Reverse Peephole Security: Protecting Your Privacy with Peephole Covers

Peephole Security

Peephole security is a real thing, especially when it comes to situations out of your control, like hotel rooms. It’s often neglected within the overall security picture, but nevertheless it’s something that you should consider.

Why should you worry about peephole security? Because products like Reverse Peephole Viewers exist and are easily obtainable by anyone. These viewers, when placed over the outward facing side of a peephole, allow the user to view what’s on the other side by realigning the otherwise unviewable lenses.

To counter the threat of reverse peephole viewers, today we’ll be taking a look at a few commercially available products to help you to determine which might be the best for your situation.

Defeating The Reverse Peephole Threat

Not to be confused with the Seinfield episode where Kramer reverses the peephole on his door on purpose so that “if somebody want’s to help themselves to an eyeful, we say enjoy the show.” A reverse peephole viewer is a bit on the pricey side, but as mentioned, easily obtainable by anyone.

I purchased a couple of solutions for this threat online a few months back and will share my pros and cons of each below. Basically, there’s two categories that these devices fall into, permanent and portable. Let’s first look at portable.

Portable Solutions

Privacy Logic is a company I stumbled onto while searching online and I really like their product offering. They offer a set of two SPEYEGUARD Portable Peephole Covers that simply slip into your existing peephole. The set of two will cover the most common peephole diameters of 3/8″ and 5/8″. Everything I’ve come across so far, has been able to fit these size covers. The top and bottom of the covers have cutouts that enable you to grasp the device to quickly remove it for a peek and easily reinsert it.

They’re made of ABS plastic and built well in the USA. The tabs that insert into the peephole are flexible enough to withstand multiple uses and still retain their functionality. Check out Privacy Logic for more information and to purchase these Portable Peephole Covers.

Permanent Solutions

To start off the two products we’ll be looking at in the permanent category, Privacy Logic also offers the SPEYEGUARD Stationary Peephole Cover. The backplate of this cover mounts to the door via a top and bottom mounting screw. The top cover locks into place on a ramp, which allows it to easily slide up and down as needed.

I did find that pilot holes are needed before attempting to simply screw the backplate in place on a door, that or a nail punch is what Privacy Logic suggests in the installation instructions. I really liked the functionality of this device and it’s a good solution. Plus, all Privacy Logic products are made in the USA.

The second product we’ll take a look at in the permanent category is the SecureAview Peephole Cover, which is a pendulum style cover that mounts with one screw above the peephole.

This was a bit simpler to mount than the Privacy Logic permanent solution, but I don’t care for the fact that the spacers it comes with don’t allow you to adjust the tension that the cover has. This causes it to swing unnecessarily when you let it go. It also makes quite a bit of noise when opening and closing the door due to the swinging. I’m sure this could all be fixed by simply having a thin rubber washer added between the cover and the metal washer.

What I also didn’t care for, was that because the device doesn’t sit flush against the peephole, there’s visible light that could be seen by someone with a reverse peephole viewer. The only reason I mention this is movement on the other side of the door could be detected by the viewable light.

I do think the all-metal construction is great on the SecureAview product and I really like the attention to detail of including a matching adhesive cover to apply over the screw during installation. To learn more or pick up a peephole cover from SecureAview, click here.

Notes

A great tip that the SecureAview website shared was to ensure your existing peephole is assembled with a little blue loctite (non-permanent) so that it can’t be unscrewed from the outside. They also mention that some people squirt toothpaste in peepholes at a hotel, so as a last resort, you could always do that. Also ensure you check the peephole of any hotel room if it has one and make sure it hasn’t been reversed by the last comedic guest.

While protecting your privacy by covering your peephole might not be on the forefront of your security plan, hopefully you’ve learned a bit from this article about why you should take it seriously.

I always have a roll of electrical tape, 3M by preference, in one pocket or another. It's handy for a variety of problems, and a small piece stuck over a hotel peep hole solves that one, full stop. I am no more paranoid than my neighbors, but a friend who has dodged the bad guys successfully for decades carries a little ten inch periscope when he travels so as not to get something unwelcome in his eye when he hears a knock on the door.

A thumb tack and the plastic lid off a film can is much cheaper

Hate peepholes. Bad guy knocks, looks in peephole and waits for it to darken. Puts pistol to the peephole and fires. No matter what type of cover you are using, look out the peephole from a darkened room.

A spent .45 shell fits in the hole perfectly. The brass makes it look like it belongs there, only a discerning eye will pick up on it.

Electrical tape should be in integral part of the bug out bag. They look in? The lights are out as far as they are concerned... Lo tech wins here

I keep a roll of electrical tape in my travel shaving kit. covering the peephole is on the mental checklist of things to do upon check-in to a hotel.

It seems that everyone has their bases covered and just uses wadded up paper or duct tape. Although, tape can leave a mark and paper still allows light/movement to be seen.

I can see this being useful as a permanent solution so you don't have to tape up your door every time or have to repaint the door on your rental property.

Heck, if I owned a hotel or motel, I'd love to get these installed on every door so guests don't have to deal with it themselves!

I agree with the tape solutions for portability etc etc but if you live in an apartment a more permanent solution may be appropriate.

Especially if your roommate/girlfriend doesn't want a post it note or piece of tape stuck on the door 24/7...

I carry a small roll of gorrilla tape in my EDC. Think that would take of the problem just fine.

Or, as a portable solution, you can just use a adhesive post-it on the peephole.

I am pretty sure someone has already mentioned this but dont forget about the redneck version using duct tape.

Here are my 2cents on this topic, I find it ridiculous to pay for any of those devices especially for the "portable" kind given that using a couple of post it notes, or a small piece of paper , napkin, etc and a little bit of tape, you could cover all the peepholes in a hotel room and one can also use a pen cap, and although they might not be as aesthetically pleasing, why spend $8-15 when one probably already has a pen cap or post it notes laying around anyway? What I'm trying to say is that all this products are an overengineered way to solve a very simple problem, when a lot of cheaper alternatives are available.

I'm with you, Mike. I'd prefer to keep the door and peep hole looking clean and functional. Plus, if anyone comes over and sees the backside of the peep hole it will still look aesthetically pleasing. I'm not a fan of post-its or duct tape just hanging around my house.

While you can certainly do it with a piece of paper the one major reason to buy something like this is because you have a wife who put up with tape/paper on all of the peepholes.
