Description
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

CCTV Design Lens Calculator is an useful tool for CCTV design.
Along with the traditional function of many Lens Calculators - calculation of the field-of-view size depending on the distance and lens focal length, CCTV Design Lens Calculator offers several new, more effective tools.

CCTV Design Lens Calculator  allows to:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Choose the most suitable lenses, heights and locations for camera installation to provide the required parameters of view areas.
 
Calculate the horizontal projection sizes of view areas to draw them on the location plan.
 
The calculation of the projections are performed ??in 3D coordinate system, depending on parameters and height of the camera, required range of heights and the maximum distance of video surveillance. It is convenient to use the resulting projection to draw them on the location plan during CCTV design in any graphics program.

Choose the optimal camera resolution for specific tasks.
 
Calculate distances from the camera up to which the specified criteria of spatial resolution (pixel density) and field-of-view size are satisfied. It is convenient to mark these distances on the obtained projections during CCTV design in any graphics program. The default values ??of these criteria of spatial resolution correspond to the five regions according to the CCTV Operational Requirements Manual 2009: Monitor and Control, Detect, Observe, Recognize, Identify.
 
Calculate values of spatial resolution (pixel density) and field-of-view size at specified distances from the camera. 

Visually, using automatically scalable pictures, estimate details of images of various objects at specified distances from the camera or with specified values ??of spatial resolution (pixel density). CCTV Design Lens Calculator contains photos and models of people and a car with license plate. You can add your own pictures.
 
CCTV Design Lens Calculator allows to model images from megapixel cameras, up to hundred of megapixels using  PiP (Picture in Picture) technology.
 
The Lens Calculator has Digital ZOOM tool for more accurate estimation of resolution.
 
CCTV Design Lens Calculator allows to export the results of calculation and models of images as screenshots in formats *. bmp, *. jpg, *. gif, *. tiff, *. png. You can also copy the results and images to the  clipboard.
 
CCTV Design Lens Calculator can operate metric (meters) and imperial (foot) measurement systems.

Limitations:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
CCTV Design Lens Calculator calculates the spatial resolution by a simplified way, along the main optical axis of the camera. Height of the camera, camera tilt angle and height of measurements of the spatial resolution are not taken into account. These parameters are used only for calculating the view area projections.
 
When modeling resolution only the number of pixels is taken into account. Other factors affecting the detail of object images (compression, lens resolution, contrast, noise, etc.) are not counted.  Thus, the models demonstrate the maximum achievable image detail of an object under the given conditions. The real image of the object may be less detailed.
 
If necessary, you may consider some of nonregistering factors using corrective factors, or use much more powerful CCTV design software - VideoCAD.
 
In modeling spatial resolution using pictures, the simulated spatial resolution can not exceed the spatial resolution of the pictures.


Installation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1. In case your operating system is Windows 2000 or Windows XP, Windows Vista, enter  under administrator account (administrator account is required only at installation).
2. Unpack archive in case CCTV Design Lens Calculator was supplied in archived file.
3. Stop all running programs. Especially antivirus and Windows registry monitoring software.
4. Start Setup.exe.
Further program installation is performed automatically.
5. If your operating system is Windows9x or Windows Me, reboot your computer.

CCTV Design Lens Calculator provides detailed help system. Pressing F1 launches context help.
All elements are supplied with pop-up hints appearing at pointing by the cursor.
