PRODUCT VARIANTS FOR SKYRS PAKISTAN

SKYRS distributes all operational variants of this 2.8-12mm non-IR series across Pakistan to fit varying system requirements:

  1. 13VG2812AS-SQ (DC Auto-Iris): The baseline model featuring an integrated 4-pin square connector. It dynamically adjusts the aperture size based on incoming light levels, making it ideal for standard indoor/outdoor areas with changing light.

  2. 13VM2812AS (Manual Iris): The manual variant configured without the automated cable assembly, designed explicitly for constant-illumination indoor environments, retail displays, and controlled laboratory test benches.

DEPLOYMENT, INSTALLATION, AND CONFIGURATION

Professional on-site handling ensures mechanical longevity and flawless optical alignment during integration.

Mechanical Installation Steps

  1. Lens and Mount Check: Verify the camera body is natively a CS-mount. If a 5mm C-mount adapter ring is present on the camera, remove it before threading.

  2. Attachment: Align the threads of the 13VG2812AS-SQ to the camera’s mount ring. Rotate clockwise carefully until the lens seats firmly. Do not use excessive force.

  3. Control Interface: Plug the 4-pin square cable securely into the camera’s side or rear DC-iris port.

Configuration and Tuning Workflow

  1. Lighting Simulation: Set up the camera focus during peak wide-open aperture conditions (low-light environment or via software electronic ND settings) to achieve the tightest possible depth of field.

  2. Focal Length Alignment: Loosen the manual zoom lock screw. Rotate the zoom barrel to balance the field of view—widening out to 2.8mm for wider coverage or tightening up to 12mm for a focused subject area. Re-tighten the zoom lock screw.

  3. Focus Precision: Loosen the manual focus lock screw. Rotate the focus mechanism until sharp contrast and fine lines are visible on your primary target area. Tighten the lock screw to prevent drift caused by ambient structure vibrations.

  4. Back-Focus Correction: If the image target loses focus while switching between wide and telephoto zoom extremes, adjust the camera body’s internal back-focus ring until consistent par-focal performance is locked in.
