Camaras de Seguridad Inalambricas

¿Qué es una cámara de seguridad inalámbrica?

Las cámaras de seguridad inalámbricas son una combinación cámara, transmisor, dentro de un solo equipo. La cámara de seguridad inalámbrica transmite la señal de video a un receptor, y este a su vez esta connectado a un sistema de vigilancia como por ejemplo a un grabador de video digital DVR (Digital Video Recorder)por sus siglas en ingles o simplemente a un estandar televisor en tu casa u oficina. (conectado directamante a un televisor y no a un grabador no podras realizar un playback para observar lo ocurrido minutos u horas antes de tu llegada o cuando ocurrio un suceso importante que desearias ver de Nuevo).
Las formas y tamaños de las camaras de seguridad inalambricas, son diversas y tienen igual function que las camaras de seguridad por cables ,la ventaja es que no necesitas tirar cables y que son super faciles de instalar.

¿Puedo convertir una camara normal en camara inalambrica?

Claro que si,ubicando un trasmisor en la salida de video de una camara regular y su correspondiente recibidor en la entrada de un canal del sistema de DVR que estemos utilizando para el sistema de seguridad.

¿Que tipo de antenna debo de usar para mayor recepcion y calidad de imagen?

Las antennas uni-direccional son las recomendadas para la mayoría de las instalaciones con sistemas inalambricos que estaran a mas de 500ft de distancia este tipo de antennas envian o reciben la señal de radio en todas direcciones (siempre que sea posible trate de que las dos antennas la del transmisor y la del receptor se vean unas a otras).

Las cámaras inalámbricas son capaces de transmitir a diferentes distancias. Dependiendo en gran medida de la linea de vision que sale desde el transmisor hasta el recibidor. La señal puede ser transmitida a través de la mayoría de objetos sólidos incluyendo vidrio, plástico, madera, fibra de vidrio y algunos metales. Por lo tanto, el rango real de transmisión depende del número y tipo de objetos por donde la señal de video inalambrica tenga que atravesar ejemplo de esto paredes de ladrillo, muros de concreto, árboles, letreros de carrereras, etc que tendran un rango de unos 700 pies. Por lo general una cámara inalambrica puede transmitir la señal a través de alrededor de 6 paredes interiores con rangos de hasta a 300 pies y está diseñado para trabajar cómodamente en un edificio de hasta 6,000 pies cuadrados (casa u oficina).

¿Cuál es la diferencia entre las distintas frecuencias?

La mayoría de las cámaras de seguridad inalambricas funcionan sobre una frecuencia de 2.4 GHz, al igual que los teléfonos inalámbricos(cosa esta que provoca un poco de interferencia) Hay otras tres frecuencias: 1.2 GHz, 900 MHz, 5.8 GHz, y a continuacion vamos a ver las diferencias entre ellas :
Una camara de seguridad inalambrica 2.4 GHz, viene equipada con 4 canales seleccionables esto quiere decir que podemos cambiar la camara a 4 frecuencias diferentes buscando la mejor calidad de transmission/recepcion de audio y video.Se recomienda 2.4 GHz más de 900 MHz ya que la calidad de video de esta es major y 2.4 Ghz aumenta la capacidad de rango de los 200 a los 700 metros, dependiendo de las condiciones ambientales.

La señal generada por una cámara inalámbrica de 2.4 GHz puede ser (pero no siempre)interrumpidas por el teléfono inalámbrico de su casa si este esta trabajando tambien con RF 2.4 GHz. Si a usted se le esta creando interferencia en las camaras y no está seguro de si su teléfono inalámbrico o de cualquier otro sistema de 2.4 GHz en tu casa u oficina inalámbrica interfiere la cámara, puede desconectar el teléfono inalambrico, el microwave(que opera en esta frecuencia tambien) o cuanquier otro equipo inalambrico para determinar si ese es el problema.

Lo Nuevo en tecnologia inalambrica de seguridad

5.8 GHz es la última y mejor tecnologia en circuito cerrado de televisión inalámbrico para equipos de seguridad. Grabar y ver hasta 4 canales de vídeo con una frecuencia de funcionamiento entre 5645 ~ 5945 (4 canales), con un rango de hasta 300 pies con línea directa de visión.
Cuando utilizamos la frecuencia 5.8 GHz no estámos compartiendo
ni compitiendo con una frecuencia de radio que se considera banda de frecuencia publica como pasa con la frecuencia 2.4Ghz, por lo que queda eliminado el factor interferencias. Por otra parte, las camaras de seguridad inalambricas con frecuencia de 2.4 Ghz sólo pueden transmitir una señal inalámbrica de hasta 500 pies en linea despejada, mientras que una de 5.8 GHz, envía una señal de hasta 2,000 metros en linea despejada. nos vemos la proxima semana con articulos nuevos y de gran interes.

Mexico City expects a 40% lower crime with video cameras

The government of Mexico hopes to reduce DC in at least 40 percent in crime in the most violent areas of the city, with a network of more than 8,000 new video cameras that will begin to be installed this year.

In the capital, where insecurity is a major problem, there were 122 homicides and 316 sexual crimes and robberies were reported during February 7487, especially against vehicles and pedestrians.

The figures, which are slightly higher than February 2008, are part of a register of the local prosecutor, but independent suggest that the number of unreported crimes is higher.


Installing video cameras
In the three years following 8088 will be placed video cameras at strategic locations such as schools, hospitals, embassies, especially in areas of high incidence of crime, according to the so-called Safe City Bicentennial Project.

3000 The first cameras were installed in the capital from May to begin operating later this year. All cameras will be operational in the second half of 2011.

"With the placement of cameras the city is safer," said the coordinator of the Safe City project, Fausto García Lugo, in an interview. "Patterns of crime in the cities to implement similar programs to reduce video surveillance make a 40 per cent, but may reach 50 or 60 percent," he added.

Part of the cameras, a project in which Telmex, the largest fixed telephony in Mexico, will be the main provider, will be mounted on poles that have a panic button and a loudspeaker so that citizens can report crimes to the authorities in a more agile.

Surveillance and security
He indicated that in July 2011 will also start operating four small robots, unmanned helicopters that carry video cameras to monitor emergencies from the air.

Besides the more than 8,000 monitoring devices, the Metro is placing cameras in their 3000 platform and facilities to monitor any criminal acts or emergencies, he added.

Until now, most of the 400 video cameras installed in the capital, nearly 20 million people whereas the metropolitan area have been used to observe or follow road conflict manifestations.

The project involves a series of Bicentennial celebrations next year, when the criteria of 200 years of independence, in addition to major road works.

My WebSite automatic adjust Diferent Resolution screen

Almost all pages are optimized for a resolution of only 800 x 600 pixels, and while most teams are now set to that resolution, the older monitors do not support more than 640 x 480 pixels, on the contrary, the teams last generation have often set the monitor to 1024 x 768 pixels and can support up to 1280 x 1024.

The optimization of only one page at a resolution of 800 x 600 pixels, it can even be more than annoying for monitors 640 x 480 pixels, and even impossible when the navigation option to disable scroll in web page developed using frames.

To solve this problem there is a possibility, although some what laborious, it is worthwhile as it gives you an optimized website for all the resolutions that are desired. It is very important for a good organization from the beginning.

The structure of the folders if appropriate, as explained below, will save a lot of work because it will avoid having to rename files, edit links and images that repeat unnecessarily increase the size of the site with the consequent loss of time to upload.

This would recommend the following steps:

1. Create a main folder where the site is hosted eg "MyWeb"
2. MyWeb create within a folder named "images" where the images are, another one called "sounds" where the sounds, videos and so on according to the resources used. Then you create a folder called es800600. The last folder contains only files htm, php, cgi website to be created with a screen resolution of 800 x 600 pixels.
3. They create two folders called es640480 and es1024768 within "MyWeb"
4. Once you have developed the Web site is optimized for 800x600 and is now the definitive version, it copies the contents of the folder and pasted es800600 within es640480 and es1024768.
5. Changing the monitor settings to 640x480 and open the files in the folder es64048 only be re-edited, is primarily a work setting tables. NO NEED TO CHANGE OR RENAME THE FILE LINK.
6. Likewise, changing the monitor to 1024x768 and htm files are opened that fall, edited and saved.
7. If you want to create a version in English only should be copied the three folders that begin with the letters "en", rename the start by "at" and replace the text by the English, but the images will not have to re-upload or change the links or file names.
8. Create the main page that is within "MyWeb" and outside of the above folders. This main file, index.html should contain the following code in the body... to see the code please visit http://www.drpcsolution.com/37-camaras-ip

- How can I cut the annoying windows that I open when I'm alone on the internet?
The problem is that they are infected with some type of parasite called Spyware. But after reading this tutorial carefully, download and update the tools shown below, their problems will be solved.

What is Spyware?

Spyware has some similarity with the virus, but unlike these the spyware is not malicious code to our PC. Hence the common Anti-Virus can not recognize or deleted.
Spyware are small programs that are installed in our system with the purpose of stealing our data and spy our movements through the network. Then send that information to Internet advertising companies to market with our data. Working mode 'background' (background) so that we do not realize that they are starting to appear until the first symptoms.

How do they enter our PCs?

1. When visiting websites that we download malicious code (ActiveX, Cookies or JavaScripts) without our consent.
2. Following a call by a virus or trojan
3. Being hidden in a free (Freeware) who accept the conditions of use (almost always in English and not read) we are agreeing to comply with his duties as spies.

What information can we draw? They may have access to eg: Your e-mail and password, IP and DNS address, telephone number, country, pages you visit and which topics interest you, that in these times and how often they return, which have and which software downloads to do shopping on the internet and more important as your credit card and bank accounts.

What are the most common Spyware?

AdSofware, Alexa, Cydoors, Gator, Web3000, Webhancer, CoolWebSearch, BlazeFind.Bridge, Xupiter, HotBar, Kazaa etc. ....

The 5 main symptoms of infection.

1. We only change the start page, search and error in the browser.
2. We open windows pop-ups everywhere, even offline and without having the browser open, the majority of items are pornographic.
3. Bar search sites such as Alexa, HotBar, etc. .. we can not remove.
4. The buttons that appear in the browser toolbars and can not remove.
5. Browsing the network becomes increasingly slow.
