Color Cameras for Home Security

Written By:
Tuesday, August 10th, 2010

Security Camera King offers a full line of color cameras for home security. Innovative technological advances have yielded a vast diversity of color digital video cameras with almost unlimited versatility for home security. These cameras now offer features that, not long ago, would have been cost prohibitive or simply unavailable. In addition, today’s color cameras for home security are light weight, easy to install, and simple to use.

There are three basic types of camera based on shape; box, bullet, and dome. Each can be useful as color cameras for home security. Generally speaking, the dome camera is used most often indoors because of its low profile design. Box cameras may also be used indoors but are a bit more conspicuous. Usually, box cameras cannot be used as outdoor cameras unless they are placed inside a protective enclosure. Bullet cameras may be used indoors or outdoors, however these cameras are frequently weatherproofed and designed for use specifically outdoors

A typical home security system consists of the color digital cameras, Digital Video Recorder or DVR, and a monitor. The cameras capture a video image and pass it on to the DVR where it is processed and stored. The monitor is used to view the image in real-time (live) or review older footage.

Digital video color cameras for home security normally use one of two sensors to produce a video image: The Charged Coupled Device or CCD; or the Complimentary Metal Oxide Semi-Conductor or CMOS. When these sensors were first used the CCD was more expensive and produced a higher quality video image but recent technological improvements have put the CMOS on close to, or even par with, the CCD.

When considering purchasing color cameras for home security, it’s important to know a little information about the sensors since they affect how the camera produces an image and even more so, the price. These sensors range in size from about ¼ inch up to 1 inch or so. Generally, the larger the chip the higher the resolution (quality) of the video image produced.

These sensor chips can be built so they are very sensitive to light. Color cameras for home security that contain these types of sensors are called day/night vision cameras and can produce high-quality color images with very little available visible light.

These sensors are also inherently sensitive to certain types of infrared radiation. Using infrared Light Emitting Diodes or LEDs as spotlights, cameras with these sensors can create high quality monochromatic video in total darkness. (The infrared light created by the LEDs is invisible to the human eye.)

There are other options to consider when purchasing color cameras for home security use. Digital video cameras require that a coaxial RG-59 video transmission cable be run from each camera to the DVR. If you will be installing cameras where cabling would be difficult, you may want to consider the wireless camera option. Wireless cameras transmit their video signals via built in transmitters and on-board antennas to a corresponding receiver unit that forwards the signal to the DVR.

Another convenient option is to use IP ready color cameras. IP or Internet Protocol ready cameras for home security systems contain their own server so they can be connected directly to the internet. These cameras can be viewed and controlled using either a simple web browser such as Internet Explorer or their own computer software. You can network your entire home video security system with these cameras using just an internet connection to each camera and can monitor them anywhere there is internet access.

If your home security system requires that your cameras not be obvious, there are several hidden or disguised camera options available as well. These cameras, designed for covert use (they make great nanny cams for example), are designed to be hidden or disguised as other objects. Security Camera King stocks a wide selection of the cameras that appear to be other objects such as smoke detectors, motion detectors, exit signs, sprinkler heads, speakers, wall clocks, telephones, thermostats, clock radios, and many others.

So if you are in the market for digital video color cameras for home security use, check out all that Home Security King has to offer. Not only do we offer color cameras for home security use but we also offer the entire system, whether you need a 4, 8, or 16 channel system.

Security Cameras for In Home Use

Written By:
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 Video Security Systems

Written By:
Tuesday, August 3rd, 2010

Versatility, economic pricing, and Innovative technology are making home video security systems the number one choice for residential security and surveillance. Home video systems are no longer just for the extremely wealthy; and, their abundance of features and options makes them suitable for use in almost every environment and for any need.

Today’s home video security systems are basically component systems. There are several benefits to component systems, but the greatest is the ability to customize each component to suit your needs.

Thanks to great advances in the electronics industry, especially with semiconductors and integrated circuits, cameras can perform a variety of functions that 15 years ago would have been extremely expensive or simply unavailable. Processors and DVRs are becoming exponentially more powerful with each new design.

Typical home video security systems usually have from one to several cameras, a processor/Digital Video Recorder or DVR, and a monitor. The digital video cameras send their digital video signal to the processor/DVR. The processor converts the cameras’ signals into digital video files that can be viewed on the monitor and/or stored on the DVR for later viewing and/or archiving purposes.

Cameras
The cameras used for home video security systems are usually digital video cameras. These cameras produce high quality color video under normal lighting conditions. Cameras can be purchased with extremely high resolutions that create extremely high quality video.

Cameras are also available for special lighting conditions. There are cameras that can produce high quality video under conditions of very little visible light or cameras that can produce high quality monochromatic or black and white video under conditions of total darkness. These “low light condition cameras” may be useful for perimeter coverage of the home and yard and other outdoor applications.

Night vision infrared cameras are useful for monitoring areas outside or inside the house that are normally not illuminated at night. They are also great for use as a baby monitor camera, nanny cam, and monitor for rooms that are normally not lit such as closets, storage areas, garages, stairwells, etc. These cameras use infrared Light Emitting Diodes or LEDs to illuminate their target area with infrared light. This “light” is invisible to the human eye but can be seen with the camera’s special sensor.

Another useful camera option is a camera with a motion detector. These cameras have small infrared sensors that detect a change in infrared radiation from moving objects. These motion detectors are connected to a relay that can turn the cameras on and off. These can be used to record video only when motion is detected saving DVR storage space. They can also be used to alert you when someone or something is present.

Other available options for cameras include:
• Indoor or Outdoor use
• Wireless transmission technology
• Audio recording in addition to video
• Pan-Tilt-Zoom or PTZ functions that allow the camera’s position or field of view to change
• Hidden or disguised cameras (often used as nanny cams)
• IP or Internet Protocol ready cameras can transmit their images over the internet to anywhere in the world there is internet access

Processor/DVRs
This is the heart and brains of the system. It normally contains the utility that compresses the digital video files to make them smaller. There are many different options for different types of compression utilities. DVRs can also be purchased in a variety of storage capacity options. In addition, other “peripheral” items such as CD, DVD, or Flash card writers can be added to the units.

There are also home video security systems that eliminate the need for a processor/DVR and monitor. These systems utilize your personal computer for these functions instead, making the system all the more affordable.

IP camera home video security systems can be used to monitor the home when you are at work, on travel, or away for extended periods. They are also great for 24/7 monitoring by professional companies. They can eliminate the added expense of a proprietary camera system that would otherwise be required.

If you are interested in protecting your home with a home video security system talk with one our experts today.

Home Monitoring Over the Internet

Written By:
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.

Home Security Standalone DVR System

Written By:
Monday, May 24th, 2010

A home security standalone dvr system can provide the security and peace of mind for most residential applications. Huge selections in camera types, video recording technologies and monitoring options have made digital video camera systems the ideal choice for home security and monitoring.

Exactly what is a home security standalone dvr system? A home security standalone dvr system consists of the following components:

• Digital video cameras
• A processor/capture board/and CODEC application
• A digital video recorder or DVR, and;
• A monitor if desired

Digital video cameras for home security standalone dvr systems are manufactured in two basic types, indoor and outdoor. Outdoor cameras are usually “weatherproof” meaning they are able to withstand environmental weather conditions like rain, snow, and heat. Indoor cameras are designed for used in covered environments and do not usually contain the same type of camera enclosure that provides protection from the elements.

Both indoor and outdoor digital video cameras for home security standalone dvr systems can be wired or wireless. A wireless camera does not require an image transmitting cable to be connected from the camera to the processing unit. Instead, these cameras transmit their data via built-in antennae to receiver units that are usually located near the processor, dvr, and monitor. Wireless camera units usually transmit their data on the 2.8 or 5.8 MHz radio band and can provide fairly long line of sight ranges for transmission.

Whether the cameras are indoor/outdoor and wired/wireless they can also be day/night vision or infrared (IR) night vision cameras.

Digital video cameras produce a video image by using one of two different types of electronic sensors, both of which can produce color or black and white video. Charged Coupled Devices or CCDs and Complimentary Metal-Oxide Semiconductors or CMOSs convert captured light into electrical energy that can be used to create high quality video images. CCDs and CMOSs can be very sensitive light and create high quality video in very low light conditions, utilizing as little light that is available on moonlit nights for example. Cameras that use these sensors are usually referred to as day/night vision cameras and although they can operate in very low light condition, some visible light must be available to produce a video image.

There are digital video cameras that can operate in conditions of total darkness. These cameras are normally called night vision cameras and operate by creating video images from infrared or IR light. CCDs have the inherent ability to detect IR radiation light which is invisible to the human eye. A digital video camera for home security standalone dvr system can take advantage of this characteristic by “bathing” the target area with IR light. Since the light is invisible to the human eye, we cannot see or detect the presence of the IR light. IR Light Emitting Diodes or LEDs are used to produce the IR light for this purpose. IR LEDs are placed around the camera lens so they are aimed at the same target area as the camera and illuminate the area to record IR video. IR images are monochromatic or black and white.

The home security standalone dvr system is a security camera system that does not require any additional equipment, such as a personal computer to operate. The cameras transmit their data to a processor or capture device that converts the electronic information sent into a digital video file that can be watched on a monitor and stored on a digital video recorder or dvr. Often a COmpression/DECompression (CODEC) programs or wired circuits are used to reduce the size of the digital file while maintaining high quality video images. This provides for easy storage and portability of the file, allowing large amounts of data to be stored.

The digital video recorder of a home security standalone dvr system is much like the hard drive on a personal computer. It is a magnetic storage disk or plate that stores the video in digital file format for later viewing or archival purposes. Files can even be copied to other mediums and viewed on personal computers or DVD players.

Home security standalone dvr systems can be used to for a variety of applications. They are great for providing perimeter coverage of the residence for security and surveillance purposes. They can also be used inside the home to detect and recorded unwanted intruders. In addition they can be used as bay room monitors, nanny monitors, and pet monitors.
