Night image depends on the illuminator, not on the sensor count · review
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.
The conclusion A low-priced pan-and-tilt camera with auto-tracking, bought for its person and vehicle detection. The dual antennas matter more than the specification sheet suggests.
The S21FEP is the camera to look at when a cheaper one has already been switched off because it notified too often. Imou states AI person and vehicle recognition specifically to filter the triggers caused by insects and moving branches, and those two causes account for most of the notifications that make an outdoor camera unbearable in summer.
A 3 MP sensor gives 2304 × 1296, which is enough to tell a delivery from a visitor at the length of a drive. The head sweeps 355° and tilts 90°, with auto-tracking, and Imou lists four night-vision modes — infrared for a monochrome image that does not announce the camera, and full color when the spotlight is on.
The dual antennas deserve more attention than they get. Imou states Wi-Fi coverage to 100 m (328 ft), and on an outbuilding or a gable end at the far corner of a plot, signal is the thing that decides whether a camera works at all.
Auto-tracking has the same flaw here as everywhere: after following something, the camera is left pointed at wherever that movement ended, which is usually the street. Set a home position over your weakest entry and the feature becomes an advantage rather than a risk.
IP66 is a rating Imou declares. It describes dust and jetting water, which in practice means the camera survives weather and does not survive being mounted where water can sit in the cable gland.
Someone replacing a first camera that cried wolf. The detection is the reason to buy it, the antennas are the reason it keeps working at the end of the garden, and the siren is a bonus rather than a purpose.

Imou states it is designed to filter triggers caused by insects and moving branches, which are the two commonest causes outdoors. It does not remove them: an insect on the lens at night is lit by the camera's own infrared and fills the frame, and no classifier deals with that. Placement out of the weather does more.
Light. Imou lists four night modes, and the color one relies on the spotlight or on ambient light — a camera cannot make color out of an infrared image. If you want color at night, the camera has to be visible at night.
It is loud enough to be unpleasant at close range and to wake a house. Decibel figures are quoted at one meter and fall away quickly, so it is a deterrent at the door and much less at the end of a garden.

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.
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.
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.
