We’ve put together the most commonly asked questions about the HALO IOT Smart Sensor:

Integration & Alerting

How does it interface with a video management system?

HALO IOT Smart Sensor interfaces with a VMS in two possible ways. HALO can connect to a VMS via its event management system, thus allowing a direct correlation between the event time and the record time of a camera monitoring activities in/out of the room. HALO can also be connected to the VMS as a camera stream. The status of its sensors can be directly recorded as a video stream.

What VMS platforms integrate with HALO?

Since HALO is a security device, we want it to work with any VMS. HALO is currently integrated with multiple VMS platforms with more on the way! You can see all integration guides here.

How does a user get alerted to an event of aggressive/unruly behavior or vape detection?

Users can program what they want the HALO Smart Sensor to do.  Here are some of the options
1. Send an event message to the Security Systems
2. Send an e-mail or text message to designated personnel
3. Turn on its status light
4. Play a pre-recorded message to sound an alarm through its built-in speaker
5. Or, any combination of the above

Is there any protection from vandalism?

HALO is a SMART Sensor! As a security device, HALO is made of Vandal Proof plastic and has an IK10 rating. HALO Smart Sensor also encompasses a tamper sensor in order to detect someone trying to damage it. If the tamper sensor is set, an alert can be sent out in the same manner as a vape alert, or, as an option, HALO has a speaker and light which can be enabled to blink or shriek to alert of the tampering.

Installation & Set Up

Who can install the HALO vape detectors?

The HALO IoT Smart Sensor is very easy to install. It mounts in ceiling with a 5-inch circular opening and a single CAT5/6 cable with POE. We recommend you use an experienced security integrator to perform the installation to insure it is properly connected to your security system and is installed in the proper location. IPVideo has a network of Security Integrators throughout the USA and would be happy to recommend a certified installer.

Will HALO work right out of the box?

HALO does work right out of the box since firmware version 1.32. However, we recommend that you:

  1. Download and update to the newest firmware here. Please follow the “how to” document in the download.
  2. Set up notifications (SMTP Settings) Learn how to set up notifications here.
  3. Sync your HALO to a NTP server.

Minimal changes need to be made as the default events were made to fit majority of environments. You can turn on/off certain events and actions based on your preferences.

Once HALO is powered on, it requires 24 hours for the sensors to self-calibrate.

Do we need a camera license to install these devices?

HALO should not require a camera license in most cases if it is used only to send event messages to the VMS. If the end user wishes to record HALO’S MJPEG sensor screen, then a camera license would be required.

Does the system have required updates?

We are continuing to improve the performance and add new features to HALO. We recommend users keep HALO up to date with the latest firmware releases. The HALO device comes with a Utility Tool which allows updates to be pushed to one or more HALO devices. The end user will be notified when a new firmware version is available or can check on the IPVideo website. A cloud interface will be available in a future release which will allow the HALO to receive automatic download updates at specified intervals. This will require the HALO to have access to the internet.


What can HALO actually detect?

HALO has a host of sensors to perform multiple detections. 12 sensors to be exact. The hundreds of combinations it detects expands its capabilities to be able to differentiate between substances as well.  For instance, HALO can distinguish between a person vaping and a person vaping with a substance laced with THC. 

Some of the things HALO can detect are:

  • Particulate matter
  • Humidity that produces mold and other Fungi
  • VOCs
    • Trichloroethylene
    • Xylene
  • Ammonia
  • Carbon Monoxide
  • Carbon Dioxide
  • Vape
  • THC
  • Smoke
  • Light
  • Vibration
  • Pressure
  • Temperature
  • Sound Abnormalities

Will gunshot detection be included in my current unit?

Gunshot detection is included with all HALOs. IPVideo has a patent pending algorithm built into each HALO improving identification of gunshot events with Dual Authentication. HALO incorporates frequency and sound pattern with percussion to detect gunshot in 360 degrees at a 25’ radius for almost 2,000 square feet of coverage and does not require line of site.

What is the detection range?

HALO can typically cover 144 square feet with normal ceiling heights(8ft) for vape sensor however other sensors work effectively up to 1963 square feet. Its coverage area will also vary by the ventilation in the room, the ceiling height will also be a contributing factor. A pendant mount option is available to keep HALO at its recommended height of 8 feet.

What is the ppm threshold that it would need to trigger the devices?

 The PPM thresholds are programmable and thus can be varied by room to match the conditions in that room.

If vape is blown into a person’s jacket, will HALO detect this?

HALO was purposely designed to maximize efficiency of airflow which shortens the response time to an event. HALO is an effective tool to detect vape but will have obvious limitations if a person uses some physical methods to obscure their vaping. Filtering through clothing, opening of windows, etc. can lower the levels of chemicals reaching its sensors. Third party testing has been done and proven effective, even when blown in a jacket.

Does HALO record video or audio?


HALO does NOT record video. There is NO camera on HALO.

HALO does NOT record audio. HALO only captures decibel level readings; it does NOT record any conversations.

Can the readings from HALO be used as proof for legal action?

HALO provides indications of VAPE and/or THC based on the presence of chemical signatures and particulates in the air. Although a highly effective indicator it is not to be used as 100% proof for legal action. Security and Administrative teams should use these readings to conduct their searches for physical evidence and utilize this physical evidence and investigative procedures for the basis of actions. We have had numerous accounts that have been effective in these methods and we would be happy to provide these references. IPVideo Corporation can also recommend consulting services on investigative procedure and policy enforcement if you require.

Costs & Purchasing

How do I buy HALO?

IPVideo Corp. sells through a national dealer network that purchases through our authorized distributors. You can reach out to IPVideo who can direct you to a local dealer in your area or you can ask your preferred partner to procure them on your behalf.

Is there a minimum quantity to purchase?

No, there is no minimum purchase quantity.

Are there any re-occurring connection charges?

HALO can be viewed from any SMART device or computer. It does not utilize the cloud for any of its detection capabilities for privacy reasons. Since the unit is self-contained there are no re-occurring connection charges. We do recommend connecting HALO, since it is a security device, to your security system. You may of course choose to use an outside service to monitor its alarms and events.

What is the process for getting a demo unit?

Please contact your local sales rep or reach out to IPVideo Corp.

Does HALO have any warranties?

HALO comes with a 2-year warranty. Multi-year extended warranties are sold separately.


When to use HALO 2C or HALO 2.0?

IPVideo has released its first hardware addition to the HALO product line with the new HALO 2C hardware. As a dealer or customer, you are eligible to purchase both and it is important to know when to position each. While both products operate on the same software platform, HALO 2C adds calibrated CO2 (Carbon Dioxide), Temperature, and Humidity sensors that improve accuracy of measurements. This is particularly valuable when integrating HALO into your HVAC and building automation tools to remediate air quality conditions. HALO 2.0 is a powerful solution that will accurately identify many environmental conditions including Vaping, Vaping with THC, Gunshot Detection, Keyword Detection, Aggression, air quality trending, and much more that is also included with the new 2C version. While both the HALO 2.0 and HALO 2C hardware platforms include the Health Index, accuracy of the CO2 and Humidity measurements are enhanced utilizing the HALO 2C hardware. For more information please reach out to the IPVideo team at info@ipvideocorp.com.

Are these recommended for school bathrooms?

HALO IOT Smart Sensor is a security device which is designed to maintain privacy. Bathrooms and locker rooms are two such places HALO is installed. They are also perfect for dorm rooms, hospital rooms and hotel rooms to provide security while maintaining privacy.

Are these currently being used by any schools in the country, and if so, what successes have they reported?

HALO is currently in use in schools throughout the US and they have uncovered many instances of both vaping and THC use. We highlight some of these districts on our site. 

Would HALO work in college settings?

Yes, HALO is suitable for use in Colleges and Universities, hospitality centers, commercial buildings, malls, etc. Any location where vaping needs to be controlled and there is a security system or security service to monitor its alerts/events. HALO is perfect for dorm rooms if colleges are concerned about students smoking various substances in rooms, breaking noise ordinances or for dorm and campus safety.

How can the system be used in industrial complexes?

HALO is a SMART sensor with the ability to expand its capabilities in the future. HALO is suitable for use in any industrial complex where environments need to be monitored and controlled. HALO detects chemicals such as CO2, CO and NH3 and ties to the security system or security service to monitor its alerts/events.

Air Quality Terms

Particulate Matter

Particulate matter, or PM, is a mix of particles and droplets in the air. PM varies in shape and size, but those of 10 micrometers in diameter or smaller can adversely affect your health because they can be inhaled. PM 2.5 refers to fine particulate matter—that with a diameter of two-and-one-half microns or less.

Sufficient exposure to PM can irritate the eyes, nose, throat, and lungs, leading to allergy-like symptoms and shortness of breath in otherwise healthy people. It can also exacerbate existing medical problems, such as asthma and heart disease. PM  2.5 is considered the world’s single biggest environmental health risk.

Indoor PM levels can be influenced by outdoor sources like vehicle exhaust, wildfires, and power plant emissions. But many indoor activities produce PM as well: cooking, burning fireplaces, and smoking are just a few common sources.

VOC(Volatile Organic Compounds)

The acronym stands for volatile organic compounds, gases emitted from a variety of materials that can have short- and long-term health effects. Concentrations of many VOCs can be up to 10 times higher indoors than outdoors.

Sources of VOCs include many common products, including cleaning fluids, disinfectants, paints, and varnishes. Burning fuels like wood and natural gas also produce VOCs. 

Short-term exposure to low levels of VOCs can cause throat irritation, nausea, fatigue, and other minor complaints. Long-term exposure to high concentrations of VOCs has been linked to more severe respiratory irritation as well as liver and kidney damage. Products can emit VOCs even when they’re in storage, though to a lesser extent than when they’re actively being used.

Carbon Monoxide

By now, most people are aware of the deadly effects of high concentrations of this odorless, colorless gas. Exposure to lower levels sometimes given off by fuel-burning appliances can also cause adverse reactions, including confusion and memory loss.

Carbon Dioxide

While the effects of high levels of CO2 were long thought to be benign, research has found that concentrations as low as 1,000 ppm can affect people’s cognitive function and decision-making performance.

The greatest source of indoor CO2 is people themselves, as it’s a byproduct of our respiratory function. Coupled with poor ventilation, this commonly leads to high levels of CO2 in many workplaces.

Temperature and Humidity

These levels can affect more than your comfort. High temperatures and excessive humidity promote mold and mildew growth. These can cause structural damage to your workplace and cause allergy-like symptoms in those with sensitivities. Monitoring these levels can help you prevent facility and health problems and tip you off to potential sources like structural weaknesses and leaks.
