Installation Instructions

Disassemble the Camera

1. Locate the network drop above the ceiling. It should be terminated with a male Ethernet end (service loop) or a biscuit jack. This line will have been ran back to the POE switch.

   Note: If the switch does not have POE, a POE injector will need to be installed at the network closet.

2. Using the T20 bit, remove the dome from the P3374/P3375 camera with the T20 security bit.

Drywall Mounting Instructions

1. Using a stud finder, ensure there aren’t any studs where the camera base will be installed.
2. Using a pencil, trace the 2 anchor points on the wall where the screws will be installed and mark the opening where the any cabling will pass through.
3. Using a 3/16” drill bit, drill 2 holes at the traced location and insert the plastic anchors.
4. Using the hole saw (recommended size 2”), drill a hole into the area where cables will pass through.
   • Ensure the cut hole does not extend past what the camera dome will cover.
5. Using the hole saw, drill a hole above the drop ceiling in line with the hole drilled where the camera is mounted.
   • If there is no drywall above the ceiling, adjust accordingly to the circumstance.
6. Measure and cut 2 lengths of 22/2 wire long enough to reach the destination where the camera is mounted. One cable will be for audio; the other will be to power the Verifact A. Label both ends of each wire accordingly.
7. Using glow rods or fish tape, fish the network drop and 2 sections of 22/2 audio cable down the drywall.
8. Mount the Axis P3374/3375 base to the wall using the screws associated with the anchors.

Drop Ceiling Inscructions

1. Remove the ceiling tile the camera will be mounted to and determine where on the tile to mount.
2. Using a pencil, mark the two holes where the camera base well be attached
3. Make a small hole that can be hidden by the camera dome for running cabling through.
4. Using toggle bolts, mount the camera.
5. Return ceiling tile with mounted camera to drop ceiling.

Connecting the Wiring

1. Strip the jacket off the 22/2, revealing the red, black, and common (bare wires) on both cables. 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 the cable we ran for power, remove the common (bare wire) completely.
2. Cut a 3.5 mm audio cable in half. Strip about an inch of the black jacket; then strip about 1/2 inch of red and white strand jacket. Test the 3.5 cable for polarity (touch one end of the cable tester to the tip of the 3.5 jack and the other end to the red and white wires. This will be the positive wire; the middle section of the 3.5 jack is negative wire; the bottom section of the jack is ground/stranded wire.) Splice these wires with the camera end of the 22/2 cable ran for audio.
3. Connect the power cable to the IO phoenix connector (Red to 2, Black to 1).
4. Plug in the network drop to the PoE NIC, the 3.5 jack into the pink AUDIO IN port on the camera, and the IO Phoenix connector to the IO port.
5. You will also need to cut another shorter piece of 22/2 cable (approx. 1 inch). Strip the jacket 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 jacket (See picture).

   

Connecting the STM-1

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

   

2. Connect the other end of the 22/2 we ran for power to the PWR terminals (Red to +, Black to the other terminal) of the STM-1.

   

3. Connect the cable we ran for audio to the LO-Z OUTPUT terminals (Red to +, Black to -, ground/strand to the other terminal) of the STM-1.
4. We will need another length of 22/2 cable intended for your microphone; connect it to the input terminals of the STM-1 (Red to +, Black to -, ground to the ground 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, duplicate these steps to get to the 2nd camera. LO-Z output can feed 2 cameras, but no more. If there are 2 Shure MX202i Microphones, duplicate steps. An STM-1 can power and gather audio from 2 Shure 202i mics.)

Connecting and Mounting the Microphone

1. Asses the drop ceiling to decide best mounting placement for the MX202i. Avoid tiles adjacent to HVAC or fire safety devices.
2. Drill a hole into the center of the single gang plate using the ½” paddle bit (if not prefabricated).
3. Measure center of the drop ceiling tile and drill a similar hole with the ½” paddle bit.
4. Align the single gang plate to the location of the microphone on the drop ceiling tile using a pair of toggle bolts.

   

5. Run the MX202i through the ½” hole in the ceiling tile and single gang plate with the rubber stopper to secure the microphone in place and plugging the ½” hole .
6. Adjust the length of the cable of the microphone to a desirable length, hiding the remainder in the ceiling near the STM-1. Attach the windscreen to the MX202i.

   

7. Run the XLR mini cable to the STM-1 location.
8. Connect the connect the XLR mini to the 4 pin Male XLR adapter.
9. Strip away a portion of the red and black cables inside the pigtail, revealing the copper wire inside.
   • The microphone will be connected via the input terminals of the STM-1 (Red to +, Black to -, ground to the ground terminal).
10. Connect the female XLR to the Male XLR adapter
