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.

Nikon Coolpix S3000 12 MP Digital Camera with 4x Optical Vibration Reduction
A digital camera might look like a film camera but they are actually quite different. Both freeze light to make a photograph. Film cameras do this chemically using film. Digital cameras use a light sensitive CCD or CMOS silicon chip to convert light and digital information into pixels.
Pixels are the tiniest areas of light that your digital camera can recognize and change into information. The greater amount of pixels the more detail and higher the resolution the photograph. A low resolution color printout of tree will show that it is green but in a high resolution photograph the leaves and texture of the bark will be more sharply defined.
With digital photographs your have the ability to use software like Adobe Photoshop Deluxe and Microsoft Picture to edit photos and make corrections.
Choosing Your Camera
Important considerations when choosing a digital camera are: What do you want the camera to do? What features do you require? How much do you wish to spend on your camera?
There are professional high end cameras that cost thousands of dollars, cheap throwaway cameras and a huge selection of mid-level cameras available to choose from.
Will you be photographing images for the internet and for email? Will your photos be printed? For regular print size snapshots and web photos a one to two megapixel camera will do. In fact for the web a lower megapixel would be better as higher resolution photos are slow to download.
Do you want a point-and-click camera? Are you someone who just wants to get the picture taken with the least amount of bother. Do you want a camera that does everything automatically and you simply have to press a button? Or, are you someone who would rather figure out the best settings for your camera and make the adjustments manually? It's always best to find a camera that suits your purpose, need and ability.
High or Low Resolution
High end, high resolution cameras are good for photographs that are to be printed. The greater the number of pixels the higher the resolution. High resolution does not make sense on the web as the extra resolution does not make images appear any sharper. Also, high resolution photos are slow to download on the web.
To print your photographs you will need a good quality color printer. If photos are to be printed, high resolution does make a difference depending how large you want the picture to be. High resolution will give a large print better definition. High resolution cameras cost more. Expect to pay more for high resolution. You also need to check that your printer can handle high resolution prints.
Lenses
Low-end digital cameras have fixed focus lenses made of plastic. With these lenses everything is focused and you don't need to make a decision what to focus on.
Variable focused lenses are made of glass or high quality plastic. These lenses focus on whatever object you are trying to capture in a photograph.
Most mid-range digital cameras come with auto focus and manual focus built in. Auto focus is for point-and-click photos of whatever is in the middle of the frame. Or, by turning the ring over the lens, you can manually focus the camera. These cameras allow users to switch between auto and manual focus.
Zoom Lenses
Digital cameras have optical zoom and digital zoom lenses. Optical zoom costs more, give a better quality picture, and works the same way as on non-digital cameras with lens adjustments. A digital zoom comes about when the camera makes calculations to manipulates the pixels. Digital zoom gives a less sharp image. Some cameras include both optical and digital zoom.
View Finder
The view finder is what you look through to see what you are photographing. The view finder on both digital and regular film cameras will approximate the picture your lens is viewing. Digital cameras will also come with an LCD display that you can use to check your photographs and decide weather or not to keep them.
Lighting
When it comes to lighting you might not want the camera to make the decision automatically for you. On an auto setting you camera might not make the best lighting choice given the location and environment. At times like this you can appreciate being able to switch between manual and automatic settings.
Digital cameras allow you to test exposure and view a picture on LCD prior to pressing the button fully and committing to a photograph.
Flash
There will be a built in flash that comes with your digital camera. In addition, the better cameras have a location for a flash attachment. This is a good option for producing better quality photographs.
Connecting to Your Computer
You will need a PC USB cable, or for Mac's - Firewire or Mac USB cable, to connect to your computer. You will also need a cable adapter for your camera's CF (Compact Flash) or SM (Smart Media) card .
The CF or SM cards are removable high capacity storage cards for your photos. Your camera will use one type of card or the other. Not both. Check to see which type of storage card your camera uses.
USB connections are fast and easy to set up. Older cameras connect through a serial port. USB is faster and does not require that the computer be rebooted before it recognizes the camera.
Batteries and AC Adapters
Digital cameras often come with rechargeable batteries. It is best to have two sets of batteries. One set to use while the other is recharging. AC adapters make it easy to plug into an electrical outlet when you are near by one.
Main Drawback of Digital Camera
The main drawback of digital cameras is shutter lag delays when the camera delays responding after you squeeze the button. It is possible you may miss the moment when photographing moving objects due to shutter lag. Some of the newer cameras are beginning to address the problem.
Select a camera that does what you want it to do, has features you will use and is priced in the range you want to pay. This will be the right camera for you. If your experience is limited and you do not want to take a lot of time learning how to use the camera, go with a point-and-shoot camera. Something without too many features. If you are a camera enthusiast who wants to do more with your camera or is willing to take the time to learn how to use the feature then, by all means go all out.
