As you probably know, these days, there are all kinds of cameras designed for different purposes. From digital and photo cameras to hidden or tiny spy cameras. Theres one more type of cameras that has gained popularity over the long years. It is called a pinhole camera.

What is a Pinhole Camera?

A pinhole cam is a simple camera without lens. Its a small box or can with a tiny (usually 0.5mm or smaller) hole inside one end and a piece of photographic paper in the other. The image is build by light passing through the hole. Although in the early days, pinhole cams did not have very clear image quality, these days there are pinhole cameras come with micro lens and provide very good image quality.

The first pinhole camera was built in the 19th century. It gained some popularity and that time. Although cameras have advanced in size and quality, the principles still remain the same.

Therefore, nowadays there are many enthusiasts who still prefer to build a pinhole camera themselves. This might be fun for amateurish purposes, however, for more serious tasks such as secret surveillance, an already built pinhole cam is much better choice.

How to Build a Pinhole Camera?

If you still prefer to build a camera yourself, then here are the basic steps you should look at. First, youll need a cardboard with a tape hinge , which can be used as a shutter. Second, youll need to make a pinhole. Simply take a needle (small in diameter, about 0.5mm) and punch through a piece of tinfoil. Then tape that piece to the inside of the box through a larger hole.

If youd like to change the angle of the view, you might want to create a moving box. You can simply take a sliding film holder so that the distance between the film and the pinhole can be changed.

If youll move a film closer to the pinhole, youll get a wider angle of view, but shorter exposure time. Moving a film further from the pinhole will result in longer exposure time, but the angle of view will be narrow.

More Serious Use of Pinhole Cameras

Actually, pinhole cameras may be used not only for taking photographs. They may be used for video recording too. However, making such pinhole video camera yourself would be very difficult if you dont know the technical side involved.

What is a Wired Security Camera

Many people these days are considering some sort of security system for their home or business. Home security systems have usually been more traditional and have consisted of alarms and sensors.

Nowadays, though, complete systems with high-tech cameras and monitors are actually very reasonable in cost in many instances.

Such costs can depend upon the kind and types of cameras, for one, and a wired security camera should be something that’s learned about.

In terms of security systems, most are classed as either “wired” or “wireless.”

Wireless cameras use an electronic signal to relay what they “see” to the monitor/receivers where the images are converted to render the signals they’ve received into usable pictures.

A “wired” camera is, of course, a camera that’s hard-wired from the camera to the monitor and recording systems. This means it’ll be hooked to the monitors and recorders through what are called “television cables,” which are special wire implements needed to transfer the image taken in by the camera, converted to a signal and then sent along the wired path to monitors and recorders, where the signal is decoded and then displayed as a picture.

Both systems have their advantages and both have a few downsides.

A wired security camera, being as it’s physically connected via means of wires and cables to monitors and recorders, won’t suffer from loss of signal strength or blockage, which can occur with a wireless camera.

Many wireless cameras have limited ranges and while some can send their signals up to a thousand feet, most are restricted to about one-hundred.

A wired camera also is less expensive than a wireless camera, which is more mechanically and technologically complex (though as the technology becomes more common costs have been declining).

Additionally, there’s no signal interference or blockage with a wired security camera, no matter how far from the monitors the cameras are.

Possible downsides of wired cameras can include the fact that wires can be unwieldy or unsightly and that there’s just no way to optimally place a wired camera in certain locations.

When looking at any specific security camera and system, try to look at the size of the area to be monitored.

If it’s relatively compact but has spots where wires just don’t need to be visible it could be that a wireless system may work best.

However, if there’s a great deal of area to be put under video surveillance and wires and the like aren’t an issue but cost is, a wired security system is probably the best bet.

Always check on the placement of the cameras to be installed, the budget available for the system and the overall area to be monitored.

Factoring in all three elements and then looking at what the pluses and minuses of each system appears to be can help a person considering purchasing one to come up with the best choice for the specific circumstance.

Thermal Imaging Cameras Its Applications And Usage

Temperature is measured in many ways and has many applications in our everyday lives; like checking for a fever, overheating of appliances, room temperatures, weather and many others. Thermal imaging cameras, on the other hand, have another way of measuring temperature. Instead of providing the user the exact reading of temperature, thermal imaging cameras provide the user with a visual reading where the level of temperature is shown by colors. These pictures provided by these cameras are produce by rapid firing of infrared lights for a quick scanning of an area and recording the temperature in every space by means of color; red for hot, blue for cold and green or yellow for neutral.
The Use of Thermal imaging cameras

Thermal imaging cameras are used in many ways. These are primarily used to detect and diagnose problems that have something to do with thermal patterns such as poor insulations or overloaded circuits. Thermal imaging cameras are used in international airports as well to detect passengers with fever or illness.

It can detect moisture
It can detect plumbing leaks

The same function applies but thermal imaging binoculars have more scope and range. It commonly used by soldiers or people in the army. It acts as night vision as well for we are all aware that body heat is emitted by us.

Thermal scopes

Thermal scopes are like thermal imaging binoculars but are created specifically to be attached to something usually a rifle. Like the thermal imaging camera and binocular, thermal scopes detects heat and can give you a visual with respect to the heat on a certain thing.

Now, there are many questions about the capability of thermal imaging technology. One of which is if it can see through walls. Well, when you use a thermal imaging device, you might have a photo of an outline of a wall or a post but actually these are created because of the heat that is on an objects surface.
