# Analog cameras

## <span style="color: rgb(0, 0, 0);">When do I need an analog camera?</span>

<span style="color: rgb(0, 0, 0);">Under certain conditions analog cameras will serve you better than digital cameras. If cables longer than 5 m are needed between the camera and recording equipment, for most digital cameras, you need an amplifier. Industrial analog cameras may be more suitable in these cases. Cable lengths of 30-50 meters are generally no problem.</span>

<span style="color: rgb(0, 0, 0);">An additional advantage of analog cameras is that their signals can easily be splitted by simply splitting the cable. To split a signal from a digital camera a video splitter or video splitting software is needed.</span>

## <span style="color: rgb(0, 0, 0);">Install and setup</span>

<span style="color: rgb(0, 0, 0);">To convert the output of analog cameras into a digital format, a video capture card is needed. If you bought a complete solution from Noldus IT, the video capture card is present in the computer. If you bought your cameras, video capture card and MediaRecorder separately, you must do the installation and setup yourself.</span>

# IP cameras

## <span style="color: rgb(0, 0, 0);">When do I need an IP camera?</span>

<span style="color: rgb(0, 0, 0);">IP cameras are connected directly to a network. IP cameras are especially useful to film for example at a remote location and receive the video files through an Ethernet network on your computer.</span>

## <span style="color: rgb(0, 0, 0);">Network requirements</span>

<span style="color: rgb(0, 0, 0);">To use MediaRecorder with IP cameras, the following network requirements apply:</span>

- <span style="color: rgb(0, 0, 0);">An Intel Pro/1000 CT or Intel Pro/1000 PT (1 Gb) network adapter is installed in the computer with MediaRecorder.</span>
- <span style="color: rgb(0, 0, 0);">The cables are suitable for Gigabit Ethernet. The minimum cable quality is CAT5e.</span>

<span style="color: rgb(0, 0, 0);">[See https://en.wikipedia.org/wiki/Category\_5\_cable](https://en.wikipedia.org/wiki/Category_5_cable)</span>

- <span style="color: rgb(0, 0, 0);">We recommend to use a dedicated network.</span>

## <span style="color: rgb(0, 0, 0);">Install and setup</span>

<span style="color: rgb(0, 0, 0);">If you bought a complete solution from Noldus IT, the network adapter is present in the computer, the IP cameras are set up and the MediaRecorder settings are made. If you bought your cameras and MediaRecorder separately, you must do the installation and setup yourself.</span>

- <span style="color: rgb(0, 0, 0);">Axis M1375</span>

## <span style="color: rgb(0, 0, 0);">Cable length</span>

<span style="color: rgb(0, 0, 0);">In theory, for IP devices, a cable length 150 m should be possible. However, it has not been tested by us. We know that a setup with a cable of 1 m and an extension cable of 50 m with a switch between the cables works well with MediaRecorder.</span>

## <span style="color: rgb(0, 0, 0);">Notes</span>

### <span style="color: rgb(0, 0, 0);">ONVIF Profile S</span>

<span style="color: rgb(0, 0, 0);">ONVIF is a communication standard for network devices. ONVIF Profile S applies video and audio streaming and PTZ control. Most IP cameras nowadays support ONVIF Profile S. For cameras that do so, pan, tilt, and zoom control can be done with MediaRecorder and audio from the camera can be recorded. For cameras that do not support ONVIF, pan, tilt, and zoom control must be done with a browser and audio must be recorded with a microphone connected to the sound card of the computer.</span>

### <span style="color: rgb(0, 0, 0);">Power over Ethernet</span>

<span style="color: rgb(0, 0, 0);">IP cameras can be connected to a PoE (Power over Ethernet) or PoE+ switch to supply them with power. This way no extra power cables are needed. Each device is connected to one channel on the switch. A PoE switch can deliver up to 15 Watt per channel. A PoE+ switch has a higher capacity per channel (up to 30 Watt per channel). Make sure that the maximum total capacity of the switch is high enough for all cameras together.</span>

<span style="color: rgb(0, 0, 0);">Example - you connect four cameras that need 30 Watt each to a POE+ switch. This POE+ switch must deliver at least 4 x 30 = 120 Watt.</span>

- <span style="color: rgb(0, 0, 0);">Axis M5525 - requires a regular PoE switch.</span>
- <span style="color: rgb(0, 0, 0);">Axis M5054 - requires a regular PoE Switch.</span>
- <span style="color: rgb(0, 0, 0);">Axis P1375 - requires a regular PoE switch.</span>

<span style="color: rgb(0, 0, 0);">The PoE or PoE+ switch must allow a speed of at least 1 Gb per second.</span>

# Important notes about USB

## <span style="color: rgb(52, 73, 94);">USB 2 and 3 ports</span>

<span style="color: rgb(52, 73, 94);">The supported USB devices are all USB 3 devices and need to be connected to a USB 3 port. You recognize USB 3 ports by a double-S in front of the USB icon. Some USB 3 ports and connectors have blue labeling. </span>

<span style="color: rgb(52, 73, 94);">[![image.png](https://bookstack.noldus.com/uploads/images/gallery/2023-11/scaled-1680-/FJqfoqjtBkmvXvJY-image.png)](https://bookstack.noldus.com/uploads/images/gallery/2023-11/FJqfoqjtBkmvXvJY-image.png)</span>

<span style="color: rgb(52, 73, 94);">The Dell Precision T3640 desktop PC sold by Noldus IT has both USB 2 and USB 3 ports. The Dell Precision 3551 mobile workstation only has USB 3 ports.</span>

## <span style="color: rgb(52, 73, 94);">USB hub</span>

<span style="color: rgb(52, 73, 94);">Do not connect your cameras to a USB hub. If you run short of USB connections, connect your license key, keyboard or mouse to a USB hub and connect your USB device directly to the USB port on your computer.</span>

## <span style="color: rgb(52, 73, 94);">Cable length</span>

<span style="color: rgb(52, 73, 94);">USB devices can be connected to the computer without an amplifier with a cable of 5 m. For every subsequent 5 m, an amplifier must be used each. In theory, when using a standard resolution, the cables could be extended this way to 30 m. However we know that not all devices support this.</span>

## <span style="color: rgb(52, 73, 94);">When do I need a USB camera?</span>

<span style="color: rgb(52, 73, 94);">USB cameras are very easy to use. However, the settings may be limited, fo rexample, many USB cameras have fixed zoom. A USB camera may be perfectly suitable for a usability study in which you film a person sitting behind a computer. A USB camera also works very well to create video files for FaceReader. On the other hand, when you need to create a video file of a person further away from your camera, a USB camera may be less suitable.</span>

<span style="color: rgb(52, 73, 94);">For videos with accurate time information, needed for EthoVision XT, you need a high-quality USB camera.</span>

# GigE Vision cameras

<span class="FM_SC_23_2512">GigE Vision cameras are hereinafter referred to as GigE cameras.</span>

## When do I need a GigE camera?

GigE cameras are high-performance industrial cameras. They can have a higher frame rate and resolution than the other supported cameras. The images are sent unprocessed to the computer using a standard network cable (UTP). With a high frame rate and resolution this results in a very high transfer of data. You can connect a GigE camera directly to an Ethernet card on your computer. In this way you can obtain very high quality videos. An important advantage of GigE cameras is the possibility to have long cables between the camera and the computer.

## Network requirements

To use MediaRecorder with GigE cameras, the following network requirements apply:

- An Intel Pro/1000 CT or Intel Pro/1000 PT (1 Gb) network adapter needs to be installed in the computer.

[https://en.wikipedia.org/wiki/Category\_5\_cable](https://en.wikipedia.org/wiki/Category_5_cable)

- The cables must be suitable for Gigabit Ethernet. The minimum cable quality is CAT5e.
- We recommend to use a dedicated network.

## Install and setup

If you bought a complete solution from Noldus IT, the network adapter is present in the computer, the GigE cameras are set up and the MediaRecorder settings are made. If you bought your cameras and MediaRecorder separately, you must do the installation and setup yourself.

See [Set up GigE cameras](https://bookstack.noldus.com/link/475#bkmrk-page-title)

## Power over Ethernet

GigE cameras can be connected to a PoE injector. This is a device that passes power along with data (in this case, video data from the camera) on twisted-pair Ethernet cabling. Cameras may also be powered using a 2 or 4-port Network Interface Card (NIC).<span style="color: rgb(0, 0, 0);"> T</span>his way no separate power supply is needed.

## Supported GigE camera

- Basler GigE camera acA1300-60gm mono. Color space: Y800.
- Basler GigE camera acA1920-40gc color. Color space: RGB32.
