Battery Devouring Digital Cameras and the People Who Love Them

Surveillance Camera Systems come in all shapes and sizes and trying to figure out which surveillance system that will fit your needs can be very frustrating, but most cameras and systems today requires very little experience to install and operate. This article describes several factors to consider before purchasing a surveillance camera system.

General things to ask yourself:

- Should I buy Wireless or Wired surveillance cameras? Wireless is much easier to install than wired. - How many cameras should you buy? Using too many cameras will be expensive, not enough will only give me limited coverage. - Should I use Indoor or Outdoor type cameras? - Does my application require recording of the surveillance activity? If not, the cost can be reduced because a DVD recorder will not be necessary. - Does my surveillance system require that I can monitor over the Internet when away from my business or home.

Let's describe the different types of surveillance cameras and systems which will be helpful to determine which one to buy depending on the type of use.

Hidden Cameras: These types of cameras are for indoor use only and come in a variety of different kinds of ordinary looking objects. For instance a small hidden camera are embedded in everyday objects like an Alarm Clock, Air Freshener, Fan, CO2 Detector or even a vanity Mirror. They are usually installed in one room and used to catch any suspicious activity in the room installed. Most of them use a 12-hour rechargeable battery pack with no wires or cords to plug in. Most all of these type of cameras are wireless but some can be wired. By far, you are better off choosing a wireless kind, which takes minutes to set up. To view or record the activity a 2.4 GHz Receiver attaches to your TV or VRC or DVR, which also only takes just a few minutes.

Surveillance Camera Systems: For business type applications you make want to consider a bundled system that includes all the components need to watch you business when you are there or way from it. Your business may need 4, 8 or 16 cameras also referred to as channels. For instance a small but location may need 8 cameras or as many as 16. They can be wireless or wired. If you are looking for an easy installation choose wireless, that way no messy wires to deal with.

A 4 Channel Wireless Complete System is also perfect for a small business or even a small house. A wireless surveillance camera system will allow you to install 4 wireless cameras to digitally record all the activity in your business. These types of systems come with a DVR with full networking capability and use a GeoVision DVR card, which allows you to view live video surveillance on the Internet. This type of system is designed strictly for indoor use only, and the perfect video recording system for smaller areas. You now have the flexibility to leave and still record activity and store and retrive for later viewing. Many businesses have a panic button they press when they see a would be thief in their store and now have the proof stored if needing to use in it in court.

For Personal Home Surveillance Camera System, there is the 4 Channel Wireless VISEC Surveillance System that is perfect for monitoring 4 rooms in a small house. The cameras that come with type of system work in day or night because of the high quality digital CCD chips that automatically switches from color to black & white in low light conditions. This type of a system requires what known as a 'quad'. A quad is an accessory to your surveillance system that splits a video monitor into 4 screens. Without a quad viewing would only be able possible with one camera at a time. This type of a system also comes with a GrabBee II. It allows wireless or hidden cameras to connect your camera(s) to your computer. The GrabBee II is the bridge between the wireless or hidden camera and your computer. This device converts analog video signal to digital through a USB port.

Designed For Simple Personal Use, there is a camera called the Cyber Eye. This infrared B/W digital surveillance camera takes pictures automatically whenever someone moves in front of it and then digitally stores the pictures within the micro-camera. You can then extract the images later on just by plugging the camera into your TV/VCR to either view or record. This type of camera is great for catching someone snooping around your house. It is so small and compact you can even put it in your car and aim it out the window. This personal surveillance camera works by changes in the picture and not motion. Video images can be even taken through glass and the wireless surveillance camera will still work like a charm. The pictures are taken at 1-60 second intervals (UP TO 680 pictures). Video images will even have the time and date stamp added to each picture.

For Outdoor Surveillance Cameras, Dome cameras are used in many places including retail stores, restaurants, casinos and apartment buildings. You can even see them at your local McDonalds restaurants. Dome cameras are simply board cameras built into a weatherproof dome housing. In addition to these surveillance cameras being weatherproof, many of these types of dome surveillance cameras are vandal-proof dome and built with protective casing that can withstand the direct hit of a sledgehammer or other brute force means to disable it. Dome Surveillance Cameras are generally wired and can be connected to a Digital DVR to record all suspicious activities.

Surveillance Camera Recording - One of the most important pieces of a surveillance system is the surveillance video recorder. Whether you have one, four, eight or sixteen cameras you have to take what those cameras see and store that video for reference or possible evidence. Obviously DVR system can record much longer than old style VCR tapes. Generally these recorders come in 4, 8 and 16 channel models. Channels refer to amount of cameras that can be attached for recording. Some units are small, some large and have different features. One of the best DVR portable surveillance camera recorders perfect for body worn & covert applications and fits easily into a purse, pocket or backpack is the DVR-9800 touted as the Worlds Smallest Wearable DVR Recorder. This recorder can record a whopping 40 hours of video and about 910 hours of audio.

This article gives you the basics on what to look for when shopping for a surveillance camera system for either personal or business use. In a future article, we will discuss detailed directions on how to connect and set up the most common types of surveillance camera systems.

Helpful Tips For Buying A Digital Camera

People who are technologically challenged might find purchasing a digital camera quite a difficult thing to do. There are hundreds of cameras available. Often buyers have no clue where to begin. However, Consumer Reports might be quite helpful if you are considering buying a digital camera. Purchasing one should not be an unpleasant thing, it should be a nice experience provided you conduct a little bit of research.

I had to purchase a good camera for my family a few years ago but I didn't bother to research all the options out there. I didn't consider purchasing a digital camera a big deal. I didn't want something too expensive but I also didn't want to get a piece of junk. Thus, I was looking for a camera which was neither cheap, nor expensive. You should trust me that this is not the right way to buy a digital camera.

The camera I bought back then was not made by a well-known company and I found it in a discount bargain store. Generally speaking, buying technological items from a store selling groceries, as well is a bad idea. Actually the one rule that should always keep is to never buy a digital camera from such places.

The moment I tried to use my camera for the first time I got disappointed. It was difficult to use, so it took me a few hours to master but unfortunately, it was not what I expected. What was probably the greatest disadvantage of this digital camera in particular was that there was a four second delay between shots.

Moreover, there was a two second delay when taking the initial pictures. That made it really difficult to know when the button should be pressed. You know how brief a baby smile could be. Last but not least, the anti-red-eye flash appeared a second before the actual flash.

This camera was not easy to use. Even adults found it difficult to pose for pictures with this equipment. The second time I wanted to get a digital camera I knew what I was looking for, a camera that takes quick shots. I wanted a device that actually functions like a real camera.

After considering many deals, my husband and I got an issue of Consumer Reports which gave information about the best options for anyone in search of the perfect digital camera. We decided that the "Best Buy" pick was suitable for our needs. Ever since I got this unpleasant experience with the camera I once purchased, I have been doing a little research before making whatever major technological items.

Purchasing a Digital Camera

Purchasing a Digital Camera

The term "Digital Photography" can be used to cover both still and video photography, when purchasing either of these technologies the same criteria can be used to make sure that you acquire the correct piece of equipment for your needs.

There are many things to consider when buying either a digital camera. The first thing to do is to figure out what your budget is. Camera prices range from a few pounds for low-end models to thousands for the high-end models for professional use. Decide how much money you would like to spend and what the usage of the camera will be. Try to answer questions such as: Are you going to take family photos, shoot landscape photos, travel a lot with the camera, use a lot of flash photography, Speed of aperture for the faster action shot is also important with the stills camera. The same applies for camcorders, are you looking for camcorder to work in bright sunny conditions or darker cloudy conditions such as using on a skiing trip

Once you have decided on the budget and the usage look for potential cameras. If you have decided to look for your camera on the web you may want to make use of a more specific search engine phrase such as" Sony digital camera" or "digital photo printing services", in doing this your results are going to be highly targeted to your particular digital camera needs.

If you create a table you can list the cost and features of each of the different types of camera or camcorder, this will help you to narrow down your search for the correct camera to fit your needs.

The features you should be looking to add to your list should be the following:

New cameras are packed with an ever increasing number of mega pixels. Is more mega pixels better? A quick answer would be yes - but a better answer would be "it really depends". More mega pixels are important if you are going to print photos (especially enlargements) or if you are going to zoom in and crop fine details out of big photos. If you plan to watch your photos on your computer screen and maybe just print a few 4X6 prints every now and then than 2 mega pixels is more than enough (yes... just 2). Most screen resolutions are about 1024X768 so even when viewing the photo in full screen mode you can only view 1024X768 which is less than 1 mega pixels. A 2 mega pixels, 4X6 photo print will have a DPI higher than 300 which is more than enough for a high quality print. If you plan to print photo enlargements then a rule of thumb is to be able to print at least 300DPI resolution. The following is a table for different print sizes and the mega pixels needed for such print quality:
page 4X6 2MP
page 5X7 3MP
page 8X10 7MP
page 11X14 14MP
page 16X20 28MP
page 20X30 54MP
Unless you budget is infinite when you buy a camera with more mega pixels you make a compromise between mega pixels and other features. For example is it better to spend money on more mega pixels or on better lenses? Or maybe on an external flash? It all depends on how you will use your camera. Evaluate your usage and decide what is more important to you.

In some situations it is very useful to have a good zoom capability. For example when you take a portrait photo you want to make sure the object's face fills the photo frame while when you take a group photo you want to make sure everybody is in the photo frame.

Some manufacturers state the camera's zoom figure without specifying if it is optical or digital. Optical zoom works by physically moving the camera's lenses and changing the focal length. By changing the focal length you can make objects appear bigger and fit the full photo frame. Digital zoom works by applying built-in software in the camera to define a portion of the photo which you are interested in. Once chosen the software crops the rest of the photo and enlarges the area you chose to fit the complete photo frame. The downside of this digital process is that the enlarged photo quality is lower than the original photo's. The conclusion is that optical zoom is superior to digital zoom so when you compare different camera's zoom always compare their optical zoom capabilities. You can totally ignore the digital zoom figures.

With ever growing storage capacities digital cameras today can hold hundreds and sometimes thousands of photos on a single media. You can always have a few more in your pocket and changing is very fast. The result is that a digital camera has practically infinite capacity. You can shoot as many photos as you want and at the end of the day just dump them on your computer disk. There is no time lost changing film and there are no photo opportunities lost due to lack of film or reserving film for later.

Advances such as the internet can make us neglect the many different digital photography resources that are currently freely available to us such as the town book shop or town library which can often be an obvious place to obtain guidance about digital camera products, you should certainly make use of these kinds of havens of great digital camera data as suitable digital camera product information may very often be hard to find

How To Shop For A Digital Camera On The Internet

There has been a technological revolution over the last twenty years. From the spread of the pc to the rise of CDs, DVDs and MRP3 players; how we approach and record our images of the world is changing. One of the most significant developments to have appeared on the market has been the digital camera. Almost everyone who owns a pc also owns a digital camera. The beauty of these is that you can view your picture as it will be and then decide whether to snap or not-once snapped you can see the picture again. Pictures taken with a digital camera can be uploaded to a computer and then printed out on the special paper that you can buy; alternatively you can put them on disc and take them to a professional processor.

The digital camera is uniquely different from what went before. Prior to the invention of the digital camera, even the most high tech cameras depended on mechanical and chemical processes. Digital cameras work differently because they have an inbuilt computer that records images electronically. Basically they are filmless cameras. When they first came out digital cameras were beyond most people's budgets-as they have become more popular, the price has dropped to the point where they are as affordable and flexible as similarly priced film cameras. The amount of images you are able to store depends on the amount of memory you have-storage can be anything from 16mb to 256mb. The memory size also has an effect on the resolution of the pictures you are taking-memory cards are removable however, and can be replaced with something that has more storage capacity.

There are three main styles or shape of digital camera, the first is small enough to fit into a pocket, it is the most sort after style and also quite expensive. Next you have the standard size, which is bigger and able to do all the things that the point and shoot camera will do. This model is good value for money. Finally there is the digital SLR which produces the best photographs. It is an extremely flexible model and you can switch lenses with this one, but these enhanced features come with a corresponding price tag.

Other information you should be interested in when buying a digital camera is pixels-briefly put, pixels are the dots that go to make up a picture. These pixels are measured in thousands of such dots; called megapixels. The more megapixels you have the sharper your pictures will be and the bigger the price tag on the camera. If all you want to do is produce 4x6 photos and maybe email some images then a 4 megapixel camera should be adequate for your needs. You need to bear in mind however, that the quality of the images you produce depends on three things; the speed of your computer, the type of software that the camera works with, and the quality of your laser or inkjet printer.

The final thing that you might want to bear in mind is optical zoom-this lets you magnify what you are shooting and gives you more control over framing the shot. The one most recommended for flexibility is the 3x optical zoom, don't let vendors confuse you with digital zoom-it is not a viable consideration. With this information at your fingertips you should have no trouble in purchasing you first digital camera.

Printing from Your Digital Camera - The Dos and Don'ts to Preserve Photos

Since the introduction of the digital camera, consumers have hailed the convenience and immediacy of their work. Snapping pictures and being able to view them on the camera to determine if a retake is needed, sharing them online within moments of recording images, and producing prints at home without the time involved in filling an entire roll of film, transporting them to the photo lab, and awaiting their development are among the best loved features of the digital camera.

Beyond the convenience of a such a camera however, the question of how well images printed at home would endure the years has been a significant concern. In the early years, the quality of the various types of printers, inks, and paper were much less reliable than the photographic processes used in a photo lab. Many years have passed however and progress has been made in developing more durable materials. Although only time will tell, in today's market, some printer manufacturers tout a life span of 75 to 100 years or longer for prints produced by their printers and materials.

In addition to the ongoing advancements in printer technology and paper/ink quality, home photographers can certainly do much to assure that their grandchildren will be able to enjoy the images that they record on their digital camera today through proper handling.

Materials

Do: Use of a high quality printer designed for printing the photos from a digital camera is recommended of course but quality ink and paper which complement each other helps to assure the longevity of the print that is produced. The best way to assure that the printer, paper, and ink used will work well together is to purchase them from the same manufacturer. The paper selected should be coated and designated specifically for printing photographs.

Don't: Use of some materials in framing, mounting, or matting pictures speeds the demise of the print and should be avoided. For optimum longevity, materials should pass ISO standards for being acid and lignin-free. Corrugated cardboard and PVC coverings are materials to be avoided when working with prints.

Handling

Do: When producing prints at home it is critical to assure that they dry before handling them. They may dry to the touch almost instantly, but it is advisable to allow them several hours before handling, framing, or storing them.

Don't: Prints created at home are particularly susceptible to damage from the oils in a person's skin as well as the abrasion created by touching or brushing against them, therefore minimizing how much these prints are touched can help to reduce degradation of the image.

Display

Light, humidity, contaminants in the air, and exposure to water are other factors that can significantly damage prints. Displaying unprotected, uncovered prints potentially exposes them to all of these factors which can result in an early demise for the images so lovingly captured by the camera.

Do: For display purposes it is wise to place prints in a frame with an anti-UV glass cover or to insert them into a clear protector; although polyvinyl chloride is not a recommended material.

Don't: Displaying prints where they will be directly in the sunlight promotes premature fading and placing them in environments with higher heat and humidity such as in a kitchen or bath can promote fading, blurring, and yellowing.

Storage

Do: Placing prints in an album offers a convenient method of properly storing them as well as labeling and displaying them for future enjoyment. Ideally, the album used should be acid and lignin-free, offer non-PVC page protection, and allow the user to attach prints via corners versus an adhesive.

Don't: Because of the negative effects of light, heat, humidity, and exposure to pollution and water, storage in both attics where temperatures can soar and in basements where humidity and the risk of exposure to water is greater is not recommended. Closets are a better option as it is best to store prints in a cool, dry, dark area.

The conveniences offered by a digital camera are ideal for those wanting to enjoy and share a moment via pictures. For those hoping to use their camera to provide a more lasting record, recent advancements in printing technology would seem to offer the potential of sharing memories captured today with future generations. Home photographers will simply need to use an appropriate camera, printing materials, and assure they follow a few rules when handling their prints to assure they provide a lasting impression.
