Smart illumination set up new cameras
- Thread starter eventlights
- Start date
You would have thought yes.
But obviously has some sort of detection, as I set up trip wire and had the red and blue leds and siren working with movement, I would have thought that would link to turning on and off the white led with movement as well
In that version the white light isn't linked to any AI features.
It should be a simple turns on when the light level is too low for a colour image.
FYI even the newer TiOC 2.0 the light is triggered depending on the motion detection / SMD zone, not the IVS rules.

Thanks again mate, was doing my head in trying to.work it out, never occurred to me that it didn't have that feature being a new 4k camera, ahh well least it wasn't user / installer error. Have a good one
Sadly, you have fallen for the chasing MP trap. Are you able to return them?
You want cameras with MP/sensors in GREEN.
Most here will say that 4MP is the sweet spot for these types of cameras.
See this thread for the commonly recommended cameras (along with Amazon links) based on distance to IDENTIFY that represent the overall best value in terms of price and performance day and night.
The Importance of Focal Length over MP in camera selection
Unfortunately your camera is an active deterrence camera on an 8MP on a 1/2.8" sensor, so it is on a horrible MP/sensor ratio. You cannot have enough light at night for it to perform well. That sensor is designed for 2MP so a 2MP camera will kick its butt all night long.
Even worse, since this 8MP is on the same sensor and CPU as a 2MP non TIOC camera and there are many threads here showing how under-performing that 3849 is. They had to limit bitrate and other parameters on the 3849 to try to make it functional, and it just doesn't cut it.
This is what happens when someone chases MP over sensor and this camera is the epitome of that thinking.
Further, the red/blue flashing lights are more gimmicky and are certainly not a deterrent. With any ambient light you won't see the red/blue flashing unless you are looking right at the camera.
If you want active deterrence, your best bet is to go with the 2MP IPC-T5241H-AS-PV that will blink the white light. 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.
Lot's of threads here where people showed how bad the 3849 camera is in performing:
IPC-HDW3849H-AS-PV issues
IPC-HDW3849H-AS-PV loses connection/reboots during the day
Replaced HDW5442TMP-ASE by HFW3849T1P

Thanks for the informative reply, I took a look at the links you added as well, pretty well sums it upSadly, you have fallen for the chasing MP trap. Are you able to return them?

I had read about the trap of chasing higher MP so probably should have known better but was thinking with a motion activated LED for additional light I may be able to live with the reduced night performance v better day light image for my situation, but having the LED on continuously at night was not what I was expecting.
Why the hell isn't the LED motion activated, makes no sense?
My 5MP cams do a pretty good job both in daylight and at night with IR and motion activated white LED,
I will look at your recommendations and the MP v sensor chart you added and replace these 4K units, which alas I can't return. Mayb I can find a use for them elsewhere! Dammit.
Thanks again appreciated
This chart was developed based on the collective input of many members here with real world experience with many/all of the different cameras out there. If you want good night-time performance, you need cameras with MP/sensor ratio in the green.
You also will see a price correlation between those in red (cheaper) versus those in green (more expensive than those in red).
A 4K on the 1/2.8" sensor will always be cheaper than 4K on the ideal MP/sensor ratio.
Generally the larger the sensor, the more light that can be captured per pixel.
I have a 4MP and 2MP on the same 1/2.8" sensor and the picture quality is quite different between the two and the 2MP kicks it's butt at night.
My 4MP on the 1/1.8" sensor performs better than my 2MP on the 1/2.8" sensor. Even though they are both ideal MP/sensor ratio cameras, the larger sensor has the advantage.
In most instances, you want to get a camera that will perform at your location for the worse situation, which for most of us is at night when it is dark and there is little to no light. If a camera performs at night, it is easier to tweak settings to make it work during the day than it is the other way around.
My 2MP cameras outperform my neighbors 4K (8MP) cameras....why....because they are both on the same size sensor.
So if low light capability is what one is looking for, you want to be looking for cameras that are on the ideal MP/sensor ratio.
Absolutely. Good luck. Like we said, the most common cameras we see installers put up are 5MP on the 1/2.8" sensor or 8MP on the 1/2.8" sensor and both are cheap lower level cameras in the manufacturer product line.
You are falling for the biggest mistake people make - chasing MP and thinking digital zoom works. Digital zoom only works in the movies. You might get away with some digital zoom, but you need optical zoom which is real time zoom (like binoculars or a telescope as an example).
You need to chase focal length and sensor size as I point out in this thread. At 60 feet, a 2MP with the proper focal length will ID all night long whereas an 8MP on a 3.6mm focal length will be blurry.
Here is an example from @Ri22o of a 3.6mm focal length 8MP 180degree camera view versus a 2MP varifocal OPTICALLY zoomed in to a pinch point. The person is next to the green line on the left:
And now a 2MP varifocal optically zoomed in to that area in green:
Which one is better for IDENTIFY? There is no way you would have been able to tell it was a male, in a red, flannel shirt, with sunglasses, and a receding hairline in the 8MP wide-angle 1st image.
You would have to set the camera up specifically to read plates. You need the proper camera with OPTICAL zoom for the distance you are covering and the angle to get plates.
Regarding plates, keep in mind that this is a camera dedicated to plates and not an overview camera also. It is as much an art as it is a science. You will need two cameras. For LPR we need to OPTICALLY zoom in tight to make the plate as large as possible. For most of us, all you see is the not much more than a vehicle in the entire frame. Now maybe in the right location during the day it might be able to see some other things, but not at night.
At night, we have to run a very fast shutter speed (1/2,000) and in B/W with IR and the image will be black. All you will see are head/tail lights and the plate. Some people can get away with color if they have enough street lights, but most of us cannot. Here is a representative sample of plates I get at night of vehicles traveling about 45MPH at 175 feet from my 2MP 5241-Z12E camera (that is all that is needed for plates):
See the LPR subforum for more details.
Had a long chat with the guy at the SSAIB ssite, re my installer. The upshot was he thought it would be better to make the installer an offer for the cable and bridge installation, and see what happens.
I also need to get to grips with the VPN thing. This Dahua stuff seems incredibly and unnecessarily complicated - I bought a Tutis with one camera back in the '80s or '90s, and it still worked when I replaced it witth this stuff. That said, it's resolution was grim
.
Which system would you recommend assuming I could get it in UK?
I'v attached a shot from Googlemaps showing my place.

You have to remember that we are not the Dahua and Hikvision intended audience - it is the installers hoping you will subscribe to their monthly fees to "manage" the system. Although it does appear Dahua is now trying to enter the home market.
The better camera manufacturers figure people will use another platform for their VMS needs so they don't invest a lot in their app whereas the consumer grade cameras know the app experience will be what drives sales and they invest in the app.
The consumer grade companies invest more in their app experience because that is what is driving their sales are a consumer that wants the ease/simplicity/simple setup and app more so than camera quality.
Nothing in this arena is true plug-n-play if quality and able to IDENTIFY is important.
All cameras need to be dialed in to the field of view. Even the best cameras left on default will result in motion blur and ghosting at night. It is the same process for the dialing in the camera regardless of the VMS (NVR) system used.
If you want true plug-n-play simplicity and do not care about nighttime motion quality, then go with one of the consumer brands - Ring, Arlo, Reolink, Nest, Blink, etc. They are true plug-n-play because those cameras all run on default/auto settings with very little, to no ability to change camera parameters. But they do usually meet the WAF criteria.
Simply download their app and scan the camera QR code and you are up and running, with a better app experience also.
But their plug-n-play simplicity comes at a cost of nighttime performance and ability to customize stuff, but obviously many do not seem to care about that as those systems are popular and those consumer grade systems are a perfect fit for those that want simplicity and not having to learn how to use an NVR.
But if you want the better cameras, then see this thread for the commonly recommended cameras (along with Amazon links) based on distance to IDENTIFY that represent the overall best value in terms of price and performance day and night.
