HD transmission mode and characteristics in supervision system

With the Networking, high definition, intelligent, integration developing, Supervisory system transmission technology are continues to innovation and upgrading.

As an integral part of the monitoring system, the different transmission modes have different characteristics. Based on the camera's output signal, HD video surveillance has a variety of transmission mode.

HD Web Camera: that adapt the standard Ethernet transmission, the short distance transmission adapt the unshielded twisted pair, the long distance transmission mainly adapt optical fiber or wirelessly. Optical fiber transmission mainly use Ethernet optical fiber transceiver, Ethernet switch, PON and other equipment. Wireless adoption of 3G, 4G, WiFi and WiMAX .

Network transmission is the mainly transmission mode of high-definition video surveillance since it’s have small transmission bandwidth, low cost, flexible networking features character. But at the same time, but the compressed video quality, latency, the clarity of the movement of the process is not so good as non compressed video. So it not suitable for someone has higher requirements of video quality .

HD-SDI cameras: the HD digital component serial interface (BNC interface ), non compression way. Coaxial cable is used for short distance transmission, long transmission distance through fiber, HD-SDI optical equipment. The HD-SDI transmission method can transmission high quality image, high level safety, no latency, it suitable for applications at high requirements both image quality and safety. Due to HD-SDI video transmission bandwidth is 1.485Gbps,  take high bandwidth will add the network cost, at the same time group network also have the limit, only the use of point to point optical fiber transmission.

At present, there has come out a visual lossless coding technology to solve HD-SDI bandwidth problem, which uses an HD-SDI interface , in the transmission of HD video visual lossless coding, that can reduced the bandwidth to 1 / 6 of the original. HD video visual lossless coding can be greatly reduced the cost, single wavelength can support 8 HD-SDI video transmission and networking also support node type transmission.

With the development of technology, combined with the new intelligent analysis technology and cloud storage technology, security will gradually enter the 4K image application. As a high-definition video transmission applications also faced more hardly test, the high-definition network transmission technology requires higher bandwidth , more high chip technology, higher application platform, more demanding work environment, more clear image.

How to make sure HD transmission effect in supervision system?

Market has come out many kinds of HD transmission method, the aim is transmit audio video and date to the needed place by different carrier, but in this section stable transmission is the key of video monitoring system.

HD monitor is a unified whole, involving a number of aspects of the monitoring system, including front-end video capture, video transmission in the middle, back-end HD storage, display, analysis, linkage and so on. From the point of view of the transmission link, how to ensure that the information clearly and effectively?

Transmission as an integral part of monitoring system , how to ensure the integrity of video and data signals transmission in the project?

Transmission scheme : the above transmission mode has its own characteristics, and construction project system use at the different environment , so the choice conforms to the transmission mode of the project is very necessary. For example: long transmission distance should be choose optical fiber transmission; in the preliminary planning of transmission should considering the issues of the bandwidth, and the issue of the whole system bandwidth, we must detection and confirmation according to the real condition.

Wire section: that’s the essential factors of the system operation is long-term or short-term, for example: the SDI signal transmission, as a serial digital signal on the transmission rate requirements is very high, coaxial cable will be the best carrier of short distance transmission in this project, but coaxial cable has many kinds specifications , so this is a difficult task for select the wire.

Customers' question about Wireless A/V Transmitters and Receivers

Question: I have cable service in my living room only. The apartment manager won't let me run a cable to my bedroom. Is there a device that will let me remotely have TV in my bedroom without running a cable?

Answer: Yes, there is. It's called a wireless A/V transmitter. Some people call it wireless tv sender too. On a small scale, it works the same way as a TV antenna only instead of a local broadcast station sending a signal out to anyone who has an antenna, the TV in your living room will be the sender of the signal for the receiver in your bedroom to decode.

The way it works is connect the television in your living room to the av transmitter, and the TV in the bedroom to the av receiver. The signal travels through the open air, and is decoded by the av receiver in the bedroom. My advice is to have the transmitter and receiver in as open a space as possible to avoid any interference.

Line of sight is a term used for wireless transmissions. This is where the transmitter and receiver can see each other.

Question: I have four tv in my home, can I use wireless av sender also, the resolution is same, the video will be  delay if I use too much receiver?

Answer: Yes, you can use one av transmitter with multi-receiver, the av receiver is no upper limit; the resolution would not influence by receiver quality, all receiver could get the same resolution and display at monitor;

The video would not be delay, it’s different with wifi router, if too much device connect with wifi router will reduce the upload rate, but whatever how many pcs receiver you connect with one transmitter, the video would not be delay, it’s vivid transmission.

PAKITE PAT-433 Wireless IR Remote Control Extender

As we know, most of device infrared remote control distance only has 5 meter or less, so PAKITE develop one IR Repeater for help user control at long distance.

PAKITE PAT-433 is Wireless IR Remote Control Extender, like an infrared amplifier. PAT-433 adapt 433.92MHz ISM Frequency Band wireless transmission, extension distance around 200 meter, it support 38KHz frequency band, if you need both 38/56KHz frequency band, you can talk with PKAITE sales and check more details.

IR Repeater is only for extension infrared range, can not transmit audio video. if you need transmit audio video at the same times, you may got the wrong model, if like this condition, you can choose wireless av sender, not IR Repeater.

Wireless av sender also has infrared repeater function, but it’s totally different product. Wireless AV Sender mainly is for transmit audio video, it also extend the ir remote control range. But PAT-433 IR Repeater is only for extension infrared signal.

Besides, PAKITE wireless av sender mostly is RCA Jack as connection, but PAKITE pat-433 IR Repeater is no need to connect with the device, just place the IR Repeater receiver parts above the device and control at the transmitter side, then it will be work. It means wireless av sender is only for RCA Jack device, but IR Repeater can be used with any device with infrared remote control.

PAT-433 is worthwhile to try, it’s real wireless connection, whatever you device is, as IR Repeater PAT-433 can extension it’s remote control range.

PAT-556, Send Your TV Signal Wirelessly to Another Room

With wireless being the norm for so many of our electronic devices today, it’s pretty surprising to me that the standard way to connect a cable box to your TV is still with physical cables. And the surprise turns into annoyance when I want to put a TV in a room where I don’t have a cable outlet.

I had this situation when I bought my current house. I wanted to put a TV in my living room but there was no outlet there and neither option for putting one in—running the wires along the ceiling and floorboards inside the house or running them over the roof on the outside—was desirable. 

Fortunately, after doing some research, I found the Pakite 8-Channel audio video Wireless TV Sender (contain a Transmitter and a Receiver) System with 2 groups of AV Input (Model PAT-556), which sends the cable signal wirelessly from the cable box in my bedroom to my living room TV.

The value of the second input is that you can use these same devices to transmit signals wirelessly from other types of audio and video equipment as well, e.g. DVD/Blu-ray players, streaming media devices, music systems, gaming consoles, etc. I have my transmitter set up with the cable box as one input and a Roku streaming player as the other. These systems can also be useful even if you have them in the same room as your TV, but connecting devices with a cable isn’t ideal, e.g. if the TV is mounted on the wall.

One of the questions that comes up a lot with these types of systems is how do you control A/V devices from another room (e.g. change the channel on your cable box)? That’s where the IR extender comes in.

The IR extender is a thin cable that plugs into the av transmitter and has one or more small blocks on it. You position the block close to and in front of the device’s infrared light (hence “IR”). Then when you point the device’s own remote at the receiver unit, which is connected to the IR extender, you can operate the device just as if you were pointing the remote at it directly.

 So all that to say that I’m extremely happy with—the picture and sound quality is excellent, there’s really no way to know if it’s going to work with your own setup until you try it out yourself.

A wireless tv sender (also known as a audio video transmitter receiver, wireless video sender, wireless AV sender or DigiSender) is a device for transmitting domestic audio and video signals wirelessly from one location to another. It is most commonly used for sending the output of a source device, such as a satellite television decoder, to a television in another part of a property and provides an alternative to cable installations.

A wide range of wireless tv sender technologies exist, including analogue wireless (radio), digital wireless (spread-spectrum, Wi-Fi, ultra-wideband) and digital wired (power-line communication). Other, less common, technologies also exist, such as those that utilise existing Ethernet networks.

A typical wireless tv sender kit containing a transmitter, receiver, magic eye and a remote control to select the input. 

Video senders have been a frequent cause of RF interference, particularly with car key fobs

Overview

Typical wireless av sender applications include the transmission of television audio and video signals from a lounge to a bedroom or from a CCTV camera to a display, as well as interconnecting appliances with audio, video and IP (Internet Protocol) requirements.

Most wireless tv sender systems will consist of three separate components, a transmitter, a receiver and a remote control relay (also known as a magic eye or IR blaster). The transmitter is responsible for transmitting or broadcasting a connected audio-video device, while the receiver outputs that transmitted audio-video signal to a connected television. The remote control relay permits infrared remote controls to operate the equipment whose output is being transmitted.

Analogue wireless

Analogue video senders have the advantage of low manufacturing costs as the audio and video signals are simply modulated onto a carrier at 2.4 GHz or 5.8 GHz. They do, however, have the adverse effect of causing reduced bandwidth to local Wi-Fi networks and, in some cases, Wi-Fi networks can cause picture interference on the video sender signal. More information can be found in the article on electromagnetic interference at 2.4 GHz. To avoid this, some video senders now use a spread-spectrum technology and can co-exist with wireless networks and share available bandwidth.

Usually there are four FM transmit channels, A, B, C & D, with stereo audio on 6.0 MHz and 6.5 MHz FM subcarriers added to the composite video baseband. These different channels can often be used to overcome the adverse effects of nearby WiFi networks.

The reverse remote control channel is usually fixed at 433.92 MHz, using whatever modulation is on the 34 kHz to 45 kHz IR remote "carrier".

Analogue wireless tv senders can achieve typical operating distances of up to 60 metres (clear line of sight) with DVD quality (720x576) video resolution and stereo audio.

Digital wireless

Digital wireless av senders are quickly becoming the most popular solution and combine the use of a system on chip (used for audio and video encoding/decoding) with a means of transmitting the signal, such as spread-spectrum, Wi-Fi and ultra-wideband.

Good news: PAKITE wireless hdmi transmitter and receiver with hdmi jack is coming soon, and the hdmi sender is used for the TV device with hdmi port. Waiting for your inquiry about the wireless hdmi transmitter and receiver.

Should I Upgrade My Car Charger?

The prevalence of smart phones, tablets, GPS units, and other electronic devices in the car—many of them powered via USB—means that having a readily available USB-charging source is a near necessity for many people. If you own a car, it’s worth having a dedicated USB charger that plugs into your car’s 12-volt accessory outlet (aka, the cigarette lighter for older folks).

Even if your car is recent enough to include a USB port for integrating music playback and phone calls with your car stereo, it can still be worth spending money or so for a dedicated charging device in order to get faster charging speeds. That’s because your car’s built-in USB port(s) usually put out only 1 amp of current, which is not enough to charge a tablet or even newer iPhone at full speed. If you’re running an app like Google Maps, using your car’s USB port may not charge your phone any faster than it uses power, so you can end up at your destination with the same battery level as when you got in the car. Even if you were to get full-speed charging from an integrated USB port, most cars have only one such port. It’s worth spending a few bucks to have an always-ready, high-speed charger, especially since it can let you charge two or more devices from a single accessory outlet—your family and friends will appreciate that..

Similarly, if you have a USB charger that you bought a couple years ago, it probably puts out only 1 amp. Upgrading will provide you with faster charge times and the capability to charge tablets and other high-current devices. The same goes if your charger has only a single USB port. We’re living in an multi-device age, so it makes sense to have multiple USB-charging ports.

However, if you just bought a USB charger that provides at least 2 amps from each of its ports, there’s no reason to upgrade. Though you’ll be able to charge your iPad Air slightly faster with our top pick, the difference isn’t big enough to spend more money right now.

  Pakite CU53B series dual USB car charger might be a good choice for you, although it is incredibly small, the revolt dual is not so tiny that it’s difficult to remove. It stood up to every device we threw at it, including multiple iPhones, iPads, a OnePlus One, and a Samsung Galaxy S5, charging each at full speed. Compared to the competition, it offers the best balance of power and price, And the price of this dual port charger is so low that there’s no reason to consider a single-port model.
