Does the E340 need a subscription?

No. It records 24/7 to a microSD card or a HomeBase S380 without a cloud plan. Cloud storage is optional.

Do I need the HomeBase S380?

Only for face detection and encrypted recordings. The camera works standalone with a microSD card.

It is wired and wall-mounted, so it needs an outdoor junction box with constant power. Plan on an electrician if you do not have one.

What is the difference between the two lenses?

The wide lens shoots 3K for the overall scene; the telephoto shoots 2K and zooms up to 8x hybrid for details up to about 50 ft away.

Does it work with Alexa and Google?

Yes. It supports both Google Assistant and Alexa for live view and basic control.

Floodlight cameras tend to drop around Black Friday and Prime Day. At $80 at eBay as of November 7, 2026, it is already near the low end for a dual-lens model.

What reviewers say

Owners like the dual-lens setup and the bright floodlight, and many value 24/7 local recording without a monthly fee. Complaints center on the wired install and on features locked behind the HomeBase.

What people mention

Video qualityPraisedOwners call the 3K wide image sharp and the 2K telephoto useful for reading plates and faces at distance.
FloodlightPraisedThe 2,000-lumen light is bright enough to light a driveway, and brightness is adjustable in the app.
InstallationCriticisedThe wired mount is the main gripe; buyers say it needs an existing box or an electrician.
HomeBase lock-inCriticisedFace detection and encrypted storage require the HomeBase S380, which is not included.
Local storagePraisedMicroSD and HomeBase recording give 24/7 footage without a cloud plan.
Motion alertsMixedDetection works but triggers often; owners tune zones and sensitivity to cut false alerts.
