Security & Surveillance Equipment

Decide between wired (reliable power/network) and wireless (easier installation), pick resolution (1080p or higher for clearer detail), consider night vision and weatherproof ratings for outdoor use, and choose between continuous recording (DVR/NVR) or event-based recording depending on storage needs

Options include local storage (microSD, DVR/NVR) and cloud subscriptions; check supported storage capacity and whether the system records continuously or only on motion, and confirm retention time and export/import methods for evidence preservation

Compare resolution (720p, 1080p, 4K), sensor type, bitrate, and lens specifications; for low light, look for IR/night vision range, image sensors with good low-light sensitivity, and features like WDR (wide dynamic range) for high-contrast scenes

Verify whether cameras use Wi‑Fi, Ethernet, or PoE (Power over Ethernet); ensure your network bandwidth and router can handle multiple streams and that you have appropriate power sources or PoE switches/injectors for wired devices

Check protocols (ONVIF, RTSP), video formats, port types, and mounting options to make sure cameras, recorders, and power units from different brands will interoperate; confirm firmware update support and documentation

Regularly clean lenses, check mounts and weather seals, update firmware for security patches, verify recording and alerts periodically, and replace batteries in wireless sensors per manufacturer-recommended intervals

Entry-level cameras and sensors are available under $50, mid-range systems commonly fall between $100–$300 per device or kit, and professional-grade recorders or multi-camera systems can cost more; factor in potential subscription and installation costs
