Turrets with 1/1.8 sensor?

Sorry for the newbie question, but when I read many recommendations, I come across a lot of comments recommending 1/1.8" sensors with ideally 4MP. Or is this old news and the newer cameras are fine with smaller 1/2.7 or 1/2.8 sensors and more pixels? I wouldn’t mind 4K, of course, if the night performance is still good.

However, seems to me like Dahua hardly offers any models with the larger sensor? Currently I‘m focusing on turrets with the hybrid nightvision like the IPC-HDW3449H-AS-PV (which have all 1/2.7 sensors). The only model with a 1/1.8 sensor, the IPC-HDW3449H-AS-PV-PRO seems hardly mentioned anywhere and not available in Europe…

Maybe I‘m also looking for the wrong cameras altogether? Not sure I need dual light and others seem to have larger sensors, correct? Is there any overview with recommendations on which cameras to buy?

Welcome @Concurra

There are a lot of smaller sensor models that they are marketing for low light now .. that is now that they have added white leds to the cameras.

Avoid those gimmicks and look for better models with larger sensors as wittaj notes.

Some vendors like Andy have access to many more models than our in country vendors, and so you will want to research what is possible for your location.

Thanks. Based on your input, I narrowed it down to the following models for the turrets I need:
  • IPC-HDW5442TM-ASE - Basically your go-to recommendation for $149? Looks all good, though I'd have to simulate which lens works for me (likely 3.6)
  • IPC-HDW5442T-ZE - More flexible than the previous one, which would be nice (particularly given my lack of experience which exact lens to pick) - is the price difference only $30? In this case, I'd likely simply chose the vari-focal version to stay flexible/adjust the field of view perfectly to what I need
  • IPC-HDW3449H-AS-PV-PRO - No clue how this compares, but at least sensor/MP wise the same than the previous. The active deterrence as well as the color night vision when an intruder comes close enough would feel like a nice extra if the rest of the camera performs like the 5442. Not sure about pricing either...

The pro isn't out until late August here in Australia and a contact at Dahua UK hasn't heard of the Pro yet so its coming but no one seems to know much about it yet, none of the official UK or Aus Dahua reps anyway (not that, that says much Dahua is terrible at communication).

Because its more flexible with regard to FOV, I'd get the IPC-HDW5442T-ZE.

If you find a spot where it requires no zoom from the default 2.8mm wide view or just a smidge more, then get the 3.6mm fixed IPC-HDW5442TM-ASE for that spot. Same camera, just one has a small zoom the other is fixed lens.

Fixed lens will typically do a bit better as to light pickup at night, once you start zooming a variable focus camera, your F-stop or the ability to capture light, deteriorates. Around a standard home, it shouldnt be a big deal.

Hi @Concurra if this is your first decent ip camera get the varifocal model to learn with as bigredfish recommends.

If you need more cameras later what you learn with the varifocal version will help you better understand the DORI concept and pixel density and fov relationships.

Alright, I'll get the IPC-HDW5442T-ZE as a start. I also need a bullet - which one would be a suitable equivalent? The IPC-HFW5442E-ZE or the IPC-HFW5442E-ZHE?

And a suitable NVR would be needed as well - which one would you recommend? It's just a home setting, I would only plan 1 HDD and even thinking about future additions, I need max 6-8 cameras, mostly POE, some WiFi. It would be good if the cameras could be connected to an emergency call center that my alarm system is tied to (but nothing I would implement immediately). What else would be important criteria? Are there easy recommendations amongst dahua's range?
 
HFW5442E-ZE is the standard size bullet.
I have the big boy and it is nice, but not enough difference to worry about

The NVR you are calling out is this

But I recommend you step up to more bandwidth, possibility of adding another drive down the road and even more cams

Any objections? 8 cameras are for sure enough for our tiny place… I assume connecting 1-2 indoor cameras via WiFi is possible?

Not sure if there are any features I should pay attention to or any alternatives worth thinking about?

Yes .. if the wifi camera meets standards for rtsp and onvif .. or close enough, with the dahua nvrs you can manually add cameras from the LAN side of the NVR.

get the 16 channel model of the NVR .. even if you think you will max out at 7-8 cameras ..

In general I recommend stepping one step higher than the max cameras you want, as often it happens . People easily hit 8 camera channels and then want to add just one more ..

It's worth pointing out that you can only ever add as many cameras as there are ports on the NVR regardless of how you connect then.

Yes, NVRs have limits. Not the poe ports per se, but what is called a channel.

Some NVRs do not have POE ports, so you have to watch for that when you see a cheaper deal on a 16 channel NVR vs another ..

Most NVRs we look at as a home user will be 8 or 16 channel NVRs .. which typically have the same number of POE ports.
