Bullet vs dome camera: same sensors, different strengths. Mounting, deterrence, night vision and vandal resistance compared, plus turret cameras.
Bullet camera or dome camera? It is the most common camera question in surveillance buying, and one of the most often answered badly. Vendors steer buyers towards whatever they sell most. Installers fit whatever is on the shelf. And marketing makes the two sound far more different than they are.
The straight answer: bullet and dome cameras use the same technology inside, the same sensors, compression, ONVIF and RTSP support and often the same firmware. Choosing between them is about mounting, deterrence, environment and vandal resistance, not picture quality or AI. A third type, the turret camera, often beats both indoors and is routinely left out of comparisons.
This guide explains each type, where each genuinely wins, the factors that matter at scale, how AI changes the choice, and a simple way to pick the right camera for each location.
A bullet camera has a cylindrical body with the lens at one end, on a bracket you aim. It looks like a small telescope. A dome camera hides its lens under a clear or tinted dome, usually fixed flat to a ceiling or wall. It looks like a smoke detector.
They differ in five ways: mounting, visible deterrence, vandal resistance, night vision behaviour in poor conditions, and installation effort. They do not differ meaningfully in picture quality, compression, resolution, low light performance, AI compatibility or how they connect to your video platform.
A bullet camera is a long, weatherproof housing with a visible lens at one end, on a bracket that lets the installer aim it precisely. Enterprise models usually carry an IP66 or IP67 weather rating, with infrared lights built in around the lens.
Where bullets win:
Long lenses. The long housing takes zoom and telephoto lenses naturally, so bullets excel on perimeters, car parks, roads and long corridors.
Visible deterrence. Everyone can see exactly where a bullet camera is pointing. That helps at entrances, loading bays and ATMs, though it can be a drawback where you want aim to stay discreet.
Night reach and cold weather. The larger housing fits stronger infrared lights for longer night vision reach, and avoids the fogging and internal reflections domes can suffer in the cold.
Retrofits. Most existing outdoor brackets, from old analogue or early IP systems, take bullets easily.
Where bullets are the wrong choice: shop floors where cameras should feel unobtrusive; dense ceiling layouts, where bullets look industrial; spots where aim must change often, since a bullet needs a ladder; and vandal prone locations, where the exposed bracket is a target.
A dome camera is a compact housing with the lens under a clear or tinted dome, usually fixed flat to a ceiling. Vandal resistant models use an IK10 rated dome that withstands heavy impact, with infrared lights behind the dome.
Where domes win:
Smart interiors. Shops, hotels, offices, restaurants, schools and hospitals benefit from the low profile look. Retail chains that specify camera appearance as part of store design usually choose domes.
Vandal resistance. IK10 domes resist attack far better than bullets: no exposed lens, no bracket to grab, nothing to prise off. Public spaces, transit hubs, schools and prisons standardise on them.
Hidden aim. A tinted dome does not reveal where it is pointing, so people cannot plan around blind spots. Valuable for retail loss prevention and gaming floors.
Dense ceilings. Several domes close together look tidy; the same number of bullets looks industrial.
Where domes are the wrong choice: long lens applications, cold outdoor spots where the dome fogs or reflects infrared, and places where the aim must change often (unless you use a PTZ dome).
The turret camera, also called an eyeball camera or mini dome, is common in enterprise projects and often the right answer where buyers were choosing between bullet and dome by habit.
It has a ball shaped lens in a shallow housing, fixed flat to a wall or ceiling like a dome, but the lens swivels inside for aiming. No protruding lens like a bullet, and no full dome to fog or reflect.
Where turrets win:
Cleaner night pictures. With no curved dome in front of the lens, infrared light does not bounce back into the camera, so night pictures are usually clearer than a dome's.
Compact and discreet. Even smaller than a dome, and unobtrusive in offices, shops and hotels.
Easy aiming without exposure. Bullet style aiming with none of the bullet's vandal exposure.
Value. Usually priced like domes, with a simpler mechanical design.
For most indoor and sheltered outdoor locations where visible aim is not needed as a deterrent, the turret is the right default.
The specifications that decide success are mostly independent of the housing. Buyers who choose the housing first and the specifications second usually choose wrong.
Sensor size. The single most important specification. A larger sensor sees far better in low light than a smaller one at the same resolution, whatever housing it sits in.
Resolution and frame rate. 2MP, 4MP, 5MP and 4K are available in both bullets and domes from every major maker.
Compression. H.264 and H.265 support is a firmware feature, identical across a maker's bullets and domes. H.265 is standard on enterprise cameras and saves a great deal of bandwidth and storage.
ONVIF support. Profile S (streaming), Profile G (recording) and Profile T (advanced video) are firmware features too, not housing features.
Power. Both types usually run on PoE over one network cable. Standard PoE suits basic models; PoE+ is needed for strong infrared, heaters or PTZ motors.
Wide dynamic range. A sensor and processing feature available in both types.
Infrared reach. The one specification where the housing really matters: bullets generally reach much further at night because they fit larger infrared lights.
Vandal and weather ratings. IK10 domes resist attack best; both types come in IP66 and IP67 outdoor versions.
AI works on the picture a camera produces, not on its housing. With the same sensor, resolution and lens, bullets, domes and turrets give AI identical input. But the housing influences results indirectly in three ways.
Field of view. Long lens bullets produce narrow views that pack detail onto a smaller area, which helps face recognition and number plate recognition, both of which need enough pixels on the face or plate. Long range perimeter bullets with long lenses consistently outperform domes at the same distance for these tasks.
Mounting height and angle. Ceiling mounted domes and turrets give overhead or angled views that suit object detection, person tracking, unique person counting, crowd detection, PPE detection, line crossing and intrusion detection. Wall mounted bullets give more side on views that suit face recognition at approach and are less suited to overhead analytics such as heat maps.
Night picture quality. AI performs best on clean pictures. Turrets without dome reflection and bullets with strong infrared give cleaner night footage; a dirty or fogged dome is the worst case.
So, choosing with AI in mind: bullets for long range face and number plate recognition; turrets for indoor detection, tracking and crowd analytics; domes for smart interiors where a turret is not acceptable to the architect.
A good video platform treats every camera type identically, so above the connection the housing is invisible. At scale, though, the practical economics differ in ways comparisons rarely mention.
Power budget. Outdoor bullets with strong infrared and heaters often need PoE+, which affects switch choice. Indoor domes and turrets usually stay within standard PoE.
Installation effort. Bullets mount on brackets that need careful aiming. Domes and turrets mount flat with little adjustment, so they are usually quicker to fit. On estates of hundreds of cameras, that adds up.
Cleaning. Domes need their covers cleaned to stay clear. Bullets need their front glass cleaned. Turrets have the smallest surface and usually need the least attention.
Staying on target. Bullet aim can drift with wind, temperature changes or knocks. Domes and turrets aim internally and hold position. Fleet wide realignment is a bullet problem.
Swapping a failed camera. A bullet can usually be swapped without touching cabling or brackets; domes and turrets often take longer because the mount and cable termination sit together.
Over the life of an estate, the most economical pattern is usually turrets indoors, domes in vandal prone public areas and bullets on long range exteriors.
Choose a bullet when: the camera is outdoors and needs a longer lens; you are covering a perimeter, car park, road or long corridor; you need long infrared reach; visible aim helps deter; the climate is cold; or you are reusing outdoor brackets.
Choose a dome when: vandalism is a real risk and you need IK10 impact resistance; hidden aim helps; the interior demands a low profile look; ceiling mounting is preferred; and standard indoor infrared reach is enough.
Choose a turret when: it is a standard office, shop or hotel location; you want the cleanest night pictures; you need flexible aiming without vandal exposure; or value matters and a dome adds nothing.
The best estates mix all three, chosen location by location, rather than standardising on one type everywhere.
Visylix is an automated AI video surveillance platform built in India. It watches every camera with AI, decides what matters, and acts, whatever the housing.
Every camera, every brand. Visylix connects bullets, domes, turrets, PTZ and fisheye cameras alike over ONVIF Profiles S, G and T and over RTSP, with device packs for the top five camera brands. Its native streaming engine also takes RTMP, SRT, NDI and GB28181 feeds, 13+ protocols in all, so even unusual sources fit in.
AI tuned to every location. Visylix runs 22 AI analytics built in house, with detection zones set per camera and per analytic. A perimeter bullet can run intrusion detection and number plate recognition; a warehouse turret can run PPE detection, intrusion zones and line crossing; a retail dome can run heat maps and unique person counting; a ceiling fisheye can run crowd detection across the full circle. Each camera learns its own normal, and small, distant subjects are still detected, which is exactly what long range bullets need.

Bullet and dome cameras share the same sensors, compression, ONVIF support and platform compatibility. The choice is about mounting, deterrence, environment and vandal resistance, not picture quality or AI.
Turret cameras are the overlooked third option and the best default for most indoor and sheltered locations.
Bullets win on long range exteriors with long lenses and long infrared reach. Domes win in vandal prone public areas, smart interiors and where aim should stay hidden.
Mix all three, chosen location by location, and run them on a platform that treats every camera the same, so you can choose purely for the site.
Neither is better everywhere; it depends on where the camera goes. Bullet cameras suit outdoor, long range and perimeter coverage where strong night vision reach matters. Dome cameras suit public spaces prone to vandalism, smart interiors and places where the camera's aim should stay hidden. For most offices, shops, hotels and schools, turret cameras, a third type most comparisons skip, often beat both. The best estates mix all three.
Both are good at different jobs. Domes are good indoors, where vandalism is a risk, where looks matter and where a hidden aim helps. Bullets are good outdoors, for long range perimeters, for long night vision reach and where a visible camera deters. Choose by location, not by which type is "better".
Outdoor long range coverage such as fences, car parks, roads and long corridors; long zoom lenses; long infrared reach at night; cold climates, where domes can fog up; places where a visibly aimed camera deters, such as loading bays, ATMs and entrances; and reusing existing outdoor brackets. They suit smart interiors and vandal prone spots less well.
A bullet camera has a cylindrical body with a visible lens on an adjustable bracket. A dome camera hides its lens under a clear or tinted dome, usually fixed flat to a ceiling. They differ in mounting, deterrence, vandal resistance, night vision behaviour and installation effort. They do not differ meaningfully in picture quality, compression, ONVIF support or AI compatibility; the sensor inside is usually identical.
A turret camera, also called an eyeball camera or mini dome, has a ball shaped lens in a shallow housing with no full dome over it. The lens swivels inside the housing for aiming. With no dome to fog or reflect infrared, turrets usually give cleaner night pictures than domes, at a similar price. They are the right default for most indoor and sheltered outdoor locations.
Usually not. Bullets generally suit outdoor use better: they take longer zoom lenses, reach further with infrared at night, avoid dome fogging and reflection in cold weather, and their visible aim deters. Choose a dome outdoors when vandal resistance matters most (IK10 rated domes resist impact very well) or when a low profile look is required.
Generally not. Bullets look industrial in smart interiors and can feel intimidating in customer areas. Dome or turret cameras usually fit better indoors. Bullets make sense indoors for long corridors, warehouse aisles or where a long zoom lens is needed.
It depends on the spot. For long range perimeters, a bullet with a varifocal lens and long infrared reach. For entrances where you need faces or number plates, a bullet with a narrow view that concentrates detail. For sheltered areas such as covered parking where vandalism is a risk, an IK10 vandal dome. All should offer H.265 compression, an IP66 or IP67 weather rating, PoE+ power, ONVIF Profile S and good wide dynamic range.
Yes, and you should. Platforms such as Visylix treat every camera type the same way over ONVIF and RTSP, so you can choose each camera purely for its location. A typical estate uses bullets on the perimeter, domes in vandal prone public areas, turrets in offices and shops, PTZ cameras at key control points and fisheye cameras for open rooms.
Not directly. AI works on the picture, which depends on the sensor, resolution and lens, not the housing. Form factor matters indirectly: long lens bullets concentrate detail for face and number plate recognition; ceiling mounted domes and turrets give the overhead view that suits counting, heat maps and crowd analytics; and turrets usually give cleaner night pictures than domes. Visylix lets you set AI zones per camera and per analytic, so every camera type is tuned to its spot.
