I Need Solutions For Blinding Cameras With Flashlights. Any Ideas?

I have a problem where people are 'blinding' cameras at night with flashlights in a retirement community. They shine flashlights at the cameras so they cannot see.

Can you buy DVR or NVR with a capability of detecting this and notifying you via text?

How do you deal with this?


Use mirrored domes.

Irritates and illuminates shiners. ;)

Off-axis overlapping coverage would require more sophisticated simultaneous "blindings" to prevent footage that might possibly support recognition of the culprits. This might be viable if it is just one or two sites, but could become expensive if the problem is occurring extensively throughout the facility.

This seems like the easiest solution to me. Add a covert camera covering the same area from a different angle.

Are you using an Analog or IP based system?

Use a thermal camera

Multiple dummy cameras.

Temporary. Peel and stick domes. Keep 'em guessing.

if the camera is with some API control and if the API allow you to enable the ICR (IR Filter) then, just monitor the lux levels and when it exceeds a certain level, enable the IR filter, which would block out IR from the Flash Light, and give you a better image..?

or trigger a relay and switch on a Flood Light to illuminate the whole area, more light than the flash ligh hence camera should pick the images..?

just curious.. why do people do that just for fun or intention to harm / mens rea ..?

Most have the ability to send an email on event. Try and set the motion detection sensitivity to its lowest triggerable setting. Some of the cheaper cameras/DVRs are notoriously finicky so you may have to play with it a bit to just get flashlights. Hopefully you don't have headlights straight into the camera as well.

If you are already using motion detection for something else, you will get emails for everything so...

The Avigilon analytics have a function that can trigger on bright light, then send an email. You can add a Rialto to your system and get this function.

Is ACC necessary as well?

The Rialto is designed to use the Avigilon View software which is no charge. The "Sudden Light change is the analytic you need to set up. Change

I like the ideas of setting an IR filter to come on but may make the rest of the scene even darker at night or it will take too long to readjust, correct?

The idea of setting it to send texts are great but they will be gone by the time you get there.

Having the camera turn on a light is good but it may be a burden to the tenants.

This set up is in a senior community in Florida and kids are coming through and stealing bikes, etc.

I appreciate all the feedback. I cant believe they don't have a quick fix in this industry yet.

Quick fix is to add a discreet camera nearby.

Travis - I believe there is a very simple answer to this question... What you need is a camera with excellent Wide Dynamic Range. That is why I asked earlier if you were using an analog or IP based system. IP cameras tend to have better WDR performance than that of Analog cameras. Either way, you need to replace what you have now with a camera that can compensate for extreme lighting. Here are two links that I recommend you view. Please feel free to contact me if you need assistance with choosing specific model numbers:

If you work for or rep a manufacturer, disclose this up front or the comment will be deleted. Thanks.

Understood. Sorry about that.

I am with FLIR and I don't know if this would help or not. Some of the cameras have a feature called HLC which stands for High Level Contrast and the purpose is to place black circles around head lights and such to prevent the camera from adjusting to that light.

Would it help? I don't know. It was designed for headlights.
