    I mean surveillance!
    Cameras in front of the store!
    Can some bullies break them by shining a laser?

    The laser beam can damage the camera's sensor, but either it would have to have high power, or the process of direct illumination of the sensor would have to be long-lasting (and not momentary, implemented with a "shaking paw").

    How to protect yourself?
    In my opinion, this is the wrong question. I would suggest the following: how to minimize the risk of damage?
    Good lenses (or cameras with built-in good lenses) should be used to minimize the risk of damage. Good, i.e. having the ability to automatically control the aperture, preferably with a built-in T360 ND filter.
    The vast majority of the most popular (ie the cheapest) integrated cameras from leading manufacturers have lenses with a fixed aperture. A diaphragm is a hole through which light falls on the camera's sensor (converting optical impulses into electrical ones).

    Why the exclamation marks in every sentence of the last post? This is not a Forum where a person creating a topic or asking a question should automatically impose a demanding attitude on himself. The more so that the answers given by a colleague with the nickname robocop were precise and adequate to the questions posed in the first post.

    And finally - I would like to remind you of the spelling rules in Polish. Do not put a space before: period, ellipsis, colon, exclamation point, comma, question mark, closing parenthesis, closing quotation mark.

    I'm afraid that this is enough to destroy the cmos matrix.

    I confirm that an ordinary laser can damage the camera matrix (not burn out completely, but damage the elements of the matrix field) - unfortunately, it is impossible to eliminate the possibility of damage to the matrix in 100%, but on the other hand, when the camera hangs at 2-2.5 m, it is difficult to hit the laser (this is not about driving over the lens, but about maintaining the exposure level temporarily).

    Thanks for the answers.
    My main concern is whether the lasers available on Allegro for, for example, PLN 100 can damage the surveillance camera.
    I expect juvenile rascals who will tease for "fun" rather than sabotage.
    Because those cheap laser pointers (I hope) are unlikely to do anything!

    Theoretically, setting the laser at the right angle will easily damage the camera and it will be rather difficult to do something about it.

    Not theoretically, but practically and not at the right angle, but right in front of the lens. And it will break easily :) . Due to the fact that this is a specific type of light, with a narrow spectrum and a low divergence beam, it is rather impossible to protect the transducer.

    I wrote theoretically because some time ago I shone in the converter in my phone and it didn't break down (I didn't know the danger xd). It was a laser with two batteries, it shone quite strongly (better than the cheap ones, e.g. in some pens for a few zlotys), so maybe it still didn't have enough power.

    It's good that you didn't try to shine a light in your eye.

    Well, everything is clear
    So ..... neighborhood rascals are a threat to the store monitoring.
    And this message will be sent to the investor.
    It's not the best news, but it's hard to be aware of what and how

    Thank you all for your replies
    Regards

    Conclusions drawn with a large margin of error. If such conclusions were drawn to other basic questions about our existence (Is it safe to drive a car? Is it safe to travel by plane? Is it safe to run a store? Is it safe to cross pedestrians on green light lanes), then it would probably be suggested to the questioner, to build himself a shelter and spend his life there (but will staying in a shelter all his life guarantee safety?). The "neighbourhood rascal" will sooner be a threat to the condition of the shop facade or glass windows than to the shop's monitoring system.

    I would suggest reading it again (with understanding) my previous post . And then ask yourself these questions:
    - How many monitoring systems have been rendered harmless by means of a laser device available for the standard "neighborhood rascal"? Installers, service technicians and distributors of cameras speak on this Forum. Do they report a common problem with the activity of "laser throwers"? I do not think it is a high-powered device (as in the Youtube link), because how many such devices are owned by citizens of our country. At most, it will be laser pointers.
    - Is it possible to minimize the risk of damage to the sensor in the camera? I gave the hint in the post.

    If you have a recorder, you can see who is throwing a laser at the lens.
    Further downhill.

Topic summary

✨ The discussion centers on the potential damage that laser beams can inflict on camera sensors, particularly in surveillance systems. Users express concerns about the risk posed by inexpensive laser pointers, suggesting that while high-powered lasers can indeed damage a camera's matrix, the likelihood of damage from low-cost lasers is lower. Recommendations for protection include using cameras with good lenses that have automatic aperture control and built-in ND filters. The conversation also highlights the difficulty of protecting cameras from laser damage due to the specific characteristics of laser light, which can easily focus on the sensor. Overall, while the risk exists, the consensus is that the threat from common laser pointers is relatively minimal.

FAQ

TL;DR: At 2–2.5 m mounting height, aiming a pointer is harder; "an ordinary laser can damage the camera matrix." Use auto‑iris lenses and ND filters to reduce risk, but no setup is 100% laser‑proof. This FAQ helps CCTV buyers and installers minimize laser damage risks. [Elektroda, mikan4, post #17534757]

Why it matters: Laser misuse can permanently scar sensors, disrupt evidence, and force costly camera replacements.

Quick Facts

Can a laser damage a CCTV camera sensor?

Yes. Forum users confirm that ordinary pointers can damage a camera sensor. Damage often stays local, leaving scarred pixels or streaks. Maintaining exposure on the sensor matters more than a quick sweep. A 2–2.5 m mount makes steady aiming harder. [Elektroda, mikan4, post #17534757]

What’s the simplest rule to avoid laser damage?

Follow the rule: "Do not shine the laser into the lens." That means no direct beam should ever reach camera optics. [Elektroda, robokop, post #17528977]

Can consumer laser pointers break store cameras?

Yes, if someone holds the beam directly in front of the lens. The beam is narrow‑spectrum and low divergence. In that case, "it will break easily." [Elektroda, robokop, post #17539100]

Does a quick, shaky hit cause damage?

One contributor noted damage needs high power or sustained illumination of the sensor. He contrasted it with a momentary hit done with a "shaking paw". [Elektroda, treborsz, post #17533849]

How should I mount cameras to reduce risk?

Mount cameras around 2–2.5 m high to make aiming harder. This height complicates holding the beam steady on the sensor. That reduces the practical chance of damage by casual vandals. [Elektroda, mikan4, post #17534757]

How do I choose a safer camera against lasers? (3 steps)

Pick optics that minimize incoming energy.
  1. Choose lenses with automatic aperture control (auto‑iris).
  2. Prefer cameras with a built‑in ND filter, e.g., T360.
  3. Avoid fixed‑aperture lenses in integrated budget models. [Elektroda, treborsz, post #17533849]

Do auto‑iris and ND filters fully protect the sensor?

No. Laser light is narrow‑spectrum and low divergence, which makes shielding difficult. Even with filters, a direct beam can still damage the transducer. [Elektroda, robokop, post #17539100]

How powerful are typical consumer laser pointers?

Typical consumer laser pointers are limited to ≤5 mW output (Class 3R). The FDA advises avoiding direct exposure to laser radiation. [FDA, 2022]

Do YouTube demos of laser damage reflect real risk?

Yes. Aligning a laser directly in front of the lens can damage sensors. It is not about a special angle, just direct aim. [Elektroda, robokop, post #17539100]

Are CMOS CCTV sensors especially vulnerable?

Yes. A direct laser exposure can be enough to destroy a CMOS matrix. Avoid letting any beam reach the sensor. [Elektroda, robokop, post #17534063]

Are laser attacks on shop cameras common or overblown?

Experienced contributors say such incidents are uncommon versus other vandalism. Focus on minimizing risk with better optics, not worst‑case assumptions. [Elektroda, treborsz, post #17541679]

I briefly hit my phone camera with a laser and nothing happened—why?

One user reported no damage after a brief hit with a two‑battery pointer. He suspected the pointer lacked enough power to cause damage. [Elektroda, makosuu, post #17540397]
