Unique model number in the base of models. At the moment of new model creation the number is generated automatically.

Model name.

Producer of the model.

Key feature of the model.

Television system (CCIR/PAL, EIA/NTSC). Not used for digital (IP) cameras (N/A).

If EIA/NTSC is chosen, then maximal exposure time sets to 1/60s, or else 1/50s.

Standard camera, PTZ camera, dome camera, mini-camera, auto-dome camera.

If the Display camera type box (on the Camera and Illuminator tab in the Options box) is checked:

•	If PTZ or auto-dome camera is chosen, icons of cameras of this model in the Graphics window will correspond to PTZ camera .

•	If mini-camera (mini or mini-dome) is chosen, icons of cameras of this model in the Graphics window will correspond to mini-camera.

The icon type is influenced by Protection parameter as well.

Output type of camera.

B/W (black&white), color, day/night (removeble IR filter) easy day/night (permanent IR filter).

At illumination reduction day/night and easy day/night cameras are switched into black-white mode.

Color parameter influences 3D model color as well as spectral sensitivity of cameras to various light sourses.

Image sensor model. If ExView HAD ™ CCD is chosen, in calculation of illumination from different light sources special factors will be used, considering increased relative IR spectral sensitivity of such image sensor.

Image sensor format. The format is connected with physical size of image sensor active area. For nonstandard image sensors it is possible to specify horizontal and vertical sizes, in millimeters, separated by an asterix, for example: 4.8*3.6.

The format is important in calculation of view angles.

See also: Image sensor format

Horizontal and vertical numbers of effective pixels of the image sensor.

Number of pixels is used in modeling image resolution and in calculation of person detection, identification and license plate reading areas.

See also: Number of pixels

Interlaced or progressive. Analog cameras always have interlaced scan. Digital cameras can have progressive scan.  

Progressive scan is preferable.

Modeling interlace distortion can be enabled separately in camera parameters. This parameter of camera model does not affect the simulation of interlace scan .

Ratio of the horizontal image size to the vertical size: 4:3 or 16:9.

You  can enter decimal number or a ratio separated by colon, for example 16:9.

All analog cameras with standard video signal have 4:3 Aspect ratio.

Some IP cameras have 16:9 Aspect ratio (wide-screen image). Some IP cameras allow to switch Aspect ratio between 16:9 & 4:3.

This parameter is used for modeling distortion of moving 3D models and rotating Rotakin object arising from the Rolling Shutter effect.

As a result of Rolling Shutter work, exposure of different rows of the image sensor begins and ends sequentially at different times, which causes a horizontal shift of moving objects.

This effect occurs with many IP cameras with CMOS image sensor and doesn't occur with cameras with CCD image sensor.

Row time (microsecond) is the time period (in microsecond) between the beginning of exposure of adjacent rows. Unfortunately this parameter is not given in the cameras' specification. To elucidate the value of the parameter you should contact the manufacturer or measured this time in practice.

Horizontal resolution of the camera, in TV-lines. At 3D modeling horizontal resolution of image will be limited up to the value set in this box.

If N/A is chosen in the box, then resolution limitation is disabled.

Items sharp+1, sharp+2, sharp+3 on the contrary increase image sharpness. With the help of these items it is possible to model effect of Aperture corrector.

Aperture corrector is automatically switched-off at insufficient illumination.

Many of megapixel cameras have limits of frame rate, which depends on image number of pixels. The maximal frame rate of analog cameras is 25 fps (PAL) and 30 fps (NTSC).

For cameras of this model you can't set frame rate more than the Maximal frame rate.

Maximum signal/noise ratio. Unweighted value.

See more: S/N max.

In VideoCAD it is meant, that scene reflection factor is 0.75, light source - halogen incandescent lamp (color temperature 3100 +-200K) according to Standard CEA 639 'Consumer Camcorder or Video Camera Low Light Performance'.

For day/night and easy day/night cameras in this box it is necessary to enter the minimum scene illumination in black-white mode.

For unambiguous description of sensitivity in VideoCAD, should be pointed also:

In VideoCAD the minimum illumination is specified at maximum exposure time.

See more: Min. illum. (lx)

Exposure time (milliseconds) at which the minimum illumination has been measured.

Parameter is sometimes given in camera specifications. For analog cameras typically value is 20ms (PAL) or 16.5ms (NTSC). For IP cameras and analog cameras with light accumulation the exposure time may be up to 200ms or more.

At modeling the exposure time assumed the truth of the Reciprocity principle, that is inversely proportional of sensitivity to the exposure time.

See also: at exposure (ms), modeling exposure.

Lens aperture at which the minimum scene illumination is measured.

The parameter is given in camera specification. Typical value from F1.0 up to F2.0.

Signal/noise ratio of the image at the minimum illumination, unweighted value.

According to CEA 639, limit value of signal/noise ratio at the minimum illumination determination is 17dB (7 times in voltage).

IRE of video signal at minimum illumination, at AGC switched on by default.

In VideoCAD 100 IRE corresponds full peak-to-peak amplitude of video signal and accordingly to maximum brightness amplitude on the image. 50IRE corresponds half of maximum brightness amplitude on the image, etc.  

The parameter is given in camera's specification. Typical value is from 30 to 50.

Exposure time limits within which electronic shutter operates.

The parameter is given in camera's specification. Modern PAL system cameras have exposure limits 1/50s-1/100000s. For cameras of NTSC system the maximum exposure is 1/60s. For IP cameras the maximum exposure time can be larger, up to several seconds.

In this cell it is possible to specify Maximum AGC gain (dB) for cameras with switchable AGC gain: High AGC gain (High AGC, S-AGC, Super AGC) or LO AGC gain.

The box will be enabled and the set AGC limit will be considered in modeling, if the Set box is marked.

Enter in the cell maximum AGC gain if it is given in the camera's specification.

Typical value is 26-42dB.

If the camera does not have switchable AGC gain, the maximum AGC gain is calculated by the program.
