    Great working camera here.

    A STRAIGHT FORWARD 2 YEAR REVIEW HERE.This camera has been operating great since installation. The options are flexible as to personal settings. You just have to find your own “SWEET SPOT” settings, when testing it out as to the location you install it, which can potentially take patience. Once you do it works fine. No issues with connectivity so far. I recommend that every once in a while you reset the home base for a fresh start. Don’t mistake that with the remove device option, just the RESET. It seems to keep the connection strong. The picture quality is awesome and the 2000 LMS is a reall

    Great features and NO subscription required.

    I've only had the floodlight camera E340 installed for 2 weeks. So far it seems to be very capable but some features are not as user-friendly as my old Ring system; for instance, reviewing recorded events was easier on the Ring. One of the primary reasons I picked this system was its internal storage (sometimes called local storage). After some difficulty getting the microSD card to work, it does appear to be working now. The product details on Amazon lead me to believe the unit was capable of using 6GHz wifi—that is not the case; "wifi 6 capable" does not mean 6GHz—still not sure what that me

    Excellent camera, just make sure to get the home base too!

    Wow, I am impressed so far! This video of the cute feline was taken while I was fast asleep, the camera itself is tracking the cat. I blacked out the areas for privacy. If you notice the cat doesn’t even hear the camera moving, it’s extremely quiet. I have watched it track me and I also do not hear anything and you can also hardly tell it’s moving unless you know about it and are staring it it!! You can also turn the AI tracking completely off and just have it on a fixed area if you want.I did get the Eufy home base S380 unit with a separate (not included) Samsung 1tb SSD (exact model in my re

    Eufy Floodlight Cam E340: A Hit or Miss?

    I have been a fan of the eufy product for a while. I have all the cameras, indoor and out. Lately I have started to lose a great deal of confidence in their products. I have two of the floodlight cams, I initially bought it because of it's 360-degree capabilities with tracking.I originally bought Floodlight Cam 2 Pro in 2021 and it worked great for a year and then the connectivity issues started. You will have to go read my recent follow-up review of that one. In short, it's a lemon!For this one, it works great as long as you don't put in a Micro SD card. This camera will fry every card, then

    DON'T BUY - INCREDIBLY FRUSTRATING!

    First, let me say that I WAS a fan of Eufy and have bought 20-24 of their security products at 3 locations. I have called Tech Support prior several times and they were great. In fact, I would brag about their Tech SupportI just retired and was setting up one of my son's homes with multiple Eufy security products. Needed to call Tech Support on the new Door Bell Cam and to my surprise - YOU ONLY GET A BOT! The bot tells you - you WILL NEVER SPEAK TO A HUMAN!INCREDIBY FRUSTRATING! Bot is condescending in telling you that you will NEVER SPEAK TO A HUMAN. Didn't understand what I was asking or wh

    A good investment for your property.

    These Eufy cameras are very well built, they perform as they should, (minus some hiccups every now and then, although I attribute this to software issues), however do wait for sales on them. I normally purchase mine once the price drops to around $170 - $180 which i think is a better price than ~$240I have purchased three of them so far for three sides of my house. The illumination is good, one can increase of decrease it. The two way audio is pretty crisp and loud (does have volume control). There are plenty of features to customize how you want it to perform, and the app is easy to learn to

    Excellent Eufy Security Cameras Experience

    We purchased two of these Eufy 4K double camera units with 2K floodlights. We have been using Moto cameras for a few years and we’re not happy with them because they missed a lot of things and sometimes didn’t work. We had a higher failure rate on the seven units we purchased then anticipated. And now they want you to buy a plan and they have constant interruptions to access your cameras with advertisements. Through research we found great reviews on Eufy security cameras. With a no cost plan and ease of set up and the fact that they will track movement and record them with the SD micro card.

    Upgraded from S330

    I've had my eufy S330 floodlight cam for almost three years. It's been working extremely well and I have no particular complaints about it. However, I want all of my wired cameras to be recording 24/7. The S330 and models from that generation of eufy cams only used their on-board memory and only allowed recording upon a triggering event. So, when I saw that they upgraded this model with the ability to record 24/7 to micro-SD along with adding the second camera and it was on sale, I didn't hesitate purchasing. Over time, the S330 has accumulated a few ounces of water in the protective dome unde
