Configurazione APN per i maggiori operatori presenti in Italia

Di seguito gli apn degli operatori più conosciuti:
N.B. (vi consigliamo, comunque, di verificare sulla pagina internet dell'operatore mobile o contattando il relativo call center al fine di accertarvi del corretto APN da utilizzare per la vostra specifica offerta, in quanto alcuni operatori potrebbero applicare costi differenti se utilizzate l'APN sbagliato)

VIDEOSORVEGLIANZA COME FUNZIONA E QUALI SONO I VANTAGGI DEL P2P?

P2P è la forma abbreviata di Peer to Peer, ossia una rete di computer per lo scambio di file in cui non vi sono server o client fissi.

La tecnologia P2P viene utilizzata in molti campi che offrono la condivisione di media o file attraverso Intenet senza bisogno di sottoscrivere servizi DDNS, né di programmare la mappatura delle porte del router. 

Skype, uno dei più famosi software di video comunicazione , utilizza la tecnologia P2P per fornire una soluzione VOIP. Poichè non esiste un server per consentire l'archiviazione o la distribuzione di file, i terminali P2P possono comunicare tra di loro e condividere file senza l'utilizzo di server.

A causa delle limitazioni di rete, le telecamere IP erano limitate nella trasmissione di rete in LAN e le vecchie tecnologie non consentivano alle telecamere IP di essere accessibili via Internet. Per risolvere questo inconveniente, l'informatica si è armata di nuove tecnologie come i DNS dinamici (DDNS), protocolli SIP e altro ancora. 

I DDNS consentono agli utenti di accedere alle telecamere IP che utilizzano un indirizzo IP dinamico, ma se utilizziamo tecnologie tradizionali (RTSP / RTP) non possiamo trasmettere il flusso del video su internet (WAN),quindi abbiamo bisogno di utilizzare la tecnologia P2P.

Le telecamere IP tradizionali richiedono all'utente di impostare la rete per un utilizzo corretto delle telecamere , inoltre, per il controllo remoto, l'utente avrà a che fare con porte e impostazioni del DDNS. La tecnologia P2P permette alla telecamera IP di penetrare automaticamente nel firewall di rete e ottenere l'indirizzo IP stesso, il che significa eliminare le impostazioni di rete ed eliminare il server.

Quindi:

Non c'è bisogno di server o di servizi DDNS
Non c'è bisogno di impostare o mappare delle porte
Possibilità di connettersi alle telecamere tramite internet da qualsiasi luogo
Protegge la vostra privacy con streaming video cifrati

Micro Cameras


Microcameras (or micro-cameras) are small electronic devices that can record video discreetly without emitting any kind of sound or noise. Characterized by low energy consumption, the micro cameras can be able to record audio and video in complete autonomy, or intended to be connected to traditional video surveillance systems.
Concealed microcameras.
Microcameras with an integrated audio / video recording system can be easily hidden to defend themselves against vandalism or to carry out events inside their homes. In fact, the micro-cameras mount lenses and lenses with very small dimensions that allow you to resume what is happening in an environment through a hole of a few millimeters.
Video and DVR microrecorders.
The term DVR refers to the English acronym Digital Video Recorder (digital video recorder), this device can be of various sizes and use different memory media depending on the use to which it is intended.
In traditional video surveillance systems, for example, large DVRs (equipped with cooling systems composed of fans and heat sinks) are used in which a hard disk is inserted for storing the shots.
For filming for investigative use, on the contrary, very small DVRs (called for this reason also Mini DVR) are used to store the video taken by the micro-cameras connected to it on small memory cards (SD Card or Micro SD Card).

Micro voice recorders


Audio microrecorders (or spy recorders) are tiny voice recorders that can record sounds and conversations in the environment in which they are placed.
Main differences between microregistrators and voice recorders.
The microrecorders (or recording bugs) are distinguished from the common voice recorders for different aspects, the main ones are:
- the very small size of the microrecorders compared to traditional audio recorders.
- the reduced energy consumption of the components that allows these audio microrecorders to have very long autonomy during recording.
- the high quality audio that allows these microrecorders to capture voices, sounds and conversations inside entire environments (and not just a few centimeters from the interlocutor as it happens for common voice recorders).
Spy microphones and audio quality.
All the professional micro-recorders that you can find on the Microspie-GPS site, are equipped with powerful spy microphones of the best manufacturers (Sennheiser, Sonion, Knowless and others) that guarantee our products a high quality audio.
This together with specific functions designed for private investigation (VOX voice activation system, automatic AGC gain control, ease of installation and use, etc.) ensures that our micro-recorders adapt perfectly to the environment in which they are placed, making them perfect for use with car microrecorders or microrecorders for environments.
Functions of the micro-recorders for investigations.
Another factor that distinguishes the microregistratori for investigations (also known as recording bugs) from voice recorders are the advanced features that they offer, in fact in addition to the high sensitivity of the audio products intended for investigation depending on the model can offer the functions important as for example:
- VOX voice activation system (which allows the microrecorder to activate only when the microphone hears voices and conversations). This function offers advantages both for the micro recorder itself, which thanks to this function, will be able to save memory and reduce energy consumption, both for the user and thanks to the VOX voice activation system will be able to listen to the recordings made more quickly and incisive.

How do GPS work?


Satellite trackers (also known as GPS trackers, bug-gps and gps bugs) are produced to indicate the exact location of the object or vehicle on which they are applied.
GPS trackers can be used in different areas and for different purposes such as:
- indicate the exact position of a valuable merchandise during transport (gps tracker locator for shipments).
- indicate the position of a vehicle in the event of theft (anti-theft GPS locators).
- indicate the movements made by a vehicle in real time and / or review the history of the routes and stops made (gps locator for investigations).
Use GPS trackers for investigative services.
The GPS trackers for investigations (or GPS / bugs gps bugs), are small products equipped with battery operated magnet to indicate the position of the vehicle on which they are applied in complete autonomy.
In fact, in order to apply the investigative gps locators, unlike what happens for gps anti-theft locators, it is not necessary to make any connection to the current of the machine on which they are placed.
For this reason gps bugs in recent years have become widespread in the investigative sector, as demonstrated by recent surveys that indicate that 88% of investigative agencies in the country use GPS bugs during their investigative services, to the detriment of 12% who declare not to use or own any type of GPS tracker.
