The active deterrence is kind a gimmicky, especially the TIOC with the blue and red lights.
But in your situation, where you are not after the high quality images that say the 5442 offers, they do fill a niche.
If you want active deterrence, your best bet is to go with the 2MP IPC-T5241H-AS-PV that will blink the white light (or you can leave it on all night or just come on solid with motion - a lot of options). This is on the ideal MP/sensor ratio and will perform comparably to any similar 2MP fixed lens camera by Dahua. I have two of them. I have some of the other active deterrence cams as well, and would opt for the 2MP in every instance except for indoor, one could go with the IPC-HDW3449HP-AS-PV that has the red/blue lights that will bounce off the walls and be much more impressive than outside. Outside the red/blue light is more gimmicky than anything else. Nobody will see it unless they are looking at the camera. And the distance isn't very far due to not being an ideal MP/sensor ratio.
Stay away from the IPC-HDW3849H-AS-PV as it has been well documented
here how horrible that one is.
You can make it siren or say "You are under surveillance" or add your own audio.
The video quality at night is comparable to any similar camera on same sensor and lens size. The biggest problem is people buy this camera expecting to IDENTIFY at 60 feet and no 2.8mm or 3.6mm will do that. But if you are under 15 feet it will be ok.
I will warn you the lights are piddly and will only be seen in complete darkness or if the perp looks directly at it. We have seen motion activated lights are not a deterrent.
Watch this video someone posted and how the floodlight comes on and they don't even flinch. But then the audio comes on and they don't know which way to run LOL.
