A bullet camera points an elongated housing toward a defined scene, with lens selection, mounting stability, exposure, and night testing shaping results.
03 / Definition
A dome camera uses a rounded, low-profile housing whose optical clarity, mounting orientation, exposure rating, and night behavior require deliberate planning.
04 / Definition
A doorbell camera combines a visitor button, video, audio, alerts, and optional recording, requiring careful view, power, network, and privacy planning.
05 / Definition
A surveillance DVR records camera signals commonly delivered over coax, with format compatibility, cable condition, storage, security, and serviceability driving design.
06 / Definition
An IP camera sends digital video and events over a network, making compatibility, power, bandwidth, credentials, firmware, and storage essential planning factors.
07 / Definition
Motion detection recognizes configured changes and can trigger recording or alerts, but scene conditions, thresholds, zones, and response rules determine usefulness.
08 / Definition
Camera night vision uses sensor sensitivity, exposure, infrared or visible illumination to form low-light images, with motion and reflections limiting performance.
09 / Definition
An NVR records and indexes network-camera streams while managing storage, playback, events, users, health, compatibility, and often remote access.

A privacy mask hides a configured image region, but its protection depends on where it is applied and whether every stream, recording, and export…
11 / Definition
Remote viewing provides authorized off-site access to surveillance video through a supported connection, with cybersecurity, bandwidth, accounts, and outages affecting availability.
12 / Definition
A security camera observes a defined scene, but useful results depend on lens choice, distance, lighting, mounting, recording, and system compatibility.
13 / Definition
Video analytics interprets images or metadata to detect configured events, with camera geometry, software, compatibility, privacy, and testing shaping reliability.
14 / Definition
A video intercom routes an entry camera and two-way audio to selected recipients, with separate planning for call behavior, network availability, and release authority.
15 / Definition
Video surveillance coordinates cameras, transport, storage, viewing, permissions, and retention around clearly defined observation and review goals.
