![]() ![]() A laser creates a super bright and focused spot on the CCD (camera sensor).Second the quality of the camera you are trying to disable. First, the strength in mW of the laser you are using. I've experimented with this attack previously. ![]() Just a quick edit for those who (like me) was not sure whether this question was appropriate for the site, I have posted a question on Meta. IP)?ģ - Is the laser pen attack the only vector against those devices (apart from obvious things like fire, TNT, acid, shooting, etc)?Ĥ - Why are cameras still vulnerable to it, if at all?ĥ - Finally, how can I prevent those type of attacks against my cameras (they are all IP-based)? I figured out that this was because those posts light automatically when it gets dark (meaning lack of light) and as soon as it gets bright (meaning light went inside its sensors) the light would turn off.ġ - How does this laser attack apply to cameras?Ģ - For which types of cameras does the laser pen attack work against (CCTV Vs. I remember some 10 years ago kids in my neighborhood had found out that you could 'DoS' the street lights using the same technique (by pointing the laser to a point near the back of the light bulb). I was highly impressed by 's answer, and particularly about disabling cameras: " all you need is a decent pocket/torch size green laser (532 nm) directed for a few seconds directly into their CCD/CMOS sensor.". Basically he had asked whether " an attacker can identify if a CCTV camera is on/operational without direct physical access to the cable/camera". Has asked a great question and I would like to follow up on that. ![]()
