1.2.2  Video Processing Unit (VPU)

The VPU is the workstation that processes the video data that is input from the CHU. The VPU stitches the video from all four cameras into a single panoramic view. Then, it applies Pixellot's patented AI auto-tracking algorithms to produce a professional quality broadcast of the sports event for cloud-based distribution to mobile devices and web platforms. The VPU is set up in a secure location at the sports venue, where it is connected by cables to the CHU. During the installation process you will need to connect a monitor, keyboard and mouse to the VPU to setup the initial configuration and internet connection.

1.2.4  Installation Kits (Fixed Installation)

Mount Kit – used for installing the CHU at a fixed (i.e. permanent) location. Includes a Mounting Arm, adapter and pole mount bracket. This kit is required for all fixed installation configurations, including Short Range installation. 

1. Mounting Arm – The mounting arm is used to secure the CHU in place. The arm can be mounted on a wall or it can be attached to a pole using the pole mounting bracket.
   

1. Pole Mounting Bracket – This bracket is used when the CHU is being mounted on a pole. The bracket is secured to the pole using the metal bands. Once the bracket is in place the mounting arm can be attached to the bracket. 
   

1. Metal Bands – These bands are used to attach the pole mounting bracket to the pole. The bands provided are suitable for installation on a pole with a diameter from 3-5". For installation on a pole with a smaller or wider diameter you will need to obtain the appropriate metal bands.
   

1. Adjustable Tilt Adapter – The adjustable tilt adapter is used to connect the CHU to the mounting arm. During installation you will adjust the adapter to find the correct Tilt angle for your CHU deployment location. 
   

1. Safety Cable – This cable is used to connect the CHU to a stable surface as an extra precaution against falling.
   

1.3  Pixellot Prime System - Schematic Diagrams

The following schematic diagrams show the installation setup for each of the three possible configurations for the Prime system. 

1.3.1  Basic Schemes

The basic installation range, upon Coax cables (type RG6) is up to 80 meters (260 feet) from the CHU to the VPU.

Above the basic installation, please refer to installation using Fiber Kit.

This range allows the convenient of installing the CHU in the venue, while the VPU is in the server room, or an office nearby.      

2.0  Surveying the Site

The Prime system is suitable for installation at both indoor and outdoor venues. Prior to ordering the system from Pixellot it is important to survey the site in order to determine which model of the CHU is appropriate for your installation position.
The site survey will also help you to determine what infrastructure preparations must be made to prepare for the installation.
Issues to clarify during the site survey:


1. Precise location of the CHU installation (i.e. height and distance from the court/field). 
   

A precise and final decision needs to be made regarding this issue, since it impacts on which model of the CHU needs to be  ordered from Pixellot.

1. Structural modifications required to accommodate installation of the CHU (e.g. removing obstructions from the line of vision, installing a pole for mounting the CHU, removing obstacles from the path of the cables etc.). 
2. Infrastructure preparations needed for installation of the VPU (AC power, Ethernet).
3. Cable path from the CHU to VPU.
4. Length of cable needed to connect the CHU to the VPU. 
   

2.1  Choosing the CHU's Location

The precise location of the CHU needs to be designated, and the height and distance from the court/field needs to be recorded. These measurements will be used to determine the correct model of the CHU to order from Pixellot. 

The CHU must be positioned at (or near) the midline of the court/field at a distance of between 15 and 195 feet (~5 - 60 m) from the court/field with an unobstructed line of vision of the entire court/field. The CHU can be mounted on any stable surface such as a wall, ceiling or pole. If no suitable mounting surface is available then you will need to construct one, for example by installing a pole in the ground or dropping one down from the ceiling. 

The supporting surface must be capable of supporting a load of at least 33 lb (15 kg).

2.1.1  Requirements

The following are essential requirements for a suitable location for the CHU:

1. At the midline of the court/field (+/- 5%)
2. Distance from the near sideline: 

1. For Full Size fields (e.g. football, soccer etc.): 
   

Min. 25' (~8 m), Max. 195' (~60 m)

1. For Mid-Size fields (e.g. hockey rink): 
   

Min. 20' (~6 m), Max. 180' (~55 m) 

1. For Small fields (e.g. basketball, volleyball etc.): 
   

Min. 15' (~5 m), Max. 80' (~25 m) 

1. Height: Min. 20' (~6 m) , Max. height equal to the distance from the sideline. (i.e. at a distance of 30', the height can be between 20' and 30', and at a distance of 50' the height can be between 20' and 50').
2. An unobstructed path can be prepared for the cables to connect to the VPU.
3. A location that is not an obstacle to and/or danger to the players or spectators.

2.1.2  Recommendations

The following are preferred characteristics for the ideal CHU location: 

1. For outdoor stadiums, the camera should be on the West side of the field facing East (i.e. facing away from the sun during afternoon events)
   
2. The CHU does not obstruct the spectators' view of the court/field
   
3. The CHU is not easily accessible by unauthorized people
   

The blue arrows in the pictures below show examples of good CHU locations:

2.1.3  Mounting Options

The CHU attaches to the Mounting Arm. Pixellot offers a variety of options for installing the Mounting Arm. It can be attached to the wall, ceiling or to a pole. 

2.1.4  Recording the CHU's Location

   Once the precise location has been determined for the installation of the CHU , record the horizontal distance from the court/field in the Site Survey Form. Record the height. And, if there is a need for any infrastructure preparations, record the required preparations (e.g. installing a pole to support the CHU, removing obstructions that block the field of view  etc.)

Note: For medium range installations a junction box must be installed near the CHU. For long range installation JBs containing electrically grounded AC outlets must be installed near both the CHU and VPU.

Make sure that a final decision has been made concerning the CHU location, before submitting your Site Survey. The CHU model that is ordered, based on the Site Survey, may not be appropriate for use in a different location.

2.2  Choosing the VPU Location

The VPU must be set up in a dry, secure location that is not exposed to moisture, direct sunlight or impact from external objects (e.g. people, balls, animals etc.). The preferred solution is to set up the VPU in an enclosed room such as an office or utility room. If no such location is available, consult your Pixellot Support Representative for guidance in creating a dedicated enclosure to house the VPU. 

The VPU location must conform to the following requirements:

1. Inside an enclosure that provides protection from moisture, direct sunlight, extreme heat or cold, collision of people or objects, access of unauthorized personnel 
2. Located within 260 feet (~80 m) cable length of the CHU (based on the planned cable route). 
 
Note: If your installation requires setting up the VPU at a greater distance, speak with your Pixellot Support Agent to find out about additional long range (Fiber Kit Solution) options.

3. An unobstructed path is available for the cables to connect the VPU to the CHU.
4. Access to an AC power outlet with electrical grounding at the VPU location.
5. Access to an internet connection with an upload speed of 5 Mbps or better at the VPU location.
   

2.2.1  Recording the VPU Location

Once the VPU installation location has been determined, record a description of the location (e.g. utility room, cabinet, administrative office) in Site Survey Form. Record any required infrastructure preparations (including installing AC outlets and Internet access). 

2.3  Choosing the Cable Route

You need to determine the path through which the cables will pass in order to connect the CHU to the VPU. This will enable you to determine the precise cable length needed to connect the CHU to the VPU. The cable length affects which (if any) range extension kits are needed as well as the length of the actual cables and conduits that will be used.

Choose the route using the following guidelines: 

1. Ensure that the cables and their conduits do not obstruct movement of players or spectators.
2. If the cables will run along the floor/ground, make sure that they are below ground or flush with the ground so that they don't pose a tripping hazard.
3. Make sure that all cables are either encased in a conduit/tubing or are firmly attached to the wall/ceiling/ground along the entire route.
   

2.4  Preparing IT Requirements

Check with your venue’s IT department to ensure streaming will be allowed through the network and make sure that the following ports are open:

Port #          Protocols

123                  TCP

443                  TCP,UDP

2088                UDP

In the Site Survey Form, record whether or not the required ports are opened.

3.0  Installation

3.1   CoaxPress Infrastructure

Pixellot cables and connectors specs, can be found in section 3.2 below. 

The system performance is affected from using different infrastructure specs. 

3.2  Coaxpress cable specification – Pixellot Prime

Pixellot coaxpress infrastructure is based on coaxial cable, type RG-6.

The connectors are BNC male, 75 Ohm.

1. In order to get the maximum performance, the cables should be similar to BELDEN 1694A cable (GEPCO VSD2001, Amphenol SH-RG-6U SDI).
2. At outdoor sites, the installation should be performed with suitable conduit to prevent weather damage of the cables.
3. Minimum cable specs: 75 Ohm SDI Coax, RG-6, 18 AWG Solid Bare Copper Conductor, PE Insulation, Foil + 95% Tinned Copper Braid Shield, PVC Jacket. 

Connectors:

Pixellot supplies suitable Amphnol BNC 75 Ohm connectors - 031-71065, for infrastructure cables termination.

Pixellot supplies a crimping tool for best crimping performance.

Crimping process should be carried out by a certified technician.

3.2.1   Pre-Installation Check

We recommend that you will do a basic test with the system, connected with the equipment supplied by Pixellot.

This test will be an acceptance test, to verify to system isn’t damaged along the way.

A. Connect the short Coax jumpers to the CHU harness using 4 Female to female connectors.

B. Connect the jumpers to the VPU, to the 4 HD-BNC connectors on the frame grabber.

C. Make sure all BNC types connectors, are locked and tight on the locking position.

D. Connect the audio RJ45, and to the Behringer device using the Y cable. You can see and hear the audio levels with headphones on the device.

FIGURE - COAX CABLES CONNECTING TO THE VPU. ALL CAMERAS ARE GREEN AFTER PAIRING

E.  Operate the system and do a Pairing procedure, to see that the system is working, this procedure is should take some time.

The pre installation test, is the same configuration as on site. Using Coax cables, type RG6 for the cameras, and CAT6FTP cable for the Audio, the distance between the CHU and VPU can be extended up to 260 feet (80 meters). The cables should be installed in designated conduit and junction box, to extend the equipment lifetime

3.3  CoaxPress connections and crimping

On site, the RG6 cables and BNC connectors are the installation infrastructure that extends the CHU from the Coax jumpers and VPU (as seen and the scheme above)

Pixellot provide BNC 75Ohms connectors, and a suitable crimper tool for crimping the connectors on the RG6 cable.

We recommend that this process will be done by an experience technician, for the best result. 

Cutting the cable in the right tolerance and crimping the cable properly:

A. Cutting – best method is using a Coax cable cutting tool (not provided)

See the cutting measurements according to the connector’s length:

                  

B. Crimping – use the supplied crimping tool, that suits best the supplied connectors.

C. Audio cables:

The audio cables will be connected with a CAT6 FTP Ethernet cable, along with the coax cables.

3.4  Installing the Mounting Arm

Secure the mounting arm in place at the location that you chose for placement of the CHU during the Site Survey - Choosing the CHU Location  - section ‎2.4.  If the surface on which the mounting arm will be installed is not yet in place then begin by constructing the surface in the desired location. The mounting arm can be attached directly to the wall or ceiling or to a pole using the pole mounting bracket. 

Make sure that the infrastructure is strong enough to support a 33 lb (15 Kg) load. 

3.4.1  Wall Installation
