1. What Is an Explosion-Proof Security Camera?

An explosion-proof security camera is surveillance equipment designed to operate safely in hazardous environments. It achieves this through specialized structural design (such as flameproof enclosures and sealed encapsulation) and material selection. These features prevent electrical sparks and high temperatures generated by internal circuits and components from propagating outward. Simultaneously, the camera resists the ingress of flammable or explosive gases and dust from the external environment. Its core characteristic is obtaining authoritative explosion-proof certification, confirming compliance with safety standards for specific hazardous environments. Every stage—from design and manufacturing to testing—adheres to stringent explosion-proof specifications.

1) Core Advantages of Explosion-Proof Security Cameras

· Safety Without Hidden Hazards: The core advantage lies in “explosion-proof” design. Through flameproof and intrinsically safe construction, it eliminates explosion risks caused by electrical sparks or high temperatures, meeting fundamental safety requirements in high-risk environments.

· High Environmental Adaptability: Features resistance to high temperatures, low temperatures (-40°C to 60°C), dust, and water (IP68 protection rating), enabling operation in harsh conditions such as humidity, dust, and extreme temperature fluctuations.

· Precise and Comprehensive Imaging: Mainstream models incorporate dual-spectrum imaging technology (thermal imaging + visible light), enabling clear target identification in low-visibility conditions like darkness, fog, or haze. Select models support temperature measurement (-20°C to 550°C), enabling temperature anomaly alerts.

· Rich Intelligent Features: Integrated with intelligent detection capabilities like perimeter intrusion, tripwire intrusion, and fire detection. Supports alarm linkage (recording, snapshot capture, email notifications) to reduce manual monitoring costs.

· Stable and Reliable: Constructed with 304/316L stainless steel housing for corrosion and impact resistance. Select models support local SD card storage (up to 256GB), ensuring continuous recording during network outages and maintaining uninterrupted surveillance operations.

2) Why Must Hazardous Environments Employ Explosion-Proof Designs?

Hazardous environments (such as chemical plants, mines, and flammable storage facilities) contain combustible gases (e.g., methane, hydrogen), vapors, or combustible dust. The electrical circuits and mechanical friction of conventional cameras can generate sparks or high temperatures. If these come into contact with flammable substances, they can easily trigger explosions or fires.

The core value of explosion-proof design lies in “risk isolation”: it uses flameproof enclosures to isolate internal ignition sources from the hazardous external environment. Simultaneously, the enclosure possesses sufficient mechanical strength to withstand pressure and prevent rupture even if an internal explosion occurs, thereby preventing flame leakage. Furthermore, explosion-proof equipment must undergo rigorous temperature class certification (e.g., T6 class, maximum surface temperature ≤85°C) to ensure operating surface temperatures remain below the ignition temperature of combustible media, eliminating safety hazards at their source.

FAQs

1) What is the core difference between explosion-proof security cameras and ordinary cameras?

The core difference lies in “explosion-proof capability”: Standard cameras lack explosion-proof design, and electrical sparks or high temperatures generated by circuit operation may ignite combustible media in hazardous environments. Explosion-proof cameras, however, feature designs such as flameproof enclosures and sealed encapsulation to isolate internal ignition sources. Additionally, they undergo authoritative explosion-proof certification, enabling safe operation in hazardous environments. Furthermore, explosion-proof cameras exhibit significantly superior environmental adaptability (resistance to extreme temperatures, dustproofing, and waterproofing) compared to standard cameras.

2) How to choose explosion-proof cameras suitable for your specific scenarios?

· Consider the hazardous environment type: For gas explosion environments, select Exd IIC rating;

· Consider temperature requirements: For high-temperature environments, prioritize T6 rating (lower surface temperature);

· Consider monitoring range: For fixed small areas, choose TE365; for large-area dynamic monitoring, select TE464T1 PTZ cameras;

· Consider functional requirements: For temperature measurement and hotspot detection, choose dual-spectrum models; for long-distance monitoring, select TE464T1.

3) What precautions should be taken when installing explosion-proof cameras?

· Installers must possess explosion-proof equipment installation certification and strictly follow the product manual;

· Installation locations should avoid direct impact and corrosion sources, ensuring the housing remains undamaged;

· Wiring must use explosion-proof sealed connectors to prevent air leakage at cable interfaces;

· Regularly inspect the integrity of the equipment housing and seals to ensure explosion-proof performance remains effective.

4) What are the advantages of dual-spectrum imaging (thermal imaging + visible light)?

Thermal imaging operates independently of ambient light, enabling target detection in darkness, fog, haze, and smoke while simultaneously providing temperature measurement. Visible light imaging delivers clear, detailed imagery for precise target recognition (e.g., facial features, license plates). Dual-spectrum fusion technology balances “all-weather surveillance” with “detailed identification,” overcoming the limitations of single-spectrum imaging. This makes it particularly well-suited for complex monitoring requirements in high-risk environments.
