In hazardous environments where the risk of explosions is a constant concern, choosing the right surveillance equipment is critical. Explosion-proof cameras play a vital role in ensuring safety and security in such settings. However, selecting the appropriate camera for your facility requires careful consideration of various factors. In this guide, we’ll explore the key aspects to keep in mind when choosing explosion-proof cameras to safeguard your facility and personnel.
Understand Hazardous Areas Classifications
Before selecting an explosion-proof camera, it’s essential to understand the classification system for hazardous areas. These classifications dictate the specific certifications required for cameras to ensure compliance with safety standards such as ATEX or UL classifications. ATEX standards are recognized in European countries, UL standards in North America, and IECEx are international standards.
UL uses the Class/Division/Group system to categorize hazardous areas. The Classes refer to the general nature of hazardous materials present in the surrounding atmosphere, while the Divisions indicate the likelihood of these materials being present in an explosive or ignitable quantity. The Groups specify the type of hazardous materials present. Once you determine the appropriate standard and classification for your facility, you can start your search for an explosion-proof camera that satisfies your requirements.
Classification System for Hazardous Areas: Classes, Divisions, and Groups
| Class | Division | Group |
|---|---|---|
| I – Flammable vapor or gas may be present | 1 – Ignitable concentrations of hazards exist under normal operation conditions and/or where hazard is caused by frequent maintenance, repair work, or equipment failure. 2 – Ignitable concentrations of hazards are handled, processed, or used, but are normally confined within closed containers or closed systems from which they can only escape in cases of accidental rupture of these containers/systems or in cases of abnormal equipment operation. | A – acetylene B – hydrogen, butadiene, ethylene oxide, propylene oxide, acrolein C – ethylene, cyclopropane, ethyl ether D – acetone, ammonia, benzene, butane, ethanol, gasoline, hexane, methane, methanol, naphtha, natural gas, propane, toluene |
| II – Combustible dust may be present | 1 – Ignitable concentrations of hazards exist under normal operation conditions and/or where hazard is caused by frequent maintenance, repair work, or equipment failure. 2 – Ignitable concentrations of hazards are handled, processed, or used, but are normally confined within closed containers or closed systems from which they can only escape in cases of accidental rupture of these containers/systems or in cases of abnormal equipment operation. | E – combustible metal dusts such as aluminum, commercial alloys, magnesium F – combustible carbonaceous dusts such as carbon black, charcoal, coal, coke dusts G – other combustible dusts such as chemicals, flour, grain, plastic, wood |
| III – Ignitable fibers or flyings may be present | 1 – Ignitable concentrations of hazards exist under normal operation conditions and/or where hazard is caused by frequent maintenance, repair work, or equipment failure. 2 – Ignitable concentrations of hazards are handled, processed, or used, but are normally confined within closed containers or closed systems from which they can only escape in cases of accidental rupture of these containers/systems or in cases of abnormal equipment operation. |
Assess Environmental Conditions
The environmental conditions of where the camera will be installed is another thing you should consider. Carefully evaluating factors such as temperature and moisture levels is essential for ensuring optimal camera performance. For instance, in extremely cold environments, opting for a camera with a built-in heater can prevent operational issues. Conversely, for monitoring high-temperature areas like furnaces, a camera with a built-in blower or cooler can effectively regulate the camera’s internal temperature. Additionally, in environments prone to moisture or humidity, choosing a camera with wipers ensures clear visibility by preventing condensation buildup on the lens.
Evaluate Power Source
The installation environment also impacts the power source requirements for the camera. Opting for an explosion-proof camera that supports PoE (Power over Ethernet) provides flexibility and seamless integration with existing security systems. For outdoor or remote locations, consider integrating the camera with a solar-powered CCTV trailer. Using a solar CCTV trailer eliminates the need for an electrical power source since the camera uses solar energy for power.
If this sounds like something you need, 2M Technology can make it happen. We can seamlessly integrate any explosion-proof camera onto our solar-powered CCTV trailers, allowing you to effectively monitor outdoor or remote hazardous areas.
Determine Camera Features
Explosion-proof cameras vary in features and capabilities, so it’s important to determine your specific needs before making a choice. Consider factors such as resolution, field of view, optical zoom, low-light performance, and video analytics capabilities, and assess whether the camera meets the monitoring needs of your facility. You should also ensure that the explosion-proof camera you choose is compatible with your facility’s existing surveillance infrastructure. Check compatibility with recording devices, video management systems, and network protocols to facilitate seamless integration.
Future Scalability and Upgradability
In addition to addressing your current needs, it’s important to also think about your future needs when selecting an explosion-proof camera. If you anticipate future growth, opt for a camera that offers scalability and upgradability options to accommodate evolving security requirements and technological advancements. Consider factors such as the camera’s compatibility with future software updates, expansion modules, and additional features that may become necessary as your facility expands. Investing in adaptable cameras ensures long-term viability and minimizes the need for frequent replacements or upgrades as your security needs evolve.
Consider Using a Custom Explosion-Proof Housing Instead
Let’s say that you’ve identified all the features you need in an explosion-proof camera but can’t seem to find one that ticks off every box on your list. What do you do now? Settle for the closest option available? You could do that, or you could get a custom explosion-proof housing from 2M Technology instead. With a custom housing, you have the freedom to use any security camera with all the features you want in hazardous areas rated Class I, Division 1 or Class I, Division 2.
So, if you’ve found a non-explosion-proof camera that matches your needs, we can create a tailor-made explosion-proof housing for it. We can design housings for various camera brands like Verkada, Cisco Meraki, Ubiquiti, and more.
