Philips Avent SCD510/00 through SCD730/86: compare six DECT audio references
The Philips Avent SCD510/00, SCD520/00, SCD560/10, SCD570/10, SCD720/86 and SCD730/86 are six discontinued U.S. DECT audio owner references, not current buying choices. Each reviewed setup sends a single room’s sound to a Parent Unit without a camera picture or documented phone-viewing plan. The SCD510/00 is the simplest receiver and has no documented temperature readout; the other five have a Parent Unit display and exact-model temperature function. The SCD730/86 adds a starry projector, while the SCD720/86 has an optional Eco Max mode with a range-alert compromise. Use exact model labels when identifying a set.
Shared routine: one receiver, one sound feed
Each reviewed manual describes a local baby-unit/parent-unit sound link, adjustable sensitivity and volume, and manufacturer-stated range maxima of up to 330 metres (1,000 feet) outdoors and 50 metres (150 feet) indoors. These are not measured results inside a particular building. All six are audio-only, but the Parent Units differ: the SCD510/00 has indicators rather than an LCD, and its exact controls do not establish a temperature readout; the SCD520/00, SCD560/10, SCD570/10, SCD720/86 and SCD730/86 manuals describe local temperature displays. Check which functions are documented for the exact model rather than extending a family feature across suffixes.
None has a documented app or internet phone path. If you need to see the room, compare a video model; if away-from-home access is essential, look for a verified connected plan. Keep the relevant manual with the units, test the link in the intended rooms and do not infer two-room audio or component compatibility from the brand name.
The SCD510/00 is the simpler audio reference
The exact SCD510/00 page and its manual describe a local DECT sound feed with adjustable sensitivity, sound-level LEDs, talk-back, a belt clip and a Baby Unit nightlight. Its Parent Unit uses status lights rather than an LCD or camera view. A general manual paragraph mentions a temperature sensor, but Philips does not describe an SCD510 temperature display or alert control in the exact product features or operating instructions; keep that capability unknown. The manual claims up to 1,000 feet outdoors and 150 feet indoors, and up to 24 hours cordless after the specified battery charging cycles. Philips marks the exact model no longer available, so keep it out of current buying matches. Read the SCD510/00 owner reference.
Where the SCD520/00 changes the choice
The exact SCD520/00 product page and manual claim up to 24 hours of cordless Parent Unit use after charging; its instructions say normal charging takes about eight hours, with at least ten hours for first use or after long disuse. The exact SCD560/10 and SCD570/10 manuals instead state up to 18 hours after a full ten-hour charge. These are conditional manufacturer figures, not estimates for an old battery. The SCD520 manual names its SCD520 NiMH pack; for any used set, inspect the receiver, pack and charging base rather than assuming they are present or healthy.
The SCD520 still has a configurable temperature alert, talk-back, sound-level lights and a muted-volume alert when noise reaches the fourth light. That threshold is not a cry classifier. Its manual also identifies five lullabies, but Philips' exact U.S. page says remote lullaby control is unavailable in the U.S. and remote nightlight control is unavailable in the U.S.; the Baby Unit's own controls matter. Its LCD shows temperature and status rather than video, and its link is local DECT without Wi-Fi. In that sense it shares the basic room-audio task with the /10 models but is not an interchangeable or merely relabeled variant.
Choose between simpler lights and vibration alerts
The SCD560/10 has three sound-level LEDs and no charging station or vibration alert. The SCD570/10 has five LEDs, a parent-unit charging station and a night-dim mode that lowers the lights/display and alert volume. Most importantly, the SCD570 manual offers vibration-only or sound-and-vibration alerts. Its named cry alert vibrates when the room sound reaches the fourth LED threshold and repeats until the sound drops or the alert is switched off. This is a loudness-threshold prompt—not intelligent cry classification, a guarantee that every cry will trigger it or a medical alarm. The SCD560 is the more basic receiver; the SCD570 gives an owner more tactile and visual feedback.
SCD720/86 and SCD730/86: a projector and mixed Eco Max documentation
The exact Philips comparison shows that SCD720/86 and SCD730/86 share the one-room DECT audio role, Parent Unit temperature/status display, five sound-level lights, talk-back, nightlight and similar published range and battery maxima. It lists the starry night projector on the SCD730/86 and not the SCD720/86. The SCD730 manual describes six colored patterns and timers from five to twenty minutes or continuous operation; it adds a comfort feature, not a camera picture.
Both the current and prior English U.S. SCD720/86 manuals document Eco Max: Baby Unit radio transmission stops while the room is quiet and resumes when it detects sound. Philips warns that this brings delayed feedback and no out-of-range alert while the Baby Unit is silent; the mode is unavailable at highest sensitivity. The SCD730/86 has a documentation conflict: an earlier SCD73x English manual linked from its exact /86 route names SCD730 and includes Eco Max, while the later SCD730-only manual linked on the same route documents Smart Eco but omits Eco Max. Because Philips has not reconciled these exact-route revisions, the SCD730 Eco Max field is unknown rather than yes or no. A must-have Eco Max query can confirm the SCD720 and must not treat SCD730's earlier family manual alone as definitive for every /86 unit. The projector remains the verified SCD730 difference; owners should read the manual for their actual set before enabling a mode.
Battery and ECO details need exact model handling
Philips lists up to 18 hours of cordless parent-unit use after a full ten-hour charge for the SCD560 and SCD570. The claim is not a test of an aging used battery. The SCD570's exact product image and specification list a charging station; the SCD560 has no station, although its receiver still charges. Both manuals say the baby unit can use four AA alkaline cells as backup during a power failure and warn not to use rechargeable cells in the baby unit; the cells are not included. Philips does not give a backup-duration estimate in the reviewed manuals.
There is also a package-content conflict worth checking before accepting a used set: both manuals describe two rechargeable Parent Unit batteries as supplied, while Philips' exact U.S. comparison table marks the Batteries accessory row “No” for both models. The device instructions and actual package contents are different questions; verify the specific receiver and kit rather than relying on the picture or a generic family description.
Do not mistake a generic specification line for a U.S. feature. Philips’ exact SCD560/10 product page states Smart ECO is unavailable in the United States and Canada; the broad spec sheet’s generic Eco-mode entry does not override that qualification. The same North American limitation appears in SCD570’s exact U.S. product material. If that feature matters, neither of those exact U.S. versions should be selected on a generic spec-sheet assumption. The SCD720's separate Eco Max mode and the SCD730's Smart Eco listing are documented for those different models.
Owner reference, not compatibility guidance
Read the SCD510/00 and SCD520/00 owner references for the simpler receiver and the 24-hour battery claim; the SCD560/10 and SCD570/10 reviews explain their differing lights and charging/alert options. The SCD720/86 review covers Eco Max, and the SCD730/86 review covers the projector. Check both labels before replacing or pairing used equipment: a shared brand or similar cradle is not proof that a Parent Unit and Baby Unit interoperate. Philips instructs caregivers to keep the Baby Unit outside the bed/playpen and its cord at least one metre from the child. These discontinued monitors support adult supervision; none is a medical device or a substitute for safe-sleep practice.
