PHYSICAL NETWORKING:
When planning for your camera system, it is important to take into account how you’re going to get a signal to every camera. There are a couple different ways that we can pass signal from the customers network to our cameras:
SWITCHES:

A network switch (also called switching hub, bridging hub, and, by the IEEE, MAC bridge) is networking hardware that connects devices on a computer networkby using packet switchingtoreceive and forward data tothe destination device. |

We use network switches to separate different areas of a facility, different floors, or completely different buildings! Security camera cables are plugged directly into the switch. Most switches use POE (power over ethernet) to push power directly to each camera. Our switches are unique in the way that they push power up to 700 ft. Most switches only push POE the standard 320 ft.**Our Imperial line of NVR’s do not have camera ports, so all Imperial NVR’s require switches** |
...
Switches can either be connected back to the NVR or connected to another switch. When we have multiple switches to be connected back to the NVR, we place a Gig switch between the switches and the recorder. This helps handle the network traffic coming back to the NVR and prevents a bottleneck.
Here we have a 7-story building. All the cameras are running to switches on the 6th, 4th, 2nd, and 1st floors. The cabling from all these switches is run to a gig switch on the first floor and that switch is then cabled to the NVR. The NVR is the only thing that is plugged into the customers' network. This creates a fully autonomous camera network.

UBIQUITI’s (Wireless Backhaul)

- We can also use wireless backhaul to pass signals from an access point to multiple stations. This is called Point to Multi-point (P2MP). We use a more robust antenna in this situation that can carry signal a longer range in a wider field of view.
NEMA ENCLOSURES: Depending whether the client has available power inside their building, we utilize NEMA Enclosures to house network equipment needed for a Ubiquiti Wireless antenna. Inside a NEMA Enclosure, you could find a switch, wattbox, or even an NVR. THE CUSTOMER IS RESPONSIBLE FOR BRINGING POWER TO THE NEMA ENCLOSURE. It is important to determine the need for NEMA enclosures when you are planning your security camera network.
