The backbone behind any good digital video security system is the surveillance DVR or Digital Video Recorder. It processes the video transmissions sent by the digital video cameras, controls the video cameras, stores the recorded surveillance video footage, and transmits the real-time and recorded video images to the monitor, the internet, or some other output device. In essence, the surveillance DVR is actually the brain of the security and surveillance digital video system.
The surveillance DVR can be directly wired or cabled to the digital video cameras or the cameras can communicate with the DVR wirelessly. In many covert (hidden or disguised) digital video surveillance systems the DVR and camera are an all-in-one compact system.
Another method of communication between the DVR and the cameras uses the Internet for the vehicle of the cameras’ transmissions. This means that cameras can be easily placed in a variety of locations that have Internet connectivity and their signal can be sent all the way around the world via the Internet to a Network Video Recorder or NVR (essentially a surveillance DVR designed to work on the Internet with Internet Protocol or IP ready cameras).
Regardless of the method used to transmit and receive the video transmission signal from camera to surveillance DVR, the DVR’s chief responsibility is to digitally process the information. It does so by using a unique computer processor Integrated Circuit or IC chip called a Digital Signal Processor or DSP.
Digital video consists of nothing more than digital photographs. However, these photographs are taken at a high rate of speed and when presented to the human eye at the same rate, trick it into thinking that we are seeing fluid motion video. Typical high-quality video rate is about 30 photographs, also called frames, per second or 30 fps.
Considering how large a typical digital photograph file can be, you can imagine the amount of digital information in a digital video file. Hence, the need for the high-speed specialized processor called the DSP. Consider that a typical high quality photograph may easily contain enough data to make a digital file approximately 1 Megabyte (MB) in size. For a video file that is 30 minutes long that would be 30 fps x 60 seconds x 30 minutes x 1 MB or a file that is 54,000 MB or 54 Gigabytes in size. Multiply this times 8 cameras and in one half hour typical 8 channel surveillance DVR has processed over 432,000 MBs or 432 GBs.
Considering the tremendous volume of digital data, one can appreciate very readily why a DSP is superior to an average computer processor since it is designed specifically for the purpose of handling digital video data.
The surveillance DVR’s responsibility doesn’t end here though. The DVR processes this data into a digital video file. However, the DVR uses a COmpression/DECompression or CODEC utility to make the file just a fraction of the original size without sacrificing much quality of the digital video.
Security Camera King’s surveillance DVRs currently use the latest, most efficient CODEC called “H.264.” The DSP creates the file using H.264 then saves the compressed digital video file on a recording medium, such as a hard disk drive or some sort of portable memory medium like a Thumb drive or SD card. In addition, it may make the file immediately available for viewing in real-time on a monitor connected to the system.
If the surveillance DVR makes the video available for viewing over the Internet, it also has further processing to do. The DSP now has to either download the digital video file to the requesting computer, or more commonly, convert the digital file once again into a different type of file called a streaming file, suitable for transmission over the Internet.
In addition to all this digital data and file manipulating, the surveillance DVR must also handle the responsibility of coordinating the control of the cameras. Some cameras have Pan-Tilt-Zoom or PTZ functions and the DVR usually instructs the camera what to do with these movements. Other cameras may have audio recording as well that the DVR must also process.
In addition to the camera processing, the surveillance DVR is also responsible for the display of the video image, live or recorded. Considering all of these responsibilities, the importance of a high-quality surveillance DVR in a digital video security system becomes readily apparent. And that’s why Security Camera King only offers the highest-quality DVRs in its digital video security systems.

Safeguard Your Home Or Business With Wireless Video Surveillance
For a long time most places of business and many homes have put into use some kind of wireless video camera for security purposes. These incredible products are now being acquired and put in place easier than ever before. They have also become incredibly affordable over the years and so there is absolutely no valid reason not to have one set up in your house or place of business.
Using state of the art ip video software and ip video servers may help you manage your personal wireless video camera security network and can allow you to monitor multiple cameras from the same monitor. The advanced systems that are commonly used in feature films by mega corporations can be installed and used in your very own house for a remarkably affordable price. Safeguarding your family or business with constant video security has never been easier and more affordable. Wireless video surveillance was previously a luxury that only the major and most profitable firms could manage for their establishments, but now business of all sizes can likely protect their stores.
Anything from independent bookstores to small restaurants can have far more efficient security with the proper wireless video surveillance device. Trying to catch potential shoplifters and many other criminals might be a dangerous experience, however with a wireless video security camera system fitted you can provide the police with the high definition video footage evidently showing the suspect caught in the act. Rather than attempting to apprehend the suspect on their own, the shopkeeper or store owner can easily count on the video footage, which they can then merely present to the police who can subsequently be relied upon to catch the criminal or criminals.
Wireless video surveillance systems can save lives in many occasions, but they can also be used in less serious situations where people simply want to keep an eye on something or someone. Couples often place a wireless video camera in their infant or young toddler's bedroom so that they can safely view their child even when they are not in the same place. Wireless video cameras are also often used as a sort of nanny cam where a system is used to monitor a babysitter or nanny whenever the parents aren't home. These nanny cams allow the parents to make sure their child or children are being properly treated by their sitter. Many people also worry about the threat of theft when they hire a new sitter and wireless video cameras help relieve these fears as well. There has never been a better time to take advantage of the security and peace of mind provided by wireless video camera systems.
Wireless Video Surveillance Camera System For Construction Sites
While in the process of building, construction sites are prone to vandalism and theft of raw materials and expensive industrial equipment. Because of the temporary nature of construction sites, the best security investment may be a wireless video surveillance camera system.
Wireless systems are completely reusable with every new construction site. There's no need to invest in new wiring upon every installation. And installation is a breeze. Once the batteries are charged, just find the optimum location camera surveillance and install the device.
New innovative systems have many features that can be useful for construction sites in particular. Some systems offer monitoring services which frees managers and foremen from having to constantly watch the video feeds to ensure security. Instead, they can focus on the task at hand and concentrate on other things like deadlines and on-site safety regulations.
On the other hand, the same surveillance used for security can be used by head offices to check in on a project or to show investors the progress of construction on-demand. This is because footage from a wireless video surveillance camera can be viewed in real time from any location with internet access. No special software is needed except for an ordinary web browser.
Surveillance systems can be programmed to record scheduled events like important deliveries and crucial parts of the construction process. The features of surveillance systems listed above are largely based on a product called iSee Video which was created and developed by Napco Security Technologies.

A Number Of Magnificent Functions Of Video Camera Security Unit
Yes a basic security system will help to make you feel safe in the beginning. However over time you may want to take more precautions to ensure that not only your home and its content are protected but also your family.
Buying The Right Video Security Camera
Looking for the perfect solution to ensure that your home remains safe when you are not there? Then it is worth thinking about spending money on getting a video camera security system installed.
Wireless Video Surveillance System Information / Home Security Cameras
Wireless video surveillance systems (VSS) are actually easier to install in your home than hard-wired systems. Wireless VSS transmits radio signals from your camera or transmitter to a receiver. The receiver will be connected to your TV or VCR (or whatever kind of monitoring equipment you buy) via a cable, but that's the only cable you'll have to use when you set up a wireless video surveillance system. You don't have to connect the transmitter and the receiver with wires.
Basic Components of a Wireless Video Surveillance System:
at least one camera/transmitter
power supply (typically 12-volt DC)
receiver and antenna
cable (to connect your receiver to your monitoring equipment)
optional additional monitor and VCR
A VCR is only a necessary component to a video surveillance system if you want to record the images being broadcast by your transmitter. Some homeowners will just broadcast the signal live to monitor instead of recording hours worth of footage.
Tools Needed to Install a Wireless Video Surveillance System:
a drill
a pencil for marking your drill spots
a screwdriver
a ladder
a small wrench for tightening cable ends
Before you start installing your VSS though, you'll want to make sure you thought through where to put your cameras and equipment. Draw a diagram of the area you want to cover whether it be indoors or outdoors. Figure out where you can put your cameras where they will be most effective. Remember to read the documentation that came with your cameras.
Wireless technology: the latest model to build video surveillance - video surveillance, technical articles - Security Industry
Video surveillance from the cable into the wireless access mode is an inevitable trend. With the increasing development of wireless technology, Wireless transmission Technology is increasingly being accepted by all walks of life. As a special-use wireless control methods have gradually been optimistic about the user. Its easy installation, flexibility, cost-effective advanced features make the industry more Monitoring System Use of wireless monitoring, establish monitoring points and monitoring center is the connection between. Wireless monitoring technology has been in modern communities, Traffic , Transportation, water conservancy, shipping, security, fire and other fields has been widely used.
Wireless video transmission to break the traditional coaxial and optical images Monitoring Subject to the adverse situation of the hardware connections, with more flexibility and convenience of wireless network based video surveillance system came into being. Wireless video transmission technology has the structure of the wireless mobile networks and protocols had a profound impact, but because of the limited wireless channel bandwidth, interference by many factors, but the video signal data volume, real-time requirements such problems. car key remote control

Three major advantages of wireless transmission China car key duplicate
1, integrated, low cost, just a one-time investment, without trenching pipe, suitable for outdoor distance and has Decoration Good occasion; in many cases, users are often due to geographical conditions and work content of the restrictions, such as mountains, ports and open to other special geographic environment, on cable networks, cable transmission wiring works great inconvenience, with Cable The construction period will be very long, or even impossible to achieve. Then, using wireless monitoring can get rid of the shackles of cable, installed a short cycle, easy maintenance and expansion capability, the advantages of rapid cost recovery.
2, low maintenance cost, wireless monitoring and control is maintained by network provider maintenance, front-end devices are Plug and Play, maintenance-free system.
3, wireless monitoring and control system is a combination of wireless transmission technology, it can be in different locations on-site information in real time via wireless communication means to transmit to the wireless monitoring center. In the wireless monitoring system, real-time wireless monitoring and control center needs to be monitored by point of video information, and the video information must be continuous, clear. In the wireless monitoring point, commonly used Camera The situation in real time on-site collection, a video camera connected to the wireless transmission equipment, and through the radio waves to send data signals to the monitoring center.
Wireless video surveillance transmission technology
Reliable signal transmission channel purpose of the study is to make full use of channel bandwidth; and unreliable channel for transmission in the focus of the study is to make full use of bandwidth resources to achieve reliable transmission, that is fault-tolerant transmission technology. Discussed here in the wireless channel on the video transmission system, its main research is fault-tolerant transmission control. Fault-tolerant transmission control technology under its control method can be divided into three categories: namely, the forward error control, ARQ, and based on the feedback of the joint source and channel coding. Forward Error Control (ForwardErrorControl, FEC), including the channel error correction coding, interleaving packaging technology and optimized packet scheduling mechanism. ARQ techniques based on feedback information including the use of multi-frame reference picture selection mechanism (ReferencePictureSelection, RPS) mechanisms, hybrid ARQ (Hybrid, HARQ) feedback mechanisms and ARQ-based error tracking. As the ARQ-based fault-tolerant transmission control technology has excellent performance, so this highlights the ARQ transmission control-related technologies, and discuss the existing fault-tolerant video transmission system weaknesses.
Forward error control coding using forward error correction method to overcome channel errors. Fluctuations in the channel error probability of more severe cases (such as existing mobile channel), in order to obtain a certain transmission quality, forward error correction coding must be present to increase the estimated worst-case redundancy check bits, which will lead to waste of bandwidth resources. On the already limited bandwidth wireless channel is concerned, obviously can not meet the requirements. To this end, consider the ARQ and forward error control techniques combine, called HARQ technology. HARQ is divided into two types: I type HARQ, the sending side to have some forward error correction coding ability, when the receiver was detected, the first use of forward error correction coding to correct errors. If the error is corrected, then the sender sends a packet reception success of the current feedback information (ACK), the contrary is received failed to send a message (NACK). Sender if received ACK, then continue to send the next packet, otherwise, the re-issue of wrong packets. So I need a strong class of ARQ FEC, in applications where a lower error rate would result in waste of bandwidth resources, but the error rate in the environment can be better than other types of ARQ system throughput efficiency. Only the required class ARQ FEC error detection capability can have, according to error-correcting capability of channel coding theory known, it can play a role in saving bandwidth. When the receiver found in error, send a repeat request; the sending end only the error data transmission with error correction ability corresponding checksum. When the receiver received, if still not correct the error, then continue to send the retransmission request, the sender can choose to retransmit the data and the overall error check code, you can also choose to send a stronger ability to check error-correcting codes, specifically for different control strategies can be adjusted. View of the wireless channel error rate, with the feedback channel usually used for wireless transmission of HARQ-I. Figure 2 shows the use of HARQ-I of the wireless video transmission system, the figure dashed box represents a transmission error control of the process. According to the design principle of HARQ-I, the receiver found that error, the error corrected before the first (shown in the first layer of error screen), if not corrected and the current system to meet the delay constraints, then send the ACK request to let the sender re- outgoing wrong part of the data (second error screen). This retransmission can be repeated to correct data received by the receiver or retransmission delays within the system until the delay constraints. If the retransmission can not be correct even after the end of the packet, the receiver will use the error concealment techniques for error recovery (the third layer error screen). Can be seen, the basic idea of this mechanism is to make use of ARQ techniques mistakes to restore the error, so there will be named "best effort" ARQ mechanism (BestEffort ARQ, BEA, RQ).
As video signals have a strong correlation between time and space, and the encoder can not completely remove this correlation, so the decoder can use to restore the relevance of these residues in some quality video. Restore the quality also, and restored part of the texture and motion are closely related, in general, compared to the texture
Wireless video surveillance
Wireless surveillance is no longer something you only do at home.
According to a new report from IMS Research on the market for wireless infrastructure used in video surveillance, the market was estimated to be worth around $175 million in 2009, in the Americas and EMEA regions combined. Additionally, both the EMEA and Americas markets are forecast to grow at a rate approaching 20% in 2010.
So what is driving this growth?
“Well, the main advantage of wireless infrastructure over a wired network is fairly clear,” comments IMS Research senior analyst Niall Jenkins. “Trenching and cabling over long distances can be expensive and wireless networks provide a cost-effective alternative. This is the main reason why the technology has done so well in the city surveillance market where cameras are required across a large area in locations which already have power but no network connection. Wireless infrastructure is an ideal solution.
“The penetration of wireless infrastructure into other vertical markets in the video surveillance industry has been less successful”, continues Jenkins. “The commercial and transportation markets have seen some uptake in the use of wireless infrastructure; however, in vertical markets such as banking and finance it remains extremely niche as there is a perception that the security system can be breached through the wireless network.
“To better understand the potential for wireless video surveillance in new vertical markets, IMS Research interviewed security systems integrators and installers of wireless infrastructure used in video surveillance. It is clear from these discussions that wireless solutions are rarely the first option. That being said, most integrators see the potential for wireless infrastructure in the commercial, transportation and education markets and, as they become more familiar with the technology, these markets will stimulate growth for wireless video surveillance equipment.”
Wired Or Wireless Video Surveillance, What's The Difference
When it comes to video surveillance, the security of your business is the deciding factor. So, read on if you want to go for wired or wireless video surveillance. When wireless video surveillance counts With a wireless video surveillance system, you can do two things at the same time. You can go over your receipts and check on your kitchen staff in the comfort of your own office. This saves you time from going to the kitchen just to see how work is progressing when urgent paper work needs to be done. The convenience of monitoring the waiters and the counter people is also yours with a wireless video surveillance system.
By adding additional cameras, you can also have an electronic eye keeping watch over the cash register and the restaurant;s entrance and exits. The flexibility of the waterproof ccd camera is enhanced when you add a mobile viewer. You can see all the important nooks and crannies whether you are in the office, in the kitchen, or at the counter. This will deter your staff from loitering or wasting their time, so you get your money worth for their services. Like other restaurant owners, you want to prevent theft in the kitchen and at the cash register. A wireless video surveillance will give you piece of mind and control over your business. Going fully wired The advantage of going for wired video surveillance system is the confidence that a particular quarter of your restaurant is permanently covered.
Other areas in the restaurant that needs your constant scrutiny are the cash register, bar, wine cellar, front door, and exits. A wired surveillance camera cannot be transferred from the kitchen to the cash register, so you have to add more home security cameras and have these installed in these important areas. The wired and wireless video surveillance versions give the same advantages when it comes to your business security. Wired or wireless? The option to go wired or wireless may depend on your needs and convenience. Many restaurant owners get both versions. The also get the pan-tilt surveillance cameras to get more viewing angles. The infrared cameras are also a hit for outdoor surveillance. Depending on your budget, you can start with a four camera package or go full time with 16 cameras ; whether your system is PC or IR Water-proof Cameras. Wired or wireless, you can be flexible. If you want to be discreet about your surveillance, go wireless.
This will cost more, though. However, in consideration of your dine-in customers, this will be just perfect. In addition, a wireless system installation will blend well with your interior. Cost versus security wireless video surveillance may not prevent accidents from happening, but you and your staff can be alerted immediately to prevent more damage from happening. Petty theft can be averted and your staff will be encouraged to perform better. It is not cheap to have a system installed, whether it is wired or wireless video surveillance. It will all depend on the number and type of camera you will get, and the floor area of the establishment. A package may cost anywhere from $2,000 to $25,000. Wired or wireless, the installation per camera will run from $500 to $1,000.
Indeed, when it is about security and your business, penny pinching is non-negotiable.
Wireless Video Surveillance System
With crime rates soaring, people are beginning to take measures to protect themselves. Certain things have to be done in order to protect the family and the home. One of those things is purchasing a video surveillance system. While that may seem like a drastic measure, it will provide families with the peace of mind needed to relax and enjoy life. Those families that are considering making the step toward that kind of protection need to consider how to properly go about purchasing such a product.
It is important that consumers know what they are getting before they purchase equipment. With so many products on the market, consumers can often get tricked into purchasing something that is of poor quality. If a video surveillance system is faulty, it will not do any good. It will not offer any protection to the users, and they will be disappointed with their product. High price does not always mean high quality. That is something that is very important for consumers to realize.
In fact, many places offer a video surveillance system that is not priced high at all, but is of excellent quality. Those who are mindful of staying within a budget need to keep places like that in mind. There are many great deals out there. Consumers just need to know where to look.
If a product has a guarantee of some sort, then there is good reason to believe that it is of high quality. Most merchants will not guarantee a product they do not believe in. Also, consumers need to make sure that the product has undergone testing. If a company makes a practice out of just releasing products without checking them first, they cannot guarantee that they will not send a faulty product to consumers.
Technical support is incredibly important when looking for a video surveillance system. Consumers want to use a company that will offer them assistance as they set their equipment up. Those companies that leave consumers alone after the product is purchased need to be avoided. After all, this kind of equipment can be difficult to install, and it needs to be set up right. Without the necessary assistance, consumers could easily get discouraged.
It is also a good idea to go with the company that is familiar with the industry. If a company has worked in the industry for a long time, they are typically more likely to meet the consumers' needs. They have been around the business long enough to know what is expected of them, and they are more likely to deliver. There is a good chance that they have been able to stay in the industry because they have met consumer demands.
Wireless video surveillance
A wireless video surveillance camera can boost your wireless security at home or business. They are used to catch intruders or monitor a home or office from a far away distance.
