Frequently Asked Questions - MLA2WD211 Aigis

How do I adjust the camera's pan and tilt?

Remove the dome cover, loosen the three thumbnails, then adjust the camera bracket for pan and tilt. Tighten the thumbnails after adjustment.

What type of power supply does the MLA2WD211 require?

The camera requires 24 VAC input. Do not exceed 30 VAC. Use a Class 2 power supply.

Can this camera be used outdoors?

Yes, it is an outdoor dome. It is recommended to apply silicone sealant around the base and cable entries to prevent moisture ingress.

How do I connect video for UTP models?

For models ending in '-U', use an RJ45 connector. Refer to the pinout in the manual: pin 1 (white-orange) for video signal, pin 2 (orange) for video shield, and pins 4/5/7/8 for power.

What is the lens specification?

The lens is a 2.8-11mm varifocal AI IR lens. You can adjust the zoom and focus using the knobs on the lens.

How do I change the camera's field of view?

Turn the zoom knob to select WIDE or TELE, then adjust focus using the FAR/NEAR knob. Repeat if necessary until the desired image is obtained.

What tools are required for installation?

A special Allen wrench is included for the tamper-resistant screws. For mounting, you need #10 or M5 screws (not supplied) and a flat-blade screwdriver for terminal block connections.

Is the camera compatible with existing CCTV systems?

Yes, standard models output video via BNC connector. For UTP models, ensure the receiver is compatible with the transmitter pinout.

What should I do if the image is blurry?

First, adjust the focus knob on the lens. If still blurry, check if the desiccant is installed to prevent fogging. Also ensure the dome cover is clean and properly sealed.

How do I install the desiccant?

Keep desiccant sealed until ready. Attach it using the adhesive pad to the interior surface as shown in the manual (Figure 4). It helps reduce moisture inside the dome.

5. INSTALLATION

Attention: Installations should be performed by qualified service personnel only in accordance with the National Electrical Code or applicable local codes.

5.1 Connecting Low Voltage Power & Video Signal (Standard Models)

The wiring harness has a BNC jack to accept video coax. When mounting directly to a wall or ceiling, run power and video lines to the desired location using 3/4 inch conduit.

Caution: Before proceeding to disconnect the power at its source, be sure that the unit is of the proper voltage type for the line power.

Connect 24VAC to the unit by inserting the field supply wires into the 2-position terminal block (supplied) and tighten with a flat blade screwdriver.

Connect Video cable to the unit's BNC connector.

5.2 Connecting Low Voltage Power & Video Signals (UTP Models: part number ends in -U)

When powering the unit and transmitting video over unshielded twisted pair (UTP) wiring, ensure the UTP hub/receiver in the control room is compatible with the UTP transmitter in the camera housing. Refer to the pinout below to determine compatibility.

Pin No.	Wire Color	Pair	Utilization
1 White-Orange 2		Video	Signal
2	Orange	2	Video Shield
3	White-Green	3	Data +
4	Blue	1	Power - (Neutral)
5	White-Blue	1	Power + (Line)
6	Green	3	Data -
7	White-Brown	4	Power + (Line)
8	Brown	4	Power - (Neutral)

Figure 2 Front of RJ45 Plug

Caution: Limit UTP wire runs to 1,000 feet (\~330 meters) or less.

Feed the network cable into the housing through the rear or side conduit hole. Route the cable through the housing and plug it into the RJ 45 jack shown in Figure 4. Avoid putting any tight bends into the network cable.

5.3 Mounting and/or Servicing the Unit

Refer to Figure I.

I. Using the rubber base gasket as a template, mark the mounting hole locations on the mounting surface. The unit is intended to be mounted with four #10 screws or four M5 screws (not supplied) through the four outer holes in the base casting.
2. Install the appropriate anchors or threaded fasteners.
3. Install a 3/4-inch threaded service conduit coupling into the back conduit hole, using pipe sealant on the threads. If conduit is to enter from the side, use a 2-mm Allen wrench to loosen the set screw from the conduit hole plug. Remove the plug and reinstall it in the conduit hole on the back of the unit.

IMPORTANT: If mounting outdoors, or after servicing add a generous seal/bead of RTV or silicone around the cables (on the inside of the conduit) either at the camera or at the junction box. This will help reduce moisture accumulation in the dome over long periods of time.

1. If mounting this unit outdoors or after servicing, apply a generous bead of silicone sealant around the back of the base casting, surrounding all holes. Apply the rubber base gasket to the back of the base casting and apply another generous bead of sealant to the outer edge around the exposed surface of the gasket.
2. Place the unit into position on the wall or ceiling. Install the mounting screws securely. If sealant is used, make sure that the sealant between the wall or ceiling and the gasket forms a complete seal. Add more sealant if needed. Make all final service connections and secure the conduit.

Important Note on Service:

I. When servicing the unit reapply silicon lubricant to the rubber gasket between the lid and cover before replacing the cover.
2. When replacing the cover make sure the gasket is aligned with the housing to ensure a proper seal.

6. CAMERA POSITION ADJUSTMENT

I. Remove dome cover.
2. Loosen Thumbnails (x3).
3. Make Pan adjustment by turning camera bracket in clockwise or counter clockwise motion.
4. Tilt Lens into position, then rotate face plate to square image.
5. Tighten Thumbnails.
