Imou Rex 4MP Review: A Pan-Tilt Indoor Camera That Watches a Whole Room
The Imou Rex 4MP is an indoor camera with a motorized head that covers a room from a single spot: it records 1440p video, follows movement, sees in the dark with infrared and stores everything on a microSD card without a subscription. Buyers in Argentina praise how quickly it sets up with the Imou Life app, how sharp the image looks during the day and at night, and the magnetic base that lets them move it from the fridge to a shelf in seconds, and they use it to check on pets, children and elderly relatives. The trade-offs are concrete: the speaker sounds thin, the unit sold in Argentina ships without the power adapter, and the AI alerts for pets, vehicles and packages stay behind the Imou Protect plan. As a budget-friendly indoor camera, it is one of the most complete options in its tier.

- Pet, vehicle and package alerts, plus the longer cloud history, require the Imou Protect plan

- Indoor-only body with no water protection
Who is the Imou Rex 4MP for?
It is an indoor camera for someone who wants to cover a whole room with one unit. The head pans 355 degrees and tilts 90, the 4MP sensor records 1440p video through a 3.6 mm lens with a 92 degree horizontal field of view, and it switches to infrared night vision up to 10 metres when the lights go out. Setup runs through the Imou Life app on iOS and Android, it connects over 2.4 GHz Wi-Fi or its Ethernet port, and it detects motion and people, follows what moves and fires a warning light and siren when something is detected. Recordings go to a microSD card of up to 256 GB, to an NVR over ONVIF or to Imou Cloud. Buyers use it for pets, for a child's room, to keep an eye on an elderly relative and for small shops and offices.
What buyers love
The image is the compliment that repeats: buyers describe sharp 1440p video during the day, useful zoom to pick out details and night vision that stays clear in a dark room. Setup is the other constant, with the app guiding the Wi-Fi pairing in minutes and the magnetic base letting them park the camera on a fridge or a metal shelf and move it whenever they want. Several mention the two-way audio as the reason they bought it, since they talk to their children, their pets or the person they are caring for from the phone, and others highlight that the card recording keeps working with no subscription. The warning light and the siren are also mentioned as a real deterrent.
What to know before you buy
The speaker is the weak point buyers agree on: voices come out thin and distorted at normal volume, and one reports a faint hum from the microphone when sound capture is on in a silent room. The motion detection can fire on wind or on a pet, and person detection takes a moment to learn the room; the AI alerts that separate people, pets, vehicles and packages, like the longer cloud history, need the Imou Protect plan. The unit sold in Argentina ships with the USB cable only, so the buyer has to supply a good 5V/1.5A charger, and one reviewer says a weak charger makes the camera freeze. It only connects to 2.4 GHz Wi-Fi (no 5 GHz band), some buyers see short connection hiccups or a delay when streaming through Google Home, and the vertical travel stops at 90 degrees, so a few angles stay out of view. It is an indoor camera with no water protection, and the memory card is not in the box.
Is the Imou Rex 4MP worth it?
For an indoor camera in the budget tier, the Rex 4MP covers the essentials well: a full-room view with the motorized head, 1440p video, infrared night vision, human detection with a siren and a warning light, and local recording on a microSD card with no monthly fee. It is the right pick if you want to follow a pet or a person around a room and keep the footage local, and you can live with a modest speaker and a 2.4 GHz-only connection. If you need colour night vision, an outdoor body, pet and vehicle alerts without a plan or 5 GHz Wi-Fi, look at a model one step up.
Preguntas frecuentes
Does the Imou Rex 4MP need a subscription?
No. Live view, motion and human detection and recording to a microSD card of up to 256 GB work without paying anything, and the card keeps recording even without internet. Imou Protect is optional: it adds cloud history and AI alerts for people, pets, vehicles and packages, with a 30-day free trial for new users. The memory card is not included.
Does it work with Alexa, Google Home and Home Assistant?
Yes. The Imou Life account streams the camera to an Amazon Echo Show or a Google Nest Hub, and ONVIF support lets Home Assistant read the stream over the local network. It does not work with Apple Home, SmartThings or Matter.
How does it see at night?
It has infrared night vision up to 10 metres and the image is black and white. It has no colour night vision mode; the light on the base is a warning light that works as a deterrent.
Can it record without the cloud?
Yes. It records to a microSD card of up to 256 GB (the maker quotes around 4 days of footage on 64 GB, 8 on 128 GB and 16 on 256 GB), to an ONVIF NVR or to Imou Cloud. The card recording is local, so events keep being saved when the internet goes down.
Can I install it outdoors?
No. It is an indoor camera with no water or dust protection, so it belongs in a room, not on a patio or a balcony.
How is it powered?
It runs on DC 5V/1.5A from a USB cable and needs a permanent outlet, since it has no battery. The Argentine listing ships the USB cable only, so you need your own 5V/1.5A charger.
