Night image depends on the illuminator, not on the sensor count
Two figures are printed on every box and only one of them changes what you see at night. Resolution sets how much detail exists in daylight; after dark the image is made by the illuminator — infrared LEDs that give a monochrome picture, or a white spotlight that keeps color and announces the camera. The other decision is where footage lands: a card in the camera, a drive on your network, or a cloud plan that may be required to keep anything at all. We compare stated IP rating, night vision method and range, resolution against usable detail, storage options, and whether a subscription is needed for recording.
1080p · 360° pan, 130° tilt · 30 m (98 ft) IR · microSD to 512 GB · IP65
An entry-level pan-and-tilt outdoor camera that records to its own card. TP-Link states 1080p, a 360° horizontal sweep and night vision to 30 m (98 ft), and the listing is unusually frank about what the model is not.
Best for: A first outdoor camera on a wall that already has a socket nearby, where 1080p is enough and the card matters more than the picture.

2K 3MP · 350° pan, 90° tilt · color night vision · siren · 2.4 GHz only
A 2K pan-and-tilt outdoor camera with a floodlight and a siren that trigger together on motion. Codnida states auto-tracking, a PIR sensor and custom detection zones, and the camera runs on mains power rather than a battery.
Best for: A driveway or side passage where the point is to make an approach visible and audible, not just recorded.
2K 3MP · 355° pan, 90° tilt · full-color night vision · 110 dB siren · IP66
Imou states a 3 MP sensor, four night-vision modes including full color, AI person and vehicle detection and a 110 dB siren, in a dual-antenna housing rated IP66. It also tracks what it detects, as the Codnida Q30S in this hub does.
Best for: A garden or driveway where false alarms from foliage and insects have already made a cheaper camera unusable.
2K 4MP · F1.6 Starlight · 360° pan · IP66 · Wi-Fi or Ethernet
A 2560 × 1440 sensor behind an F1.6 lens gives more color in low light before it turns on its spotlights, and it can be wired to Ethernet instead of trusting Wi-Fi.
Best for: An outdoor position where Wi-Fi is unreliable and a network cable can be run, or where color at night matters more than an unlit image.
5MP · dual-band 2.4/5 GHz · 30 m (98 ft) IR · microSD to 512 GB, NVR or FTP · IP66
A fixed 5 MP bullet camera rather than a pan-and-tilt, and the only camera in this hub that will record to an FTP server, as well as to a Reolink NVR or a card. Reolink states dual-band Wi-Fi, person, vehicle and animal detection, and 30 m (98 ft) night vision.
Best for: Someone who wants a fixed camera pointed at one thing permanently, recorded somewhere other than the camera itself.
Resolution decides what you can really make out at a distance. The Reolink RLC-510WA states 5 MP, the highest definition in this hub.
The angle of coverage decides the area watched per camera. The wider it is, the fewer cameras are needed — and the less detail you make out.
The ingress protection rating decides whether the camera survives direct exposure. An under-protected camera fails in its first winter.
It depends on where you live. In the United States, recording what is visible from a public street is generally lawful, but aiming at a neighbor's private spaces or recording audio can break state law. Most apps let you mask areas outside your property.
Rules vary by state. Signs are not required everywhere for video on your own property, but audio recording is tightly restricted in many states, and a visible sign is a common practice.
There is no general rule for private homes in the United States; keep footage as long as you need it and delete the rest, which also limits what a stolen account could expose.
Enough to identify a face at the intended distance, which depends as much on framing as on definition. A well-placed camera at modest definition beats a distant, very high-definition one.
It has two digits: the first for solid objects, the second for water. Under direct exposure, the second is decisive.
The LEDs give off a red glow visible close up. Models with invisible illumination cannot be seen; their stated range is not necessarily shorter.
Wired is stable and powers the camera through the same cable; Wi-Fi installs anywhere and depends on signal quality at the chosen spot.
High up, out of reach, under an overhang if possible, and framed on a point everyone has to pass. Not facing the rising or setting sun.
A well-framed camera at modest definition identifies better than a distant, very high-definition one. Keep the field on your own property, mask your neighbors' windows, and check your state's rules on audio recording.
A characteristic has to come from four devices in five to hold a column. Below that, we would be lining up empty cells.
