A laser pointer is a small, hand-held device that emits a beam of laser light. This device is made up of a few different parts, including a laser diode, a power source, and a focusing lens. 

The laser pointer is powered by a battery, and the light is emitted from the laser diode. Laser light works by emitting a single wavelength of light. This light is then amplified and focused into a single point. 

It is important to note that lasers can be extremely bright and powerful, which is why they can cause damage to camera systems and other sensitive materials.

Lasers can damage security cameras in a few different ways. When a laser light hits the camera lens, it can cause two types of damage. The first type of damage is called thermal damage. 

Thermal damage is caused by the heat that is generated when the laser light hits the lens. This can cause the camera lens to shatter or become distorted. 

The second type of damage is called optical damage. Optical damage is caused by the light that is emitted by the laser. This can cause the camera’s sensor to be damaged, which will result in a loss of image quality.

CCTV or security cameras are valuable pieces of equipment, and it is important to take whatever steps are necessary to protect them from harm. 

Laser pointer damage to the digital camera in a very short amount of time, so it is essential to take the necessary precautions. Follow these simple tips to help protect your CCTV camera from lasers:

1. Install Moving Cameras

A moving camera is a type of security camera that moves around to ensure that a wide area is covered. This is in contrast to a stationary camera, which remains in one spot.

Moving camera is becoming increasingly popular due to the fact that they can provide a more comprehensive view of an area, and they are less likely to be security camera pointed by vandals.

Installing a moving camera can help protect cameras from lasers. By having a constantly in motion camera, you can minimize the risk of sensor damage from laser pointers.

The movement of the camera will cause the beams to move around and avoid hitting the camera for extended periods of time. This will help to keep your camera safe from physical damage.

2. Set-up Infrared Filters

An infrared filter is designed to block infrared light from passing through them. This type of filter is often used in surveillance camera systems to help protect them from infrared lasers.

When laser beams hit an infrared filter, the filter will block the majority of the lights from passing through. This will help to prevent damage to the camera by preventing the laser beams from hitting the camera sensor for an extended time.

If you are using a security camera that does not have an infrared filter, you can purchase an infrared filter to attach to the camera. 

This will help to safeguard the camera from powerful lasers. Try to find a high transmission rating filter so that as much light as possible will be blocked.

3. Use an Alarm System

If you are worried about someone targeting your surveillance camera with laser pointers, you can use an alarm system to help safeguard them.

An alarm system will sound a loud alarm when it detects that someone is targeting your video surveillance system with a laser. This will help to deter potential vandals and safeguard your camera from damage.

4. Place Cameras in Protected Locations

One of the best ways to protect CCTV cameras from laser pointers is to place them in protected locations. 

Protected locations are areas that are less likely to be targeted by criminals. In order to protect your security cameras from laser pointers, it is a good idea to place them in higher areas, such as on a roof or in a corner.

You should also avoid placing your surveillance camera in areas that are easily accessible to the laser operator. This will help to keep your cameras safe from damage.

5. Use Laser-Proof Glass

Laser-proof glass is a type of glass that has been treated to be resistant to the damage caused by lasers. 

It can be used to safeguard cameras, eyeglasses, and other sensitive equipment from the damage caused by lasers. 

Laser-proof glass is available in a variety of different thicknesses, so you can find one that will fit your needs. Installing laser-proof glass is easy, and it can help to protect your camera sensor from lasers.

6. Setup Blinding Notification Software

If someone is targeting your security camera sensor with a laser, you can use software to help protect them. 

Blinding notification software will notify you when someone is targeting your security cameras with a laser. This will allow you to take action to safeguard your cameras from damage.

7. Install Multiple Cameras

When possible, it is a good idea to install multiple security cameras. This will help to provide additional protection for your cameras. 

If a laser pointer targets one camera sensor, the other cameras will still be able to capture footage. So, the criminal will not be successful in completely disabling your security system.

Why Do People Attempt to Blind the Camera?
