1080P PTZ cameras can be expensive and sometimes cost thousands. They also may require special power supplies and can be large. The Dahua SD42212SN-HN has 12x optical zoom, pans and tilts quickly, can work with the included power supply or you can use a PoE+ injector, is smaller in size than other Dahua PTZ cameras and comes with a street price of under $500.

This is the dome version of the Dahua IPC-HFW2300R-Z zoom bullet I recently reviewed. What makes this one interesting is that it’s a small mini dome allowing for more discretion than it’s bullet sibling. It uses the same Aptina sensor Dahua used in their higher end costlier line of products making this more of a bargain compared to their vari-focal models.
Outdoor zoom cameras tend to be pricier than standard varifocal lens cameras and those tend to be pricier than fixed lens cameras. Dahua broke the price barrier offering a 2.8-12mm zoom camera for not much more than their standard fixed lens mini bullets. The camera has a new attractive look and surprisingly smaller than Dahua’s or Hivision’s current varifocal bullets. I call it a zoom vs. a motorized varifocal because it auto-focuses as it zooms where motorized varifocal cameras have a two step process where you set the field of view, then click to focus.
This is Dahua’s latest mini-dome and it’s tiny and priced very competitively at $129.99. It uses a 3MP CMOS sensor but at the moment displays a maximum of 1080P at 30 fps. The camera delivers good image quality, good responsive interface in a well built compact dome without some of the issues I ran into in previous mini domes I’ve reviewed.
This is one of Dahua’s latest PTZ cameras with IR LEDs and 30X optical zoom. If you have lower zoom needs, the same camera is available with a 12X zoom as the SD59212S-HN. What makes this camera unique from other PTZ as well as other IR PTZ’s from Dahua or Hikvision is that it can tilt up 15 degrees above the horizon. If you have ever owned a PTZ, you know what I mean, very annoying when you can’t see past the horizon. If you compare this to prior IR PTZ’s from Dahua, this one is considerably smaller. What also makes this PTZ unique is the more affordable price.
Dahua is now offering it’s “Lite” series and this is their flagship camera in this new series. It uses a 3MP CMOS sensor but at the moment displays a maximum of 1080P at 30 fps. So what makes this camera “Lite” is the low price because feature/functionality, this cameras is on par with others priced higher. The camera delivers with good image quality, good responsive interface in a well built compact mini bullet.
Dahua is now offering it’s “Eco-Savvy” series using the Aptina 3MP CMOS sensor vs. the 3MP Sony Exmor CMOS sensor used in other models. This new camera uses <5W of power vs. <6W on the 2MP mini bullet, the IPC-HFW3200S. Cost from U.S. distributors seems to be close to the 2MP IPC-HW3200S. Image quality has different characteristics over previous 1080P and 3MP cameras from Dahua.
This is Dahua’s mini IR dome. It’s is sort of a cross between the easy aiming and flat glass front lens of a bullet camera but with the compactness of a dome. While it has the same sensor as the mini IR bullet, the ipc-hfw2100, it seems to do better in low light at night and better with white balance issues common to that camera.

A short while back I reviewed the Dahua IPC-HFW3200C that was an excellent 1080P surveillance camera at a low price. For about $15-20 more, Dahua offers the IPC-HFW3300C, identical in every way to the IPC-HFW3200C, but has the option of 3 MP resolution (2048 x 1535). The sensor is a little larger to accommodate the extra pixels. Image quality remains the same during the day or night.
The previously reviewed Dahua cameras used a CMOS sensor, this is from their megapixel CCD line. The theory with CCD’s is they provide better low light capability but I feel the balance has tipped and there are some really good CMOS sensors now including the Sony Exmor sensor used in other Dahua cameras. The advantage of this dome over the previoulsy reviewed mini dome is that it has IR illuminators built-in.
After reviewing a few Dahua cameras the next logical step is to review their NVR. This model, the NVR3204 I tested is the 4 channel model available for as little as under $300. They also make 8 (NVR3208) and 16 (NVR3216) channel versions priced $329 and $349 respectively. This is bargain compared to other NVR’s or the alternative of setting up a PC with NVR software.
It was fairly easy to set up, the menus are responsive and the interface is intuitive. More like an iPhone app than Windows PC. Has HDMI output so it can be used with a large screen TV or on a computer monitor using the VGA connector.
Here’s an outdoor rated mini bullet that fits smaller budget yet does a very good job for less money than it’s rivals. In comparison to the Dahua mini dome I reviewed that costs the same price, it has 1080P resolution (or 2MP) and this camera forgoes resolution down to 1.3MP for more features. Most importantly is that it’s a true day/night camera with an automatic IR cut filter and it has a very bright IR illuminators making is usable in dark situations.
