Turret vs. Dome IP Cameras: Vandalism Resistance, Glare, & Night Vision
Turrets and domes can use the same sensor, the same lens, and the same firmware. They still behave very differently at 2 a.m. under infrared, or after a year of dust and spider webs, or when someone hits one with a broom handle.
This guide skips the brochure talk. It covers what decides the choice on real commercial jobs, so you can pick the form factor for each spot on the drawing before the bid goes out. All NorthStar IP cameras are NDAA compliant, whichever housing you pick.
The short answer
- Turret (eyeball): pick it for most outdoor walls, eaves, and parking areas where the camera is out of reach. It gives the cleanest night picture and the fewest service calls.
- Vandal dome: pick it where people can reach or hit the camera, where the customer wants the camera to look less obvious, or where you don't want people to see which way the camera points.
The rest of this guide explains why.
How they are built
A turret puts the lens in a ball that sits in a socket. The infrared LEDs sit around the lens, behind their own flat window, and a divider keeps the IR light away from the lens. Nothing curved sits between the lens and the scene.
A dome puts the lens and IR LEDs under one curved clear cover, often polycarbonate. The cover protects everything inside, but the infrared light and the picture both pass through that same cover.
That one difference causes most of the trade-offs below.
Night vision and IR glare
This is where turrets win most clearly.
On a dome, a small amount of infrared light reflects off the inside of the cover back toward the lens. A rubber IR shield ring helps, but it only works if it sits flat against the cover. If it gets pushed out of place during install, or the cover goes back on slightly crooked, you get a hazy, washed-out night picture or a bright ring at the edge.
It gets worse over time. Dust, pollen, water spots, spider webs, and small scratches on the outside of the cover catch the IR light and glow. A dome that looked great at handover can look foggy after one season, especially near parking lots, gravel, or building lights.
A turret avoids most of this because the IR light never passes through the same window as the picture. Dirt on the front glass still matters, but it doesn't light up the same way.
Common night problems and fixes:
| Problem | Most common cause | Fix |
|---|---|---|
| Foggy or hazy night image (dome) | IR shield ring not seated, or dirty cover | Reseat the ring, clean the cover, check for scratches |
| Bright halo at frame edge (dome) | Lens tilted close to the cover edge | Re-aim so the lens looks through the middle of the cover |
| Glowing spots that move with wind | Spider webs near the IR LEDs | Clean, and consider a turret at that spot |
| Bright wall, dark yard | IR bouncing off a nearby wall or soffit | Lower IR power, or move the camera off the wall edge |
| Washed-out nearby faces | Too much IR at close distance | Use smart IR, or lower IR intensity |
Spider webs are a real issue for both styles, since bugs are drawn to IR light. They tend to hurt domes more because the whole cover lights up.
Vandal resistance
This is where domes win.
Impact ratings use the IK scale. IK10 is the top common rating and means the housing survives a 20-joule hit, about a 5 kg weight dropped from 40 cm. Always check the actual rating on the product sheet. Never assume it from the camera style.
Why domes handle hits better:
- A round, smooth cover gives a hammer or rock nothing to catch on. Hits tend to slide off.
- There is no ball to knock out of aim. A turret can survive a hit and still end up pointing at the ground.
- Domes are harder to grab, cover with a bag, or spray-paint straight into the lens.
- People can't easily tell which way a dome is pointing.
Where a turret is weaker:
- The ball can be pushed or twisted out of aim if the camera is within reach.
- It's easy to see which way it points, so it's easy to avoid.
Rule of thumb: if someone can reach the camera standing on the ground or a short ladder, use an IK10 vandal dome. If it's mounted high on a wall or eave, a turret is usually fine.
Weather and moisture
Both styles come in IP66 and IP67 versions, so both can work outdoors. The differences are about upkeep:
- Domes rely on a seal around the cover. If the cover is opened for aiming and not closed evenly, moisture can get in and fog the inside. Tighten cover screws evenly, and replace any desiccant pack if the camera came with one.
- Turrets usually stay sealed after aiming because you aim them from the outside. That means fewer chances to break the seal on site.
- Under an eave, both stay cleaner. Fully exposed to rain and sun, domes need cleaning more often to keep night images sharp.
Install and aiming
| Task | Turret | Vandal dome |
|---|---|---|
| Aiming | Turn the ball by hand from outside | Usually remove the cover, aim, refit |
| Re-aim after handover | Quick | Slower, risk of fogging or ring issues |
| Wall mounting | Natural fit | Often needs a bracket |
| Ceiling mounting | Works | Natural fit, low profile |
| Cleaning | Small flat glass | Whole cover, scratches easily |
On a large job, those minutes per camera add up. For crews doing 30 or more outdoor cameras, turrets usually save real labor.
Where to use each
| Location | Best fit | Why |
|---|---|---|
| Outside walls, high | Turret | Best night picture, easy aiming |
| Under eaves and soffits | Turret | Low glare, stays clean |
| Parking lots on poles | Turret or bullet | Clear night picture at distance |
| Entrances within reach | Vandal dome | Survives hits, harder to tamper with |
| Stairwells and halls | Vandal dome | Low profile, tamper resistant |
| Elevators | Vandal dome | Compact, ceiling mount |
| Stores and lobbies | Dome | Looks less obvious |
| Schools, transit, public housing | Vandal dome (IK10) | Expected abuse |
| Dusty sites or near bright lights | Turret | Less IR glow from dirt |
Field checklist before the bid
- Mark each camera location as within reach or out of reach.
- Note whether the spot is covered or fully exposed to weather.
- Note any close walls, soffits, or bright lights that could cause IR glare.
- Use IK10 domes for every location within reach.
- Use turrets for high outdoor spots unless the customer asks for a less obvious look.
- Check power draw on the spec sheet so your PoE switch has headroom for IR at night.
- Size recording with the NVR storage sizing guide, since night scenes use more storage.
- Do a night walk-through after install and fix any glare before handover.

Frequently asked questions
Is a turret or dome camera better for night vision?
Turrets usually give a cleaner night picture. Their infrared LEDs sit behind a separate window from the lens, so IR light does not reflect back into the image. On a dome, IR can bounce off the inside of the cover, and dirt, scratches, or spider webs on the cover glow under IR.
Which is more vandal resistant, a turret or a dome?
A vandal dome with an IK10 rating is the better choice anywhere people can reach the camera. Its smooth round cover deflects hits, it has no ball that can be knocked out of aim, and it hides which way the camera points.
Why does my dome camera look foggy at night?
The most common causes are an IR shield ring that is not seated flat against the cover, a dirty or scratched cover, or the lens aimed close to the cover's edge. Reseat the ring, clean the cover, and re-aim so the lens looks through the middle of the dome.
What does IK10 mean on a security camera?
IK10 is an impact rating. It means the housing withstands a 20 joule hit, roughly a 5 kg weight dropped from 40 cm. Always confirm the rating on the specific camera's spec sheet.
Should I use turret cameras outdoors?
For most outdoor walls, eaves, and soffits mounted out of reach, yes. Turrets are quick to aim, stay sealed after aiming, and avoid most IR glare. For outdoor spots within reach, use an IK10 vandal dome instead.
