Why Buy Dahua?

So I am the original poster here. I am wanting a PTZ camera that doesn't cost a fortune and has decent night vision. What are your recommendations?

Hard to beat the SD49225T-HN for value (Dahua PTZ). No tracking of its SD59 big brother, but tracking doesn't work as well as everyone's expectations. The SD49 family (12x & 25x) is in the low $300 USD range, and the SD59's are $500+ USD. They use the same starlight sensor.

If you have the right situation the auto tracking can be very useful and accurate.. takes testing trial and error but I'm more than satisfied with mine

I totally agree, but there are others that don't. They work as advertised for my intended use. I have 3x SD59's and an SD6AE in service and they are great. I also have 2x SD49's and they are impressive in low light as well.

Yea if you have wide open views the 59225 tracks awesome.. basically 9/10 times perfect tracking for me if not better.. only time I loose an object is if it blends in with this snow or shadows and sky interrupt.. this is very rare in my situation..

Yeah. Well. Unless you're one of the many users who are at their wit's end with their SD49225T-HN B R I C K. Have a read of this topic before purchasing a SD49225T-HN...

SD49225T-HN frequent restarts

And here's the image my SD49225T-HN displays 90% of the time...

I've been burned by cheap dvr/cam setups several times. As the posters here always say, the nightvision never meets expectations, and in my experience with at least 7 different brands of cameras and at least 5 or 6 dvr setups, usually after a few years one or two of the cameras start acting weird like the nightvision dies or the camera fails completely. I started using blue iris with Amcrest ProHD ip cameras and I'm pretty happy with them. Haven't had a single issue so far in over a year. The nightvision is great, the quality is great. The only thing I don't like about them is the image is distorted on the edges sometimes, like if a vehicle is parked by a camera it looks like one of those celebrity paparazzi photos where the person on the edge looks like a paper cut out and stretched or something. Can't remember the name for that. When I was looking the Amcrest seemed like a good compromise for price and quality, as I needed about 5 of them and got them for about $70 each. I have about a dozen old leftover analog D1 cameras from other kits that I haven't found a use for yet. Don't really want to waste the storage space on bad quality cameras. When I need another camera I will probably buy a Dahua to test it out.

If its a wide angle lens, that's just the nature of the beast. A $2000 ultra-wide professional DSLR lens will give the same stretched effect to anything too close to the edges of the frame if its keeping straight lines straight (rectilinear). My 2.8mm Dauhas are slightly fisheye so objects near the edge are less stretched and more curved.

I didn't suggest this one, because currently there are some serious issue's with the firmware and reboots.

Obviously not. But if you have compared, or read the many threads here comparing the difference between the 2MP Starlights and most anything else in the sub $200 range, you'd see the difference.

Not my problem that some folks are satisfied with shitty nighttime video because they dont want to spend another $1.83 on their electric bill.. to each his own.
