Sigma Dp 1 Must Know

Sigma was showing off their digicam slab of tech, the DP1. To the untrained eye, it doesn't look like much. But Sigma's put the same 14.1-megapixel APS-C sized Foveon CMOS sensor used in its SD14 DSLR into this tiny package. There's a f/4, 28-mm (in 35-mm equivalent terms) lens, but what really impressed us was the build quality on this unit -- not a creak or bit of flex to be had on the camera. It's definitely a high-end piece of photo jewelry.

WiFi Comes To Digital Cameras - Wow! What's Next?

First we had to get over the whole film thing after a nation of baby boomers had been raised on Kodak, Polaroid, and 35mm film cameras of various shapes and sizes. We were all use to the idea of sending in our film for developing and waiting for our pictures to come back.

Then along came digital cameras and the world was taken by storm with this cool new technology. Suddenly you could take a picture and see the results immediately. At first these cameras were slow and not such great quality but still kind of cool. Then things heated up and now we have fantastic digital cameras of all sizes and shapes that can take wonderful images which can be shared instantly with your family, or the rest of the world for that matter.

Now comes the latest in technology integration. WiFi and digital cameras. No need to even plug your camera memory card into a computer, or a printer at all. Now you can buy a digital camera that transmits the images via wireless technology. Yes, that is right, a wireless connection for your image uploads.

Now, you may be among those in the population that have not even gotten their hands around the whole digital image sharing thing yet. But this promising new technology may lead us to a world of fewer cables to plug in, quicker transfer of our images, and in the case of events in the world, the ability to share images of news almost instantly.

As we saw in the recent bombings in London, folks with cell phone cameras recorded the devastation they saw in the underground and shared it with the world in almost real time fashion. These new cameras may be able to take that sort of thing to an all new level. Imagine cities that implement widespread WiFi access and photographers with WiFi cameras capturing images of news and other special events. They could transmit those images right away and let the world see them.

Here is how it works:

Nikon has released two models of digital cameras that are WiFi enabled. The idea is to be able to transmit your pictures straight from the camera to your computer or printer through a wireless adaptor. You bring up the images to transfer, hit “go”, and they get sent through the air to your printer. The Coolpix P1 and P2 will be in the $400-$550 range in pricing and the adaptor is extra.

They are competing with Kodak which released its own version of the WiFi camera in their Easy Share line of cameras this year. Kodak has already gone to making it easy to share photos by transmitting them at so called "wireless hot spots", usually cafes or stores where wireless access is sold or given away to customers. These efforts by the leading camera makers seem aimed at adding value to their already impressive digital technology.

Digital cameras continue to be hot sellers despite what some in the industry thought would be a slowing of sales this year. Many had predicted that cell phone cameras would slow digital camera sales, but this is not happening.

If you are a leading edge gadget buyer and have a wireless mindset then you may want to be first on the block to get one of these Wi-Fi digital cameras.

Outdoor Surveillance Cameras - Wireless

Wireless outdoor video cameras come in a wide variety of shapes and sizes with just as many features. Deciding which one is right for you will depend on the how you plan to use it and the environment in which it will be installed.The most important feature for security installations is the quality of the picture. With that in mind you will need to make certain the built-in wireless transmitter frequency has the capacity to deliver an exceptionally clear picture while maintaining resistance to interference. The reality is if you can’t get a clear image from your wireless camera installation you may as well same your money and use a dummy camera (believe it or not the work pretty well as a visual deterrent).

The most common frequency used in home security installations with outdoor wireless cameras is 2.4gz. At this frequency the directional point to point antenna are capable of transmitting 380 TV lines up to 7miles but the 300ft models are more than enough for most home security installations. There are some limitations to directional antenna setups. The signal can penetrate walls, floors, ceilings, but doing so will limit the distance of the signal. A clear line of sight is required for distances in the 300ft range.

Another important consideration when choose a wireless outdoor camera is the lighting conditions. If your installation requires a camera capable of extreme low light conditions you will need to keep in mind that most night vision cameras operate do not operate well outside of the 7 meters range. This is an important consideration when you decide where to mount the camera.

The camera housing is as important as the camera itself because if it doesn’t protect the hardware from the harsh outdoor elements your investment is lost. There are many good options available but we strongly suggest weatherproof Aluminum housing as the do not distort over time like many synthetic models we looked at. Aluminum housings are light weight, easy to handle and install and the hold up well in almost all weather conditions.
