TD-8843IM (WP/37M/VL50)

4MP 37x 500m Laser AI Network Speed Dome

TVT 8843IM adpots 1/1.8" progressive scan CMOS chip. With the powerful 37x optical zoom lens and accurate pan/tilt/zoom performance, the camera provides a wide monitoring range and more details. The camera delivers 4MP ultra high definition resolution at 50/60fps. With the smooth control, high quality image and good protection, it targets high-end video surveillance applications, such as rivers, forests, roasd, railways, airports, squares, parks, scenic spots, stations and large venues, etc.

Artificial Intelligent

Integrated with 2.0 Tops CNN deep-learning Engine and powerful CV and video DSP, this products can switch among four scenarios-face  recognition(FR), license plate recognition(LPR), (human and vehicle)mixture lanes detection mode.

Up to 30 targets can be detected simultaneously. Additionally, the PTZ support human/car recognition and real-time auto zoom tracing.

Superior Image Quality

The product adopts high MTF 37x zoom lens and 1/1.8" back-illuminated Near-IR enhanced image sensor, and 3rd generation of image signal processor, so the better image quality could be achieved. In most night scenarios, a vivid color image is output without switching to W/B mode. Most street lamp and car’s lamp smear could be suppressed for its high dynamic range.

Optical Defogging Lens

Generally, visible light could pass through raindrops, haze and fog in the air only in a short range. Within the built-in defogging lens filter, the camera can switch to 900nm-1150nm mid-wave infrared imaging on a foggy/rainy day. As MWIR light from the target has more chance to pass through the raindrops, fog and haze in the air, the visibility of the camera is twice as far as normal cameras.

Sync-Zoomed VCSEL Laser Illuminator

The product adopts a sync-optical zoomed VCSEL (vertical-cavity-surface-emitting) laser illuminator. The VCSEL has more efficient and longer life than traditional  laser light source. The laser lens zooms synchronously with the image lens, so the IR(W/B) image effect could be more even and no breaking in camera’s zoom actions.Even on a moonless night, the camera could still distinguish human face 400m (LP 500m) far away.

H.265 Encoding

The H.265 (ITU-T VCEG) video compression standard offers double the data compression ratio at the same level of video quality, and substantially improves video quality at the same bit rate, compared to older video compression technologies.

Smart Thermal Management 1.0

The camera has built-in temperature sensor, high-efficient turbofan, as well as high power heater. The real-time temperature detection and control algorithm make the camera work well in a wide temperature range from -50°C to 65°C(-58°F~149°F) . It also supports cold start temperature above -40°C(-40°F), so it is suitable for extremely cold areas like Russia, Canada, Sweden, etc.

Working Environment and Interoperability

Subjected to rigorous dust and water immersion tests and certified to the IP67 Ingress Protection rating and Ik10 impact test. This product allows for 6KV lightning rating, which provides effective protection against lightning. Therefore, this product could work well in high concentration of salt and alkali corrosive atmosphere, such as Inland-sea countries, desert areas and so on.

The camera conforms to the ONVIF specifications and Chinese GB/T28181, ensuring interoperability between network video products regardless of manufacturer.
