1. both are not active deterrence
2. dahua camera cannot link LEDs to motion, so they have to stay on the whole night (or you have external white light)
3. hikvision can link LEDs to motion, but all models are already EOL and new G5 firmware is buggy as hell. review is from G3 platform, so you cannot compare it to G5
If you put flashy lights above utlimate picture quality, then go TIOC for all your cameras. If not, consider the Go To's and TIOC maybe for a single location where no-one should ever be and scaring them off becomes a number 1 priority.
I have a single TIOC myself and intend to keep it. In my situation it's ideal for my backyard because if anyone's back there, they're only there for one reason, to gain entry in which case scaring them off becomes the priority, not least of which because hopefully any other cameras I have will have already captured the money shot with TIOC being more of an overview. I also have an all night low wattage LED bulb back there (6w) backed up by 2 led floodlights on a motion sensor that stay on for a couple of minutes when triggered, plus the inbuilt leds should I choose to enable them, so plenty of lighting should something happen. That should ensure a decent picture alebit not one as good as the go to's. I also intend to time delay the TIOC alarm to allow the camers to record some footage untainted 1st.
For all other locations I might want to put a camera, it will be one of the "go to" cameras to prioritise picture over bells and whistles. Be aware once the flashing lights do go off, the picture will likely be degraded and colour tinted by the lights. I did a tongue in cheek review a while ago on here and whilst it has a tongue in cheek element, it nevertheless conveys the main points about the camera.
This video (not mine) at 1 mins shows how TIOC#s flashing lights can degrade the picture in a low light situation once triggered (see @ 1.00 mins):
TIOC serve a purpose and would certainly be within my armoury, but my primary choice of camera for all locations, no.
You can add extras such as microphones to some other cameras although I suggest you check the thread on these subjects for indivudal model compatability and how to's.
You have to ask yourself, if this guy is damaging your car (it would appear to be a grudge for some reason), do you want to scare him off only to possibly have him come back in a ski mask from then on, or do you want to best quality pictures of him for evidence?
One compromise way around this would be have the 2 crossed cameras suggested before and have 1TIOC and 1 Go To and delay the deterrence on the TIOC to enable both cameras to get an unaldulterated picture. Put the Go To on the side he normally walks towards to ensure the facial pic. It's still not ideal as the flashing lights may degrade the 2nd camera, but a reasonable compromise.
One final point, if you set up alerts on your phone that will wake you to any detection, you can trigger the TIOC alarm manually if needed from the interface. Personally I'd either do this or add a delay to enable the cameras to catch a good facial picture before the TIOC features trigger. TIOC are certainly useful but have to be used with an understanding of what you're getting picture quality wise with the smaller sensor and the effect the deterence features can have on the quality. I have one and will use it, but understanding of how best to deploy these is the key.
