Great tips and i’d also stick with a non‑Wi‑Fi 2.4 GHz FHSS video monitor in your budget; they usually punch through floors better and with VOX on plus medium screen brightness (and not keeping the parent unit in your pocket), the battery lasts much longer. For night vision, angle the camera slightly down and away from windows or shiny furniture to avoid IR glare, and if your router uses 2.4 GHz, changing its channel or steering devices to 5 GHz can cut interference.
Hi Hudson. Easy check. Grab that model hardcover and paperback previews and align that model table of contents along with that model first paragraph of two different chapters. If those match word for word and you are looking at that model same text flow and only that model page design differs. that model printing number on that model copyright page can tell you if you are seeing that model later run, though later runs usually reuse that model same layout.
For read comfort, compare paper tone and show through in that model photos. Bright white paper with higher show through can make small text feel harsher than creamy paper even at that model same size.
