Exposure control:

■Exposure level: You can manually set the Exposure level, which ranges from -2.0 to +2.0 (dark to bright). You can click and drag the pointers on the Exposure time and Gain control slide bars to specify a range of shutter time and Gain control values within which the camera can automatically tune to an optimal imaging result. You may prefer a shorter shutter time to better capture moving objects, while a faster shutter reduces light and needs to be compensated by electrical brightness gains.

■Exposure mode:

Auto: If you set Exposure mode as Auto, the Exposure time and Gain control will not be configurable since the sensor library will automatically adjust the value according to the ambient light. Then you can set iris mode as “indoor” or “outdoor” to reach the best image quality.

■Iris mode: Select Indoor or Outdoor iris mode to adapt to the installation. The preset iris aperture setting will apply.

Manual: (Note that some of the Manual options will be disabled when WDR Pro is enabled!)

■Iris Adjustment (available in the Manual mode): The camera comes with a P-iris lens, which controls the iris opening with extreme precision by its built-in stepping motor. Via software controls, the lens maintains the iris opening at an optimal level at all times, resulting in superior sharpness and depth of field as well as image quality.

You can manually tune the value of iris opening (aperture size), which can range from 0 (Close. smallest aperture size) to 100 (Open, largest aperture size).

Once set, the iris will stay at current position as long as the lighting condition allows. When external lighting conditions exceed an acceptable range, the P-iris mechanism adjusts itself.

■Exposure Time: The configurable max. exposure time is tunable according to lighting conditions with values ranging from 1/10000 to 1/5 of a second.

■Gain Control: Tune the slider bar to set the Gain Control to the best image quality. Higher gain control value will generate a certain amount of noises.

You can click Restore to recall the original settings without incorporating the changes. When completed with the settings on this page, click Save to enable the settings.

■WDR Pro : When enabled, you can select the strength of the WDR function. The Low, Medium,

High options correspond to the level of contrast between the overly-lit area and the shaded areas. For example, the High option applies to a high contrast scenario. Note that when the exposure time is set to longer than 1/60 second, the WDR function will be disabled.

The Sensitivity option applies to the response speed to the change in bright-to-dark lighting contrast.

IP8355EH specifications

The Vivotek IP8355EH is a sophisticated IP camera designed to meet the demands of various surveillance applications. With its blend of advanced technologies and robust features, this camera is ideal for monitoring both indoor and outdoor environments.

One of the standout features of the IP8355EH is its 2-Megapixel resolution, which ensures clear, high-definition video captures. This clarity is essential for detailed monitoring, whether for security purposes or general surveillance. The camera utilizes a 1/2.7" progressive scan CMOS sensor, allowing for improved performance in low-light conditions, delivering quality images even in challenging lighting.

Built for resilience, the Vivotek IP8355EH boasts an IP66 weatherproof rating, making it suitable for outdoor usage where exposure to harsh weather elements is a concern. Additionally, it comes equipped with an IK10-rated vandal-proof housing, providing an added layer of protection against tampering or physical damage.

The camera features wide dynamic range (WDR) technology, which enhances visibility in high-contrast scenes. This capability is crucial in environments where backlighting may present challenges, enabling clear images of both bright and dark areas within a single frame.

With the Smart Stream II technology, the camera efficiently optimizes bandwidth usage without compromising image quality. This feature adjusts the image quality according to the monitored area and the level of detail needed, resulting in significant savings on storage capacity.

The IP8355EH is equipped with a built-in Infrared (IR) LED, providing night vision capabilities up to 30 meters. This allows continuous monitoring even in complete darkness, ensuring round-the-clock surveillance for enhanced security.

Networking capabilities are robust, with support for both Ethernet and Wi-Fi, enabling flexible installation options. Moreover, it supports Power over Ethernet (PoE), simplifying the deployment process by allowing power and data to be transmitted over a single cable.

Additionally, the camera is compliant with the ONVIF standard, ensuring compatibility with various video management systems. This interoperability is key for users seeking to integrate the IP8355EH into existing surveillance setups.

Overall, Vivotek's IP8355EH is a feature-rich, reliable outdoor IP camera that stands out in the competitive landscape of surveillance technology. Its combination of high-resolution imaging, durable design, low-light performance, and user-friendly features makes it an excellent choice for ensuring the safety and security of any environment.
