Wonders of IP Cameras

Wonders of IP Cameras

Did you ever ask yourself, what are IP cameras? And what is the thing so special about them? Ok�Ц read carefully each word of this cool article 🙂

IP is an acronym that stands for “Internet Protocol” and an IP Security System is an internet based security system, which uses a LAN network or the Internet as a crucial tool for surveillance. IP system delivers secure and real time images of an event; as well as, the flexibility to show both full motions and still images.

Check out the coolest 5 features of IP Cameras and Systems:

– Cost Effective:
IP Camera System can be cost effective. Firstly, it reduces the cost of cabling in large installation. Secondly, it reduces the network infrastructure by using the same network for both, the transportation of video and control of PTZ (reduce the amount of cables) not as the traditional CCTV which needs two separated cables. Finally, it reduces the space needed because video processes are done via computers without the need of bulked and expensive switches as CCTV systems.

Let me break the idea of PTZ cameras for you;  
Pan, Tilt Zoom (PTZ) Cameras, often referred to as dome cameras, are cameras that can be moved left to right, up and down and zoom in and out via a computer, DVR, or PTZ joystick. This type of surveillance camera is often found at retail stores and allow the operator to follow a person as they move about or to zoom in on someone’s face, a license plate, a cash register etc. some of them are indoor, outdoor, and internet protocol (IP) cameras, each dome camera provides full color surveillance images.

– Secure communication:
By using IP systems, you get the necessary authentication and encryption to make sure that your system is not exposed to hackers. And of course more secure image capture and transmission. On the contrary of the traditional CCTV system which doesn’t have the needed authentication and encryption, and without them, it would be much easier for hackers to get into your system and record everything.

– Real time Events:
IP Camera System records events in real time, and provide triggering alerts and warnings of in progress events in case a suspicious activity is detected such as: blocking, covering, spray-painting or redirection. It also provides an automatic analysis, which makes IP systems more productive means of surveillance and efficient monitoring of large systems.  But the traditional CCTV systems record events for viewing after the event has occurred. Now, what really distinguish IP camera from the traditional CCTV camera is: showing the number of people and objects, audio detection, and face and gender recognition. In a simpler words; IP Camera System records events in real time, and provide triggering alerts and warnings of in progress events in case a suspicious activity is detected such as: blocking, covering, spray-painting or redirection.

– Ease of view and switch:
IP camera system gives you the ability run a number of cameras on one surveillance network; and to view each on one screen. The available software enables one person to switch between cameras; some allow you to view scenes and videos over your mobile phone, which gives you the ability to manage it from any location.

– Perfect Image:
IP camera is the perfect choice regarding the clarity of images because of it’s highly and various resolutions, it is at least four times clearer more than the traditional CCTV system. IP system has higher image quality, full image details, progressive scan and more accurate and specific information. Simultaneous high resolution and low bandwidth streams allowing remote viewing of live video whilst recording crisp megapixel images.  It also has different aspect of rations. IP cameras have wider color spectrum than traditional CCTV; better color representation, full frame rate, and wide screen format.

IP Cameras have solved many problems and obstacle which the users have faced with the traditional CCTV cameras and systems�Ц..So, admit it, IP Cameras really are making wonders in the camera systems technology.

Through the ADSP-BF561 SPI internal bus, the data from the SD card to read the internal SDRAM, the same, SDRAM data can also be written back through the SPI bus, the internal SD card.

SDRAM read from the SD card pictures within the dishes, through a number of processing into 320 × 240 color LCD for display of the RGB-24Bit format image data, and then, through the parallel peripheral interface (PPI) given to LCD controller the dishes picture display.
LAN91C111 chip system as the network expanded master chip. ADSP-BF561 extend through the external interface bus (EBIU), and LAN91C111 read and write communication. LAN91C111 transformer output of the network through the network after receiving the RJ-45 interface, the hardware realization of the network connection. LAN91C111 chip DMA mode and interrupt pin through, and ADSP-BF561 for data transmission. Software, real-time kernel by VDK transplant LWIP, the TCP / IP protocol development.

Video (PAL system) through the coaxial cable access to the ADV7183 video decoder inside, after sampling, video decoding, the output ITU-656 format image data. Image data through the PPI, the 8bit data width, SCLK / 2 speed, DMA transmitted to the SDRAM. Synchronization using PPI data port and ADV7183 frame synchronization, vertical sync, horizontal sync and other signals connected to complete the synchronization of video data. ADV7183 power configuration of the ADSP-BF561, through a common programming interface (PF) I2C protocol to achieve complete data formats, gain control, exposure control configuration.

ADV7183 video decoder to read from the SDRAM of video data is the ITU-656 format (UYVY4: 2:2 format) through the YUV to RGB transformation algorithm, into a color LCD display module RGB24bit for data transmission to the LCD control by PPI , which realizes the video capture and playback.

Customer’s voice through a microphone input to audio codec AD1836, after the audio A / D sampling, quantification, decoded by DSP’s Sport in the mouth temporarily transferred to SDRAM memory [3], followed by MDMA transport to the SD card, the customer views the voice preservation. ADSP-BF561 AD1836 via a serial peripheral interface (SPI) configured sampling rate of 44kHz, 16bit sampling width.

SD card audio data (music) to read through the SPI to the SDRAM, decoded by the ADSP-BF561, through the serial port (SPORT) to DMA mode, the transmission to the AD1836 audio codec, then output through speakers or headphones to achieve the songs playback.
In addition, the system extends as a large-capacity NAND Flash data storage, expansion of the 4 × 4 keyboard and light, extending the Flash as the curing process, extend the fire alarm interface information.

System functions as follows:

View menu: dishes, pictures by SD card to store the BMP format. When the user when browsing the menu, ADSP-BF561 file name through the dishes, read the SD card in the corresponding dishes pictures, displayed on the color LCD. Customers can browse the menu to choose dishes, dishes can also scroll through the play.

Customers ordering: Customers browse through the picture menu dishes, dishes to choose their own satisfaction, then select the button ordering, ordering functions that can be achieved.

In software, on the basis of the VDK kernel transplant LWIP main structure as a network to achieve the TCP / IP on the ADSP-BF561 transplantation [4], completed the CS (client – server) model the establishment of a network Socket , connection, transmission, disconnect the other functions. And, in the standard TCP / IP, based on the application layer protocol developed to realize the ordering terminal and PC computers direct data transmission.

Software Design

ADSP-BF561 to achieve the software through the use of VDK create a thread, the thread through the signals between the amount of (semaphore) and message (message) to transmit information and the completion of thread synchronization. Use hardware signs (device flag) to complete the DSP peripherals and synchronization. Used to handle the interrupt and DMA interrupt nesting and emergencies. By creating a thread for each application, with the priority of the thread and messages to each other’s scheduling and management, and to prepare ADV7183, AD1836 and LAN91C111 drive and other equipment, with priority management interrupt service routine, the API function calls VDK .

Ordering in the network information transmission, DSP-side program mainly in the VDK kernel ported by LWIP TCP / IP protocol stack. VDK as a Visual DSP + + together with the sale of the core, well integrated into the VisualDSP + + in. On the basis of the VDK, Socket server program through the development, implementation of the ordering information ordering network transmission and network function.
The program is loaded in the FLASH in the curing process, after power-up, the program can be separated from the emulator to load and run independently, this step is the process of any one product development work to be done. ADSP-BF561 loading process is very complex, divided into: 1, simple program to load; 2, a single nuclear program loading; 3, dual-core program loading; 4, the complex process (dual core, running in the external memory) to load. VDK kernel of LWIP procedures, and video and audio collection, coding and decoding, etc., make the program a huge amount of procedures to be run in external memory, and dual-core processor must be used to increase processing performance, the design load is the most complex procedures The Category 4 load. In the process of loading process, we start again from the simple test program, ADSP-BF561 gradual understanding of the loading process, by reading a lot of information, with the ADI’s internal and external technical support were contacted, the ultimate solution this problem.

Conclusion

System takes full advantage of dual-core DSP-BF561 hardware resources, making the Blackfin DSP series of audio and video processing performance into full play. Through the rational design of a DSP peripheral device, to achieve the audio capture and playback, video capture and display module, interactive touch screen, SD card and other large-capacity NAND flash memory used. Management procedures using the VDK kernel process of the transplant in the DSP on the TCP / IP protocol stack to achieve ordering information ordering network transmission and network function. Dishes stored in the terminal the millions of images can be dynamically browse and play. Provides a powerful entertainment features. Customers can dine on the dishes after the voice through a terminal evaluation.
The system uses a real sense of “no smart restaurant.”

Mobile Phones

Mobile Phones

A mobile phone allows calls into the public switched telephone system over a radio link. Early mobile phones were usually bulky and permanently installed in vehicles, they provided limited service because only a few frequencies were available for a geographic area. Modern cellular cell phones or hand phones make use of the cellular network concept, where frequencies are used repeatedly within a city area, allowing many more users to share access to the radio bandwidth. A mobile phone allows calls to be placed over a wide geographic area, generally the user is a subscriber to the phone service and does not own the base station. By contrast, a cordless telephone is used only within the range of a single, private base station.

A mobile phone can make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed line phones across the world. It does this by connecting to a cellular network provided by a mobile network operator. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these more general computing capabilities are referred to as smartphones.

The first commercially automated cellular network (1G) was launched in Japan by NTT in 1979, initially in the metropolitan area of Tokyo. Within five years, the NTT network had been expanded to cover the whole population of Japan and became the first nationwide 1G network. In 1981, this was followed by the simultaneous launch of the Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway and Sweden. NMT was the first mobile phone network featuring international roaming. The first 1G network launched in the USA was Chicago based Ameritech in 1983 using the Motorola DynaTAC mobile phone. Several countries then followed in the 1980s including the UK, Mexico and Canada. The first modern network technology on digital 2G cellular technology was launched by Radiolinja in 1991 in Finland on the GSM standard, which also marked the introduction of competition in mobile telecoms when Radiolinja challenged incumbent Telecom Finland who ran a 1G NMT network.

Low end mobile phones are often referred to as feature phones, and offer basic telephony, as well as functions such as playing music and taking photos, and sometimes simple applications based on generic managed platforms such as Java ME or BREW. Handsets with more advanced computing ability through the use of native software applications became known as smartphones. The first smartphone was the Nokia 9000 Communicator in 1996 which added PDA functionality to the basic mobile phone at the time. As miniaturization and increased processing power of microchips has enabled ever more features to be added to phones, the concept of the smartphone has evolved, and what was a high end smartphone five years ago, is a standard phone today.

Other features that may be found on mobile phones include GPS navigation, music (MP3) and video (MP4) playback, RDS radio receiver, alarms, memo recording, personal digital assistant functions, ability to watch streaming video, video download, video calling, built in cameras and camcorders with autofocus and flash, ringtones, games, PTT, memory card reader (SD), USB (2.0), dual line support, infrared, Bluetooth (2.0) and WiFi connectivity, instant messaging, Internet email and browsing and serving as a wireless modem. Nokia and the University of Cambridge demonstrated a bendable cell phone called the Morph. Some phones can make mobile payments via direct mobile billing schemes or through contact less payments if the phone and point of sale support Near Field Communication (NFC). Some of the largest mobile phone manufacturers and network providers along with many retail merchants support, or plan to support, contact less payments through NFC equipped mobile phones.

GSM mobile phones require a small microchip called a Subscriber Identity Module or SIM Card, to function. The SIM card is approximately the size of a small postage stamp and is usually placed underneath the battery in the rear of the unit. The SIM securely stores the service-subscriber key (IMSI) used to identify a subscriber on mobile telephony devices. The SIM card allows users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device. A SIM card contains its unique serial number, internationally unique number of the mobile user (IMSI), security authentication and ciphering information, temporary information related to the local network, a list of the services the user has access to and two passwords.
