Did you test these for the voltage range and power consumption? I saw there was voltage measurable at the camera voltage input when powered through PoE. Maybe one could grep the voltage from the PoE powered cam, because the power need of the mic is very low. Actually I don't know what I've measured. I assume it was about 9.xx volts.

I'm sorry @Crazykiller, I have never installed or tested the above mic. Only the $20 Microseven mics. They have an input voltage range of 8-20V DC. Not sure what's available from the pass thru?

Would be interesting if the Microseven would work with the voltage which is available at the power connector from the cam while powered through PoE. And of course if the cam is still stable when sucking some current from the cam
Maybe I'll try this with a cheap Chinese domestic model first. But at first I'll need to get a mic. Seems the microseven would be hard to get in the EU.

Although that's the 12x version, the SD49225 has the same inputs/outputs. You have to add an external mic to it, which can be beneficial anyway as they are extremely sensitive, and not really pricy.

Two recommended mics are:

This outdoor waterproof mic from Amazon is solid. I have installed 5 so far on 4 - PTZ's and an HDBW5231.

External mic with power pass thru, again from Amazon.

I recommend these connectors for a simple clean install.

I have the VideoSecu mic as well as the Microseven. The M7 is a multitude times better. IMHO

Hi everyone.
I'm sure glad I've came across this topic.
Bought 2 cameras from @EMPIRETECANDY through Aliexpres storfront, got them couple days ago. Exelent service, very fast shipping times.
I came from foscam PTZ then Sunba PTZ and now this sd49225t-hn so you guys can imagine how ecstatic I and wifey are about this cam.
Ordered one more and when Andy has more stock wife wants another one .
Still learning about the cam. Currently recording to Unraid NAS. Also have couple Hikvision bullets and couple Hikvision minidomes.
Need some advise:
1. NVR or PC recording?
2. If NVR what model do you guys recomend (brand).
3. What URL would you use to for example to go to preset 2 and start recording (trying to integrate with HA). My HA controler is isy994izw by Universal Devices.
4. If future firmwares are available from Dahua can we upgrade ourselves or have to wait for Andy with custom firmware.
Thanks
PS. Because of the size of property (rural) I would rather go with individual POE injectors then central POE switch(POE NVR).

Well after some reading and experimenting I can partially answer:
3. http://<ip>/cgi-bin/ptz.cgi?action=start&channel=0&code=GotoPreset&arg1=0&arg2=1&arg3=0 ---this will go to preset 1.
4. Looks like as long we use right firmware for right camera we can upgrade. (would the camera let you use wrong file and brick it?? )

I want to thank Andy for very fast shipping and no tax with UPS in Italy SD49225T-HN + PFA120 cam works perfectly, Thanks.

Trying to order a camera today from Andy's site but it isn't working right now. Grrrrr...

I put up one of these at a remote radio repeater site today, and this is how it sees now in the middle of the night when I crank up the exposure, gain, and iris settings to the max.



No artificial lighting for about 10+ miles. The moon is currently only 8% illuminated! I hope these manual exposure settings allow the camera to behave decently during the day, because Dahua's automatic profile switching sucks. I'll probably have to rig up a sunrise/sunset profile switcher.

I recently added a 3rd 49225T-HN camera. I now have 2 of them located in the back of the house. This camera is dedicated for the view only and is forced in color mode 24/7. All the other settings are at the camera defaults. Here is the view at night.

Is that using the 1/3 shutter speed? Have you tried it in forced color mode at night?

 

[ShawnInPaso]

Well @EMPIRETECANDY is out of stock on these cams now. Hopefully there will be more to come?

oooh, have enough stock, i just put on some stock on it.

 

[ShawnInPaso]

Thanks @EMPIRETECANDY but I can only see PAL in stock and I need NTSC.....

You don't need ntsc, it's digital. And if you really feel a need for ntsc and 60fps, then you could flash the firmware to ntsc.

 

[ShawnInPaso]

Hey Ck - Thanks for the info. Goes to show my ignorance and not thinking it through (although it does beg the question why they force a choice). Anyway, I'm off to go make an order now - very much appreciated !

Looks like a wireless version of this camera will be available in the near future. Looks interesting.

Installation finished yesterday

 

[Parley]

It looks like you can use standard POE if you do not use the IR. Without the IR it is rated at 13W which would work with my Hikvision NVR. So I am thinking about getting one of these.

 

[Crazykiller]

Got my fittings today. But this week it's raining cats and dogs like in the rainforest, so no chance for an install.
I'm glad i already pulled some pipes from the attic to the roof overhang a few days ago. So it would be easier to get some cable there when I'm ready for install.
