In our test, the camera settings are simple and easy to understand. It provides enough functions and controls to adjust the camera to most situations. Our tester advised this Hikvision IPC is easy to install and configure, very durable and reliable and able to stand up to a lot of elemental exposure. One of our regular clients recommend this model is an excellent product, he will definitely recommend and use in future.

In previous generations, dome cameras were subject to IR glare (whereby IR light would bounce off the inside of the dome and "blind" the camera). But now Hikvision has rectified a lot of those issues with newer generations. It now comes down to aesthetics and which one you like the look of more when compare dome cameras to turret camera. Especially some customers still calling Hikvision’s turret camera Pig Nose camera.

Our installer reported the motorised lens did help with typical one-man installation. Especially when you would like to zoom and focus the camera without any help as you don’t have to reach the camera to do the focus. Compare to Bullet camera and Turret camera, dome camera may take more time to zoom and focus if there is no motorised function.

We did focus the camera to an area where there was a strong light with shade in the same picture, DS-2CD2755FWD-IZS’s WDR function did a good job, the result is a balanced picture, you would be able to read the details in the shade with the bright area clear too. We are happy with the result which achieved by the testing model.

The Hikvision DS-2CD2755FWD-IZS dome IPC is an Easy IP 3.0 Series Network Camera, it is inexpensive yet provides good performance. It has enough adjustments, can be used in many applications where limited advanced functions are required. At a selling price of around $330, it is a very economical solution that provides excellent cost performance for many applications.

Hikvision EXIR 2.0 Infrared Technology by BigPack Wholesale

In surveillance industry, with the growing popularity of the all-weather monitoring, the requirement of IR LED is getting higher and higher. And the brightness, reliability as well as lifespan become vital indexes for camera’s quality. Perfect night view is important to professional surveillance systems, it built up from advanced technology, not just a thing of LED chips.

Initially, DIP IR LEDs with diameter of 3 mm, 5 mm, 8 mm were wildly used by camera manufacturers. However, Hikvision, as forerunner of the infrared camera, took the lead in developing EXIR camera a few years ago. With the boost of market demand and continuous technical progress, based on EXIR 1.0, Hikvision officially launched the new generation infrared technology, EXIR 2.0.

No IR Reflection or Bleeding. Having the IR LEDs housed independently from the camera lens completely eliminates the chance of internal IR reflection and IR bleeding which can be a problem with dome cameras in particular. A curved, reflective glass dome cover can inevitably reflect the IR back and blind the camera which we've covered before, and an EXIR camera doesn't suffer from this, allowing Hikvision to install stronger EXIR LEDs with no risk.

Better IR Coverage. Traditionally, IR has been integrated in a circular array of many LEDs around the lens. This brought with it the common problem of a circular overexposed area in the centre of the image, with the corners being underexposed due to an uneven IR coverage. The rectangular EXIR LEDs provide a much more even coverage across the entire image, eliminating this issue.
Long lifespan. Under the condition of the same heat dissipation, EXIR 2.0 enables longer lifespan because of its better heat dissipation performance. For EXIR1.0, its lifespan is about 20000-30000 hours, while for EXIR 2.0, it’s about 30000-40000 hours. Compare to DIP LED which is less than 20000 hours.

Long infrared distance Benefit from the improvement of software and hardware, EXIR 2.0 provides better infrared effect for near-to-mid-range cameras (infrared distance within 80m, focus with 25mm), better meeting the needs of the near-to-mid-range market.
Better weather resistance and temperature resistance. The main ingredient of DIP LED’s sealing glue is epoxy resin. While for EXIR 2.0, it is silica gel which enables better weather resistance and temperature resistance.

Higher brightness, less power consumption. Luminous power which refers to the optical radiation power under nominal power consumption is an important parameter to evaluate LED chips. Larger luminous power means higher brightness. The luminous power of EXIR 2.0 LED is about 350mW. And for DIP LED, it’s about 25mW. Thus, one EXIR 2.0 LED’s brightness is equal to that of 14-16 DIP IR LEDs. The brightness of EXIR 2.0 is higher, so compared with DIP LED, its infrared board is smaller under the same brightness. Consequently, it can be applied to camera with smaller size, bringing customer more choices.

Hikvision Anti-IR Reflection Dome Camera by BigPack

Dome cameras have very attractive appearance compare to Turret cameras, many customers said it is difficult to tell the direction of a dome camera, which provides more security than other cameras. But CCTV professionals prefer to keep dome cameras inside of the building, as rain, dust or light on street always make IR Reflection on picture during night view, which is the major problem of dome cameras even some top brands in industry.

Now, Hikvision comes up with an anti-IR reflection solution that can avoid the IR light reflecting to the lens and effectively improve the image quality at night.

First of all, let’s explain where the IR Reflection comes from.
The most of the dome cameras are composed by the camera module and the bubble. The bubble can protect the camera module from dust and water, and extend the lifespan of the camera. At night, the camera emits IR light to all directions to capture clear images. For the ordinary dome camera, there is a lightproof ring placed inside the dome cover, which can prevent a part of the IR light directly entering the lens. Even so, some of the IR light still enters the lens after reflecting for many times in the bubble wall. As a result, those lights enter the sensor and make the image dimness. Especially, if there’s dust or water on the bubble, the IR reflection influence gets more serious. Obvious white spots appear on the image, which will badly reduce the image quality.

Therefore, how to solve the image quality blemish caused by the IR reflection is the most concerned problem for the IR dome camera development.

Secondly, how it works.
The Hikvision anti-IR reflection dome camera adopts the EXIR lamps, a bubble that composed by separated IR passing zone and imaging zone, and the new-type 3-axis adjustment. With the several new technologies, the IR reflection problem is solved.

Hikvision anti-IR reflection camera adds a black U-shape lightproof loop on the bubble, which can effectively absorb the reflected IR light. The anti-IR reflection bubble is divided into two parts: the imaging zone and the IR passing zone. The two zones are separated by the lightproof loop. Without the IR reflection problem, the camera is able to provide a better image when the IR light is on.
• Ordinary Camera: There’s no shield between the lens and the sensor. The IR light will be reflected by the inner wall of the bubble, and then enter the lens and the sensor, which will influence the image quality.

• Hikvision Anti-IR Reflection Dome Camera: The bubble is composed by the imaging zone, the IR passing zone, and the lightproof loop. The lightproof loop separates the imaging zone and IR passing zone and can block the IR light out of the imaging zone, so as to protect the image from the IR light reflection influence.

At night, most of the IR light passes the IR passing zone, while there is still a part of IR light radiates to the lens, and the lightproof ring can block only a few of it. Since the lightproof loop is placed between the IR passing zone and the imaging zone, it can absorb the reflected IR light,
therefore reduces the IR light that enters the lens and improve the image quality at night. In addition, the bubble is a one-time molded assembly that is hermetic, simple constructed, stable and reliable. It makes the dome camera more reliable and covert.

Since the lightproof loop on the bubble is the key to prevent the IR light reflection to the lens, the position of the lens, the IR lamps and the lightproof loop is important. The IR lamps should be kept in the IR passing zone and the lens should always face the imaging zone.

Hikvision anti-IR reflection dome camera has integrated the camera module, IR lamps and the back box. The camera module is hinge jointed with the back box, and the IR lamps are fixed on two sides of the camera module. The camera module and the IR lamps are adjusted together, therefore the IR supplement direction is always same as the lens direction.

The dome camera has unique fixing holes for the bubble, which synchronizes with the camera module all the time. In this way, the camera module synchronizes with the imaging zone and the IR lamps synchronize with the IR passing zone.

Finally, we tested these cameras by comparing Hikvision anti-IR reflection dome camera with ordinary IR dome camera (World Top Class Brand).

Smear the same amount of dust on the surface of the bubble and compare the image. The image of the ordinary dome camera turns gray and dimness, while the image of Hikvision anti-IR reflection dome camera is still clear.

Spray the same amount of water on the surface of the bubble and compare the image. The image of the ordinary dome camera turns gray and dimness, while the image of Hikvision anti-IR reflection dome camera is still clear.

Hikvision anti-IR reflection solution has effectively solved the image dimness caused by the IR reflection and ensures the image clear at night, which can be applied on all kinds of IR dome camera. The anti-IR reflection dome cameras can be widely used at indoor and outdoor environment, especially the dusty and rainy outdoor environment.
