    DESCRIPTION The EX49 “No-Grip” High Impact Dome Camera for a Vari Focal “Auto-Iris” lens has been engineered for surveillance in hostile environments. Compact and good looking, the camera features a smooth “no-grip” housing for protection against theft and vandalism. An aluminum housing, CNC-machined from a solid billet, with an impact resistant polycarbonate dome and locking retaining ring, make it extremely rugged and weather-tight.

  • Page 18: Section 4. Adjustments

    4. ADJUSTMENTS For optimum picture quality the camera lens must be as close as possible to the dome’s inside face, without touching. However, the foam ring around the lens should be adjusted to seal against the dome, minimizing any side light interference, but without obstructing the field of view.

  • Page 20 PTT Bracket Base Adjustment Knobs (2) Tilt Adjustment Loosen the two adjustment knobs on the PTT bracket and tilt the lens to the desired viewing angle. The adjustment knobs are also used to position the lens for proximity to the dome. See Figure 4-3 on page 15 for lens rotational adjustment.
  • Page 21 Base Linear Adjustment Loosen the locking knob and bolt in the center of the base with a crosshead screwdriver, rotate the PTT and Camera/Lens assembly to the desired position, and re-tighten the bolt and locking knob.

  • Page 24 Use a Neutral Density filter or Infra-Red Pass filter to cover the lens during focusing to simulate low light conditions on scene for correct 24-hour focusing. For camera with vari- focal lens, the camera should be focused with the lens iris fully opened to simulate the worst possible depth of field.
