Lorex security cameras come with smart features that help you see clearly no matter how tricky the lighting gets. Whether you're dealing with bright windows, nighttime glare, or shifting daylight, exposure modes like WDR, BLC, HLC, and Auto-Sensing help your camera adjust on the fly for the best possible image.
Watch this quick video to see how these settings work in real-life situations:
What Are Exposure Modes?
Exposure modes control how your camera handles light and shadow. They’re especially helpful in places where lighting can be uneven, overly bright, or constantly changing.
These modes are available on popular Lorex models like:
- A4 Series
- N4 Lite Series
- LNZ43P4A
- LNZ45P25
- LNZ85P25
Let’s break down what each mode does and when to use it.
Wide Dynamic Range (WDR)
What it does:
Balances super bright and super dark areas in the same frame so nothing gets lost.
Perfect for:
- Storefronts with big glass windows
- Garages or warehouses with sunlight pouring in
- Outdoor areas with shade and direct sun
What you’ll see:
- WDR ON: Clear details in both light and shadow
- WDR OFF: Washed-out bright spots or murky shadows
Why it matters:
You won’t miss important details just because of bad lighting.
Backlight Compensation (BLC)
What it does:
Brightens up people or objects that look too dark because they’re in front of a light source.
Perfect for:
- Someone standing in front of a window
- Hallways with a bright doorway in the background
What you’ll see:
- BLC ON: Foreground is nicely lit, faces are visible
- BLC OFF: People appear in silhouette
Why it matters:
Keeps people and objects visible, even against a bright background.
Highlight Compensation (HLC)
What it does:
Tones down really bright lights like headlights or spotlights that can overpower the image.
Perfect for:
- Driveways or streets at night
- Parking lots with headlights or floodlights
What you’ll see:
- HLC ON: Headlights don’t drown out everything else
- HLC OFF: Blinding lights block out useful details
Why it matters:
Helps your camera see better at night by cutting through glare.
Auto-Sensing
What it does:
Automatically adjusts brightness and color based on how lighting changes throughout the day.
Perfect for:
- Open offices or homes with lots of windows
- Areas that go from bright to dim, like a sunroom
What you’ll see:
- Auto-Sensing ON: Smooth, balanced lighting all day
- Auto-Sensing OFF: Washed-out or dull images as lighting shifts
Why it matters:
Hands-free setting that keeps your footage looking great around the clock.
