Its core function is to provide clear 1080P high-definition video footage activated by a low-power Passive Infrared (PIR) human body sensor. This sensor detects movement within a 16-metre effective range, making it a practical choice for monitoring rooms, entryways, or valuable items. The camera's compact form factor, built from ABS plastic, allows for discreet placement on shelves, desks, or mounted on walls. Available models come with integrated storage, eliminating the need for external recording devices and offering a self-contained system for capturing footage directly.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"U21 wireless portable surveillance camera with compact ABS plastic housing.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/900\/2025-10-02\/original-image\/1619522060069.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe U21 camera combines several specific technical specifications to deliver its monitoring capability. Its construction focuses on reliable image capture, efficient motion detection, and a self-sufficient recording system.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe camera housing is constructed from ABS plastic, a material chosen for its rigidity and light weight, contributing to the product's overall portability of 0.03kg. This build houses the 1\/3-inch CMOS image sensor and a fixed 2.8mm lens, which together capture a wide field of view. The electronic shutter operates from 1\/3 second to 1\/100,000 second, allowing it to adapt to different lighting conditions, supported by a minimum illumination specification of 0.1 Lux.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe key measurable specification provided is the size of the image sensor, which is 1\/3 of an inch. This sensor size is common in compact security cameras. The camera's effective operational range is clearly defined: the PIR sensor can detect human body movement within a 16-metre distance, while the infrared lights have an irradiation distance of 8 metres for night vision. Its operational tolerance is specified by a working temperature range from -10 degrees Celsius to 60 degrees Celsius.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"U21 wireless portable surveillance camera with compact ABS plastic housing.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/900\/2025-10-02\/original-image\/1619522060070.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis camera is suited for indoor residential settings where a simple, wireless monitoring solution is preferred. Its design priorities inform where and how it can be most effectively used.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eWhile primarily for home use, the camera's specifications, such as the 48dB signal-to-noise ratio for clearer audio\/video separation and the defined temperature range, suggest it can handle consistent operation in various indoor environments. The availability of models with larger built-in memory (32GB or 64GB) supporting 10 or 20 days of recording makes it suitable for situations requiring extended evidence logging without daily maintenance, such as monitoring a holiday home or a small office outside business hours.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eFor typical household security, the camera's PIR sensor provides a battery-efficient way to record only when activity is detected, avoiding endless hours of empty footage. The 1080P resolution ensures that details like faces or licence plates are discernible if captured within range. Its USB power supply (5V) means it can be easily plugged into a standard wall adapter or power bank, offering flexible placement options away from fixed power outlets for monitoring nurseries, pet areas, or front doors.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"U21 wireless portable surveillance camera with compact ABS plastic housing.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/900\/2025-10-02\/original-image\/1619522060071.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe value of the U21 camera lies in its integration of key surveillance features into a single, portable unit, reducing setup complexity.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eThe product is designed as a dedicated surveillance tool. Its maintenance revolves around the storage cycle; once the built-in memory card is full, older footage will be overwritten by new recordings. Choosing a model with higher capacity (like the 64GB option) extends this cycle to approximately 20 days, reducing the frequency with which a user needs to review or archive footage. The ABS plastic housing is straightforward to wipe clean if dusty.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eThis camera presents a clear alternative to more complex CCTV systems. Its primary advantages are the inclusion of essential features—HD video, motion-activated recording via PIR, and built-in storage—in one device. The defined 16-metre detection range and 8-metre infrared distance provide concrete parameters for planning its placement. For users seeking a monitor for a specific room or asset without subscribing to cloud services or managing external hard drives, the U21's all-in-one design with selectable storage durations offers a specific, practical solution.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"U21 wireless portable surveillance camera with compact ABS plastic housing.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/900\/2025-10-02\/original-image\/1619522121177.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"U21 wireless portable surveillance camera with compact ABS plastic housing.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/900\/2025-10-02\/original-image\/2f1f5f34-eaba-4829-a73d-2b1e9101465a.webp\"\u003e\u003c\/div\u003e","brand":"test3334tak1fxioc","offers":[{"title":"Memory card 16G","offer_id":58528022593868,"sku":"CJJY110273505EV","price":12.0,"currency_code":"GBP","in_stock":true},{"title":"D","offer_id":58528022626636,"sku":"CJJY110273504DW","price":45.0,"currency_code":"GBP","in_stock":true},{"title":"C","offer_id":58528022659404,"sku":"CJJY110273503CX","price":40.0,"currency_code":"GBP","in_stock":true},{"title":"B","offer_id":58528022692172,"sku":"CJJY110273502BY","price":36.0,"currency_code":"GBP","in_stock":true},{"title":"A","offer_id":58528022724940,"sku":"CJJY110273501AZ","price":31.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/0000\/6988\/files\/1619522060069.webp?v=1787474068","url":"https:\/\/r0ugqn-kg.myshopify.com\/products\/u21-wireless-surveillance-camera-hd-usb-in-line-portable-monitor-with-1080p-resolution-16-metre-detection-range-and-low-power-pir-human-body-sensor-for-home-indoor-surveillance","provider":"NoriSelect.uk","version":"1.0","type":"link"}
