input power cable. Must be >10.5V dc or >12V ac.
13. GENERAL SPECIFICATIONS Input Voltage: 10.5-40 VDC 12-28 VAC (50/60Hz), 4.5W Enclosure (housing): Aluminum casting and extrusion (sealed to IP66 / NEMA4) Viewing Window: Polycarbonate Weight: 1.4kg ( 3.1lbs. ) Subject to Change Without Notice.
