Spring Airsoft Rifles

Thursday, November 11th, 2010

Spring airsoft rifles are a safe yet realistic alternative to the real rifles they are modeled after, however spring airsoft rifles look and feel like the real thing. Spring airsoft rifles shoot 6 mm plastic BBs or paintballs instead of real ammunition or metal BBs making them an excellent alternative to the real rifle for use in simulations or training and for sport and leisure gaming.

Airsoft is a generic term used to describe any weapon that shoots plastic 6 mm round pellets or BBs. This ammunition is larger than conventional steel, copper, or other metal BBs which normally have a caliber of 4.5 mm. Typically, the BBs weigh .20 grams or heavier and are normally sold based on the weight of the pellet. In addition, airsoft weapons may be constructed to use a variety of propellant methods for shooting the plastic pellet including electric gear driven power boxes, gas, and spring action.

Most high quality spring airsoft rifles are exact replicas of their real counterparts. The gun body is even constructed of full jacketed metal and weighs the same as the original. This provides the most realistic training available while maintaining a much safer disposition to the weapon. In addition, realistic rifle accessories such as magnifying and non magnifying scopes and laser sights are also available maintaining the most realistic mock-up possible.

Airsoft guns are normally categorized based on whether they are handguns or rifles. Rifles are further categorized into three basic groups based on how the projectile is propelled, gas, electric, and spring. Although every model has its own unique list of specifications, as a general rule the muzzle velocity of a spring airsoft rifle is between an electric gear box driven model and a gas model.

Typical velocities for automatic electric gear box driven rifles range from approximately 200 to 380 Feet Per Second (FPS), while gas powered rifles average approximately 450 to 500 FPS (again, this is just an average as each model is different). Spring airsoft rifles typically range from about 350 to 450 FPS. Depending on the model, the shooting range of an airsoft spring rifle ranges from 70 – 250 feet, with most shotgun models at the lower end of the range and most sniper type rifles at the top.

Gas powered airsoft rifles may use CO2, Green Gas, or even propane to propel the plastic BBs out of the rifle. Spring airsoft rifles are powered by the potential energy stored in a spring by the user “coking back” the spring for each shot. The spring is attached to an airtight piston that is housed within a cylinder. When the trigger is pressed, the spring instantly transfers all of its potential energy into kinetic energy by releasing the piston which is pushed forward at a high rate of speed inside the cylinder. This causes the air within the cylinder to become high compressed, forcing the plastic BB forward out the barrel.

Some spring airsoft rifle models offer additional spring upgrades for purchase. These spring upgrades offer a higher tension spring which can store and release more energy. This in turn creates a projectile with a faster muzzle velocity (FPS) and a potentially longer distance range.

There are basically three types of spring airsoft rifles. Single shot rifles shoot single shots of BBs and simulate many of their real counterparts. Shotguns look and feel like their real counterparts, however instead of firing a spread of small BBs or “shot” like a real shotgun, they usually are made to fire one plastic BB. Sniper rifles, as their name implies, simulate the look and feel of their real high-powered counterparts.

Spring airsoft rifles offer an economical, safe alternative to real rifles. They allow the user to become comfortable with carrying and using the rifle while offering a safe alternative for target practice, training and simulations. Local, state, and federal law enforcement agencies as well as the U.S. Department of Defense use spring airsoft rifles for training and simulations.

Security Cameras for In Home Use

Wednesday, August 4th, 2010

There are several types of security cameras for in home use. In fact, just about any security camera can be used for residential purposes although there are cameras that are more suited for in home use than others. Security camera technology has advanced so much recently that the versatility of security cameras for in home use is almost limitless.

Every home is different; the number of rooms in the home, the perimeter area that surrounds the home and the size of the home’s yard, the entrances and exits, number of windows, especially those on the ground floor – all vary from house to house. As every home’s design is different, so are the uses and needs for the security cameras for that home.

The most effective method to determine what security cameras for in home use are best for you is to evaluate your home design and your security desires and needs. After determining what you need to provide and the level of security and monitoring you desire, you can more easily begin the process of shopping for specific cameras that will satisfy those requirements.

Still, as stated earlier, there are security cameras for in home use that are more suited for this application than others. For an obvious example, an explosion proof camera or housing would be a ridiculous and unnecessary expense for in home use. However Security Camera King offers several different indoor security cameras that are perfect for in home use.

One way to narrow down your camera choice is to determine if you will be able to run the video transmission cable from each camera to the processor/DVR or Digital Video Recorder or if you would prefer a wireless camera instead. Cabling is the least expensive and the most common option for connecting the digital video camera to the DVR.

However, if installing the RG59 coaxial cable would be troubling for you, or if the cable would seem unsightly, or for any other reason the cable would not be right for you, wireless cameras would be the appropriate selection. Wireless cameras still require electrical power supply, normally in the form of a small wire run to the camera from a plug-in transformer or power distribution box. There are some wireless cameras that use rechargeable batteries as well.

Wireless cameras make use of radio technology to broadcast their video data to a corresponding receiver which then transfers the signal to the DVR. So a receiver is also needed if you choose the wireless camera option. Most receivers can handle up to four cameras at one time so if your system requires more than four cameras additional receivers (or a receiver that can handle more than four cameras) will be needed.

Regardless of whether you use cable or wireless technology, there are several different security cameras for in home use based on appearance, mounting design, and function. There are basically three types of cameras based on appearance. They are the box, bullet, and dome types, with each name representing a description of the appearance of the camera.

Each type has its own benefits and deficits. The box camera is probably the most common style of video camera but can also be somewhat obtrusive mounted on a room wall. The bullet type is also popular, but this type of camera usually lends itself to weatherproofing and infrared technology geared toward the outdoors. So if the box and bullet types are not appropriate for your application, then the dome type camera would probably be the best choice.

Dome cameras are fairly low-profile cameras with many available as a flush mount. Flush mounted dome cameras are installed in the wall or ceiling with only the “bubble” cover extending away from the surface. Security Camera King offers several different types of indoor dome cameras based on use and resolution display. That includes total darkness capable night vision infrared dome cameras as well.

Another category of security cameras for in home use include the hidden or disguised camera types. The cameras are embedded inside clocks, thermostats, and other everyday items to disguise their appearance.

Wireless Security Cameras For Home Protection

Monday, June 21st, 2010

If you are looking for a state-of-the-art security system for your house, try using wireless security cameras for homes. Wireless security cameras for homes come in many different varieties making them incredibly versatile in application, and thanks to modern technology the prices are affordable too.

Not long ago, security camera systems used Closed Circuit Television cameras that sent an analog video signal to a processor/recorder that made the signal useable for viewing and recorded it on video tape. Tape cartridges were either replaced when they were full or special loop cartridges would repeat recording new video over older footage.

Digital video cameras and other modern technology has drastically changed surveillance cameras and their applications and made it possible to utilize wireless security cameras for homes. Video tape is no longer needed because the newest cameras are digital video cameras. Instead of sending an analog signal, these cameras send digital video signals which can be stored on digital hard drives or Digital Video Recorders (DVR). These cameras have also made it possible to have wireless security cameras for homes.

The major difference between wireless security cameras for homes and cameras that are “wired” is that the wireless camera has its own on-board transmitter and antenna. The wireless camera transmits its digital video signal via the antenna to a receiver, which is normally located near the monitor and/or DVR. Not only has using digital video made this possible but the advanced technology behind the 2.4 and 5.8 GHz radio band has permitted ranges for these cameras up to two miles.

Most wireless security cameras for homes are not entirely without wires. Although they transmit their video signal via radio waves, they still must receive some sort of electrical power supply. Generally this power supply is in the form of a thin wire that carries low voltage DC current from an AC power adaptor that is plugged in nearby or from a power distribution box that performs the same function for many cameras. However, eliminating the coaxial transmission wire means that it is not necessary to cable each camera to the processor/DVR unit. Basically, installing a wireless camera is as easy as mounting the camera and plugging it into the power source.

Wireless security cameras for home can be indoor or outdoor types. Outdoor models are much like indoor models except they are enclosed in a protective cover or case. Outdoor cameras are usually rated using an International Electrical code standard. The rating, called an Ingress Protection or IP code, helps to define how much protection the case provides. Generally, most outdoor cameras are rated IP66 or IP67. Both ratings indicate the camera is dust tight; IP66 means it can withstand powerful jets of water and IP67 means it can be submerged in up to one meter of water without damaging the camera.

Wireless security cameras for home produce high quality color digital video. These cameras contain a sensor chip that transfers the light image focused on it from the lens into an electrical signal. One of two sensors is used; either a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS.

These sensor chips can be so sensitive that they can produce high quality color video images in very low visible light conditions. Cameras that have these special sensitive chips are call day/night vision cameras and are often rated as to the degree of light that needs to be present to produce an image. The rating used is “lux” and cameras can be as sensitive as .002 lux; this light intensity rating is equivalent to the amount of visible light seen in a moonless clear night sky.

Other wireless security cameras for home may be night vision infrared cameras. These cameras can detect infrared (IR) illumination that is invisible to the human eye. The camera normally comes with several IR Light Emitting Diodes or LEDs that provide IR light for the camera. Since the light emitted is in the near infrared spectrum our eyes cannot detect it. These cameras are excellent for use as baby monitors.

Other options available for these cameras include the ability to record audio, Pan-Tilt-Zoom (PTZ), and cameras that use rechargeable batteries instead of a power supply.

Today’s innovative technology has presented us with wireless security cameras for home for just about any purpose or environment. Wireless security cameras for home are as cinch to install and are reasonably priced as well.
