Turret vs Bullet Cameras for a Factory Floor: Which Goes Where
On a shop floor, use turret (eyeball) cameras on ceilings over open work areas — they resist infrared glare and re-aim at any angle — and bullet cameras on walls, gates and perimeters, where their long IR reach and visible shape deter intruders. Dome cameras suit vandal-prone, low-clearance spots. Match the housing to the zone, not the whole plant to one type.
Most mid-size Indian factories buy one camera type in bulk and mount it everywhere. That wastes money and leaves blind spots. Turret, bullet and dome cameras each solve a different problem. This guide explains what separates them — IR glare, coverage, deterrence, mounting and vandal resistance — and shows exactly where each belongs on a metal, textile, auto-component, pharma or FMCG floor.
The three housings, in plain terms
- Bullet — the long cylindrical camera with a visible sun-shroud. Named for its shell-like shape, it is instantly recognisable as a camera, which is why it works as a visible deterrent (Avigilon). Usually wall-mounted, pointing along a line of sight.
- Turret (also called "eyeball") — a ball-in-socket lens that twists and tilts inside a fixed base. Because the lens and the IR illuminators sit in separate housings with no glass dome in front, turrets largely avoid the night-time IR "halo" that plagues covered cameras (eufy).
- Dome — a lens under a tinted bubble. The bubble hides where the lens points and takes an IK10 vandal-resistant rating better than any other shape, but IR can reflect off the dome and cause glare once it clouds up (eufy).
IR glare: why it matters on a factory floor
Factories run 24/7, and much of the risk — a night-shift worker in a press zone, a forklift after dark — happens in low light. Here the housing choice is not cosmetic. A turret's separated IR and lens minimise reflection, keeping night images clear, while a dome's bubble can bounce infrared straight back into the sensor and wash out the frame (eufy comparison). Bullets also handle IR well and often pack more IR diodes for longer reach — good for a dark yard or a long aisle, but poor over an open work cell where you want a wide, glare-free view from above.
Deterrence vs discretion
A bullet's obvious silhouette tells people they are being watched, which is exactly what you want at a gate, a dispatch dock or a boundary wall. A turret is more discreet and less obviously a camera, so it draws fewer deliberate tampering attempts and is less likely to be grabbed — turrets and domes sit flush and are harder to reach than a protruding bullet (Mammoth Security). On a floor with a contract or migrant workforce, that discretion reduces the "camera got knocked" excuse.
Mounting and coverage
Bullets install most naturally on walls, aimed down a corridor or across a bay. Turrets and domes install most naturally on ceilings and overhangs, and the turret's ball-joint lets you fine-tune the angle after the base is fixed — no popping a bubble open (SCW). All three can technically be surface- or wall-mounted with a bracket, but fighting the natural mount wastes labour and leaves awkward angles. For an open production hall with a high roof, ceiling turrets give you top-down coverage of multiple cells; for a linear stores aisle or a perimeter, wall bullets follow the line.
Environmental and impact ratings (specify these)
Two international ratings decide whether a camera survives a real factory, and you should write them into your purchase order:
- IP66 (IEC 60529) — the enclosure is fully dust-tight and withstands powerful water jets. On a shop floor that means metal dust, textile lint, flour, or washdown near food/pharma lines won't kill it (IEC 60529, IEC webstore).
- IK10 (IEC 62262) — the housing resists a 20-joule impact, the top of the IK00–IK10 scale (IEC 62262, IEC webstore). Useful anywhere a pallet, forklift or a swung tool could hit the camera. IK10-rated vandal glass is most common on domes, which is why domes win in loading bays, back entrances and car parks.
For reach-height outdoor and floor positions, IP66 + IK10 is the standard industrial combination. Reserve the toughest IK10 domes for the spots that actually get knocked; don't pay for vandal glass on a camera 6 m up a roof truss.
Which goes where: the shop-floor comparison
| Factor | Bullet (wall) | Turret / "eyeball" (ceiling) | Dome (ceiling, vandal spots) |
|---|---|---|---|
| Best mount | Walls, gates, perimeter | Ceilings, overhangs, open halls | Low ceilings, exposed zones |
| Coverage style | Long, directional line of sight | Wide top-down over work cells | Wide, discreet, fixed |
| IR / night glare | Long-range IR; good outdoors | Lowest glare (separated IR) | Glare risk off the bubble |
| Deterrence | Highest (visible shape) | Moderate (discreet) | Low (hides lens direction) |
| Vandal / impact | Exposed, easy to grab | Flush, harder to reach | Best — IK10 vandal glass |
| Aim after install | Fixed at mounting | Re-aim freely (ball joint) | Re-aim inside bubble |
| Fits on the floor | Yard, dock, aisle, boundary | Production hall, assembly, QC | Loading bay, stores, back doors |
Zone-by-zone for an Indian plant
- Boundary wall, main gate, dispatch dock — bullet. You want visible deterrence and long IR down the approach.
- Open production hall, assembly, packing — ceiling turrets. Top-down, glare-free coverage of several work cells; re-aim as the line layout changes.
- Press shop / hazardous machinery (Factories Act §21 fencing, §22 work near machinery) — turret overhead on the danger zone so PPE and intrusion are visible from above.
- Loading bay, forklift lanes, back entrances — IK10 dome or bullet out of reach, where impact and tampering risk is highest.
- Pharma/food washdown lines — IP66/IP67 turret or dome that tolerates cleaning; verify the ingress rating on the datasheet.
Adequate lighting is not optional — the Factories Act, 1948 already requires sufficient and suitable lighting in every part of a factory where workers pass or work (Section 17) (full text, India Code). A camera can only analyse what it can see; fix dark corners before blaming the hardware.
Indicative India pricing (mid-2026)
Camera hardware in India is cheap relative to installation and analytics. As a rough planning band, mainstream 2 MP–4 MP IP bullet and turret cameras from Indian brands list roughly ₹1,000–₹3,500 each as of mid-2026, with entry models below ₹1,000 and higher-resolution or specialist units above — treat these as indicative, not quotes, and get written prices for your model and channel count (CP Plus listings, IndiaMART). Turret and bullet of the same sensor and brand usually cost within a few hundred rupees of each other, so choose by placement, not price. Budget separately for a PoE switch on a UPS, cabling, brackets, and — from 1 April 2026 — BIS/STQC-compliant hardware for any new purchase.
Getting placement right without a site survey
Choosing turret-vs-bullet per zone is really a sightline question: which camera sees the event — a worker's head for a helmet check, a forklift crossing a lane, a machine's state light — without glare or obstruction. Doing that across a whole plant by eye is slow and error-prone. This is the gap Mama closes: you record a short phone walkthrough of the floor, and it reads the space — zones, sightlines, hazards, mounting surfaces — then returns a floor plan plus a camera-placement plan that already says turret here, bullet there, dome in the bay, with the analytics use-case for each. You get the layout and the housing choice in a day, not after a paid survey.
FAQ
Is a turret camera better than a bullet for a factory? Neither is universally better — they suit different zones. Turrets excel on ceilings over open work areas because they resist IR glare and re-aim easily; bullets excel on walls, gates and perimeters where their long IR reach and visible shape deter intruders. A good plant uses both.
Why do turret cameras have less IR glare than domes? A turret keeps its IR illuminators and lens in separate housings with no glass dome in front, so infrared doesn't reflect back into the sensor. A dome's bubble can bounce IR into the lens, especially once the bubble is dusty or scratched, washing out night images (eufy).
What IP and IK rating should a shop-floor camera have? For most industrial positions, specify IP66 (dust-tight, resists water jets, per IEC 60529) and, where impact or tampering is likely, IK10 (20-joule impact resistance, per IEC 62262). Reserve IK10 vandal domes for loading bays and reachable spots; roof-height cameras rarely need them.
Are dome cameras still worth using? Yes, in the right place. Domes take the highest IK10 vandal glass and hide which way the lens points, making them ideal for loading bays, back entrances, car parks and low-clearance areas prone to tampering. Their weakness is IR glare and harder re-aiming, so they are a poor default for open production halls.
Do new factory cameras need BIS certification in India? CCTV cameras newly sold or installed in India from 1 April 2026 must meet the Essential Requirements notified by MeitY, validated through STQC and registered with BIS. Already-installed cameras can keep running; the rule applies to new sale/installation, so specify compliant turret and bullet models for any expansion.
