When to use an Infrared Security Camera in your Security System Setup

By Chad Buie

If you need to capture security video in the dark, you need an infrared security camera. Infrared security cameras have advantages and disadvantages that must be considered when designing a security system.

Let's start out by acknowledging a infrared security camera's obvious drawback: they capture black and white video. With that said, we can begin to speak about the benefits of having an infrared security camera in your security setup and the different types of infrared cameras.

An infrared security camera has the ability to capture video in conditions where other cameras cannot capture anything. Faced between having black and white video is better than having none.

Many closed caption television security system cameras hinge on having good available lighting. Often times this means that a thousand dollar setup can many times be rendered useless and ineffective by simply removing the light source, by either destroying or disabling the light. In this situation a infrared security camera would make an excellent failsafe. Secondly, many times the lighting necessary to properly secure an outside location would be overwhelming to nearby residents or businesses, draw unwelcome attention, or otherwise be undesirable. This is another situation where a infrared security camera would be very beneficial.

How do Infrared security cameras work? Infrared Sensors (or IR) detect infrared radiation, which is essentially the byproduct of heat. Specifically, electromagnetic radiation has a wavelength longer than visible light but shorter than a microwave, which means that people cannot see it or be damaged by it. Infrared (or thermal) imaging is used in many devises such as smart missiles, night vision goggles, and television remotes. Other scientific uses involve using infrared light to predict the weather or study the formation of stars. Obviously, visible light is not necessary to produce heat, which is why infrared cameras work so well at night.

Infrared cameras come with many different numbers of infrared lights built into the lens. Some have as many as 64 or as few as 6 bulbs, but the number of bulbs is not the only thing to consider. The size of the infrared bulb is important as well. Generally the more infrared light, in both size and number, that a infrared security camera has the farther that you will be able to see with the camera.

When it comes infrared cameras if the cameras has 12 or more bulbs, it was not meant to be used indoors. This is because many flat glossy surfaces can reflect the light back and overwhelm the sensors. A few examples of these types of surfaces include windows, doors, coffee tables, even walls painted with "glossy" paint finishes can wash out an infrared sensor if it has too much light. It is better to know where you will install the camera rather than just assuming that more lights equal a better picture.

Video surveillance systems can be used in many instances and they provide an accurate record of activity going on under their watch. Video surveillance is a great idea for a business owner who is not at their business at all times of the day to watch what is going on in their business during the hours when they are open.

Since the initial launch of a company to publicize its own underwater camera, camera giants and several colleagues made their own brands as well. For each year, countless underwater cameras have been added, changed or improved making a new mark for each. In fact, if you do a Google search for a specific camera, including the waterproof ones, it will issue over a million hits and hundreds of brands.

Digital Camera Binoculars Best Of Both Worlds

By Riz Goodman

The big burden of carrying all the things on a hunting expedition can be a pain and that is why it is better to have a few things combined. One such thing is the digital camera binoculars. These are the binoculars as well as the digital camera combined. This helps as you can easily click a picture of the object that you are about to hunt. In fact another major thing that is going to happen here is the fact that you have that special video camera feature built in for instant replay which helps in capturing the video footage easily.

There are a couple of things that you should know when you are selecting the binoculars with an in built digital camera. The first and foremost thing that you should be worried about is the resolution. Now be aware that this resolution will be different than the resolution of the binoculars. Always go for more 1 mega pixel resolution. Also check if the binoculars have the play back facility of small videos. A lot of binoculars come with the instant replay feature.

The digital cameras generally have a memory which is not capable of storing many pictures and it would be better to have some sort of the external memory and the best thing to do in that case is that to buy external memory. The way to buy external memory is to buy the SD memory card.

The general view is that binoculars with digital cameras are not that worth the price but with recent technological advancements all good manufacturers have come up with a variety of better features and styles.

It is generally a very good practice to go into a nearby binocular retailer shop and check the quality of the binoculars and also check how it adjusts in your hand. These binoculars are very heavy and need a good grip.

Make sure that if you are a photo enthusiast then you should go only with digital camera binoculars.

What You Should Know Before Buying a Digital Camera

By Daniel Henderlei

The key technical component of digital photography is the semiconductor. Light is focused onto a semiconductor, creating a digital image. Digital images have let us enter a new paperless age of photography as images can be stored on computers instead of printed.

Talk to those you know who own digital cameras before buying one. Friends and family can offer the best advice, and tell you which brands and models they favor or are disinclined towards. You can make a sound purchase when combining their experience with what you read on the Internet.

For nature lovers who take photos of the great outdoors, a large zoom lens is very helpful. For those of you want to shoot photos of their kids involved in an activity, a fast response time is key, as children move around quickly. For set photos where family and friends are posing, you'll probably want a model that takes pictures in dim light.

For digital cameras, you've got the Point-and-Shoot and the Digital SLR. If you're a novice stick a simple model that's well-rounded - resist the temptation to splurge your money on a super-advanced camera, because you'll be paying for a lot that you'll never use. By the time you learn to use it, you'll probably be wanting another camera with even more cool features.

The Point-and-Shoot camera

Beginners will like the point-and-shoot. It lives up to its name as most settings are automatic, and will adjust itself for you based on the environment and lighting. Customization can still be available as many cameras offer presets for environments like sunny, outdoors, indoors, etc.

Use automatic settings when you want the light sensitivity (ISO) and focal length calculated for you. Read around to find which cameras are best at this.

The Compact is slim, and ranges in size from pocket cameras to ones than fit in a purse. Most compacts have wide-angle and zoom lenses, blur reduction, image stabilization, scene mode pre-sets, and face detection. They can also have LCD displays that are large despite the smallness of the camera.

For distant subjects, check out Optical Zoom cameras. They capture small details, and can crop a scene easily. Optical Zooms have a feature where the camera lens is physically adjusted to improve image quality, with a natural-looking image. Digital Zoom crops the image and then enlarges it to fill the frame - this affects the quality and clarity of the image. Cropping can also be done easily on your PC.

Digital SLR Cameras (Single Lens Reflex)

Digital SLR cameras are for advanced users - those who want to manage and control what the camera does, rather than just point and shoot. SLRs can offer interchangeable lenses, and have a myriad of manual controls. Many settings can still be automatic, but an SLR is best for those who want hands-on control instead of automatic settings.
