Most folks find IVS is more accurate than motion detection, especially in terms of fewer false events. That said, neither are 100% accurate so the best practice is to continuously record + record on motion detection/IVS. A lot of us (me included) have learned the hard way that if you're just recording events, you'll eventually have a situation where something doesn't record properly.
IVS may take a bit to get working the first time, but IMO its worth the effort. One of the not-obvious things is that to enable it, you need to go to Events > SmartPlan, select IVS and save that setting. Another not-obvious thing (at least to me) is that if you do a tripwire close to the image's edge, it may not reliable trigger because the camera needs time to notice moment and figure out if it's an object or not. If the object has already crossed the tripwire before the camera identifies it as an object, then nothing triggers. A way to work around that is to use intrusion zone with the option of "appears"... if something actually makes in inside of the boundaries you've drawn before it's classified as an object, it'll still trigger the alert. Oh, when done drawing the boundaries of a box, right-click to say you're done. There have been a few good threads about IVS over the past few years, so you might be able to Search up so more tips.
