Just a comment on best type camera sensor. You will notice WDR - wide dynamic range spec on some cameras. That is more than likely due to the Pixim sensor.
Pixim has put a seperate AGC circuit on EACH pixel giving the camera a 120db S/N spec versus the usual 50 or 60db. That means extreme sensitivity or attenuation on pixels right next to each other. This cuts the blooming or saturation of the sensor and on dark areas brings up the gain as needed to see the image. This is a major difference with WDR versus the rest of lower performing cameras. Resolution on this WDR cameras by different manufacturers is 720 x 480 NTSC or 720 x 576 PAL so you get best max resolution for your analog signal anything less, is just less...performance. You can get a bullet camera arrangement along with 820 or 940nm IR capability. We supply these with the wireless analog and COFDM digital wireless systems we manufacture in the US, that can go 35 miles with right antennas/situation and even provide battery / voltage status from the transmitter and PTZ with add on two way RS232 data units.

Outdoor Wireless Security Cameras – All You Need to Know
A little research can go a long way in ensuring that the right equipment is purchased at affordable prices. Most security equipments have a number of options available in the market and improper understanding can either lead to a bad purchase or an unnecessary purchase. Let us understand the basics of outdoor wireless security cameras that will help you in buying the right outdoor camera for your security system.
Different Outdoor Wireless Security Cameras
Analog and Digital Cameras
These are the time-tested devices that have been used since a long time in different security systems. They can be connected to the video surveillance systems through wires. These cameras are less expensive as compared to their digital counterparts but they are difficult to install.
Power
You can use wired devices that can be powered by connecting their wires to the central power unit. A better option is the wireless camera that does not need wiring but needs to be connected to power outlets. In case you are installing cameras where power outlets are not available and cannot be made available, then consider using wireless cameras that run on batteries. These cameras can be easily installed at any place but need to be constantly monitored for battery changes.
Lux Number
Outdoor Cameras are exposed to different lighting conditions throughout the day and these conditions also vary in different weathers. Use cameras with low Lux number which signifies that the cameras can cope with dim lighting conditions. You should also invest in night vision cameras that use infrared technology to capture images even in pitch dark conditions.
Weather Proofing
Cameras are sensitive electronic equipments and hence, they need to be protected from the vagaries of nature. While investing in an expensive camera make sure that you also buy a weather proof casing to guard your camera from excessive heat and moisture. In very cold regions, cameras with insulated casings should be purchased. For hot weather conditions, casing with exhausts will come handy.
Protection from Vandalism
It is important to protect your equipment from vandalism. Buy an outdoor camera with sturdy material. Use a casing that can protect any on-the-spur attack on the camera. You can also buy dome-shaped cameras and casing that gel well with the surroundings and make these camera less visible, thereby, protecting them from any danger.
Ideal Transmissions
Using wireless devices has a drawback that there signal transmission can be weak. Make sure that you buy equipments that can transmit data over the distance that you require. Factors such as big trees, metals in the walls and bad weather can hinder wireless transmissions. Hence, it always better to invest in good devices with wide transmission range. You can also invest in good quality signal receivers that can capture low quality inputs as well.

Picture and Sound – While selecting a camera, pay special attention to its picture quality. A low screen resolution will not be able to give quality inputs. Audio wireless outdoor security cameras can also be purchased with audio compatible devices.

Protecting Your Outdoor Property with Wireless Security Cameras

You can protect your home better by covering the outside areas of your property. This will ensure that intruders are stopped at the periphery itself and they do not come close to the actual building – whether it is a home or office. You can use the alerts sent by outdoor security systems to take timely actions. For outdoor use, wireless systems are the best option. Let us look at one of the most effective security devices for outdoors – wireless security cameras.
Wireless security cameras offer a very advanced level of security. However, outdoor and indoor security requirements are different and therefore, the cameras installed inside your home might not work for outdoors. It is essential to consider the following points:

Coverage – Do you need to monitor the lawn and garden area or do you want to see only the entrance of your property? Will the garage and driveway need separate cameras? Answering such questions will help you in deciding your requirements. Also decide the angle that you need for surveillance. Wider angles are preferable for outdoor purposes as they cover a large area in one go.
Picture Quality – Low screen resolution cameras are cheaper but the quality of picture is not very high. If you want to have clear pictures, choose cameras with high resolution. There are many cameras that can have both low and high quality resolutions. You can alter the settings as per your requirements.
Wired or Wireless Security Camera – Big obstructions like walls and trees can disrupt signal from your wireless camera whereas wired cameras are difficult to install in remote places. Hence, you might like to choose the camera according to the landscaping of your property.
Features – Do you want to record data at all times or only when motion is detected? Do you want sound recorders as well? A camera that can zoom will be particularly helpful for outdoor security needs. Dwell on such requirements before selecting your camera.
Installation – How will you mount the camera? Will it hang from a place or attached to a wall. You can opt for cameras will multiple installation options like straps, adhesives, etc.
Climate – Outdoor cameras need to tolerate the vagaries of nature. They need to be protected against extreme temperature and moisture conditions. Choose cameras that can fit into the weather conditions at different times in the year. In case the camera is sensitive, you can build enclosures to protect them. Various IP/IK ratings are in there.
Recording – Will you use your camera only for surveillance or do you want to record data as well? In case you need to record data, choose the source that will receive feed from the cameras like TV, computer or VCR and connect your camera to the right source. Additional software will also be required in case of wireless cameras.
Monitoring – If you are selecting a monitoring agency to keep a tab on your property, it is always better to involve them while installing wireless cameras in the outdoor areas. You can also employ a professional from these agencies to do the installation.

Why People Choose Wireless Security Cameras (WCCTV)
With the increase in need for security, the demand for security cameras is also on the rise. There are a variety of cameras available in the market, each made for specific purposes and have their own advantages and disadvantages. One of the never-ending debates is the choice between wired and wireless security cameras. While both have their own pros and cons, wireless cameras have become increasingly popular. Few reasons are:
1.) Wireless cameras can be placed at any location. You do not need to worry about installing wires or electric sockets at difficult to reach locations. All you need is a camera that can function within the signal range of your security system.
2.) You do not need to spend money on installing the new wiring system. In case of wireless security cameras, the expenditure on creating a network of insulated wires to connect the entire system can be saved. This is especially true for building that did not install extra wires at the time of construction.
3.) Wires can also make the presence of a camera obvious. If you looking at installing cameras that should not be noticed by every trespasser, wireless security cameras are the right option for you.
4.) Flexibility and mobility comes with wireless cameras. If you are investing in a security system for a building which you might leave in the future, it is best to invest in wireless security devices. Home owners who have taken their house on rent or lease prefer wireless cameras as they can take the cameras along as and when they move to the nest house.
5.) Save you decor with wireless cameras. You might have spent a lot of time and money in selecting the right decor for your home or office. Installing wires might interfere with the overall theme of your decor. Hence, you can opt for wireless cameras that can be installed with minimal disturbance to the entire property.
6.) If you are an owner of an ancestral property, you would not like to damage the masonry by drilling extra holes and wires into the invaluable structure. Hence, wireless cameras are the best option for you.
7.) Hidden cameras are best in wireless versions. While you can use wired cameras and hide them behind furniture, you need to be very careful in covering them. A wireless camera saves you from this effort. You can hide them anywhere without worrying about their getting discovered. Small toys, cutlery, pens and many other things can be equipped with wireless cameras easily.
8.) If you want to use internet to transfer images to you computer, you can go for wireless cameras. The data transmitted through internet can be accessed from any internet enabled system outside your home or office as well.
9.) If are installing the security system yourself, if is always better to choose wireless cameras as they are the easiest to install.

My name is Rich and I am the business development manager at a US manufacturer of ( Wireless Video/Audio/Data Links ) Avalon RF in the El Cajon / San Diego, CA area. We do both standard analog RF links and the new COFDM digital method of transmission of same NTSC/PAL signal.
COFDM is unique in that it penetrates beyond belief urban area walls and or can go 45 miles+. This new technology is very robust and our receiver is dual receiver, dual antenna for best of received signal. We can remote antennas hundreds of feet no problem utilizing UHF down converters in the panel antennas in 2.4Ghz range and can add up to 6 - 15dbi panel antennas pointing in any direction. Receiver with a simple IP encoder can become a video / stereo audio point for IP as well. The COFDM error checking digital technology is simply stunning. Trenching is very expensive, now you can get into a new frame of mind and take the CC out of CCTV with a wireless link when it makes sense. You can put a full 720 x 480 or 720 x 576 pixel higher resolution NTSC or PAL camera on this system. In 3 months we will have full COFDM in HD. Yes, wireless 720I or 1080I or P etc...at 8 MHz bandwidth and 45 mile range with full HD resolution... think about it. We can also do ( wireless PTZ ), both ways over many miles. Kindly let me know any serious inquires. Rich@avalonrf.com
