Smartec STC-HD3925 dome camera

The HD-SDI family of the equipment for video surveillance of the Smartec trademark with fall of 2014 was filled up by the STC-HD3925 dome camera which is equipped with a high-precision turning gear with a possibility of its programming on 200 presets and 8 rounds of patrol and a zoom lens from the 30th an optical zoom. The new rotary dome camera is supplied with 2 MP sensor of Panasonic and creates the uncompressed digital image in the day/night modes with permission of Full HD/HD and the speed of 30/60 fps at osveshchennost to 0.5/0.1 lx. Besides, these rotary cameras have the WDR mode, and for reliable work at external temperatures up to -40 °C can be completed with a thermocasing.

The quality of video from STC-HD3925 adapts under illumination conditions hardware and programmatically. In particular, the dome camera is equipped with the mobile IK-filter and creates color/monochrome video at osveshchennost to 0.5/0.1 lx, and the informational content of the image at an essential lack of light is provided in the mode of a slow electronic lock at which activation the rotary dome camera transfers the black-and-white image up to 0.001 lx. Moreover, new rotary cameras can work in the mode of high dynamic range and transfer the picture balanced on brightness and contrast in the conditions of a background flare.

Video transmission from the dome camera can be performed with a speed of 60 fps when choosing permission of HD 720p (1280x720 px.) and 30 fps at the most available permission of Full HD (1920х1080 px.). At the same time the image from STC-HD3925 arrives in an uncompressed type therefore it moves on the coaxial cable without delays and artifacts. For image recording which is broadcast by the rotary dome camera the producer recommends to use the Omega series Smartec video recorders. These devices support the HD-SDI standard and allow to configure new rotary cameras of video surveillance quickly.

Smooth operation of the rotary camera is possible in premises, however for operation of STC-HD3925 in street conditions it is enough to purchase a dome thermocasing of STB-C103 which will provide it operating temperature range from -40 °C to +50 °C and degree of protection of IP66. In this case the rotary dome camera will transfer the qualitative image from a street object for the realization account of the mode "day/night", WDR and ratio signal/noise higher than 50 dB, and the zoom lens used in STC-HD3925 with a 30-fold optical zoom will allow to observe remote sections of the protected object.

High accuracy of positioning of a turning gear of the camera is provided by the precision engine with a step 0.024 ° which holds the direction of the overview of the chamber module even during the work of STC-HD3925 in the conditions of vibrations or at blows. Thanks to this engine the rotary dome camera makes the circular overview on 360 °, an inclination on 180 ° in the AutoFlip mode and almost instant movement on presets with a speed up to 300 ° / page. Program opportunities of the dome camera allow to set to 200 presets of a rotating device with a binding to multiplicity of a zoom lens and also up to 8 rounds of patrol lasting up to 480 seconds everyone.

Power supply of the camera Smartec STC-HD3925 is performed from a source of 24 V of alternating current, and power consumption is 24 W in a basic equipment and 48 W when using an optional thermocasing of STB-C103. For signal pick-up from external security sensors and transfer of commands to actuators the rotary dome camera is equipped with 4 disturbing inputs and 2 relay exits. On alarm this dome model can activate the executive equipment, turn a rotating device to the preset preset position and perform other operations.
