38mm Cam-block Square Tamper Evident Mobile Phone Stickers - 100 pack

About 38mm Cam-block Stickers for Mobile Phones

Please note this is printed with the Cam-Block logo. If you prefer a plain version, please check out Plain Cam-Block Stickers.

These are square 38mm security stickers that go directly over a phone's camera lens to block it completely. When someone tries to remove one, it leaves a clear VOID message across the face of the sticker so it can't be peeled off, used to take a photo and reapplied without anyone noticing. That tamper-evident feature of these camera security labels is what alerts you to any use of a mobile phone's camera throughout someone's visit to your site.

Built for Multi-Lens Smartphones

The 38mm square format of the cam-block tamper evident sticker has been designed to cover the larger, multi-camera arrays found on current Android and Apple devices. The smaller 25mm x 12mm rectangular cam-block sticker works great for single-lens phones or webcams, so it's worth stocking both types of cam-block sticker to make sure all bases are covered.

What Tamper Evidence Actually Means Here

The adhesive is lo-tack, so it comes off cleanly with no residue left on the lens or camera cover. This ensures that once it's removed, the owner of the phone can continue using their phone's camera without needing to clean it first.

The security comes from what happens to the sticker itself, not the surface. Peel it and the word VOID appears permanently across the design. There's no way to reattach it and have it look undisturbed. For sequential-numbered stickers, each one carries a unique number, so you can cross-reference individuals against their assigned sticker and spot at a glance if anyone has swapped or removed theirs.

Where These Get Used

Cam-block stickers are used at any event or venue where guests need their phone for emergencies or payments but camera use needs to be controlled. The sticker lets the phone keep working normally; it just blocks the lens, so common applications include:

• Manufacturing facilities
• Ministry of Defence sites
• Automotive track days and testing
• Fashion events
• Film and TV sets
• Private events

Frequently Asked Questions

Do these stickers leave any mark on the camera lens when removed?

No. The lo-tack adhesive is designed to come off cleanly without leaving residue on the lens or surrounding surface. The VOID display appears on the sticker itself, not the device.

Can someone remove the sticker, take photos and put it back on?

They can but once peeled, the sticker permanently shows VOID across its face and can't be reapplied in a way that looks intact. So, the evidence that the sticker has been removed is clear and visible if anyone attempts it.

Can I choose a specific sequential number range for pre-printed stickers?

Not for stock orders. The number sequence picks up from wherever the previous fulfilled order left off. If you need specific ranges, you'll need a custom print run, which we are more than happy to help with. Please get in touch with our team if specific sequential numbering is something you need.

Will the 38mm size work on all phones?

It's sized for modern smartphones with larger or multi-lens rear camera arrays. For single-lens devices or webcams, the smaller 25mm x 12mm rectangular sticker may suit better. If you're stocking up, it's worth getting a pack of both to ensure that any camera that comes on site can be blocked.

What devices can these be used on?

Mobile phones, tablets, laptops, MacBooks and compact cameras. Simply clean the surface around the lens before applying to get the best adhesion and keep your site protected from unauthorised photography.

Can I get these with our company logo on them?

Yes. Personalised stickers with your logo, branding and custom sequential numbering are available, with a minimum order of 1,000 stickers. Email sales@plastic-id.com or call 0203 744 233 for a quote.
