Dome camera vs Bullet camera.
A dome camera sits in a low-profile hemispherical housing and suits ceiling-mounted, public-facing and reachable positions where tamper resistance and a discreet profile matter.
Quick answer — when to choose Dome camera or Bullet camera
Quick answer
A dome camera sits in a low-profile hemispherical housing and suits ceiling-mounted, public-facing and reachable positions where tamper resistance and a discreet profile matter. A bullet camera sits in a cylindrical housing on an adjustable arm and suits wall, column and pole positions outdoors, where visible deterrence and longer lens or infrared reach matter. The housing does not determine image quality — sensor, lens, lighting and configuration do. In practice the choice follows the mounting surface, the reachability of the position and whether the camera should be discreet or obvious. On many current designs a turret camera is the better answer than either, because it keeps the compact profile without the bubble that causes infrared reflection.
When to use
You are selecting camera bodies for known positions and want each housing matched to its mounting surface, exposure and servicing reality.
When not to use
The question is how many cameras a site needs or how much storage they will consume — those follow a coverage and retention study, not a housing choice.
Option A
Dome camera
A camera in a low-profile hemispherical housing, usually ceiling or soffit mounted, with the lens aimed inside a fixed bubble so the direction it faces is not obvious from below.
Choose Dome camera when
- The camera sits within reach of the public and vandal or tamper resistance matters
- The interior is guest-facing and a discreet, flush ceiling profile is wanted
- The mounting surface is a ceiling or soffit rather than a wall or column
Option B
Bullet camera
A camera in a cylindrical housing on an adjustable arm, usually wall or pole mounted, where the direction it faces is visible and the lens sits behind its own shroud rather than a bubble.
Choose Bullet camera when
- The position is outdoors, at height, on a wall, column or pole
- A visible deterrent is wanted rather than a discreet one
- The view needs a longer lens or a longer infrared reach along an approach
Side by side
The fields that decide it
| Dimension | Dome | Bullet |
|---|---|---|
| Typical mounting | Ceiling and soffit | Wall, column, pole and eave |
| Profile | Low and flush; aiming direction not obvious from below | Protruding and directional; aiming direction visible |
| Deterrence | Discreet — presence read, direction not | Overt — a visible statement that the area is watched |
| Tamper and impact resistance | Usually the stronger option; impact-rated variants are common | The body is robust but the arm and aim are exposed to interference |
| Infrared behaviour | The bubble can reflect infrared internally if the seal or shroud is disturbed | Illuminators sit outside the lens path, so internal reflection is not the failure mode |
| Aiming and re-aiming | Set inside the housing; the bubble usually has to come off | Adjusted on the external arm without opening the camera |
| Weather and debris | Bubble sheds rain but shows dust, spider webs and water spotting | Integral shroud sheds rain and shades the lens on exposed runs |
| Cleaning burden | Bubble needs periodic cleaning to hold image quality | Front glass is smaller and generally less prone to spotting |
Turret cameras — an open ball in a compact base, sometimes called eyeball or flat-face — are worth considering alongside both. They keep the dome's compact profile and the bullet's freedom from bubble reflection, which is why they have become the default on many interior and sheltered exterior positions.
Before the drawings freeze
What changes at design stage
What changes at design stage
- Decide the mounting surface before the housing. A ceiling position and a pole position impose different bodies, and choosing the camera first tends to produce brackets that do not suit the structure.
- Establish the low-light strategy per position. Whether the scene has usable ambient light, needs infrared or needs white light changes the housing choice more than the label on the box does.
- Confirm reachability. A camera within reach of the public is a different specification from one at height, and impact rating is a specification line rather than an assumption.
Infrastructure implications
- Both housings are usually powered over the structured cabling on an IP design, so the switch, the power budget and the cable route are part of the camera decision.
- External positions need the pathway, gland and drip-loop detail agreed with the electrical and civil packages; the housing rating means little if water enters through the cable entry.
- Positions at height need a documented safe means of access for servicing; a camera that cannot be reached safely will not be cleaned or re-aimed.
Getting it built
Coordination & integration
Coordination for architects & consultants
- Agree the mounting substrate with the architect and the structural package early — plasterboard, exposed soffit, glazing mullion and pole each need a different fixing.
- Coordinate infrared and white-light strategy with the lighting design so the surveillance layer and the lighting scheme are not solving the same problem twice.
- Confirm cleaning and re-aiming access with the facilities team at design stage rather than at handover, because that is what determines whether image quality survives the first year.
Integration considerations
- Housing choice is independent of recording architecture — both bodies exist as analogue and IP cameras, so this decision and the recorder decision are made separately.
- Analytics performance follows the sensor, the lens and the scene, not the housing; a housing choice should never be used to justify an analytics expectation.
- Where cameras integrate with access control or a control-room view, the integration is a function of the camera platform and management software rather than the body style.
Typical project fit
Where each is the right answer
Decision summary
- Hotel corridors, lobbies and other guest-facing interiors
- Favours Dome cameraA dome — the flush ceiling profile suits guest-facing interiors, and the housing tolerates being within reach. Consider a turret where infrared is doing the heavy lifting.
- Perimeter, car park, yard and approach roads
- Favours Bullet cameraA bullet — wall, column and pole mounting, longer lens options, longer infrared reach and an overt deterrent presence suit the exposed perimeter.
- Retail sales floor and back-of-house in one specification
- Favours either optionUsually both: domes or turrets on the sales floor where profile and tamper resistance matter, bullets on service yards and delivery approaches. Consistency of manufacturer and management platform matters more than uniformity of housing.
From the field
Common mistakes
- Treating the housing as a proxy for image quality. Sensor, lens, illumination and configuration decide what the footage is worth; the body decides where the camera can go and how it survives.
- Specifying domes with integral infrared behind a bubble in dusty or humid conditions without planning for cleaning, then attributing the resulting haze and internal reflection to the camera.
- Mounting bullets where they can be reached and turned, which converts a fixed field of view into an unnoticed blind spot.
- Choosing the housing before the mounting surface and the low-light strategy are settled, which is how brackets and illuminators end up improvised on site.
- Ignoring turret cameras entirely, when they frequently resolve the trade-off both of these options are being asked to make.
TechnoGuru engineering perspective
How we specify it
We treat this as a question about the position rather than the product. The housing decides how the camera mounts, how it survives contact and weather, how it behaves with infrared and how easily it can be cleaned and re-aimed for the next decade — and those are the things that determine whether a system still produces usable footage in year three. What the housing does not decide is image quality, which comes from the sensor, the lens, the lighting and the configuration. Where a design would otherwise be forced to choose between a dome's profile and a bullet's freedom from bubble reflection, we will usually propose a turret instead. We do not publish camera positions, coverage geometry or site layouts, so this comparison stays at the level of how each body behaves.

· Frequently asked
Dome vs bullet camera — choosing the camera body for the position —
what people ask first.
Which is better, a dome or a bullet camera?
Neither is better in general — they suit different positions. A dome suits ceiling-mounted, reachable and guest-facing positions where a discreet profile and tamper resistance matter. A bullet suits wall, column and pole positions outdoors where visible deterrence and longer lens or infrared reach matter. Image quality is set by the sensor, lens and lighting, not by the housing, so the housing should be chosen for the position rather than for expected picture quality.
What is the difference between a dome and a bullet camera?
The difference is the housing and how it mounts. A dome is a low-profile hemisphere, usually ceiling mounted, with the lens behind a bubble so the direction it faces is not obvious from below. A bullet is a cylinder on an adjustable arm, usually wall or pole mounted, with the aiming direction plainly visible and the lens under its own shroud rather than a bubble.
What is a turret camera and how does it compare?
A turret camera — also called an eyeball or flat-face camera — is an open ball seated in a compact base. It keeps the dome's small footprint but has no bubble in front of the lens, which removes the internal infrared reflection that domes can suffer, and it is easier to aim. For many interior and sheltered exterior positions it is the better answer than either a dome or a bullet.
Are dome cameras more vandal resistant than bullet cameras?
Usually, for the parts that matter. A dome presents a smooth surface with little to grip and is commonly available in impact-rated variants, whereas a bullet's exposed arm can be grabbed and turned even when the body itself is robust. Impact resistance is a rated specification, so it should be confirmed on the specific model rather than assumed from the shape.
Do dome cameras have problems with infrared at night?
They can. When a dome's integral illuminators sit behind the same bubble as the lens, any dust, scratching, condensation or a disturbed light seal can reflect infrared back into the lens and wash out the image. It is a maintenance and sealing issue rather than a fault, which is why bubbles need periodic cleaning and why turret cameras are often preferred where infrared is doing most of the work.
Can I use bullet cameras indoors and dome cameras outdoors?
Yes — both are made in weather-rated and indoor versions, and the mounting surface usually decides. Bullets are used indoors on walls and in warehouses and plant rooms where profile does not matter; domes are used outdoors under soffits and canopies. What matters is that the model's environmental rating and its cable entry detail suit the position.
Does the camera housing affect video quality?
Not directly. Resolution, low-light performance and detail come from the sensor, the lens, the illumination and the configuration. The housing affects video quality only indirectly, through how well it keeps the optical path clean and how stably it holds the aim — which is why cleaning access and secure mounting matter more to long-term image quality than the shape of the body.
