Silent and stable operation
The STC-3915 domes are equipped with low-noise high-precision pan/tilt gear, including stepping motor, which provides 0.024° accuracy and eliminates mechanical vibration. In traditional Speed domes, low-frequency vibration and any environmental impacts often cause a shift of the preset pan/tilt position. To compensate this negative effect, the cameras use special technology. The cameras maintain high preset accuracy even over a long operating time.

DSP Sony Effio-E – Ultrahigh Resolution
Due to use of Sony SuperHAD II CCD and Effio-E digital signal processing, the camera provides extremely high image detail, as well as superior color rendering, with horizontal resolution of 650 TVL in color and 750 TVL in B/W mode.

Software Wide Dynamic Range
The WDR mode allows to provide balanced images with high level of detail, even when intensity of illumination within image varies excessively (e.g., if an indoor camera is pointed towards a window) or if camera is blinded by car headlights. This is achieved due to use of Effio-E digital signal processor.

Day-and-night surveillance
The STC-3915 is equipped with mechanical IR cut filter, which allows to use the camera day and night. In color mode, the STC-3915 features 0.5 Lux minimum scene illumination. When light level is reduced, IR filter is removed, the camera switches to B/W mode, providing minimum scene illumination of 0.2 Lux/F1.6.

In extreme low-light environment, the cameras can activate Frame Integration mode. In this mode, longer exposure time allows the CCD elements to accumulate more charge.

The cameras are perfect for outdoor video surveillance systems. The STB-C103 outdoor housing (IP66-rated) allows wider operating temperature range of up to –40° C … +50° C.

Camera setup
The STC-3915 supports a wide range of settings and features, allowing to provide most effective video surveillance, patrolling, and moving object tracking.

36x optical zoom, implemented in STC-3915, allows to recommend the camera for observing objects at very big distances (e.g. for industrial site perimeter surveillance), as well as for use in systems with increased requirements to image detail. The cameras provide 360° pan (continuous pan rotation) and 180° tilt (Auto Flip mode). You can configure up to 200 presets, set up to 8 patterns (total 480 sec) and up to 8 preset tours, and create up to 16 privacy zones. Camera pan speed between presets can reach 350°/sec.
