Installation Instructions

1. Locate the network drop that is ran back to the POE switch. (If the switch does not have POE, you will need to insert a POE injector back at the network closet).
2. Remove the P3374/P3375 camera from its base with the starbit security driver. Using a stud finder, ensure there aren’t any studs any behind the camera base. Using a marker or pen, mark the 2 areas on the wall where the screws would be and also mark the opening where the any cabling would come through
3. Using the drill bit, drill the 2 screw markers and place the anchors inside. Using the hole saw (recommended size 2” inches or less), drill a hole into the area where cables would come through.
4. Above drop ceiling, locate the network drop. IF it is on a biscuit, you will need the patch cable. If there is an RJ-45 at the end of the drop, the patch cable won’t be needed. Using the hole saw, drill a hole above the drop ceiling in line with the hole drilled where the camera will be mounted. If there isn’t any drywall above the ceiling, adjust accordingly to your circumstance.
5. Using your glow rod or fish tape, fish the network drop and a section of 22/2 audio cable up the drywall. The section of audio cable should be long enough to reach the destination where the Shure MX202i microphone will be mounted in your drop ceiling. This cable will be for your microphone. (If using 2 microphones, run 2 cables).
6. Mount the Axis P3374/3375 base to the wall using the screws associated with the anchors.Run your network drop and audio cable through the hole on the wall.

1. Cut 2 additional pieces of 22/2 cable approximately 4 inches long. Strip the jacket off the 22/2, revealing the red, black, and common (bare wire) on both sides of the cable. Remove the string and plastic casings covering the red and black cables. Strip the red and black jackets off the wire exposing the copper. Cut copper evenly on both ends (See picture). On the two 4 inch cables, remove the common (bare wire) completely.

   

2. You will also need to cut another shorter piece of 22/2 cable (approx. 1 inch). Strip the jacked and from the cable and remove all contents keeping only the red cable. On both ends of the red cable, strip off a piece of the jacked (See picture).

   

Connecting the STM-

1. Connect one end of the 1 inch audio cable to the +PWR terminal and connect the other end of that into the +PHNTM terminal.

   

2. Connect one of the 4 inch cables to both PWR terminals (Red to +, Black to the other terminal) of the STM-1. Connect the other side to the IO phoenix connector (Red to 2, Black to 1).

   

3. Connect the second of the 4 inch cables to both HI-Z OUTPUT terminals (Red to +, Black to the other terminal) of the STM-1. Connect the other side to spliced 3.5mm audio cable.
4. Connect the audio cable that is intended for your microphone to the input terminals of the STM-1 (Red to +, Black to -, Common to the common terminal). Using the Velcro that comes with the STM-1, attach the STM-1 to the wall above drop ceiling hidden from sight..

(NOTE; If there are 2 cameras in the room, duplitcate step 9.1.3 using a long enough cable to get to the 2nd camera. If there are 2 Shure MX202i Microphones, duplicate step 9.1.4.)

Connecting and Mounting the Microphone

1. Strip the jacket of the XLR pigtail revealing the red, black and common cables inside. Strip away a portion of the red and black cables inside the pigtail, revealing the copper wire inside. At the end of your 22/2 cable (not connected to the STM-1), twist the wires together with the pigtail (red to red, black to black, common to common). Secure these with B-Connectors (See Pictures). Repeat this process for 2 microphones.

   

2. Using the ½”paddle bit, drill a hole into the center of the single gang plate and a hole into the desired location for the microphone on your drop ceiling tile. Then secure this single gang plate to the desired location of the microphone on your drop ceiling tile using a pair of toggle bolts. Repeat this process for 2 microphones.

   

3. Run your MX202i through the ½” hole in the ceiling tile and single gang plate. Connect the 4 Pin XLR-F end of the MX202i to the 4 pin XLR-M adapter. Next, connect the XLR-F (that is ran back to the STM-1) to the XLR-M of the adapter. Lastly, use the rubber stopper to plug the ½” hole in the single gang plate.
4. Lastly, adjust the length of the cable of the microphone to your desired length, hiding the remainder in the ceiling. Attach the windscreen to the MX202i.
