Dimension comparison
Screen Size and Display Quality
The Blemil 5" Split-Screen Baby Monitor offers a noticeably larger viewing experience with its 5-inch display, compared to the 4.3-inch IPS screen of the Blemil Upgrade model. Both monitors feature split-screen capability, allowing you to view two cameras simultaneously. However, the Upgrade model specifically highlights its new-generation IPS technology, which is designed to provide wide viewing angles with vivid colours and exceptional clarity. The larger screen of the 5" model delivers a broader visual field and may be advantageous if you're monitoring from a distance, whilst the Upgrade's IPS panel excels in colour accuracy and brightness consistency. For parents who prioritise screen real estate and screen quality, the choice depends on whether you value the extra inches or the advanced IPS display technology.
Battery Life and Operating Modes
Battery longevity is a critical factor in baby monitors, and both models deliver impressive performance. The Blemil Upgrade provides 16 hours in video mode and 29 hours in ECO mode, whilst the 5" model offers 16 hours in video mode and 30 hours in Voice mode. The difference of one hour between their longest-life modes is marginal in practical terms. Both monitors employ energy-saving modes to extend usage—the Upgrade uses ECO mode, which pauses image transmission and reactivates based on sound detection, whilst the 5" model uses VOX mode with similar sound-activation functionality. For parents seeking maximum standby time, both represent excellent options, though the 5" model's 30-hour Voice mode rating provides a fractionally longer interval between charges.
Camera Specifications and Coverage
Both monitors are equipped with remote pan/tilt/zoom cameras, though their specifications differ slightly. The Blemil Upgrade features two remote cameras that rotate 310 degrees horizontally and 120 degrees vertically, with 2X zoom magnification. The 5" model's single camera (with the option to connect up to two additional cameras) rotates 320 degrees horizontally and 120 degrees vertically, also featuring 2X zoom. The Upgrade's standard dual-camera configuration provides automatic split-screen viewing of two nursery areas without additional purchases, whilst the 5" model's single-camera base setup allows for expandability but requires additional purchases for multi-view coverage. For comprehensive nursery monitoring without extra expenses, the Upgrade's dual-camera system is inherently more versatile.
Night Vision and Ambient Monitoring
Both models feature advanced infrared night vision with automatic activation in low-light conditions. The Blemil Upgrade emphasises "clear" auto infrared night vision enabling visibility in darkness, whilst the 5" model offers enhanced infrared night vision with upgraded infrared sensors following comprehensive refinement. Beyond night vision, the Upgrade model includes a room-temperature sensor, providing an additional layer of environmental awareness that the 5" model does not explicitly offer. This temperature-monitoring capability is particularly valuable for parents monitoring newborns and young infants, where maintaining appropriate ambient temperature is crucial for health and comfort. The 5" model prioritises infrared sensitivity, making it superior for pure night-vision clarity, but the Upgrade's temperature sensor adds practical utility.
Audio Communication and Features
Two-way talk functionality is standard on both monitors, enabling parents to communicate with their children remotely. The key distinction lies in supplementary audio features. The Blemil 5" model includes eight built-in calming lullabies to gently assist bedtime routines, a feature absent from the Upgrade model. Both monitors support adjustable volume controls, with the Upgrade specifically highlighting convenient direct button adjustment without menu navigation. The 5" model supports eight languages, expanding its appeal for multilingual households. For parents seeking bedtime assistance through soothing melodies, the 5" model's lullaby function provides an advantage. However, if you prioritise straightforward, intuitive controls and rapid volume adjustment, the Upgrade's simplified button-based operation may be more appealing.
Range and Connectivity
The Blemil 5" model explicitly advertises a transmission range of up to 1000 feet in open space, making it particularly suitable for larger homes or properties. The Upgrade model does not specify a maximum range in its feature list, though both units operate via closed digital transmission without requiring WiFi connectivity. The 5" model's extended range specification provides confidence for parents monitoring from greater distances within their homes. Both models maintain secure, WiFi-free operation, which eliminates internet security concerns but also restricts remote monitoring to within the stated range. For households with expansive layouts, the 5" model's publicised 1000-foot range offers reassurance; for standard homes, both should prove adequate.
Price and Value Proposition
The Blemil Upgrade retails at £89.99, positioned as the premium option, whilst the Blemil 5" model is priced at £47.99, representing approximately 47% savings. The Upgrade ranks first in its category bestseller list, whilst the 5" model holds fourth position. The price differential reflects the Upgrade's dual-camera system, IPS display technology, and temperature monitoring. The 5" model delivers excellent value through its larger screen, extended range specification, and lullaby features at a lower cost. For budget-conscious parents, the 5" model provides substantial functionality at nearly half the price. For those prioritising dual-camera coverage and temperature monitoring, the Upgrade justifies its premium despite its smaller screen.
Which should you buy?
Choose the Blemil 5" Split-Screen Baby Monitor with 30-Hour Battery if you prioritise value, want a larger display, appreciate lullaby features, and monitor from greater distances within your home. Its £47.99 price point, 5-inch screen, extended 1000-foot range, and soothing music functionality make it ideal for budget-conscious parents seeking comprehensive features. Select the Blemil Upgrade Baby Monitor with 29-Hour Battery if you require dual-camera monitoring from the outset, value IPS display clarity, and need room-temperature monitoring for newborn safety. Although pricier at £89.99, its two integrated cameras eliminate expansion costs and its premium display technology ensures exceptional visual clarity, making it worthwhile for parents wanting comprehensive, ready-to-use dual-nursery coverage without future purchases.
