Well here we go. I dont see anywhere more approriate to discuss this. Ive been messing around with putting together a cctv system for close to 3 years now. Ive bought everything i needed and also bought 2 cheap cams from a third party seller on walmart. Those cams cost me a grand total of $50 for both with included hardware. I am quite happy with the video quality those cams put out @that price. (it was a special deal therefore its not currently at that price or id buy more) I also dont live in the fanciest of neighborhoods and the main reason im installing these cameras is to monitor any suspicious activity throughout the perimeter of the house. I get the whole idea of being able to ID a person being critical but i also have a budget in mind.

From looking at all the camera talk ive seen on these forums i thought sticking with dahua might be the best choice for me. However, i dont think i have the budget of most people here and therefore i am looking for dahua or chinese alternativees that would rank in under $100 each. I do plan on buying a starlight or two in the future for key areas but not right now. I also realize people are going to say "but a starlight is only $50 more" and the point is i want something under $100, $100 is my max and id prefer to be under that. I just want to start setting up these cams so i can have a basic functional cctv system. Since Dahua is basically a wholesaler it is very confusing not to be able to choose a product by sorting by price/features. And as someone who isnt an installer or doesnt turn this into a hobby, that is where i start getting lost and ultimately just put this whole idea on the backburner everytime im back here. I figure everyone here has already had experience with dahua or copycat chinese cams and so thats where im asking for help.

I see the low cost entry dahua N22AL12 but that is a dome cam and id rather stay away from domes and stick to turrets/bullets. I am currently monitoring the ipc-t2431t-as-vs-chinese-hdw4433c thread but would appreciate any other suggestions.

For under $100 the IPC-T2431T-AS-S2 is a pretty good camera. I just picked up one from @EMPIRETECANDY for $79 a couple of weeks ago. This is the second one I have and am using them in my garage, both are 2.8mm lenses. Below is a comparison to the IPC-T5442TM-AS, quick and dirty snapshots from BI.

These are taken at night. I was walking from left to right here. There are coach lights on either side of my garage and a street light at the top right. The 5442 definitely is superior, but at almost half the price ($79 vs $154) the 2431 does a decent job if all you want is to monitor the exterior. Depending on the amount of light, you might still get good facial features if the perp pauses long enough. I did not try to adjust the setting for the best possible shot, just have everything on defaults.

FYI, amazon has this rebranded Dahua, the "Amcrest 5MP UltraHD Outdoor Security IP Turret PoE Camera with Mic/Audio, 5-Megapixel, 98ft NightVision, 2.8mm Lens, IP67 Weatherproof, MicroSD Recording (256GB), White (IP5M-T1179EW-28MM) " for $60, I tried a Promo Code I got a week ago for $10 and it was still good on Wed. 5/13 @ 0735 Central. The code is LH4QSBYQ . Hard to beat a POE turret with Starlight tech & built-in audio for $50 plus tax, IMO (not to take absolutely anything away from Andy or @samplenhold 's great endorsement).

man, I hate when y'all post this kind of stuff - it comes to $54.11 to my door and I don't need it - but I am sooooo tempted to just get it anyway. :idk:

Agree. I bought it. I have a 1.3mp 8 year old mini-bullet to retire....
I put in the promo code at 7:30 AM to see if it worked (it did) before I told ya'll.
I've been gone all day, went and got a haircut, bought some bagged topsoil, moved a yard of dirt with the tractor, cut/hauled limbs, etc.
Read your post just now at 4:00 PM Central and said to myself "...Tony it's been 9 hours, if that $10 promo code still works then order it, if not, no biggie."
Well, I'll bet you already know....just got it for $53.99 delivered.
Even if its low-light performance isn't that great it'll be OK as it'll be looking at Old Glory which is lit dusk to dawn.

I may have discovered why this one is Soooooo cheap...

This apparently is a native 4:3 sensor, and they "squeeze" the image into a 16:9 aspect.
Here is a shot from my cam with the "default" resolution of 2688x1520.
I am 6'2" and 225-- and "squished" in this pic.

I noticed this, and messed with resolutions. Another resolution on the cam is 2592x1944 I think this is the TRUE native sensor resolution...

So my guess is that they got these sensors for dirt cheap and slapped them into a compatible Dahua board/processor. I would be OK if this camera CROPPED the image to give a 16x9 ratio--- but Compressing/Distorting is crapola!

On a side note.... it's time to stain the deck again....

A 4:3 aspect ratio is preferred in many applications. The issue with the sensor is that it’s not a good low light performer.
Interesting-- I thought 4:3 was essentially dead. Don't you find it odd that they compress the pixels to 16x9 instead of cropping them?
My old 1.3mp Dahua bullets (from 2012-- still have 3 working) display at 1280x960 or 1280x720 (70 pixels cropped top and bottom). That kind of cropping makes more sense to me than distorting the image.

Dahua has a bunch of new cams with 5mp 4:3 sensors. Remember amcrest doesnt build anything. Dahua makes it for them. 4:3 is preferred over 16:9 in areas where you want to get more high in the image particularly near the camera, front door, a full room etc..

Yup-- I knew Dahua made this one-- it matches the 4mp cheap ($80) one I bought from Andy, and the Amcrest firmware is clearly the Dahua firmware with a new "skin" applied. I wonder if a pure Dahua firmware on this would give me an undistorted cropped 16:9 ratio image resolution... hmmmmmmm. If I knew a given Dahua firmware would work and not brick the thing, it would be worth it to me for that.

I paid 60 and I am pretty happy with that cam. Wish they had a 4mm option or 6mm but it's relatively new. For $60/50 you can't beat it. If it's defective out of the box Amazon can rma it.

FWIW, there's also a 3.6 (IP5M-T1179EW-36MM), I got the 2.8 (IP5M-T1179EW-28MM) .
Yes I have the 3.6mm version. I'm hoping it popular and later they add a 4/6mm option if the volume is enough.

Did anyone try to convert it to Dahua firmware
I assume it's N53AJ52 OEM model

N53AJ52 firmware failed. But the firmware for the IPC-HDW2531T-AS-S2-same camera??-works.
Shows device type as IP5M-T1179E.
I have yet to test anything other than logging in to a Dahua menu so proceed with caution.

Very interested in if that works. What's necessary to install it?

I did have to do a factory default after the firmware update to remove the Amcrest logo.
Just keep in mind you'll revert to a static IP that's likely outside of your subnet.
You can use the Dahua config tool to find the camera and change the IP. Dahua Wiki
