DESCRIPTION The EX36N Night Vision Camera has been designed with tilt on its faceplate to allow corner mounting and provide better view angle in small rooms. The housing and faceplate consist of tough materials to withstand damage in hostile environments such as prison cells and psychiatric wards. The smooth compact housing allows for tight installations without exposed wiring or mounting screws, while separate windows for the camera lens and LEDs result in a perfect picture without light rebound.
UNPACKING 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.
INITIAL PREPARATIONS Determine the operating voltage at the installation site. Determine the optimum location for the camera. Section 3, Mounting-Camera Housing. All cameras have been tested prior to shipment. After the wiring has been reconnected, it is advisable to check the camera’s operation before installation. GUIDELINES The installation of the EX36N camera is explained in Sections 1 to 6 listed below. It is important that these steps are followed in sequence: 1. 2. 3. 4. 5. 6.
1. FACEPLATE REMOVAL The faceplate must be removed prior to the installation process. This is necessary because the mounting holes need to be accessed. The lens may need to have its directional angle changed. Refer to Figure 1-1 on page 5. Step 1.1 - Place the camera housing on a flat surface. Step 1.2 - Use the supplied “security” Allen wrench to remove the six screws holding the faceplate into the housing. Step 1.3 - Remove the square foam cushion attached to the camera lens. Step 1.

This view shows the interior layout of the EX3xN camera assembly after the faceplate has been removed. Smaller details such as wiring and terminal blocks are omitted for clarity. Refer to the specific module sections for these details.
2. INPUT POWER CONNECTIONS The camera unit is pre-connected with an electrically isolated power board for 24V ac or 12V dc operation with no wiring change or wiring polarity. See Figure 2-1 and 2-2 for wiring details.

3. MOUNTING - CAMERA HOUSING 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. See page 24 Caution: Ensure the selected location is protected from falling objects, accidental contact with moving objects, and unintentional interference from personnel.
• • expected conditions of vibration and temperature. Secure all cabling. Installations on drywall must use #8 screws and #8 drywall nylon plugs or a superior connection. The camera’s mounting holes are located on the left and right side of the housing. Refer to Figure 3-1 on page 11. Depending on the type of mounting surface (brick, wood, etc.), it may be necessary to predrill these holes for the mounting screws.

4. CAMERA - DIRECTIONAL ADJUSTMENT Both the camera and the LED array can be adjusted for optimum picture quality. The camera lens can be tilted on its axis via two adjustment screws on the mounting bracket. It can also be moved closer or farther away from the viewing window. Mount the Camera/LED Array Assembly into the housing. Connect the video and power wires. Check the picture for quality and directional alignment.
Loosen both adjustment screws for tilt or horizontal directional alignment. This action may require trial-and-error attempts to obtain perfect picture alignment.
5. LED DIRECTIONAL AND POWER ADJUSTMENTS If the LEDs need to be adjusted for beam spread, the Camera/LED Array Assembly does not need to be removed from the housing. The adjustment can be done by hand. The EX3xN can be powered while making adjustments, but make sure the power cable is not pinched or chafed during this procedure. Cover or adjust the photo-cell to turn the LEDs “ON” (850nm LEDs will have a slight red glow while 940nm LEDs are covert). Adjust the LED power if they are too bright.
LED ARRAY - POWER ADJUSTMENTS If adjustment is needed, remove the rear cover for access to the LRB. The EX36N needs to be powered-up while making the LED power adjustments. Cover the photocell to turn the LEDs “ON” (850nm LEDs will have a slight red glow). For photocell “On/Off” light-level adjustment, rotate VR2. Clockwise is off and counter-clockwise is on. LED Power Adjustment Photocell On/Off Adjustment LED Power and Photocell On/Off Adjustments Adjust the LED power if they are too bright or too dim.
6. CAMERA RE-ASSEMBLY Make sure all wires are properly connected, all holes are sealed against moisture penetration, and all mounting screws are tight. Step 6.1 - Slide the square foam pad over the camera’s lens. Make sure the pad is as close to the faceplate viewing window as possible and the photocell is not covered by the foam pad. The foam pad is not symmetrical. Make sure the LEDs are not covered when installing the pad. Step 6.2 - Re-attach the faceplate with the six tamper resistant screws.
photocell The foam pad is not symmetrical. Make sure the LED is not covered when installing the foam pad.
7. TROUBLESHOOTING - CAMERA PROBLEM No Video POSSIBLE CAUSE 1. Power Supply: Connections…. LIKELY SOLUTION Check input power connections at the terminal: * AC input wires to “ ac IN”. * DC input wires to “ dc IN”. * Loose wires. The supply range is: 12 – 28V ac OR 10.5 – 40V dc for the camera section. Measure the voltage at the terminal block. -Voltage Range... 2. Video Connections: 18 Determine if wiring polarity at “Video Connector” terminal block is correct.
No Video (cont’d.) 2. Video Connections: (cont’d.) __________ Poor Picture Quality Snowy Image 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 of this manual for contact information. _________________ Poor Video Signal Noisy Power Supply 19 Ensure video cable is correctly matched and terminated with 75 ohms at each end.
Horizontal Scan Lines, Rolling Up or Down. Reversed video or faded image Ground Looping on video cable Low voltage 20 Check the coax cable shield is not touching ground, e.g. at couplings. Check voltage at input power cable. Must be >10.5V dc or >12Vac for camera section. Check video leads for reversed connections.
8. TROUBLESHOOTING - LEDs PROBLEM POSSIBLE SOLUTION Fuse Blows - Check fuse rating. - Check for shorting between the enclosure and the input power. Don’t know if LEDS are “ON” 850nm LEDs will have a faint red glow when “ON”. 940nm LEDs are covert. Aim the LEDs directly at an IR sensitive camera to see the lights or wait for the LEDs to warm up (two minutes). LEDs are not “ON” - Cover the photo sensor to activate power to the LEDs ( up to 30 seconds delay for activation ).
PROBLEM POSSIBLE SOLUTION LEDs are not turning “OFF” when sufficient ambient light is present - Make sure the photo sensor is not covered or hidden behind any object. - Adjust the photocell’s variable resistor towards the “OFF” position. The LEDS will stay “ON” or “OFF” if the adjustments are at full turn.
