Lenses for Industrial Cameras

Choose the perfect lens for your industrial camera

The lens is the "eye" of every industrial camera. It determines what area will be monitored (angle of view) and how detailed the image will be (zoom). Choosing the right lens is crucial for the effectiveness of the entire CCTV system. At Actii.pl, we offer lenses to meet every challenge.

Types of lenses in our offer:

To help you choose, we have divided our offer into several main types:

  • Fixed Lenses: Have a constant, unchangeable angle of view (e.g., 2.8mm, 4mm, 6mm). Ideal for where the monitoring area is predefined.
  • Varifocal Lenses: Allow manual adjustment of the angle of view and focus (e.g., 2.8-12mm). They enable precise framing during installation.
  • Motozoom Lenses: Advanced lenses with remote adjustment of focal length (zoom) and focus. Ideal for PTZ cameras and locations requiring dynamic frame changes.
  • Auto-Iris Lenses: With automatic aperture adjustment, which adapts the amount of incoming light. Essential for outdoor cameras exposed to changing lighting conditions.

How to choose the focal length?

Remember the rule: the shorter the focal length (e.g., 2.8mm), the wider the angle of view, but fewer details of distant objects. The longer the focal length (e.g., 12mm), the narrower the angle of view, but much greater magnification of distant details. At Actii.pl, we will help you choose the lens that perfectly matches your camera and requirements.

    Fixed Focal Length Lenses for CCTV Cameras

    Fixed lenses for industrial cameras are the primary type of lens used in monitoring. They are characterized by a set, unchangeable focal length, which translates to a constant angle of view for the camera.

    They do not have focal length (zoom) adjustment. They are available with manual iris adjustment (Manual Iris) or without adjustment.

    How to choose a fixed lens?

    The choice of focal length depends on how wide an area and from what distance you want to monitor:

    • Wide-angle lenses (e.g., 2.8mm, 4mm): Offer a wide field of view, ideal for monitoring small rooms, corridors, or a general overview outdoors. Objects appear smaller and more distant.
    • Standard lenses (e.g., 6mm, 8mm): Provide an angle of view similar to the human eye.
    • Narrow-angle / telephoto lenses (e.g., 12mm, 16mm, 25mm): Allow for significant magnification of distant objects, but at the cost of a very narrow field of view. Ideal for monitoring gates, entrances, or specific points from a long distance.

    Our fixed lenses fit most industrial cameras with a standard CS-Mount.

  • Varifocal Lenses Zoom

    Precise Frame Adjustment – Varifocal Lenses

    Varifocal lenses with manual iris adjustment are the most flexible solution for industrial cameras. They allow for manual and precise adjustment of the image zoom (focal length) and focus during camera installation.

    This gives you full control over the frame – allowing the camera to see exactly what you want it to see, without needing to physically move the camera closer or further away.

    Advantages of varifocal lenses:

    • Flexibility: One lens (e.g., 2.8-12mm) covers the range from a wide angle to a significant zoom, making selection easier.
    • Precision: Ability to accurately "frame" the monitored area, such as an entrance gate, door, or parking lot.
    • Versatility: Ideal for situations where it is difficult to precisely determine the required fixed focal length before installation.

    Zoom and focus adjustments are made manually using rings on the lens. These are the most frequently chosen lenses by professional CCTV installers.

  • Auto-Iris Lenses

    Excellent Image in Changing Conditions – Auto-Iris Lenses

    Lenses with an Auto-Iris (Automatic Iris) function are essential for cameras operating in locations with highly variable lighting, meaning primarily outdoor cameras.

    These lenses have a mechanical iris control that is connected to the camera. The camera, by analyzing the amount of light hitting the sensor, automatically closes or opens the lens iris. This allows for a properly selected exposure to be maintained in all lighting conditions. The image will not be overexposed (in full sun) or too dark (at dusk).

    Types of Auto-Iris control:

    • DC-Iris: Control is current-based, directly from the camera. This is the most popular standard today.
    • Video-Iris: Control is based on the video signal. An older standard, less common.

    Auto-Iris lenses are key to obtaining high-quality images from outdoor cameras around the clock. We offer fixed and varifocal lenses with the Auto-Iris function.

  • Motozoom Lenses

    Remote Frame Adjustment – Motozoom Lenses

    Lenses with a motozoom function are the most advanced type of lens for industrial cameras (not including integrated PTZ cameras). They allow for automatic and remote control of zooming in and out (wide), as well as automatic focusing (Auto-Focus).

    Control is most often handled via the camera's interface (e.g., over the network in IP cameras) or through the recorder (e.g., using CoC control in analog HD systems).

    Advantages of motozoom lenses:

    • Installation Convenience: The installer can precisely set the frame while looking at the monitor at the recorder, without needing to climb the ladder to the camera again.
    • Remote Correction: If the client's needs change over time (e.g., they want to monitor a different part of the lot), the zoom and focus can be changed remotely.
    • Precise Auto-Focus: Guarantees a perfectly sharp image after every focal length change.

    We distinguish between motozoom lenses with automatic iris adjustment (Auto-Iris), which are essential for outdoor use, and those without Auto-Iris (for indoor use).

  • Lenses for board cameras

    Compact Board Lenses (M12 / S-Mount)

    Board lenses, also known as S-Mount or M12 lenses (from the 12mm thread diameter), are small, compact lenses designed for direct mounting onto the camera's sensor board.

    They are most commonly used in:

    • Dome cameras: Where small size is important.
    • Outdoor cameras with IR diodes: Many compact "bullet" cameras use this type of lens.
    • Miniature and hidden cameras: Due to their small dimensions.

    Like larger lenses, various focal lengths are available (e.g., 2.8mm, 3.6mm, 6mm), which determine the camera's viewing angle. Many are also IR Corrected to ensure a sharp image both day and night.

  • Megapixel Lenses

    Sharpness and Detail for IP & HD Cameras

    Megapixel cameras (IP, AHD, CVI, TVI) with high resolutions (Full HD, 2MP, 4MP, 5MP, 4K) require special lenses capable of transferring such a large amount of detail to the sensor.

    Megapixel Lenses are designed specifically for use in IP and analog HD cameras. Using a standard lens (designed for analog SD cameras) on a high-resolution camera would result in a blurry, unsharp image that wouldn't utilize the camera's potential.

    Why choose a megapixel lens?

    • Higher Optical Resolution: Better quality glass and more precise construction.
    • Edge-to-Edge Sharpness: Ensures a sharp image from the center to the edges of the frame.
    • Better Color Rendition: Reduced chromatic aberration.

    In our offer, you will find fixed, varifocal, Auto-Iris, and motozoom megapixel lenses that will allow you to fully exploit the potential of your high-resolution cameras.
