  1. Network Switch: A network switch is used to connect multiple IP cameras to the network. It allows for data transmission between the cameras, the NVR, and other devices on the network. A managed switch with PoE capabilities is preferred for powering the IP cameras over Ethernet cables.

  2. Router: A router connects the IP CCTV system to the internet, allowing remote access to the system. It assigns IP addresses to the devices on the network, manages network traffic, and provides firewall protection.

  3. Network Video Recorder (NVR): An NVR receives and stores video data from IP cameras. It allows for remote viewing and playback of recorded footage, and can also be used to manage and configure IP cameras on the network.

  4. Power over Ethernet (PoE) Switch or Injector: A PoE switch or injector is used to provide power to the IP cameras over Ethernet cables. It eliminates the need for separate power cables, simplifies installation, and reduces the cost of wiring.

  5. Network Cables: Network cables, such as Ethernet cables, are used to connect the IP cameras, NVR, and other networking equipment to the network. The length and type of cable required will depend on the distance of transmission and the networking equipment being used.

  6. VMS: Video management software is used to configure and manage the IP CCTV system. It allows for remote access and configuration of the system, as well as monitoring of network performance and camera status.

For bigger facilities:

IDF (Intermediate Distribution Frame) and MDF (Main Distribution Frame) are two types of network rooms that are commonly used in large buildings and organizations.

An IDF is a room or enclosure that is typically located on each floor of a building, and it serves as a central hub for connecting network devices and equipment on that floor or nearby devices. The IDF is responsible for distributing network connections from the MDF to the devices on that floor such as:

  • Computers

  • Phones

  • Printers

  • Wireless access points

  • Other networked devices (like cameras)

The IDF may contain equipment necessary to manage the network connections on that floor:

  • Network switches

  • Routers

  • Patch panels

  • Power supplies

  • Battery backups

An IDF is usually connected to the MDF via high-speed data cabling, such as fiber optic or copper cable.

Pro Tip: IDFs exist because copper network cables (CAT5e, CAT6, etc.) have a distance limitation of 100 meters (328'). They are strategically placed within that distance of devices to be used and then connect to the MDF using fiber optic cable (distance limitations of fiber are multiple miles).

An MDF, on the other hand, is the main hub or nerve center of the entire network. It is typically located in a central location, such as a data center or server room, and it is responsible for connecting all the IDF rooms throughout the building. The MDF may contain things like:

  • Larger network switches

  • Routers

  • Patch panels

  • Power Supplies

  • Battery backups

  • Rack-mounted KVM equipment including a local “clamshell” (monitor, keyboard, mouse in a foldable setup)

It is also responsible for distributing network connections to other external buildings or remote locations. An MDF is usually connected to the outside world via high-speed data cabling, such as fiber optic or copper cable, and it may also connect to internet service providers or other external networks.

Be aware that MDFs usually contain other equipment, not related to the CCTV system, that is of high sensitivity. Never touch equipment that is not contained on one of the racks designated for the CCTV system.
