Installing a video surveillance system, you need to understand what it is that the system is intended for. That may seem obvious but there are 4 core definitions of camera application

1. Observe the what is happening in an area

2. Detect the presence of people in a scene

3. Recognise a person you know

4. Detect the presence of people in a scene

Often you may actually want a couple of of the above in the same location and might be thinking that a single camera will be able to cover your requirements. Around 90% of applications you will require at least 2 surveillance cameras unless you plan to be some of those pictures you see in the news of a pixilated person, that you have zero hope of recognizing.

Designing first with a 3D CAD helps to test the scene to determine the right camera resolution, lens and location to give the desired results. This will save you relocating or replacing cameras later on.

The following video shows us how to import a site map into the 3D CAD and then place cameras on it. Even before we have created any 3D walls it is going to give an indication of the camera coverage.

Part 2 below shows how to determine the above 4 criteria based on the colored regions in the lens view area. So for ID quality of an unknown person we need to work in the reddish area. Inside the blue region you would only be able to detect the position of a person in your scene but not really know who they are along with what they are doing. It also shows how we create the three dimensional images of walls along with other structures.

The final part takes us through the comparing of different megapixel camera resolutions and what happens to the picture when you digitally zoom in. It isn’t going to be what you see on CSI shows but rather divide the resoultion by 4 every time you double the zoom.

For anyone readers who really want to understand much more about how to design a CCTV system that gives great images, take a look at CCTVdesign.com.au, where you will also find a large amount of data about licensing, installation tips and legislations.

Italy’s past shows that the citizens of that country crafted with gold for a long time. Roman history attests to this fact too and the Romans were the first to invent new ways useful for mining gold. They used hydraulic mining procedures to extract vast amounts of gold. In 25 BC, they utilized these methods especially in Spain and they began using hydraulic mining practices in Romania in the year 150 AD. The biggest Roman gold mine was onesituated at Las Medulas in Len (Spain). The mine had seven aqueducts that were substantial enough to allow Roman mine workers to operate and collect gold from the sand and earth deposit containing the gold.

The Italian economy considerably relies on the country’s gold sector. The country harvests and utilizes close to 500 tons of pure gold. Italy also produces as well as utilizes silver and copper and the amount of people who find jobs in the country’s mining industry surpasses forty thousand.

The majority of the 10,000 corporations that make up the Italian gold sector are concentrated in the following five regions of Italy, making them well known especially for gold worldwide. They are Veneto, Tuscany, Piedmont, Lombardy, Campania.

Due to the malleability of pure (24k) gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other capabilities. Alloys with lower caratage, typically 22k, 18k, 14k or 10k, contain higher percentages of copper, or other base metals like silver or palladium in the alloy.

The metal used most often as a base metal is Copper and it produces a red color. Old-fashioned and Russian jewelry contains 25% copper making eighteen-carat gold. This jewelry has a clearly different, but not strong copper tint that forms rose gold. The gold-copper alloy that is fourteen carats is similar in color to some bronze alloys. These alloys can work well in the making of police badges and other types of badges.

It is possible to make blue gold by alloying it with iron and the use of aluminum together with gold produces purple gold. However, this only happens when making specialized jewelry. Blue gold is brittle and it is therefore difficult to make jewelry using blue gold.

Gold alloys that are fourteen and eighteen carats with a mixture of silver always have a greenish-yellow look. The name for these alloys is green gold. It is possible to form white gold alloys by including nickel or palladium.
