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.

Home Monitoring Over the Internet

Friday, June 11th, 2010

The use of home monitoring over the internet may be your solution to keeping track of things at home while away from home. There are several types of home monitoring over the internet that are being used today including nanny cams, baby cams, nursery cams, pet cams, and security cams. Modern technology has yielded home security cameras that offer a multitude of features and can be networked over the internet while remaining affordably priced.

Home monitoring over the internet can be accomplished in two basic ways. The first is to use an IP camera and the second is to use an older standard analog camera with a hybrid DVR and/or video server. Let’s take a look at a basic home security system first and then see how the two methods above are applied.

A basic home analog security system consists of from one to several analog Closed Circuit Television (CCTV) cameras, a processing unit with recorder, and a monitor. A basic home digital video security system consists of one to several digital video cameras, a processor, a monitor, and a Digital Video Recorder or DVR.

An analog system can be converted to home monitoring over the internet by using either a hybrid DVR or a video server. A hybrid DVR “digitizes” the analog video sent by the CCTV cameras on a “capture” board. This is a specific integrated circuit that is dedicated to only capturing analog video signals and transferring them into digital video signals. Once the analog video is converted to digital, it is transferred into a digital video file. However, digital video files can be extremely large so software or a portion of the hardware of the capture board employs a COmpression/DECompression or CODEC utility to reduce the size of the file while maintaining high video quality and clarity.

An analog to digital video server does the same digitizing converting process but does not record the file. Instead it sends the file along the network where it can be handled at another location. The key is that once the analog signal is digitized, using the proper software or hardware equipment it can be manipulated and transmitted over the internet, using the internet as the virtual network for the cameras.

Home monitoring over the internet using modern IP cameras can eliminate a lot of excessive work that is required in converting analog video signals or manipulating non-IP ready digital cameras to make them internet accessible. An IP camera is a camera that is already capable of using Internet Protocol (thus the “IP” designation) to transmit its video signals.

Although these cameras can still be connected to monitors or standalone DVRs, they may also be used with a simple broadband internet connection and a personal computer. The personal computer is usually able to use an internet browser or a software program provided by the camera manufacturer to monitor and record the video transmissions.

Therefore, home monitoring over the internet can be accomplished using the new advanced IP camera technology or by converting the more traditional analog CCTV video to digital and then preparing it for and sending it by the internet. In both cases, once the video transmission is internet ready and is streamed across the internet, you can view your home security system anywhere the internet is accessible. Or if you prefer to have your system “tied” in with a residential security alarm and monitoring system, internet monitoring makes this possible too. n addition, as technology continues to advance it has now made it possible to perform home monitoring over the internet even on a 3G or 4G smartphone, and all of this can be done at affordable “residential” prices.
