Welcome to the forums! 5 to 7 seconds seems to be a little long, but there is a delay for sure when the camera starts recording after an event. The camera is normally in a sleeping or low power mode. When it detects motion through the PIR sensor, that commands the camera to wake up. Now the camera does a second check of the motion to see if it passes your sensitivity settings, then it starts to record. It usually takes a few seconds to accomplish this, but 6 to 7 seems long.
You can test your camera by standing (might be easier to take the camera down from it’s mount and have it sitting on a table or something) out of frame, waiting for the cool down period to end. And wave your hand say 10 times in front of your camera fairly close to it. Now when you see the event in the app, how many waves do you see? Only see 7 waves? 3 waves? Now do the maths on how long does it take you to wave the amount of times that the camera didn’t catch. We can start here for troubleshooting.
Another idea is to have a Wyze Sense contact sensor on the door, so when it opens you can have a rule that commands the wco to record a short video. That’ll give the camera a headstart when there is action in the entryway.
