For years, I owned a first-generation Arlo camera system, and generally was pleased with it. But when eufy came out with its systems, I decided to update to the newer technology.
I am disappointed in the eufyCam E cameras for several reasons:
My eufyCams do not trigger videos until a moving subject is almost directly in a straight line of sight from the camera. If a subject enters an activity zone, it is not picked up until it is almost directly in front of the camera. If the subject is 10 to 15 degrees off the front of the camera, it will not be detected. (My old Arlo cameras have a much wider area of sensitivity.)
The range of the eufyCams is poor. Anything further than about 10 feet from the cameras is not picked up, even if the movement is well within the activity zone. (My old Arlo cameras would pick up motion not only at my front door (8 ft. away), but on my driveway (20 ft. away) and my mailbox at the curb (30 ft. away. All of these spots are in different directions.)
My eufyCams, with only 2 LED lights (Auto night vision is on), make it almost impossible to recognize people at night. (My old Arlo cameras have 12 LEDS (!) and light up the recording area nicely.)
Note: I am well aware of the limitations of wireless cameras, including lag time, reach, etc. But my eufyCams are mounted in the exact same spots as my old Arlos were, but the Arlos performed much better. In addition, the Arlos had the ability to trigger other cameras when motion was detected in one camera.
Three things I DO like about the eufyCams are the sirens, the two-way audio and the long battery life. However, later Arlo models have added these features, so I may take another look at them.
