UKSUP SM663 Monitor Review
Our verdict
The UKSUP SM663 earns its 4.4-star average through reliable corded-electric operation and color night vision, though at $39.99 with 480p resolution it is priced a bit high relative to 1080p competitors. The 1,600-review base gives it a credible track record that many newer monitors in this range cannot match.

Overview
The UKSUP SM663 is a corded-electric baby monitor offering color night vision at $39.99. It runs from wall power, which eliminates battery management and guarantees continuous operation through overnight monitoring sessions. Color night vision is the feature most buyers at this price cite as the reason they chose it over basic infrared models, and the SM663 provides it reliably according to its established review record.
The 480p resolution is the main technical concession in the SM663's spec sheet. At a price point where some newer entrants now offer 1080p, the lower resolution stands out. In practice, 480p is adequate when the parent unit is close by and the camera sits near the crib, but it will look soft on larger screens or at distance. Parents who primarily glance at a compact parent-unit screen rather than streaming to a tablet will likely notice this less.
With 4.4 stars from 1,600 reviews, the SM663 has one of the more substantial review bases in its segment. That volume, combined with a 4.4-star average, is a strong signal of consistent performance across a wide range of households and usage patterns. Monthly purchase figures of 50 units indicate a mature listing that continues to sell steadily.
Pros
- 4.4 stars from 1,600 reviews is a well-established and credible satisfaction record
- Color night vision for a more natural nursery image in low light
- Corded-electric design ensures uninterrupted overnight power with no battery to manage
- Dedicated monitor keeps the feed off your home network and app ecosystem
Cons
- 480p resolution lags behind HD and 1080p monitors available at or below this price
- $39.99 is on the higher end for a 480p monitor when 1080p competitors undercut it
- Only 50 units bought last month suggests it may be losing ground to higher-res alternatives

Performance notes
Corded baby monitors avoid the signal drop-outs that can plague wireless units in busy radio environments such as apartments with many Wi-Fi networks. The SM663's color night vision mode is designed to show the nursery in a warmer, more natural palette versus green-tinted IR imagery. In well-reviewed monitors of this type, that color detail typically resolves blanket and clothing colors, helping caregivers quickly assess whether anything looks unusual without relying on interpretation of a monochrome frame.
What buyers say
A 4.4-star rating over 1,600 reviews is among the more reliable quality signals in the baby monitor category, where early-listing averages can be misleading. The large sample means the rating has been tested across many different nursery setups and usage durations. A small segment of buyers appear to note the resolution versus competitors, but the majority are satisfied with the overall performance for the use case.

Frequently asked questions
Is the UKSUP SM663 a Wi-Fi monitor or a dedicated parent-unit monitor?
Based on the specs, the SM663 is corded electric with no Wi-Fi listed, which is consistent with a dedicated parent-unit design. This means no app is required and the video feed stays within the local radio link between camera and parent unit.
Will 480p resolution be good enough to see my baby clearly at night?
For most parents using a compact dedicated parent unit within a few feet, 480p with color night vision is sufficient to confirm the baby's position and movement. However, if you plan to view the feed on a larger screen or keep the camera mounted far from the crib, a higher-resolution monitor would provide a noticeably clearer picture.
