With the power of social media, iProjector disrupts and generates visual moments that are easily captured and shared by mobile, amplifying audience reach.


You need Internet access and a Halo-supported playback device.

Halo is an online service, so you need an Internet connection for signing in and managing your monitors. A Halo-supported playback device is required for each monitor (either a Raspberry Pi you build yourself, or our very own Halo Player). Internet connectivity is also required for the Halo Player devices installed, either wireless (WiFi), wired (LAN) or mobile (using a 3G/4G/LTE USB dongle).

NO. Halo was designed from scratch so that anyone can use it.

Forget the tech-stuff. Our service is really easy to use and you can get our Halo Players that are really plug-and-play. Honestly.

Halo uses scalable technologies that can support tens of thousands of monitors under a single Halo account. We provide mass management of multiple monitors, along with tag-based searches, making Halo an easy solution for handling thousands of units.

Halo software supports any type of monitor, of any resolution.

The service was designed based on the primary resolution of 1920×1080 (dubbed “Full HD” or “1080p” in the TV industry). Halo player box also supports 4K resolution. The content is automatically adapted for any resolution and any monitor, even non-widescreen monitors.

It comes with each license purchased, one player per license.

Any Halo Player you order will be preconfigured with your account details so that you can simply plug it in and start “Haloing”

If you need any advanced configuration, you can provide it through the ordering process. For example, you can supply your WiFi network name and key and the Halo Player will come ready to connect to your WiFi network.

There is a limited worldwide warranty of 1 year on the Halo Player.

But first, you should follow the Halo Player troubleshooting guide. It might save you precious time and money.

If your Halo Player is eligible for replacement, you can ship the failed Halo Player back to us and we will send back the replacement unit within 2-3 days of receipt. Shipping costs for returning of Halo Players are covered by you, whereas we will cover for the shipping costs of the replacement unit if it’ a warranty related issue..

In order for you not to incur unnecessary shipping costs, make sure you go through the troubleshooting guide. You might get yourself a local part replacement which might be cheaper than shipping it back to us.

Halo can display a composition of videos, images, documents, online web pages and widgets.

You can upload whatever media files you want to Halo and use them. We also support YouTube videos, Live Streaming Videos (YouTube, Ustream, and custom streams) and PowerPoint files (converted to videos, keeping all animations). All Document types are supported and shown as slides, including PDF, PowerPoint, Word and Excel files. Our Widget collection, including Scrolling Text (ticker), Rich Text, RSS Feed, is now available to use and we are working on adding more.

It’s really no comparison.

Most TVs with a USB port allow you to load some media files on a USB drive and select to play them back sequentially. That’s it.

Halo automates the process of playback. It can turn the TV on and off, change the channel to the proper HDMI input and make sure everything goes smooth without glitches even after a power failure. And, of course, you can continuously update the content over the Internet without using USB sticks. Also, Halo provides a scheduling feature. You can setup your monitors to show different things on different hours, or even power off your monitor to save power.

And all of that without discussing about Halo being able to composite screens with multiple content, using YouTube videos, PPTs, live streaming videos, etc.

We include the Official Raspberry Pi power supply, with plugs suitable for worldwide use.

We include a 3ft (1m) micro-HDMI to HDMI cable (male-to-male), tested for 4K 60 Hz resolution.

Within Halo, there are 4 simple concepts: Media, Playlists, Widgets and Screen Layouts.

Media, which are things that you create or upload to Halo and get displayed, like image files, video files, documents or web site addresses

Playlists, which are a collection of media that gets displayed one after the other, with a duration that you specify (to create an image slideshow or video playlist)

Widgets, which are drop-in, small apps displaying useful info, like RSS feed, Ticker, Rich Text, Analog/Digital Clock etc.

Screen Layouts, which are a composition of playlists, media and widgets, placed on a virtual monitor, e.g. a full-screen image slideshow with a video playing on one corner.

After you create your screen layouts, you just assign a default show to each of your monitors.

Beyond the default show assigned to each device, you can also assign it a single Schedule.

The Schedule determines the exact time different screen layouts get displayed. So, for example, you can setup a different show for different hours or days, or schedule to display a specific show at a given time-frame. It is very easy, but very powerful.

By using a Schedule, you can also setup the hours that you want to power-off your monitors in order to cut on electricity bill.

In an event of Internet outage, Halo-enabled screens will continue to work fine, up to a full month.

Content displayed on your monitors is downloaded and played locally. But you won’t be able to change what gets displayed until Internet access is back. Of course, content that loads from the Internet, like Web Pages and Live Streaming Videos (except simple YouTube videos, which are downloaded locally), is not available when your devices go offline.

Yes. Halo fully supports monitors mounted vertically.

You can design many layouts for your screens, for different resolutions, orientations and ratios. So, you can have a Show with 2 layouts, one 16:9 horizontal and one 16:9 vertical. When you assign this Show for playback, each Player selects the appropriate layout depending on its ratio and its configured orientation.

You can set HTTP Proxy and Username/Password through the configuration file. You can edit this configuration file through your PC and an SD card reader.

For our Halo Players, all Network Settings can be configured during ordering, so it works great as soon as you plug it in!

You can set the WiFi network name and key through the configuration file and Halo will try to connect. All of the settings are configurable through the online Halo Portal. You also can edit this configuration file through your PC and an SD card reader.

For our Halo Players, all settings can be configured during ordering, so it works great as soon as you plug it in!

Yes, by using a USB dongle.

You just need to connect a 3G/4G/LTE USB dongle to the Player. All settings, like APN, Username, Password, PIN, etc, are configurable through the online Halo Portal. You also can edit this configuration through your PC and an SD card reader directly on the SD card.

For our Halo Players, all settings can be configured during ordering, so it works great as soon as you plug it in!

You can set the static network information through the configuration file. All of the settings are configurable through the online Halo Portal. You can edit this configuration file through your PC and an SD card reader.

For our Halo Players, all Network Settings can be configured during ordering, so it works great as soon as you plug it in!

Very. We designed Halo from the ground up with security in mind.

The Halo service uses bank-grade security encryption, while Halo software is always firewalled, even within your network. Nobody will ever be able to mess with your monitors. You can also fully customize the security features provided.

Very. Nothing can ever affect your screens.

Even in the remote case that our servers go down, your monitors will continue to work up to 1 month with the schedule you have already provided.

Note though that Halo is not a file storage service. You should always keep copies of the content you create outside of Halo. Always.

Any types of images that can be displayed in a modern browser.

These include JPEG, PNG and GIF (incl. animations). Images are resized upon display, so no pre-processing is performed. It is better not to use images of extremely high resolution, because this will slow down your Player. If you have images with resolution significantly higher than 1920×1080, try resizing them before you upload them to Halo.

Halo supports a wide variety of video formats.

Videos that you upload on Halo are automatically converted to industry-standard formats (H.264 with AAC audio).

YouTube videos are supported out-of-the-box, so they just get downloaded in the best possible quality (up to 720p right now). Halo also supports Live Streaming Videos (YouTube, UStream, or custom HLS or RTMP/RTSP streams). These will have to be delivered by the stream in H.264 format to make sure they will be played back on Halo Players. We also support multicast LAN video streams.

Halo also allows you to upload a PowerPoint file and get it converted to video on our servers, retaining all transitions and animations.

Finally, Halo offers the option to select if you want to use “crop” (completely fill the region by cropping edges) or “fit” (black borders are added to compensate for the aspect ratio).

We support PDF, PowerPoint (PPT/PPTX), Word (DOC/DOCX), Excel(XLS/XLSX) files.

These Documents are displayed as slideshows, one page at a time, and you can set individual timings for each page through the Halo Portal.

Remember: Halo already allows you to upload a PowerPoint file in the “Videos” section and get it converted to video on our servers, retaining all transitions and animations.

You can display any number of image slideshows, webpages and widgets at the same time, within reason of course.

If the widgets require a lot of processing and the hardware is not up to it, you might notice some sluggish animations depending on the type and content of the webpages and widgets.

Note that you can display only one video playlist at any given time. This is a restriction imposed by the hardware of Raspberry Pi, which cannot playback more than one video simultaneously. In most cases, you should not need it. We are planning to provide an advanced option for removing this restriction soon.

Halo requires a substantial amount of bandwidth.

Make sure you use the Halo service over a non-metered/unlimited Internet access. Same applies for the Halo players. Huge video files may be transferred through the Internet and constant communication of the players with the service may skyrocket your bill.

If you are on a metered/limited Internet connection (e.g. mobile carrier, or per-traffic / per-hour access), please contact us to ensure that you can use our service over those Internet connections.

Internet access is not smooth everywhere. We want you to have the best experience possible.

We could stream content, but that would mean that your Internet connection should be stable. Same goes for your WiFi network. If anything between your monitor and our server is a bit slow, it would not work properly. That is why everything is downloaded locally on the SD card (or hard drive, in case of a PC) and played from there.

Currently, no. You can upgrade your SD card though.

As soon as you set a schedule, that schedule should use at most 4GB of media. You can upgrade the SD card to a 32GB one and allow for 24 hours of high-resolution video.

Do not worry though. We will soon be supporting USB storage extension, allowing you to add additional media storage capacity using USB memory sticks or USB hard drives.

Halo software supports any resolution, thus any monitor size.

From 640×480 VGA monitors, up to the latest 4K TVs, all monitors will work fine. It is best to choose a widescreen monitor with an aspect ratio of 16:9 (like “HD Ready”, “Full HD” or “4K” monitors and TV).

Halo Player (or Raspberry Pi in general) should also work fine with 99% of all monitors and TVs out there, so do not worry much.


We do have detailed instruction on creating a video-wall using Halo using 1 Halo Player for each screen, plus one “master” Player. You can create really inexpensive video-wall setups that can be matrix-like (2×2, 3×3) or can even be asymmetric, with any layout you can imagine.

Alternatively, you can use an HDMI video wall controller and use a single Halo player to drive a large video wall as a single screens.

We use the HDMI standard called CEC. Almost all TVs support it.

Halo Player (or Raspberry Pi in general) includes a CEC adapter on its HDMI monitor port. CEC is a standard communication protocol supported by most major TV manufacturers. It allows for a playback device (Halo Player) to power on, power off, and switch video inputs on a CEC-enabled TV. Check out the CEC compatibility chart.

If your monitor does not support CEC (e.g. you have a computer monitor), Halo Player turns off the HDMI port to allow for the monitor to power-down by itself. This function is supported by all current monitors, even TVs.

In the future, we will provide support for using infrared LEDs to signal the monitor on or off through IR. For large installations, we can support custom solutions, like the above, or use custom serial connections to monitors.

No, there is no limit whatsoever. You can upload as many videos and images as you want.

Halo provides 24/7 online support for all users.

Just login to your account and drop us a word. We’ll help you out ASAP. But we usually provide a first response within 24 hours to all requests.

For Annual subscriptions, we also accept monthly direct debt.

It is a monitor that you can use.

Each monitor under your Halo account can either be “registered” or “unregistered”.

Registered monitors are monitors that have been paired with a Halo account.

Unregistered monitors in your account do not have a real-world counterpart, and are waiting for a player to register.

Both registered and unregistered monitors can be managed the same way under your Halo account, so you can configure settings, assign schedules, etc. But unregistered monitors cannot be actually used to display stuff, until they get registered by Halo Player.

Can I have an annual plan on Halo?

Yes. Just select the Annual Plan and add your Halo players.

No, there is no limit whatsoever.

You can upload as much content as you want and do as many changes as you want. The only limit imposed is the number of registered monitors. As long as you subscribe for the number of registered monitors you want to operate, everything else is unlimited!

Yes. Online support service is included in your standard Plan. You may require a screen dial in support which is available on Pro license subscription.

If you have a large project that requires on-site presence or deployment services, contact us.

You can add as many monitors as you want and can use them as soon as they get connected.

New monitors will appear as unregistered in your account until the player gets connected for the first time and registers successfully. You can manage unregistered monitors just like registered ones, they just have not been paired with an actual player.

Your subscription includes a limit on registered monitors. If you have reached your limit of registered monitors, then you will not be able to register any new ones. In case you want to increase this limit, just update your subscription with the new number of monitors you want to operate.

You have to delete the registered monitors that you no longer require.

Players of deleted monitors will be de-registered and the monitors will constantly display a relevant message, waiting for registration.

Charges are fully automated, so you will be billed (or credited) the difference of your plan, so do not worry about losing service credit.

Automated emails will be sent to you. If no action is taken, your players will eventually stop playback.

We want to make sure that charge failures do not mess up with your deployment. Monitors are usually in public view, so we want to be careful and discrete.

If a charge fails, an automated email will be sent to your designated email address notifying you of the problem and urging you to take action. We will keep sending these emails every day.

If the charge cannot be completed within 5 days, we will automatically display a flashing red image (without any text) for 2 minutes every 2 hours to alert you of the issue.

If the charge cannot be completed within 2 weeks, we will automatically downgrade your account to standard from PRO. All registered monitors will be de-registered, only 1 monitor will be left as registered (the earliest one).

At any point, you can prevent this by logging in and updating your billing details.

To cancel your subscription, you can go to the subscription panel and set to number of monitors to 1, deleting all other monitors from your Halo account. If you want us to completely remove your account and media, drop us and email and we will do so.
