Pointing a laser at a security camera may look like a clever escape trick in fiction, but in the real world it is a costly and illegal gamble. The concentrated beam can overwhelm a camera's sensor, producing a temporary whiteout or, with sustained exposure, permanent dead pixels and dark spots. In a 2021 Florida case, a man was arrested after leaving dead spots on church surveillance cameras, causing more than $2,000 in damage—and the cameras still caught him on video.
Not every laser is a threat, however. Under FDA rules, handheld laser pointers sold legally in the US are capped at 5mW of output power, which is unlikely to do more than create a brief glare. Causing real damage requires a much stronger laser held perfectly still for about 10 seconds. That is harder than it sounds: researchers at IPVM found it "very difficult" to keep a beam on target from just 5 feet away, and modern cameras include sensor protections that make permanent injury even less likely.
For businesses, the practical takeaway is that laser vandalism is more of a nuisance than a fatal flaw—but it can still lead to repair bills and downtime. The article recommends making cameras harder to target by placing them high or at sharp angles, using moving cameras, and overlapping coverage so no single camera is a critical blind spot. Adding systems that detect sudden light changes and send instant alerts can also help security teams respond before a laser does lasting harm.
