Perpetrators are using lasers (particularly high-powered infrared lasers) to overwhelm sensors, cause image distortion, or permanently damage camera components. Paintball guns obscure lenses with paint. Wi-Fi jammers and electromagnetic interference (EMI) devices disrupt signal transmission through electrical noise. Recently, on Fox News in February 2026, a former FBI Special Agent commented that a well-thought-out plan to turn off a camera across the street is possible with a well-placed laser to burn out its lens.

• Infrared (IR) lasers: Particularly effective against security cameras, especially those with IR night-vision capabilities, since the sensors are designed to detect infrared wavelengths.

• Green lasers: More visible and commonly used; can damage cameras at sufficient power levels.

• Industrial/research-grade lasers: Can cause immediate, irreversible damage.

Wi‑Fi jammers block wireless signals, stopping devices from streaming, recording, or communicating. The disruption lasts while the jammer is active and until devices reconnect. Since modern security systems use Wi‑Fi to send alerts, stream camera footage, and connect to apps, jammers can disable these functions—causing missed alerts, lost video, or total system failure, leaving a property unprotected. Perpetrators can buy Wi-Fi jammers online or in stores for as little as $100.

Wi‑Fi uses set frequency bands, mainly 2.4 GHz and 5 GHz. A Wi‑Fi jammer sends signals on those bands, interfering with devices trying to connect. By flooding the channels with noise, the jammer blocks normal Wi‑Fi signals. As a result, devices can’t send or receive data properly and may be disconnected or unable to join the network.

Lasers (laser pointers) can pose a significant threat to security cameras that can manipulate both hardwired and wireless security cameras. High-powered infrared lasers can overwhelm camera sensors, causing image distortion and unusable footage, temporarily blinding the camera’s monitoring capability. Perpetrators can also buy a laser pointer online or in stores for as little as $20.

When a laser beam is directed into a camera’s lens, it creates an intense glare that washes out the image by exceeding the camera’s light management range. Even cameras with a wide dynamic range struggle with such intense light sources, producing unusable footage that appears engulfed in an impenetrable haze and rendering the camera ineffective for surveillance.

Yes, high-powered lasers, particularly those used in industrial settings, can inflict irreversible damage on a camera’s internal components. Such lasers can burn out individual pixels in the sensor or create hairline fractures in the delicate lens. Prolonged exposure to a concentrated laser beam can cause device malfunction and may require costly repairs or a complete camera replacement.

• A: Low-powered (under 5mW): Can cause temporary blindness but typically won’t cause permanent damage unless aimed steadily for extended periods.

• Mid-powered (5mW - 500mW): Can damage sensors with prolonged exposure.

• High-powered (500mW+): Can cause permanent sensor damage and lens burns; Class 3B (5-500mW) and Class 4 (500mW+) lasers are most dangerous.

NO, devices such as cellphones, computers, electric motors, towers, and various types of transmitters generate Electromagnetic Interference (EMI). These can disrupt power supplies or communication signals if the hardwired system includes electronic communication, even if it mainly depends on direct wiring. Moreover, some sophisticated perpetrators may employ specialized tools designed to disrupt power lines or low-voltage communication lines utilized by security systems.

Electromagnetic interference (EMI) can impact security system performance and reliability. Security systems rely on consistent signal transmission between devices. EMI from nearby electrical equipment, radio waves, or poor cabling introduces noise that distorts these signals, leading to degraded video quality, communication failures, or complete feed loss in surveillance systems.
