NVR Vs DVR

 

DVRS ARE TYPICALLY USED WITH ANALOG CAMERAS. ANALOG CAMERAS TRANSMIT A RAW VIDEO SIGNAL TO THE DVR OVER COAXIAL CABLES.

THE DVR THEN CONVERTS THE ANALOG SIGNAL TO A DIGITAL FORMAT THAT CAN BE STORED AND VIEWED REMOTELY.

NVRS ARE TYPICALLY USED WITH IP CAMERAS. IP CAMERAS ENCODE AND PROCESS VIDEO DATA AT THE CAMERA LEVEL, BEFORE TRANSMITTING IT TO THE NVR OVER AN ETHERNET CABLE OR WIRELESSLY.

THE NVR THEN STORES AND VIEWS THE VIDEO DATA.

HIGHEST RESOULATION NVR MODULE

HIKVISION DS-96624NI-I24H NVR: SUPPORTS UP TO 24 CHANNELS OF 4K ULTRA HD RESOLUTION.

DAHUA DH-NVR7208-16P-4KS2 NVR: SUPPORTS UP TO 16 CHANNELS OF 4K ULTRA HD RESOLUTION.

UNV NVR5208E-4K NVR: SUPPORTS UP TO 8 CHANNELS OF 4K ULTRA HD RESOLUTION.

TCP/IP MODEL

  HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...

Types Of Attack in Network

Common Network Attacks Explained. 1. Overwhelming a Network (DoS/DDoS): Imagine a restaurant that's flooded with too many customers. In a DoS/DDoS attack: A website is overwhelmed with too much traffic. 2. Eavesdropping on Conversations (MitM): Imagine someone listening in on your phone call. In a MitM attack: An attacker listens to your online conversations. 3. Tricking You (Phishing): Imagine receiving a fake email from your bank. In phishing: Attackers try to trick you into giving them your personal information. 4. Finding a Weakness in a Website (SQL Injection): Imagine finding a hole in a fence. In an SQL injection attack: An attacker finds a weakness in a website to steal or change data. 5. Planting a Hidden Camera (XSS): Imagine someone hiding a camera in a party. In an XSS attack: An attacker hides harmful code on a website to spy on you. 6. Guessing Your Password (Password Attck): Imagine trying to guess a friend's password. In a pas...

THE APPLICATION LAYER IS USED BY END-USER SOFTWARE SUCH AS WEB BROWSERS AND EMAIL CLIENTS.  IT PROVIDES PROTOCOLS THAT ALLOW SOFTWARE TO SEND AND RECEIVE INFORMATION AND PRESENT MEANINGFUL DATA TO USERS. 2.  IT SENDS ITS DATA TO THE FORM OF THE  PDU.

MANY DEVICES USE IT AT THE APPLICATION LAYER. PROTOCOLS FTP  (FILE TRANSOFER PROTOCOL) DNS (DOMA...
