Episode Details

Daniel needs one camera to inspect HVAC ducts, trace conduit for fishwire, and find roof leaks behind walls. This episode breaks down the real specs that separate a diagnostic tool from a blurry gray blob: why 1080p is the floor (and 4K is overkill), how cable length determines whether you get an answer or a guess, and why adjustable LED brightness is non-negotiable for seeing in dark cavities. We cover the Teslong TG100, Depstech DS300, and Klein Tools ET450 — what they do well and where they fall short for home diagnostics.
