Night Time Outdoor Security Camera Kits

Written By:
Thursday, December 23rd, 2010

If you have property that you need to protect or monitor during low or no light conditions consider purchasing night time outdoor security camera kits. These kits can provide you with all the equipment you need to effectively monitor and protect your property, without the need for expensive outdoor lighting. Thanks to modern technological improvements, these kits are reasonably priced as well.

So what do night time outdoor security kits contain? Kits may vary based on manufacturers or vendors, but most kits contain at least two major components of a digital video security camera system: 1) Very low light or no light outdoor security cameras; and, 2) A Digital Video Recorder (DVR) with a Digital Signal Processor (DSP). Since monitor applications differ, and many systems may be able to use an existing computer monitor for your security camera system, monitors are usually sold separately from the kit.

Security Camera King offers a variety of digital video security camera kits including night time outdoor security camera kits. However, in addition to the digital video cameras and a DVR, Security Camera King’s security kits come complete with either plug and play camera cables or bulk cable, and either a multiple channel space saving power supply or a multiple channel power distribution box.

A night time outdoor security camera kit is a highly specialized type of digital video security camera system. These systems contain cameras that are designed for outdoor use and can record video in very low-light or no-light conditions. Let’s take a look at these cameras.

First, there are two basic types of digital video security cameras, indoor and outdoor. Indoor models are designed to operate under the protection of a building or cover of some type. They are not designed to operate when exposed to weather or the elements, such as rain, snow, hail, ice, etc.

Outdoor cameras are designed to operate in outdoor settings, exposed to and offering protection to the camera from, weather and the elements. The cameras are normally enclosed by a protective covering. Outdoor cameras are often rated with an International Electrotechnical Commission (EIC) code or rating that indicates the degree of protection that is provided to the camera. The rating is called an IP code or IP rating.

An IP code consists of the letters “IP” followed by two digits. The first digit indicates the size of the object that the camera is protected from ranging from 0 (meaning no protection) to 6 (meaning dust tight). Numbers from 1 – 5 indicate different sizes ranging from >50 mm to particles the size of dust. The second digit indicates the degree of protection against liquids ranging from 0 (meaning no protection) to 8 (meaning protection from immersion beyond 1 m in depth). For example, a very good IP rating is IP66 which means the camera housing is dust tight and offers protection against powerful water jets from any direction.

Night time outdoor security camera kits normally include digital video cameras that are specifically made for low-light (also called low “lux”) or no-light (infrared) use. “Lux” is a measurement term used to measure the intensity of light. For example, the light available in full daylight, but not directly in the sun ranges from 10,000 to 25,000 lux. In contrast, the visible available light of a moonless clear night sky is approximately 0.002 lux. Low-light or low-lux cameras can record video in lighting conditions as low as 0.002 lux, depending on the quality of the camera.

No-light cameras are usually called night vision infrared cameras. These cameras are designed to record high-quality video using near infrared illumination. The cameras sensor chip can detect near infrared spectrum radiation just like visible light; however, this illumination is invisible to the human eye.

Infrared cameras usually have an array of infrared Light Emitting Diodes or LEDs that surround the camera lens or are placed next to it so that their infrared illumination is focused on the same field of view as the camera. There are also LED “Illuminators,” separate arrays of just LEDs that can provide illumination for the camera also. Generally, the more LEDs the longer the range of the camera, so when purchasing these cameras be sure they have the night time range that you require.

Night time outdoor security camera kits have come a long way with the technological advances in computer and electronic components. Security Camera King offers several different night time outdoor security camera kits. Check out our products under “Security Camera Systems.”

Wireless Spy Camera

Written By:
Wednesday, November 17th, 2010

There are times when covert digital video monitoring is needed and nothing can fulfill your security and surveillance needs like wireless spy cameras from Security Camera King. We offer a full line of wireless spy cameras that maintain their concealed identity, transmit their video images without the need for wire hook-ups, and produce high resolution digital video.

Digital video security and surveillance monitoring can be classified into two different types based on whether the monitoring is obvious or purposely intended to be concealed. In the security video industry, these two categories are often referred to as covert (meaning hidden, stealthy, or concealed) and overt (meaning obvious, open, or unconcealed). Covert cameras that broadcast their digital video using radio signals are often referred to as wireless spy cameras.

Wireless spy cameras can be classified into two different types as well based on how the camera achieves being overt. Wireless spy cameras do this by either being incredibly small or disguised as some other object other than a security camera (or some cameras may use a combination of both). The incredibly small types of cameras are often referred to as pinhole type cameras and these are often designed to be disguised as very small objects as well. In order to understand how this is possible, let’s take a look at an incredibly small wireless spy camera and see how it works.

Digital video cameras work by focusing light images on a sensor that can transfer the light energy of the image into electrical energy. There are two different sensors that may be used for this purpose; a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS.

Each sensor performs the same task (transfers light energy into electrical energy that can be measured) but goes about it in a slightly different way. Typically, CCDs have provided a higher quality picture while CMOSs use much less electricity to operate. However, as electronic technology advances both are producing high resolution video images with a minimal amount of power needed to do the job.

These sensor chips, usually in the shape of a square, can be very small, as small as only 1/4″. Today’s electronic technology can produce incredibly small Integrated Circuit or IC chips that house the circuitry for processing video images, converting them to radio signals, and transmitting them to a receiver. Advanced lens physics and manufacture can produce a small wide-angle lens as small as 3.7 mm for example. Combine all three of these technologies and you could produce a wireless spy camera as small as the head of a screw or a button that produce high quality video images. In fact, Security Camera King carries two such cameras, our 2.4 GHz wireless button camera and our 2.4 GHz wireless screw camera.

Wireless spy cameras labeled as “2.4 GHz” refer to the technology that is used to transmit the wireless signal. A 2.4 GHz wireless spy camera uses the same high-quality dependable technology to transmit its radio signals as many land line based wireless telephones. The transmitter and receiver are tuned to a frequency in the 2.4 GHz radio wave spectrum.

The term “wireless spy camera” may impart a connotation of negativity associated with its name. It’s important to note that wireless spy cameras are not necessarily used for this purpose but may be used for the sake of aesthetics in appearance. Our 2.4 GHz Wireless Dog Baby Monitor Camera is a fine example.

Some wireless spy cameras may be used as standalone monitor systems. That is, the camera/transmitter unit comes with its own receiver/monitor. These units are usually designed for monitoring and not recording so although they may come with their own portable, handheld LCD monitor, they often do not record. Our wireless dog baby monitor camera is a good example of this; typically it is not necessary to record baby monitor transmissions.

Other cameras may be designed to use with a standalone video security system that includes a DVR   for storing video. These cameras may or may not come with a receiver, so it’s important that you check on this in the camera’s description or specifications area.

Sometimes the greatest advantage of using digital video security cameras is the ability to monitor and record activities without any indication that video monitoring is occurring and Security Camera Kings wireless spy cameras do just that.

Security Camera System for Courthouse

Written By:
Thursday, November 4th, 2010

A security camera system for courthouse use can augment other security systems such as metal detectors, guards, and bailiffs. While we tend to think of courthouses as extremely safe and secure facilities, they do have the potential for violent outbreaks. Further, if such a situation should occur, nothing can provide better documentation of the event than a digital video security camera system.

Is it really necessary to have a security camera system for a courthouse? Absolutely; while most courthouses have armed guards and metal detectors for protection, a digital video security camera system can also help deter violence, document criminal events, and protect courthouse employees.

In addition, most courthouse security measures focus on the interior of the courthouse. A digital video security camera system for courthouse use can provide not only interior coverage but just as important, exterior coverage where undesirable events may first begin.

Another advantage of a security camera system for courthouse use is the deterrence of violence and vandalism. It’s a proven fact that digital video security cameras do deter criminal activity. The statistics to support this fact have been shown in both New York City and London, England where police agencies use video security surveillance to monitor day to day street activities. Potential vandals or other criminal perpetrators are less likely to follow through on illegal acts if the know they are being watched and recorded by video cameras.

The occurrence of an unlawful act even in a courthouse requires proper evidence. Nothing can provide documentation for proof and evidence better than a digital video security camera system. A security camera system for courthouse use includes a Digital Video Recorder or DVR. Video images are converted into digital video files and saved on the DVR for later use if necessary. DVRs with CD/DVD writers or thumb drive writers can even provide multiple copies of video footage for distribution to law enforcement agencies, prosecuting attorneys, and other courthouse personnel.

Needless to say, working in a courthouse can be extremely stressful. Since there are always two opposing sides to every issue, there’s bound to be unhappy, tense, and impatient people that must interact with other courthouse employees. Unfortunately, there are isolated incidences where these emotions run rampant resulting in outbursts against courthouse employees. A security camera system for courthouse use can not only spot incidents when they begin and document them as they occur, but help deter them from occurring in the onset.

Another benefit of digital video security camera systems is remote control and monitoring of the system. Thanks to advancements in computer and electronic technology, a security camera system for courthouse use can be remote controlled from just about any other off-site location that has a broadband Internet connection. Authorized users can monitor and record Internet Protocol (IP) ready cameras in a totally different physical location than the system. This feature can be particularly beneficial in the unfortunate event of bomb threats, taking of hostages, and other acts.

The use of Pan-Tilt-Zoom (PTZ) cameras, especially in courthouse parking lots, can provide an early warning of an event before it reaches the inside of the building. Furthermore, DVRs with object tracking can detect motion and automatically pan, tilt, or zoom the camera to track or follow a vehicle or individual.

Maintaining the ultimate security of a courthouse is tantamount to maintaining justice. The very nature of the events that occur within a courthouse and the fact that individuals suspected of murder, manslaughter, and other violent crimes are brought to a courthouse for trial indicates the necessity for proven security measures.

A properly designed and installed security camera system for courthouse use will provide images of all individuals that enter and exit the building. Public areas within the courthouse can be monitored by video security cameras, freeing courthouse guards to provide their services where they are needed the most.

Security Camera King has some of the most sophisticated electronic digital video security camera systems available.

Outdoor Motion Activated Security Surveillance System

Written By:
Thursday, November 4th, 2010

An outdoor motion activated security surveillance system is an excellent tool to provide security and surveillance for almost any residential or commercial application. Modern technological advancements have made this surveillance system incredibly versatile and reasonable priced as well.

An outdoor motion activated security surveillance system’s cameras are specifically designed for outdoor use. These cameras (as opposed to indoor cameras for example) are designed to be housed by a protective enclosure. The enclosure protects the camera from weather, dust, and other objects.

An outdoor security camera may be rated according to the protection that is afforded to it by the enclosure or its casing. This rating, an Electrotechnical International Commission (EIC) standard, is call an Ingress Protection rating, IP rating, or IP code.

The rating consists of the letters “IP” followed by two digits, for example IP65. The first digit of the rating describes the extent the camera is protected from solid objects and the second digit indicates the extent the camera is protected from liquids. The example IP65 rating means the camera is dust free and protected from water sprayed from nozzles in any direction.

The first digit of an IP rating for an outdoor motion activated security camera system ranges from 0 – 6 with 0 indicating that there is no protection against contact or ingress of objects. As the number increases from 0 to 6, the rating indicates that the camera is protected from objects continually smaller in size. A first digit IP rating of 6 indicates no dust and complete protection against contact.

The second digit of an IP rating for the camera ranges from 0 to 8 with 0 indicating that there is no protection from water. As this digit increases in value the rating indicates progressive protection from water with 1 meaning protection from dripping water and 8 meaning continuous immersion in water.

An outdoor motion activated security camera system also has a unique characteristic as indicated by its descriptive name. The cameras only record video when motion is detected.

This is accomplished by an on-board Passive InfraRed (PIR) sensor. The PIR sensor can detect the infrared radiation from objects in the camera’s field of view. If the sensor detects a significant change in the infrared radiation in this view, it assumes it is created by a moving object; hence it detects “motion.” The sensor is connected to a relay that turns the camera on in recording mode to capture the video images. The camera shuts off or stops recording when the sensor detects that the motion has stopped or after a pre-programmed period of time.

This feature, though small and simple in design and appearance, can offer tremendous benefits in the functioning of a security camera system. Since the camera will only record video when motion is detected, this can save a tremendous amount of file space use on the system’s Digital Video Recorder or DVR.

Since the DVR records video images in sequence, it will continue recording until the DVR’s storage capacity is full. Once the DVR is full however, the video image files are rewritten over the files that are the oldest, continuing this process until the DVR is full and then repeating the process over and over again. A motion detector activated camera can extend DVR recording times before repeating and rewriting, significantly.

In addition, a motion activated security camera system camera must have a power supply. This may be in the form of a small, low-voltage Direct Current (DC) power line run from a power distribution center to each camera or from a nearby plug-in transformer. Many cameras have the ability to operate on the power supplied by batteries, either one time use types or rechargeable types.

The PIR sensor on a motion activated security camera uses a very small amount of power to stay on. In fact, compared to the power required to capture video, the PIR sensor’s power usage is significantly lower. Motion activated cameras that operate on battery power last significantly longer between charges or battery changing because the motion sensor, in effect, conserves battery power.

There are many additional/optional features that contribute to the versatility of an outdoor motion activated security camera system. Some of these features include:
• Pan-Tilt-Zoom (PTZ) functions
• Day/Night vision
• Night vision infrared recording
• Wireless cameras
• IP ready cameras and/or DVRs

These features coupled with the motion activated feature make the outdoor motion activated security camera system appropriate for almost any commercial or residential application.

DVR and Security Camera Systems

Written By:
Monday, September 27th, 2010

What is the relationship between a DVR and security camera systems? Is DVR necessary in a security camera system? What kinds of DVRs are there? Are there substitutes for DVRs? What is a DVR anyway?
Let’s examine a basic digital video security camera system and how it operates. Afterwards, we’ll be able to answer some of the specific questions related to the DVR and security camera systems.

A basic digital video security camera system is a component system that consists of three major components:
1) One to many cameras;
2) A DVR or Digital Video Recorder; and,
3) A monitor or monitors

The system operates in the following manner. The digital video camera converts light energy into electrical energy which can be measured and is used to create digital video data. This data is sent to the DVR. As previously mentioned, the DVR is a digital video recorder, just like the hard disk drive or HDD of a personal computer. However, in security camera systems, the DVR normally contains a processor, just like the processor in a Personal Computer or PC.

However, the processor in a DVR is a highly specialized piece of electronic circuitry. Unlike the PC processor, the security camera DVR processor is manufactured to handle specific functions of security camera systems such as digital video file production, camera control, and recording of digital video files. It uses a specific utility called a COmpression/DECompression or CODEC program to process the digital video file from the digital video data sent to it by the video camera.

Digital video is basically nothing more than a series of rapid digital photographs taken in rapid succession. Typically, high quality digital video is about 30 digital photographs taken within on second, also referred to as 30 frames per second or 30 fps. When you think of the file size from just one high quality digital photograph, you can imagine how enormous a digital video file that takes 30 fps for 24 hours could be.

That’s why the DVR’s processor uses a CODEC to create the digital video file. It uses special programming that shrinks the size of the file without sacrificing the high quality of the image. CODECS change from time to time as different approaches and technologies make each CODEC better and more efficient. One of the most popular and recent CODECs is called the H.264 CODEC.

The DVR and security camera system create, process, and store digital video files that can be viewed instantly (live) on monitors or stored for later viewing on monitors or for archiving. Many DVRs also have additional storage options such as CD/DVD writers or USB Flash drive connectivity to copy portions of video to portable media. This may be necessary to give insurance companies, police departments, as evidence, etc.

The DVR may also contain other specialized features. One common feature of many modern DVRs is internet connectivity. The DVR may contain its own web server technology and programming so that it may be connected to any broadband internet service and instantly become accessible anywhere in the world there is broadband internet accessibility.

Most DVR and security camera systems come in 4, 8, or 16 channels. This means that the DVR can handle 4, 8, or 16 separate camera inputs at one time. Security systems requiring more than 16 cameras simply use additional DVRs to expand the number of cameras needed.

Highly specialized security cameras may have highly specialized DVRs. Portable systems, systems that are used for a small amount of time, systems that have self contained cameras and DVRs all in one unit may utilize different digital storage methods for the DVR. For example school bus DVR and security camera systems often use a Compact Flash Card or similar portable storage medium instead of a full sized hard disk drive as the DVR.

Is a DVR necessary in a security camera system? No, not necessarily, but a system with just a monitor and no DVR will not be able to record the video so that it may be reproduced for later use. A baby monitor is usually a good example of this. On the other hand, a retail store facility would not realize the full potential of protection without a DVR and security camera system.

Other DVR and security camera systems functions pertaining to the DVR may include audio recording, various output display resolutions as well as connectors, remote control, e-mail and smartphone notification, and mouse and/or keyboard control.
