STREAMING SOUND ON THE MEDIA PLAYER

Sound information transmitted from the IP microphone can be heard on the media player, which supports broadcasting via the RTSP protocol. Let's take a look at the application of the broadcast on the application of the VLC media player.

Launch the VLC media player.

Go to "Tools - Settings - Water / codecs", drop to the very bottom of the page and check the box "RTP over RTSP (TCP)" and close this tab (look at the little ones below).

Then select the item "Media - Open URL" and specify the address of the Dzherel signal (IP of the OCA P1LN microphone) using the rtsp protocol. Marvel at the butt at the little one below.

After entering the address, it is necessary to press the button "REVIEW". The media player connects to the IP microphone and broadcasts the audio stream. Thickness is restored individually.

In the broadcast mode, the audio stream can display statistics and check, which flow of data can be found and with which speed. For this, you need to go to the "Tools" menu and select the "Information about the media file" tab. Go to the "Statistics" tab. Seen at the end, as shown in the little one below.

When you go to the "Codec" tab, you can select a codec for your IP microphone in present moment time is the sampling rate.

The broadcast mode is implemented on the VLC media player installed on any phone or computer. The VLC media player program can be downloaded free of charge in the Android Market (for Android phones) or in App Store(For iPhone).

Audio warning has long become a parable like in Russia, so it is behind the cordon, and the history of yogo dosha and wealth, lower in video warning. Historically, setting it to a new level is more negative, wanting, as if it were a tool, an audio watchful of itself, neutrally and more likely to lie only depending on the one in whose hands it is known. Until the beginning of the era digital technologies it was supposed to be exclusive to the radio, but progress, as you know, do not stand on the floor, and now for a clear transmission to the sound, strike and prost Merezhi Wi-Fi. About microphones, building sound recording over IP, and see this article.

For the first time, let's talk about the relevance of audio warnings for video warnings. There are many people who can get by with cameras without sound (stink, you understand, cheaper than their sound-catching brothers) and are satisfied with this movie. However, the microphone for the camera carried a little vigodi with it: first, the night time is finished and the light is just badly illuminated, as a rule, it is badly indicated on the quality of the video. To learn from the improvement of infra-red lighting to know the camera, build good quality (more measurements) in the darkness, is not an easy task. The sound of the dark does not stream, moreover, in the nighttime, outside noise is significantly less, and the sound expands and catches more quickly. Adding to the video sound support is also significantly more informative - the operator/administrator takes a more detailed picture. So, turn your attention to the position, how to occupy the cameras: in order to maximize the area of ​​\u200b\u200bappointment in the frame, they sound in the corners. There is a cry for superfidelity between optimal sound and optimal video. The sound, being praised by the pressure of the air, generated by the colivans of any object (for example, voice calls), expands like a dzherel in the right directions. The ringing with singing frequency and amplitude captures the sensitive membrane of the microphone, ringing itself and transforming it into a change electric strum different voltages. This is how sound recording works. At this right microphone, great flat surfaces - steles and walls are very much respected: whistle blows over them, superimposed one on one, giving birth to other creations. That’s why it’s a destination - what’s not the most possible for a new position.

Otzhe, an okremy microphone for the camera is absolutely necessary. Where can I get some kind of sound recording device so that I can link Yogo to Xeoma? Not long ago we knew for this food guide: microphones e-ear the production of the company "Electronic shield". It is easy to install these compact, sensitive extensions, like in the house, so the call, otrimuyuchi at which sound high capacity. The kit looks like this:

It’s easy to practice with them - add a module to the lancet "Microphone" and select E-ear from the list:

Zvіdsi we need less serial number- Yogo skopіyuєmo at the top of the field nalashtuvan at Xeoma. Below we know such a division:

In the Service columns, the Addresses of the media service must be specified to the IP address of the Xeoma computer (as a matter of fact, a static IP address is required on the server), the Port of the media service may be specified to be a different port. Let's change the way that Count Vibir's service costs 3 Mediaservice. Xeoma has the following picture:

The number of the sound channel is assigned, which one of the microphones to listen to, you can connect the dekilka to one extension.
All is ready! Connected "Microphone" to the already existing module "Revision and Archives", and the sound recording is archived over the video.

Nasamkinets slid respect for the legal bill of nutrition. І video-, and audio warnings may be directly referred to article 137 of the RF Criminal Code "Destruction of the lack of torment of private life", as it unambiguously indicates the illegality of the collection of information about the private life of an individual no yoga. It is especially important to mark the month of holding such a warning with special signs/tablets.

In this rank, a good microphone for the camera is no longer a luxury, but an amusing investment in your security system.

At the Amphion Forum a few days ago, Ang Cui, a student from the Department of Systems for Designated Intrusion at Columbia University, read an addendum (slide presentation, pdf) on the topic of exploitation of intrusions in the CNU (Cisco Native Unix) core in Cisco IP phones 7975G, 7971 -GE, 7970G, 7965G, 7962G, 7961G, 7961G-GE, 7945G, 7942G, 7941G, 7941G-GE, 7931G, 7911G, 7906, 7971G-7 .

The strife of the CNU is somewhat similar to the one that was recently revealed, which gives access to the physical memory of the annex with an addendum with the rights of a coristuva. At to this particular type It is possible through the lack of security checks in the syscall function. In this way, the attacker takes away the ability to rewrite enough fragments of the kernel memory and run it on the code.

Ang Kuї not only describing the inconsistency, but demonstrating in practice how it is possible to operate, for example, for converting a Cisco IP phone on an attached attachment, which is not audible for a koristuvach. The slippery code denies root rights in the system, denies access to the digital signal processor (DSP) and the control interface of the add-on. The student has developed a patch, which changes the necessary changes in the core of the DSP, so that the IP-phone is not remembered for the spy, turn on the microphone and begin to attach the listening to that record.

Pod hour svogo vstupu Ang Kui showing how best to install such a patch on any IP-phone. For which you need to work a small microcircuit with a different firmware, insert it into the phone's Ethernet port - and it's off in a second. After that, the phone can be "reflashed" and it can be done as a "bug" and recording all the necessary sounds. You can install the patch remotely, via the Internet, if you want to report some zusil to someone by running the file. Zavdyaki inconsistency CNU be-yak program can take away the rights of the root.

Ang Kuї having also revealed a lot of libraries from third-party retailers on Cisco phones, in which they are also different for operation. Vikoristovuyuchi їх, you can try to install shkidly code to attach to the place without moving the coristuvach. Meanwhile, I have not yet seen information about contention in third-party libraries of Ang Kui, having announced the disclosure at the 29C3 conference (29th Chaos Communication Congress), as it will be held from 27 to 30 December in Hamburg.

The Cisco company was ahead of the influx and 2 more leaf fall released a new patch for some phone models (div. bug CSCuc83860). This patch is recommended to be installed to all corristuvachas, as it is clear, the exploit shards are already available open access. Tsіkavo, what the doslednik could not know in the Internet files new firmware telephones, tobto and the owners of devices, you can’t just download them so easily. It’s easy, it’s necessary to go straight to the foreman.

For other models - zocrema, 7971G-GE, 7970G, 7961G, 7961G-GE, 7941G, 7941G-GE and 7906 - no patches have been issued, phone numbers have been taken from selection. Owners of such devices are recommended to buy a new model.

Razlivіstvo in IP-phones Ang Kui having seen the process of work on the initial project Gunman v2, within the framework of such a stench, a firmware update for tether printer HP has a great document. After processing such a document, an exploit penetrates the firmware and instantly expands the shkidlivy code on the computer at the local network. In the words of the reporter, at the same time, more framing outbuildings - such as printers and IP-telephones - may be frivolous and become a threat to the safety of local framing.

Ang Kuї zgaduє іstorіyu rіchnoї prescription, if deyakі nevіdomі hackers penetrated into the SCADA-system of the water supply of one of the American cities and disturbed the water pump, leaving the townsmen with drinking water.

On іlustration to tsієї novina you can use a known model of IP-telephone.

Life is not foreshadowed, and this is sometimes blamed on situations, in case of any need in the distance, that secretly eavesdropping place, like roses on the streets in other places. Without looking at the moral side of food, let's look at the fundamental foundations of listening to the audience. Yaki technical outbuildings allow tse robiti? What are the specialties? What do you need to know for someone who has heard the eavesdropping on the screen? - on qі and іnshі nutrition you will know vіdpovіdі at tsmu small look.

Listening on the screen - the theoretical side of nutrition

Іsnuє kіlka ways zdіysnyuvati vіddalene ta secretly eavesdropping:

• Perekhoplennya sound whil. Without delving into physics, it is significant: the sound is repeated by mechanical columbs, as it can be captured by a special attachment - a microphone.
• Calling again and again calling out also vibratsiyu z sound frequency physical objects: a warehouse, a wall, some other surface, and to that, having taken the sound of the objects themselves, you can also take away the sound “picture” of the extra space. This particularity is the basis for the work of a special listening device with a winder.
• Another way, vіn pіdіyde іlki tіlki for eavesdropping rozmovі people - posіrіgat behind rukhami lips, scho to speak z one-hour translation.

Tse everything, vіdomі at the current moment, ways of that secret eavesdropping. Let us not look around at the possibility of reading lips and understanding the chiselling from the surface of objects. The first of the designated methods is supra-twisted, the shards will require a special type of beginner, and the other is a special kind of expensive, folding equipment.

Yak pratsyuє possession for eavesdropping on the vіdstanі

Today, you can buy an audition at a railway station in Moscow and other places without any problems, so let's figure out how to use this kind of equipment.

You can listen to the sound in the distance in the following ways:

• Put the “bug” in front of the space and move the transmission signal of the wire line to the radio channel on the receiver, listen to the next one and (chi) record the sound;
• Install a radio-transmitting microphone on people or a dog, and the stench, if required, hangs on the floor, deafening conversation;
• In advance, it is attached to install a sound recording attachment (dictaphone) at the misc, de sound the dialogue for you, and after taking it, listen to the recording;
• For help special outbuildings- mikrofonіv sryamovanoї dії, eavesdrop and (or) record the chatter of the conversation in the distance.
• In order to listen, put a sensitive microphone on the walls of a special kind, like a stethoscope.

Let's take a look at the deeds from the designated methods of the report, but at the same time: the directing radio microphone. The two options themselves have gained the largest width in practice.

Radio microphone as an attachment for listening on the screen

The most wide-ranging way is to install a miniature "bug" with a special microphone and protect the signal from the distance. Vykoristannya provіdnoї іnії іnії іn transmission і signal vikoristovuєtsya seldom: it's necessary to pull the wire, it's impossible to hide it. The most popular among them is GSM mini eavesdropping, as it transmits the signal through channels style tie, so through them you can hear Rozmov in any point of the world, vikoristovuyuchi splendid mobile phone

Let's take a practical look at the features of such an attachment, one of them.

The GSM is presented to the vidstani, bugs buy it is possible for the cinema, and that is the function of permitting the perch to the rosary of the profession, we can vistitati at the roli, so Ikhiy, so for Monitoric. mist. The extension has two modes: the ability to raise the voice, with the advancing call to the front of the tasks stylish phone, as well as the mode of non-stop listening.

The radius of the microphone to become 10 meters, and the size of the attachment (40 * 30 * 10 mm with a vase of 24 grams) allows you to grab it in any place: bag, odyaz, in the middle of the "glove compartment" of the car, and in the adjoining place, attach it so you know the bug itself will be practically impossible.

An hour of work in the presence of a fully charged battery in the listening mode for up to three years, and in the alarm mode - for two to four days - all lie down in the amount of time to call and dial the number. In recovery mode, with a fully charged battery, it is guaranteed to work for three to five days.

For a call to a bug, a vicorist channel of a stylistic call is in the range of 900, 1800 and 1900 MHz, so it will be popular in our country.

The range of working temperatures is from minus forty to plus fifty degrees Celsius, so that the robot can be used in both opalous and non-malignant environments, as well as outdoors. The head of the mind is a stable stylist's lace.

A lot of installation organizations stick together because one single active microphone, navit with the main characteristics, often does not fit into the hearing of an acoustically foldable premises or a large hall.
For the great bays, the obvious solution is to increase the quality of listening to all areas will be more than a few microphones. At this point, the microphones are due to roar so that their zone of sensitivity covered the entire area of ​​the premises and often overlapped with each other. And then further supply the connection of these microphones to the video camera or audio recorder.
The simplet -to -the -west of the macrophonev for one Audiovkhіd give out the result, so the yak at the TSOMU to the parameters of the LINII (єmnist, OPIR, illettic) і, iv, the progirhenna of the Audi -Lyuba, and in the moment of the signals of the mirophics, will be in turned on. from one screeching sound failed the sound on the record.

Mixers STELBERRY

In order to combine that summation of audio signals from different jacks in sound recording studios, audio mixers of various complexity have long been widely used.
But why is it so widely known and unsuitable for audio studios until the end of the hour without taking away such a wide width in the middle of the security and audio-video-watchfulness.
Correct this situation and raise the possibility of security systems to a new level by calling the models of mixers STELBERRY MX-300, STELBERRY MX-310 and STELBERRY MX-320.
The main characteristics of these mixers are the same, but the main characteristics of these mixers are improved in the functionality of the menu, or else, comfort is improved.
The skin from mixers MX-300, MX-310, MX-320 allows you to connect up to four active microphones to your line inputs (and not only active microphones) and to build a skin channel for an equal signal, individually or with other channels.

The MX-300 mixer has its own independent regulation of the signal at the skin channel, so you need to adjust the signal of either a microphone or a different line signal independently to other channels, switch them on physically, switch on the switch.
In the MX-310 mixer, the leather channel is set up separately from other channels, and you can listen to the whole sound picture without leaving the menu.

The MX-320 mixer gives you the ability to independently select, if four or more channels will be active, and work to improve channels, as well as outside the skin channel in others, and in pairs with one or more channels.
The ability of this mixer to quickly change the configuration of the rear channels without any physical connection will be handy, as in any location the furniture is often changed, or the zone of active presence of people is often transferred.

Tsіkava specialty of STELBERRY audio mixers

STELBERRY audio mixers have such a peculiarity that all of these mixers have linear audio inputs and linear audio outputs.
This feature allows you to build up the structure from successively connected audio mixers, including the outputs of some mixers to the inputs of other mixers.

So if one mixer allows you to connect only a few active microphones, then you can connect four mixers, connect to the inputs of the fifth mixer, but still allow you to victorize a cluster of sixteen active microphones.

Choose a microphone for a great destination

As active microphones are the best way to listen to the communication with mixers. To improve the fact that background music can play in the hall, a little ventilation or air conditioning, it’s definitely due to the microphone without AGC (automatic control of power) or AGC, which is included. Only microphones for receiving without AGC allow you to save the versatility of the movie in the minds of various noises. If you want to switch the microphones from the AGC, then the automatic adjustment of the power will be on background noise And to draw it up to the level of the output signal of the microphone, and on the record, there will be no more noise, and the color signal will be crushed.

Listening to old premises and corridors

Acoustically foldable, the premises are themselves sounding vityagnut in the hall or corridors, as well as large empty or empty halls, where the sound is given the opportunity to freely and richly sound through the walls, and the steles. In such places, the optimal placement of microphones will be the best place, or a corridor with a song croc, which should lie in the sensitivity of the selected active microphones with such a mind that there are no deaf zones between the microphones.
For example, in such a long-term placement, when microphones are placed on a stele with a stele height of 2.5-3 meters, the M-20 microphones should be placed approximately 3-4 meters apart, one in one, and the microphones M-60, M-70, with included AGC due to roztashovuvatisya on a distance of approximately 7-8 meters one per one.
At whom the sensitivity of active microphones is increased, those stench of the troch crossed the zone of sensitivity of the suicidal microphones. Microphones with fixing strengths are cheap and cheap, but to give more folding with improved placement, through the need for more accurate selection of the height of your footprint and installation.

Microphones with adjustable sensitivity fit better

Improving the sensitivity of the microphones with small overlaps in the sensitivity zone of the sound microphones will allow minimizing the effect of the loudness of the harrier, as well as avoiding voice failures when people are moved, so to speak, near a corridor.
Later installed microphones are connected to the mixer, for example MX-300. And then, on the mixer, there is a correction of the strength of the skin channel, so that the signals from the microphones are the same for the thickness. And then, for the help of a substitute, the signal from the mixer is sent to an autonomous audio recorder, for example SPRUT-SR, or as a video warning is conducted in the receiver, then to the linear audio input of the video recorder or the linear audio output of the IP camera.
Such a butt of placement of microphones is a little smart, as if mentally selected for a butt of use. In fact, practically, the short and variant of the placement of microphones on the line is chosen experimentally for a skin specific application, and there is no universal “recipe” here, the skin application will have its own aspects, it will require a solution at home.

Listening of trading bays

The trading floor is a classic version of the great hall for listening to such a single microphone is clearly not enough.
Even the staff and clients can freely change their minds, calming their minds for audio recording.
And often, for small shops, the area of ​​\u200b\u200btheir accommodation is not large enough, it is sufficient to accommodate no more than four active microphones M-60, M-70 on the walls or on the stele, which can be connected to one mixer, for example MX-300,
and the combined signal from the mixer output is sent to the line audio input of the stand-alone SPRUT-SR audio recorder.

Placement of microphones near the hall

If the shape is close to a square and the area of ​​application is approximately 250 m² and the height of the beds does not exceed 2.5-3 meters, then it is enough to place a couple of microphones M-60 or M-70, with AGC turned on, closer to the wall on the walls at the points of stitching in the middle of the skin from the walls. For example, the area of ​​​​application with a wall of 2.5-3 meters exceeds 250m2, but not more than 1000m2, then there are enough microphones and one mixer. Microphones M-60, M-70, with included AGC, in this way are placed on the stele at the corners of the virtual square in the center of the hall. Mіzh mikrofonami in usіh directing can be buti vіdstan vіsіm metіv.

Apparently, since you have a larger area and a sufficient number of audio channels, you will have to increase the number of microphones and increase the number of mixers. And if you only have one audio file for registration of roses, then you will have to build up the structure

mixers, if 2-4 mixers come out, they are connected to the inputs of the third-fifth mixer. I’ll reiterate, all the best recommendations. In fact, a short and variant of the placement of microphones can be chosen experimentally for a specific skin application.

Listening to the sector at the majestic trading floor

For even the great trading bays, it is necessary to zone the hall by sectors, depending on the category of goods, and call, one or two managers, or sales consultants, are seen for one such sector, to advise clients and to write goods. And here, in order to control the quality of customer service, it would be good to be a little bit, like a manager or a consultant in this sector, liaising with a client, like a merchandise to promote and promote it to the point.

Build up the structure of the mixers to allow victoring more than four microphones

Racks and display cases with goods can weigh a few dozen meters and in a sector there may be a few rows of such racks.
Obviously, here and in the future it is possible to build up the structure of the mixers, to expand the microphones throughout the entire sector, the shards of one mixer with the microphones do not stick out for listening to the entire sector zone.

Sound like this trade halls may be arched high walls, and the walls can be far away from the placement of a sector with a group of goods, so the most rational option would be the placement of microphones on the floor. The height of the height of the microphone may lie in the height of the racks with the goods. And here you need to understand the fallacy, which is heard by the microphone of the area of ​​​​application, from the height of your height.

Why is the microphone in the middle of the sub-logs, more often than not, the mother will have an active microphone, so that there are no deaf zones between them.
Obviously, with the use of a choti-channel audio recorder, for example SPRUT-SR, it is possible to organize listening to some of these sectors from clusters by choti and microphone in the skin one.
