Different Uses of a Wide Angle Security Camera
Just about every small business and private home could benefit from surveillance technology. When the idea of using cameras to provide security for someone’s property first evolved, the gadgets’ use were limited to big industries, corporations and the military or government. However, even now the difference is often noted: while small homes tend to use portable and small security cameras, a wide angle security camera is still most often used only in big businesses and the like.
Military and Government Uses
One of the most popular uses for the wide angle security camera is security and information gathering in the military and various branches of the government. Guarding important people mean that securities cameras should be able to give a wide range of sight not offered by ordinary security cameras. You can almost always see these types of security cameras on large, open fields and paths leading to important government and military offices.
Law Enforcement Applications
This type of security camera is also popular with law enforcement. Nowadays, you can see them on top of traffic lights and busy intersections as a way for police to check for traffic violators and to help radio in the location of someone the police is chasing. The camera used by police is equipped with a video capture feature so they could take pictures of people who are running through red lights and speeding in areas where no patrolmen are around. This technology has also helped police determine who is responsible for road accidents.
Industrial Uses
Industrial buildings, especially those in the manufacturing, chemical and raw materials sector are often required to have wide angle security cameras in their premises. These buildings are considered to be at risk for fires, chemical contamination and explosions. Wide these cameras, supervisors and guards can oversee the work done to make sure nobody is out of line. During times when an accident occurs, these cameras are also helpful in locating the cause of it.
Commercial Uses
Even if it is not mandated by law, other establishments like fast food, malls, and other large businesses make use of wide angle cameras to keep their buildings safe. Most of these buildings have a separate room filled with several monitors, each corresponding to a different camera. These have been proved to be effective against thieves, vandals and gangs who like to harass customers.
For Private Homes
Even homeowners who have a huge estate have turned to wide angle security cameras for their needs. Most of these homeowners include estates with ranches, farmlands, and those who simply have a lot of area to cover.…
Swann Wireless Security Camera
Any Swann wireless security camera from their line of very popular outdoor security cameras would make a great additional to any home security system. For most basic security needs, a Swann wireless security camera is the best entry level wireless security camera that transmits at 2.4GHz and is easy enough for almost any to set up themselves. It offers good video quality with a 1/3 inch CMOS image sensor providing a resolution of 380 TV lines.
At night it switches into a night vision camera that is good for 26 feet or 8 meters of viewing range. The wireless transmission at 2.4GHz offers a range of about 165 feet or 50 meters of unobstructed wireless signal. The camera automatically switches from color to black and white for day/night use and the metal casing protects the camera from weather conditions. There is a microphone included to record audio with the video which most security cameras do not offer.
This product is truly as close to plug-and-play as you will get. Simply mount the camera at its desired location, connect the receiver to a TV or VCR, power everything on and it is ready to go. The entire system was built to be expandable up to four cameras so it is easy to add cameras in the future making it perfect for larger homes or businesses. Individual cameras are sold separately for those who already have a receiver unit and just to add more cameras into their system.
One of the greatest features of this camera is the compact design. It is small making it easily hidden in the corner of under an overhang of the roof at home. A hidden wireless outdoor security camera can be very effective since no one suspects they are being watched allowing you to catch them in the act. Currently the wireless outdoor camera operates on a single 9V battery which is not bad at all.
What makes this product truly versatile is the additional feature of being night vision capable. A night vision security camera can cost a lot of money but with the Swann wireless security camera, infrared LEDs are built in for recording at night. Mounting is a cinch with screws to connect the stand to whatever surface your decide works best.
One aspect to watch carefully for is interference with an existing Wi-Fi connection set up in your home. Most buyers will want a newer model that takes care of such problems since they are readily available now and most homes will have a Wi-Fi network setup sooner rather than later. For example, the Swann’s ADW-300 Digital Wireless Camera & Receiver will not interfere with existing Wi-Fi connections.
Outdoor Security Camera W/ Night Vision
Practical and commercially available night vision security cameras use Image Enhancement or Image Intensification technology. It is built with a special lens that can detect light at a slightly higher frequency than thermal-infrared. When light hits an object, it emits a thermal frequency which is how true thermal-infrared works. Thermal-infrared is great for complete darkness while Image Enhancement picks up more reflective higher frequency than thermal-infrared. In short, light photons are converted to electrodes, amplified, and converted back to photons to display a visible image on your camera screen or monitor.
The details that your night vision camera picks up can be enhanced with what is known as infrared illumination or infrared LEDs. It’s the technique of flooding an area with reflective infrared light. Very similar to shinning a light so you can see better, it shines infrared light so the camera can ‘see’ better. In fact, despite popular perception of blurry red-green blobs, the image quality is actually very detailed and clear. The only compromise when you choose to use a night vision security camera is color. It will show up as shades of green. Most devices were manufactured this way because our eyes can detect more shades of green than any other phosphorus color.
For commercial use, the range of outdoor night vision cameras will serve well. In optimal conditions you can typically get anywhere from 30 to 300 meters depending on the quality of the camera.
When picking out a night vision security camera, you will notice two main specs to focus on. The Lux rating, also known as the minimum illumination rating, is the minimum amount of light needed for the camera to pick up something. The closer the camera’s Lux rating is to zero, the less light the camera needs to ‘see’. Some security cameras have a minimum illuminations rating of 0 meaning it can perform just fine in complete darkness. There are color day/night cameras that switch to black and white or phosphorus green when lighting conditions hits the minimum illumination requirement.
There is also this notion of generations of night vision cameras. This refers to the advancement of the technology used for detection. Gen 0 was used about fifty years ago and was nothing more than an infrared spotlight with a receiver. The technology advanced through Gen 1, 2, 3, and 4. Don’t go buying a cheap Gen 1 camera. With today’s technology the performance is going to be crap.
Power options are similar to any other outdoor security camera: adapters for wall socket, battery pack options, and other creative power source adaptations you electrocuted yourself to invent.
