Tech Tips: Can a laser pointer damage a CCTV camera? Discover the full truth behind this hack often seen in movies..
Opening a door with a hairpin is a common trope in books, films, and video games. However, if you have watched the popular series 'Better Call Saul,' you might recall a more sophisticated 'tech hack' in one of the episodes from Season 4. In this episode, a character named Werner Ziegler uses a laser pointer to disable a security camera, allowing him to make his escape. While this trick appears clever, is it actually effective in real life? The answer is yes—but it is not quite that simple.
A laser pointer can temporarily blind a security camera, and in some cases, even cause permanent damage. Achieving this, however, requires a very powerful laser, a specific type of (often older) camera, and the steady hand needed to keep the laser focused on a single point without wavering. But how exactly can a laser damage a security camera? Let’s find out.
What effect does a laser have on a security camera?
Like standard cameras, CCTV cameras rely on light to capture images. If an intense light hits the lens, the resulting footage is compromised. Lasers, by nature, emit high-intensity light beams. Most CCTV cameras utilize CMOS or CCD sensors; when a laser is directed steadily onto these sensors, the light intensity exceeds the camera's operational threshold, causing the video feed to go blank.
High-power lasers also generate significant heat. If focused on a camera for an extended period, this can result in 'dead pixels' or dark spots appearing in the footage. If the laser is powerful enough, it can render the camera completely inoperable.
Outsmarting modern cameras is no child's play.
Not every laser light is capable of damaging a camera. This can only be achieved by keeping a high-power laser perfectly steady for 10 seconds. If the laser's power is less than 5mW, it will merely create a brief flash on the camera, causing no permanent damage.
Furthermore, modern-day cameras incorporate new technologies and sensor protection features. Vince Gilligan, the co-creator of 'Better Call Saul' himself, acknowledged that the laser hack depicted in the show would only work on older cameras from the 1960s.
