Video Surveillance System Devices

Video Cassette Recording (VCR)

Today, security camera system may consist of many different products and technologies. Many suppliers build pieces of the system, whether it is part of a hybrid analog/digital implementation or an end-to-end networked IP solution. The following sections explain the evolution of the CCTV system, starting with a fully analog system and adding components until it achieves networked capability.

A traditional analog surveillance system consists of analog cameras, time-lapse VCRs and monitors. A coaxial cable runs from each camera to a multiplexing device, which allows multiple cameras recording to one VCR, with a monitor for viewing. The time-lapse VCR allows the operator to adjust when the VCR records so the standard two-hour VHS tapes can he used for much longer. The trade-off results in lower-quality images in return for less frequent tape changes or image overwriting.

Analog CCTV recording systems have been the basis surveillance and monitoring for the past twenty years .This technology is extremely old and outdated and is rapidly being replaced by digital recording technology which now represents over 80% of all new installations.

Digital Video Recording (DVR)

A DVR is a computer with a special video graphics card that connects it to an analog camera via 75-ohm coaxial cable. The card also converts the analog signal to a digital signal and compresses the resulting image so it can be stored on an internal hard drive, viewed or transported across a network. DVRs typically utilize a computer operating system such as Windows or Linux along with video management System (VMS) software. DVRs are controlled and accessed via keyboards, mice and external monitors in order to setup, run surveillance software and replay stored video. DVRs usually have an internal Ethernet connection for LAN or WAN attachments.

Network-Attached Digital Video Recorder (NDVR)

A Network-attached Digital Video Recorder is part PC and part “Network Appliance” A NDVR is very similar to a DVR and is sometimes called a “Network Appliance” because it does not require-attached keyboard, mouse or video monitor. The device is plugged directly into an Ethernet switch and the only way to access the device is through the network. The device still has an operating system but it resides in firmware burned into a chip on the motherboard. Most of these NDVRs rely on Video Management Software (VMS) loaded on a network-attached client PC, however some have it ‘embedded’ in another motherboard chip, where it can be accessed from any PC through an Internet Browser. Most of these products have internal hard drives for local video file storage, but they can be inter-connected with Direct Attached Storage Arrays (DAS), Network Attached Storage (NAS) equipment or Storage Area Networks (SANs) through the LAN or WAN.

Network Video Recorders (NVR)

The ‘pure’ Network Video Recorder (NVR) is not a “turn-key box” or network appliance, but created with a combination of network devices. An NVR can be a standard network server with internal or attached storage capability along with recording software, video surveillance system or communication software and possibly even intelligent video analysis software. Digitization of the analog video is done by a separate ‘Video Encoder’ or ‘Video Server’ which is also attached to the Ethernet/IP network. Using an NVR configuration, true IP cameras can act as Video Servers and input images directly to the NVR and be managed directly by the NVR video software.

Video Encoders & Decoders

Encoders are used to take video signals in analog or digital form and make them suitable for transmission where bandwidth or storage capacity is an issue. Encoding applies to many video surveillance system applica­tions where digital recording devices are used or viewing across a network is desired. Analog signals must first be converted to a digital format, but then each source must be compressed into a smaller size file or video “stream.” There are several standards for encoding/decoding and compression; each has advantages and disadvantages. Typically the trade-offs are quality for reduced file size.

A decoder is a device that does the reverse of an encoder, undoing the encoding so that the original information can be retrieved. The same method used to encode is usually just reversed in order to decode. These are still relatively simple devices which can be a software program running on a PC, a DVD player or even a cell phone. They may also be hardware devices that take the digital video format and convert it back into an analog signal that can be displayed on a TV monitor. This allows the networked video to become switched across any output device. Usually the decoding and encoding functions reside in the same device and is commonly referred to as a “codec,” an acronym for code/decode.

Migration to a Digital Network Solution

Because there is significant financial investment in analog CCTV, many security managers opt for a phased transition to IP, blending both analog and digital security technologies wherever possible during the migration. Integrating existing analog equipment with products that provide the functionality of a digital system offers several benefits:

Remote accessibility
Cost-effectiveness
Flexibility
Scalability

In the simple illustration below, the analog cameras are connected to an analog video switcher, an analog monitor, a VCR and a video server. This traditional setup provides sequential monitoring and recording of multiple analog cameras. By connecting a video server to convert the analog video into digital data, images can be sent over an Ethernet/IP network (through a router/switch) which provides Ethernet connections for networked IP cameras. With this configuration, authorized security personnel in local or remote locations can view video originating from both analog and digital, networked IPcameras.
In the transition from analog to digital surveillance systems, no system is too small or too tightly tied to analog technology not to benefit from some measure of digital technology.

In conclusion the migration of a Digital Network Solution to your existing Analogy System can be done and still have the capability to add the latest software and hardware.
Some of the latest in security surveillance system software is the Dual Sensor as listed below in more detail.

The latest camera systems would be a combanation of network camera and high end analogy cameras.

Video Content in Cell Phones and Other Mobile Devices

Mobile internet costs

Take a look at US telecommunications giant – Verizon.
Verizon Wireless and other big mobile operators like Sprint Nextel have spent billions of dollars building 3G multimedia networks, and now they have to generate revenue through new services such as paid video. Certainly, these
3G networks are also ideal for carrying other data services such as mobile e-mail and different mobile applications. But using them to deliver music and video content wirelessly is a much easier concept to sell to consumers.

According to IDC, only 6.9 million, or 3 percent, out of 230 million mobile-phone subscribers in the U.S. are expected to view video on a mobile device by the end of 2006. And even though that number is expected to grow, analysts don’t believe mobile TV watching will hit the mainstream anytime soon.

By 2010, IDC predicts that only 9 percent of cell phone subscribers in the U.S. will tune in to TV on their mobile phones.

Verizon take additional $15 per month for its mobile-video services and I think that for the most people it is still expensive. May be in the future this mobile video services could be based on Mobile Advertising platform and mobile Ads revenues can close investments and other costs.

As a matter of fact, in February had launched the first mobile Ads for the iPhone.

Ad Infuse is serving up ads from Esurance and the Partnership for a Drug-Free America on several sites, including Health & Fitness Mobile for Men and MondoMedia.com. (posted by news.com).

The Ads effect in iPhone was not good, because the tester had to wait 5 min Ads downloading process. The main problem was a slow internet connection in iPhone. It could be better, if mobile infrastructure can tune mobile connections and mobile video stuff.

Mobile video content quality

The other basic aspect to win new customers in mobile multimedia niche – the quality of mobile video content.
Sure, that all people would like to watch videos only in good quality, they are all take care of eyes!

We are talking about DVD length movies for iPhone or cell phones.
Good quality video content take a lot of time for encode-decode video in appropriate mobile video format with the best video / audio options for different cell phone models.

Any way, it’s a lot of work (time and money) for companies, which deliver this ready video content to mobile carriers.
Another alternative for mobile fun is YouTube mobile service. It’s free for use, like YouTube web site version, but they are only amateur videos and other video stuff, but also here exist a lot of limits, e.g. your cell phone need to support RSTP data streaming protocol, your mobile carrier must provide RSTP internet connection and so on. I am talking now only about US and Canada for other world this service is too expensive and now a day not supported from mobile operators.

So, a good quality mobile video content is additional investment for mobile operators, who want to take a big part of pie in this mobile niche, but it’s still in development process!

——————————————————————————————————————————————————————-

We have also other alternative to watch videos in cell phones, this aspect we discuss here.

In Internet you can find a huge of software and online video solutions.

I am convinced, that today this method (for watch video content in cell phone) use 90 % of people in the world, inclusive USA and Canada.

If you use software solutions, it takes a lot of time to find your favorite video, convert it in appropriate mobile video format (e.g. 3gp video format) and than transfer converted video to cell phone (via Bluetooth or USB cable). Well done! After all this steps you can watch this video in cell phone.

Basically, software solutions are difficult for normal internet user and you have to purchase it.

The main difficult position, using software video convert solutions is to know all video / audio options for converting video (video bit rate, audio bit rate, video size etc.). For example, for 60 min DVD movie you will spend 25-30 min of time if you know the right video convert options plus memory in your cell phone.

Other negative aspect is available memory in your cell phone for store converted videos content.
Sure, that memory in cell phone is limited factor and therefore it is disadvantage for most of us.

It’s not a secret, that everyone would prefer to use mobile video content in cell phones and iPhone, saving the time and money at the same time!

Now this perfect solution for mobile video content search many companies!!!

In the next time, we will discuss the great aspect, how to watch videos in cell phones, iPhones without spending much time for convert videos to cell phone and store it in mobile phones, do not thinking about memory space!

Stay tuned – we will write new reports!
