Quick Answer
Bullets and domes are not the good and better versions of one thing. They fail differently. A bullet points visibly at whatever it is watching, which deters, and it keeps its lens and infrared ring out in open air, so it never fogs itself at night. A dome hides its aim behind a bubble and, in a vandal-rated version, survives a hit — but that same bubble is what turns the camera’s own infrared into a haze once dirt, water spots, or a badly seated foam ring get involved. The option most comparisons skip, the turret or eyeball, keeps the dome’s low profile and drops the bubble entirely, which removes the infrared problem at the shape level. For an exposed outdoor wall, start with a bullet or a turret. Save the dome for a ceiling, a soffit, or anywhere the public can reach the camera.
What the Three Shapes Actually Are
Most people arrive at this decision the same way: a dome looks tidier on a house, so they buy domes for everything, mount one on an exposed wall facing the driveway, and then spend a month wondering why the night footage looks like it was shot through a shower door. That is not a defective camera. It is a shape doing exactly what its shape does, in a spot it was not designed for.
A bullet camera is the cylindrical one, shaped roughly like a rifle cartridge and typically two to eight inches long. Most use a fixed or varifocal lens built for a specific throw distance rather than broad coverage, which is why a bullet usually ends up watching one approach — a driveway, a gate, an alley — rather than a wide open area.
A dome camera takes its name from the housing that covers the lens. It is normally mounted on a ceiling, eave, or soffit, indoors or out, and a vandal-resistant version pairs a solid metal base with a polycarbonate cover built to survive a direct hit without cracking. Our dome camera roundup covers which specific models are worth the money once you have decided the shape is right.
A turret camera — also sold as an eyeball camera or a flat-faced dome — uses a ball-and-socket design that lets the lens swivel freely inside its mount. It gives you the easy angle adjustment of a bullet with the low-profile look of a dome, without the bubble that causes glare. One practical consequence worth knowing before you commit: because a compact rounded body makes it hard to add external Wi-Fi antennas without compromising the weather sealing, the large majority of turrets are Power over Ethernet cameras. Choosing a turret often quietly chooses a wired install too.
One thing shape does not decide, despite how often it is presented that way, is field of view. Bullets typically run about 80° to 105° and domes about 80° to 145°, but the exact number depends on the specific lens and sensor rather than the housing, so the spec sheet settles it and the silhouette does not.
The Night-Vision Problem That Settles Most of This
If you only read one section, read this one. It is the difference that shows up in real footage, and it is the one almost nobody thinks about at the point of purchase.
Every one of these cameras sees in the dark the same way: it fires its own infrared light out into the scene and reads what comes back. Axis Communications, which publishes an engineering white paper specifically on this failure, describes what goes wrong when some of that light never makes it out — part of it reflects back into the camera, introducing foggy or blurry effects in the image, or mirror effects in the dome itself, and the result can be a severely reduced image. Axis names three causes: objects close to the camera such as walls or poles, water droplets or dirt or dust sitting on the dome, and external light sources aimed at the camera.
The bullet and the turret put their infrared ring in open air. The dome puts it under the same bubble as the lens, which is the surface every night-vision complaint about domes traces back to.The second cause is the one a dome owns and a bullet does not. A bullet can absolutely glare off a nearby white soffit or a wet wall — that is the first cause, and it applies to any camera with infrared LEDs. What the dome adds is a second reflective surface sitting a few centimeters in front of the lens, permanently, in the exact path the light has to travel twice. Reolink describes the symptom plainly: dome cameras can develop an internal infrared halo at night if dust or moisture collects on the housing, and it is worse on models built without a foam seal around the lens.
Speco Technologies, whose support desk deals with this often enough to have written a dedicated troubleshooting article, is blunter about the single worst version: the most severe infrared reflection cases come from the foam gasket ring not being pressed firmly against the dome cover, which creates a halo effect. The fix is to make sure the dome bubble sits snug against the foam ring, and Speco notes that when the contact is good, the ring looks slightly squashed. Axis makes the same point from the other direction: do not remove or damage the rubber ring around the lens, because it needs to touch the dome, and the more you tilt the lens, the higher the risk of infrared leaking across that seal.
Five Ways a Dome Turns Its Own Infrared Against Itself
1
Foam ring not seated
The gasket has to be squashed flat against the bubble. A gap is the single worst case, and it produces the classic halo.
2
Dirt, dust, or water on the bubble
Reflects the camera’s own light back in. Daytime video can look perfectly fine while night video is ruined.
3
A wall, eave, or ceiling in the beam
Ubiquiti tells installers to keep infrared cameras at least 24 inches, or 60 centimeters, from neighboring walls and the ceiling.
4
Too much lens tilt
Tilting the lens to reach a view raises the odds of light leaking past the seal. Tilt as little as the mount allows.
5
The cover put back on wrong
Dome covers lock to make an airtight seal. A cover that is not attached properly reflects infrared straight back into the lens.
None of these show up on a spec sheet. All five are install-time decisions.
This is exactly the problem the turret shape removes. A turret has a flat, exposed lens face and no outer shell over it, so there is nothing in front of the LEDs to reflect off. It is not a settings fix or a better foam ring; it is the reflective surface being deleted. If you want the broader picture of how infrared range, spotlights, and color night modes interact, our guide to how camera night vision actually works goes deeper than shape alone.
One honest limit on that claim. Manufacturers describing turrets as “completely free” of infrared glare are describing the bubble problem only. A turret still sits in the world: aim it at a white wall three feet away and it will still wash out, because that is Axis’s first cause and no shape fixes it. The turret removes one of three causes. It is the one you cannot clean your way out of.
Visibility Cuts Both Ways
The standard framing is that bullets deter because they are obvious and domes are better because they are discreet. Both halves of that are true, and both have a cost that rarely gets mentioned alongside them.
What Each Shape Tells Someone Standing In Front of It
👁️ A bullet announces itself
- Unmistakably a camera from the sidewalk, and pointed at something specific
- Anyone can see what it covers — which also shows them where it does not
- If it gets knocked out of alignment, you can tell at a glance from the ground
- Easy to reach, so installers generally mount bullets 8 to 10 feet up, sometimes 12 where tampering is a real concern
🔽 A dome keeps its aim to itself
- The housing conceals which way the lens is pointing
- Harder to grab or redirect than a body on an exposed bracket
- Reads as low-profile rather than hostile on a house or a storefront
- You cannot confirm from the ground that it is still aimed where you left it
That last line is the point people miss. A dome’s concealed aim is genuinely useful against someone casing a property, but it works on you too. A bullet nudged sideways by a ladder, a gutter cleaner, or a strong storm is obvious the next time you walk past. A dome nudged the same way looks identical from the ground and you find out weeks later, when you go looking for footage of something and the frame is half fence. If you go with domes, get in the habit of checking the live view after any work near them, and use our room-by-room camera placement walkthrough to decide what each one should be framing in the first place.
It is also worth being honest that deterrence only works when the camera is seen. A dome tucked up into a soffit is doing nothing to change anyone’s mind about your front door, because nobody looked up. If deterrence is the actual job — a long driveway or an open side yard where you want people to decide against walking in — the bullet shape is not a compromise, it is the feature.
Vandal Resistance, and What IK Actually Measures
“Vandal-proof” is printed on a lot of dome listings, and it does mean something specific. The IK rating scale specifies degrees of protection against external mechanical impact, measured in joules, and the test parameters — impact energy, mass, and drop height — are set out in the international standard IEC/EN 62262.
What the Two Ratings You Will Actually See Mean
20 J
IK10: a 5 kg mass dropped from 400 mm onto the housing
5 J
IK08: 1.7 kg dropped from 300 mm — a quarter of IK10’s energy
IK01–IK10
the full published scale, low to high
8–10 ft
the mounting height that keeps a camera out of casual reach
IEC/EN 62262 defines one standardized blow with a set mass and drop height. That is a useful, comparable number, and it is not the same thing as surviving a determined attack.
This is the one category where the dome is not just an aesthetic preference. Reolink’s own buying guidance is sensible about when to pay for it: look for an IK10 rating if the camera covers a spot the public can reach, like a storefront entrance or a shared hallway, and skip it for a covered porch or a low-traffic indoor room and put the budget elsewhere. If you are securing a business or a public-facing entrance, that is the situation the vandal dome exists for.
Here is the wrinkle nobody puts in a comparison table. If you go looking for a vandal-rated turret — the shape that was supposed to have no bubble — what you will often find is a hybrid. Reolink’s own turret guide recommends, as its heavy-duty vandal pick, a camera it describes as a turret-style dome with a reinforced clear dome and a certified IK10 rating. That is not a contradiction on the manufacturer’s part, it is the physics: an armored cover over the lens is what an impact rating buys, and once there is a cover over the lens, the infrared has a surface to bounce off again. Vandal resistance and glare-free infrared pull in opposite directions. You can have a compromise, and plenty of good cameras are one, but you cannot have both at full strength in the same housing.
Mounting Angle and the Cleaning You Will Actually Do
Shape decides where a camera wants to be bolted, and it decides what you will be wiping off it for the next five years. Both are worth more thought than they normally get.
Outdoor domes are designed primarily for downward, ceiling-mounted installation, and they stay cleaner in that orientation. Mounted vertically on a wall, they collect dirt and water spots far more readily, which feeds straight back into the glare problem above — and Reolink’s own conclusion is that if wall mounting is required, a bullet is often the more practical choice. That single line resolves most of the arguments people have about this. A soffit, an eave, or a porch ceiling is dome territory. A bare wall facing the weather is not.
Axis adds the maintenance half: place the camera where it is as little exposed to the weather as possible, clean the dome regularly with a mild soap detergent, water, and a soft microfiber cloth to avoid scratching it, and, if water droplets are a recurring problem, a water-repellent spray of the kind used on motorcycle visors can help. Speco’s guidance is stricter on chemicals: use a lint-free, non-abrasive cloth and never harsh agents, because acetone, alcohol, and household glass cleaners can damage lens coatings. The two are not really in conflict — both say soft cloth and no solvents — but the difference is a good reason to read your own model’s manual before reaching for anything stronger than water.
| What goes wrong over time | Bullet | Dome | Turret |
|---|
| Spider web across the lens | Common. Spiders are drawn to the warmth of the infrared ring right at the lens edge | Rare. The lens sits behind a sealed cover | Rare. A flat face gives a web nothing to anchor to |
| Infrared halo at night | No bubble to bounce off, though nearby walls still can | The known weak point: dust, water spots, or a loose foam ring | Removed at the shape level — no cover over the lens |
| Knocked out of alignment | Easier to grab and re-aim, which is why height matters | Hardest to redirect by hand | The ball moves by hand, so it can be pushed off aim |
| Cracked or smashed housing | Least protected of the three | Best protected, if it carries a real IK rating | Usually skips the reinforced shell a dome has |
| Routine cleaning | Wipe the lens every few weeks in warm months, more often near plants | Whole bubble, carefully, with the right cloth | Flat face wipes clean in seconds |
Two small install habits are worth adopting whichever shape you buy. Keep the protective film on the dome until the very end of the job, and avoid touching the bubble — a fingerprint leaves grease that will not affect the daytime image at all but shows up immediately at night. Then actually take that film off once you are happy with the angle, because leaving it on produces the same glare you were trying to avoid. Dirt, dust, and fingerprints on the glass all cause infrared light to bounce back into the lens, and it is a startlingly common cause of a camera that seemed fine on day one.
A related payoff: the spider-web problem is not only a picture-quality issue. A web strung across a bullet’s lens catches the infrared and drifts in the wind, which is a reliable source of motion alerts at three in the morning. If that sounds familiar, our piece on why cameras keep recording things you do not care about covers the rest of the false-alert causes.
Which Shape Belongs Where
Matching shape to location is most of this decision. The table below is the short version, built from the mounting, glare, and vandal points above rather than from what each shape looks like on a house.
| Where it is going | Shape to start with | Why, and what to watch |
|---|
| Covered porch or front-door soffit | Dome or turret | Sheltered and ceiling-mounted, which is the orientation a dome is designed for. Keep the beam clear of the porch ceiling |
| Exposed wall facing a driveway | Bullet | Wall mounting is where domes collect water spots and glare, and it is a spot where being seen is useful |
| Eave or soffit over an open yard | Turret | Ceiling-mount discretion without the bubble, and the easiest of the three to re-aim by hand |
| Storefront, lobby, or shared hallway | Vandal-rated dome | The one case where an IK10 housing earns its cost, because the public can reach it |
| Long approach or perimeter fence line | Bullet | Built for a single long throw rather than broad coverage, and often available with optical zoom |
| High warehouse or shop ceiling | Dome or turret | Out of reach anyway, and a ceiling mount keeps the housing cleaner |
| Indoor room in a lived-in house | Dome or turret | Low profile matters more than deterrence indoors, and there is no weather to fight |
Notice that the turret appears in three of those seven rows and is the outright answer in one. That is not an accident of this article. Both of the manufacturer guides cited throughout it describe the turret as the shape installers increasingly reach for on outdoor jobs, which is why leaving it out of a bullet-versus-dome comparison makes the comparison worse than it needs to be. If you are laying out a multi-camera install, our wired camera system guide covers the recorder and cabling side of the same decision.
Where Shape Stops Mattering
Having spent a whole article on shape, it is worth marking the line where it stops being the thing that decides your footage.
Night-vision range is not a shape property. Reolink lists both bullet and dome cameras at up to roughly 100 feet of infrared range, because range comes from how much infrared the camera puts out and how sensitive its sensor is, not from the housing around it. Field of view is not a shape property either, as covered earlier: the ranges overlap heavily and the lens decides. Resolution obviously is not. If detail at distance is what you actually need, that is a lens and sensor question, and our 4K camera guide is the more useful place to spend your attention.
So the honest hierarchy is this. Pick the shape by where the camera is going and what the night image has to survive there. Pick the model by resolution, lens, and how the footage gets stored. Getting the shape wrong costs you a foggy night image or a camera you cannot keep clean; getting the model wrong costs you a clear picture of someone you still cannot identify. Both are worth avoiding, and only one of them is what this page is about.
Final Recommendation
If you are buying one outdoor camera and you do not already know which shape you want, buy a turret. It gives you the dome’s low profile and the bullet’s easy aiming, and it deletes the single most common night-vision complaint in this whole category rather than asking you to manage it with cleaning and careful cover reassembly. Expect it to be a Power over Ethernet camera, and plan the cable run before you buy.
Three things would change that answer. If the camera will hang somewhere the public can walk up and hit it — a storefront, a shared entry, a low carport — buy a vandal-rated dome instead and accept that you are signing up for bubble cleaning as the price of the IK10 housing. If the point of the camera is that people see it and change their minds, buy a bullet, mount it 8 to 10 feet up so it cannot be swatted out of aim, and put wiping the lens on your calendar for the warm months. And if the camera is going on an exposed wall rather than under something, skip the dome regardless of how it looks — that orientation is where domes collect the water spots that cause the glare in the first place.
Whichever way you go, do one thing on install day: check the live view after dark, from the final mounting position, before you tidy the ladder away. Every failure in this article is invisible at noon and obvious at midnight. If you are still deciding how many cameras and where, start with the placement walkthrough and work back to shapes from there.

Frequently Asked Questions
Are dome cameras better than bullet cameras?
Neither is better in general. A dome is better on a ceiling, a soffit, or anywhere the public can reach the camera, because it is discreet and can be bought with a real impact rating. A bullet is better on an exposed wall, on a long approach, and anywhere you want the camera to be seen. The mistake is treating them as tiers of the same product rather than two different tools.
Do all dome cameras get infrared glare?
No, but all of them can. The dome bubble is the surface the camera’s own infrared can bounce off, so a clean bubble, a properly seated foam ring, a correctly locked cover, and clearance from nearby walls will keep a good dome looking fine. The point is that a dome asks you to maintain those conditions, and a bullet or turret does not.
What is a turret camera called on a spec sheet?
Turret, eyeball, or flat-faced dome, depending on the brand. Some manufacturers file them under dome cameras in their own catalogs, so it is worth looking at the product photo rather than trusting the category name. If the lens sits behind a clear bubble, it is a dome for the purposes of everything in this article, whatever the listing calls it.
Can a dome camera go outside?
Yes, as long as it carries an outdoor weather rating, and it will do best mounted downward under a ceiling, eave, or soffit rather than flat on an exposed wall. Wall-mounted outdoor domes collect water spots and dirt faster, and that debris is what turns into night glare.
Does a smoked or tinted dome fix the glare?
It reduces the visual impact of reflections rather than preventing them, and camera makers offer lightly tinted domes for exactly that reason. It is a mitigation, not a cure, and a tint also sits in the light path in daylight. Treat it as a nice-to-have on a dome you have already decided to buy, not as a reason to choose a dome over a turret.
Why does my camera look fine in the day and foggy at night?
That pattern almost always means the camera’s own infrared is reflecting back into the lens. Fingerprints, dust, a water film, a cover that was not clicked fully home, or a foam gasket that is not squashed flat against the bubble are the usual causes. Daylight does not need the camera’s own light source, so none of it shows until the infrared switches on.
Will a visible bullet camera actually deter anyone?
A camera that is obviously a camera changes some people’s plans, which is the whole argument for the bullet shape. It also tells anyone paying attention exactly what is covered and what is not, so treat visible deterrence as one layer rather than the plan. Position matters more than shape here: a camera nobody looks at deters nobody.
How do I stop spiders webbing my bullet camera?
You mostly manage it rather than stopping it, because what attracts them is the warmth of the infrared ring itself. Wiping the lens ring every few weeks through the warm months is the practical answer, and keeping the camera away from plants and cluttered eaves helps. If it is driving constant false alerts, a turret is the shape that makes the problem structural rather than seasonal.
Does camera shape affect video quality?
Only at night, and only through reflections. Resolution, lens, aperture, and sensor decide your daytime image, and two cameras with identical internals in a bullet and a dome housing will look the same in daylight. After dark, the housing starts to matter, which is why shape is worth deciding deliberately rather than by looks.
