Intrusion detection cameras can connect to a multi-channel network video recorder (NVR) over Ethernet, with Power over Ethernet (PoE) simplifying cabling and ONVIF support helping with device interoperability. They can also record to local microSD storage, send video and intrusion events to security platforms, and display live views through compatible smart home apps or control panels.

Choose a motorized varifocal lens, such as 2.7–13.5 mm, when coverage distances or viewing angles may change, with a dome for a discreet, low-profile installation or a bullet for more directional coverage. For compact areas with a consistent monitoring distance, a fixed 2.8 mm lens in a mini dome can provide a simple, unobtrusive option, while outdoor locations may benefit from an IP67-rated dome or bullet form factor.

When installing intrusion detection cameras outdoors, look for weather-resistant housings such as IP67, a mounting style suited to the location, Power over Ethernet (PoE), and local storage or network video recorder support. For challenging lighting, consider cameras with True Wide Dynamic Range (WDR), infrared night vision, or color-at-night imaging, along with analytics such as intrusion, line-crossing, and loitering detection.

Many intrusion detection cameras can record locally to a built-in or supported micro SD card, which allows standalone operation through a camera app. A network video recorder can be added when you need centralized recording, management, and storage for multiple cameras.
