Shopping for a security camera system can feel like learning a new language. DVR. NVR. PoE. Lux. Codec. WDR. The list never ends.

I've installed dozens of OHWOAI security camera systems, and I still remember how confused I was when I first started. Every spec sheet seemed designed to overwhelm me.

This glossary covers the terms that actually matter. Bookmark it. Refer back to it. And stop feeling like you need an engineering degree to protect your home.

A

Analog Camera: Traditional security cameras that send video signals over coaxial cables to a DVR. Older technology. OHWOAI focuses on modern digital systems.

Aperture: The opening in a camera lens that controls how much light enters. Wider aperture = better low-light performance.

Artifacts: Visual distortions in video caused by compression. Looks like blocky pixels or smearing.

B

Backlight Compensation (BLC): Feature that brightens dark areas when there's strong light behind the subject. Helps when someone stands in front of a bright window.

Bandwidth: The amount of data your network can transmit per second. Security cameras consume bandwidth, especially at higher resolutions.

Battery-Powered Camera: Wireless camera that runs on rechargeable batteries. OHWOAI offers battery options for renters and hard-to-wire spots.

BNC Connector: The twist-lock connector used on analog cameras. Not used on OHWOAI's modern PoE systems.

Bullet Camera: Long, cylindrical camera shaped like a bullet. Designed for long-range, focused viewing. OHWOAI bullet cameras are popular for driveways.

Bitrate: The amount of video data your camera sends per second. Higher bitrate = better quality but more storage.

C

Cat5 / Cat5e / Cat6: Types of Ethernet cables. Cat6 is recommended for OHWOAI 4K PoE systems for best performance.

CCTV (Closed Circuit Television): Old-school term for security camera systems. OHWOAI systems are modern IP-based, not traditional CCTV.

Codec (Coder-Decoder): Software that compresses video to save space. H.265 is roughly twice as efficient as H.264.

Color Night Vision: Night vision that captures color footage in low light. Requires some ambient light.

Compression: The process of reducing video file sizes. Good compression balances quality and storage.

Continuous Recording: Recording mode where cameras capture video 24/7. Uses more storage but ensures nothing is missed.

D

Digital Zoom: Cropping and enlarging an image digitally. Degrades quality. OHWOAI cameras use digital zoom for app viewing.

DNR (Digital Noise Reduction): Feature that reduces "snow" or grain in video, especially at night.

Dome Camera: Camera housed inside a dome-shaped cover. Discreet and vandal-resistant. OHWOAI dome cameras are popular for indoor and covered outdoor areas.

Doorbell Camera: Security camera integrated into a doorbell. Lets you see and speak to visitors remotely.

Drip Loop: Installing cables so they drop down before entering the camera. Water drips off instead of running into the connection.

DVR (Digital Video Recorder): Recorder for analog cameras. Older technology. OHWOAI uses modern NVR systems instead.

E

End-to-End Encryption: Security feature that encrypts video from camera to viewing device. Prevents unauthorized access.

Ethernet Cable: Network cable used for PoE cameras. Carries both power and video.

Event-Based Recording: Recording triggered by motion or AI detection rather than continuously. Saves storage space.

Exposure: How much light the camera sensor captures. Affects brightness and detail.

F

Facial Recognition: AI feature that identifies specific individuals. Requires a database of known faces.

False Alert: Notification triggered by harmless movement. OHWOAI's AI detection dramatically reduces false alerts.

Field of View (FOV): How wide an area a camera can see. Measured in degrees. 90° is standard. 110°-130° is wide-angle.

Firmware: Internal software that runs your camera. OHWOAI releases regular updates to fix bugs and improve performance.

Fixed Lens: Camera lens with a fixed field of view. Cannot zoom. Most home cameras use fixed lenses.

FPS (Frames Per Second): How many images the camera captures per second. 15-20 FPS is adequate. 30 FPS is smoother.

G

Gain: Amplification of video signal in low light. Higher gain = brighter image but more noise.

Ground Loop: Electrical issue causing rolling bars in video. Fix with ground loop isolator.

Guest Network: Separate WiFi network for smart devices. Keeps your main network more secure.

H

H.264: Common video compression standard. Efficient and widely compatible.

H.265 (HEVC): Newer compression standard that's roughly twice as efficient as H.264. OHWOAI 4K cameras use H.265.

HLC (Highlight Compensation): Feature that reduces bright spots like headlights.

Hybrid System: Combines local storage with cloud backup for maximum protection.

I

Image Sensor: Component that captures light and converts it to video. Larger sensors perform better in low light.

Infrared (IR): Invisible light used for night vision. OHWOAI cameras use adjustable IR LEDs for optimal night vision.

IP Camera (Internet Protocol Camera): Digital camera that sends video over a network. OHWOAI cameras are IP cameras.

IP Rating (Ingress Protection Rating): Measures weather resistance. IP66 means dust-tight and protected against powerful water jets. OHWOAI outdoor cameras are IP66 rated.

IR Cut Filter: Mechanical filter that slides over the sensor during the day (for normal colors) and away at night (for IR).

IR Range: How far infrared LEDs illuminate at night. OHWOAI cameras offer realistic 80-100 foot ranges.

K

Key Frame: A complete video frame that other frames reference. More key frames = better quality but larger files.

L

Lens: The glass element that focuses light onto the sensor. Quality matters more than megapixels.

License Plate Recognition (LPR): Specialized feature that captures and reads license plates. OHWOAI offers LPR on select models.

Local Storage: Storing video on a hard drive in your NVR. No monthly fees. Your footage stays on your property. OHWOAI systems prioritize local storage.

Loop Recording: Automatically overwrites oldest footage when storage is full. Ensures continuous recording.

Lux: Measurement of light sensitivity. Lower lux = better low-light performance.

M

Magnetic Mount: Adhesive mount that doesn't require drilling. Popular for renters using OHWOAI wireless cameras.

Mesh WiFi: WiFi system with multiple access points for seamless coverage. Helps wireless cameras in large homes.

MicroSD Card: Small memory card for local storage in wireless cameras. OHWOAI cameras support high-capacity SD cards.
