1 Purpose and Functions
The ACTii AC6328 infrared illuminator is a professional device designed to drastically improve image quality in CCTV monitoring systems operating at night or in low-light conditions. The use of modern ARRAY IR diode technology allows for a clear and sharp image even in total darkness, which is a key factor in the effectiveness of security systems.
The device is enclosed in a robust, vandal-resistant aluminum housing, which, combined with the IP66 ingress protection rating, makes it suitable for outdoor use regardless of weather conditions. The illuminator features a built-in twilight sensor that automatically activates the IR diodes after the ambient light intensity drops, ensuring maintenance-free operation and energy efficiency.
Main features:
- ✔ High-quality, powerful IR Array diodes (4 pieces) ensure uniform illumination
- ✔ Solid aluminum housing resistant to mechanical damage and weather conditions
- ✔ Special mounting bracket allowing for aesthetic concealment of the power cable
- ✔ Long illumination range of up to 45 meters
- ✔ Wide 45-degree beam angle, perfectly matched to standard camera lenses
- ✔ Built-in automatic twilight switch
- ✔ High IP66 ingress protection rating ensuring full protection against dust and strong water jets
Control and connection information:
The device operates in automatic mode. Thanks to the integrated photoresistor, the illuminator turns on automatically when the light intensity falls below the operating threshold. Connection is made via a standard 2.1mm/5.5mm DC jack located on a 56 cm long cable.

3 Installation and Mounting
Installation steps:
- Select a mounting location that ensures optimal illumination of the area monitored by the camera. Remember that the beam angle is 45 degrees.
- Use the bracket as a template to mark the mounting holes on the wall or other surface.
- Attach the illuminator using appropriate expansion anchors and screws (not included, must be selected based on the surface type).
- Loosen the adjustment screws on the bracket to set the desired illuminator angle, then tighten them.
- Connect the 12V DC (min. 700mA) power supply plug to the illuminator's DC jack. It is recommended to protect the connection from moisture (e.g., in a junction box), despite the device's ingress protection rating.
4 Safety and Maintenance Instructions
Safety rules:
- Use only stabilized 12V DC power supplies with a current capacity of at least 700mA. Improper power supply can damage the LEDs.
- Do not look directly into the IR diodes from a close distance when the device is turned on. Even though infrared light is almost invisible to the human eye, it emits energy that can be harmful upon direct exposure.
- Disconnect the power supply before performing any maintenance work.
- Do not dismantle the device housing – doing so risks loss of seal and warranty.
Maintenance:
To ensure maximum illumination range, the front glass panel must be cleaned regularly. Dust, spider webs, and other contaminants can significantly limit infrared light emission. Clean with a soft, damp cloth without the use of aggressive detergents.
5 Troubleshooting
| Problem | Possible cause and solution |
|---|---|
| Illuminator does not turn on at night | Check the power supply and the correct connection of the DC plug. Ensure that the voltage is 12V. Check if the twilight sensor is not being illuminated by another light source (e.g., a street lamp). |
| Illumination range is less than 45m | The range depends on the camera's sensitivity and the reflection coefficient of objects in the field of view. Clean the illuminator glass. Check if the power supply provides the required 700mA. |
| Camera image is overexposed (white spot) | The illuminator is aimed too close to an object. Change the illuminator angle or increase the distance from the monitored target. |
