Panasonic WV-SPV781L 4K Camera

4K network vandal-resistant IR security camera WV-SPV781L

The resolution of 4K network camera is 27 times higher than VGA resolution of conventional analog camera. It's 9 times higher than high definition (1280x720) resolution, and 4 times higher than full HD resolution (1920x1080). Panasonic ultra HD 4K security cameras utilize Panasonic patent 3-layers driving lens system to achieve astonishing 100°field of view zoom lens with 6x optical zoom. This unique design enable camera to truly output ultra HD images. Additionally, it has automatic rain cleaning and defrost function, it is able to provide reliable video surveillance despite the extreme weather conditions.

4K surveillance is developing rapidly, since the improvement of surveillance technology, HD becomes the main trend in today's video surveillance industry, combines the latest network technology, it not only meet the increasing HD demand, but also offers offers versatile features. In this article, we intend to introduce you the WV-SPV781L from Panasonic, this camera is the latest design network camera adopts "True 4K technology", equipped with patent 3-layers optical lens driving system consists of 2 zoom lens groups and 1 focus lens group.

Panasonic WV-SPV781L is a robust look, but compact size camera, its dimension is 133mmx420mm. The camera's housing is durable aluminium metal, you can find Panasonic logo and product model, as well as 4K logo on camera housing. This camera is suitable for indoor and outdoor video surveillance , it features vandal-resistant and IP66 rated weatherproof, included with automatic rain cleaning cover.

This network camera utilizes Panasonic 1/1.7" progressive scan MOS image sensor which delivers 12.4 megapixel effective resolution. In 12.0 megapixel (4:3 aspect ratio)@15fps, under lowest optical zoom, the security camera still can recognize hundreds meter away objects. According to manufacturer provided testing data, this network camera can deliver 2500TVL ultra HD resolution in 12MP format. In addition to accurate color reproduction, this network camera's recognizable grayscale level can reach up to 19 grade.

This network camera adopts Panasonic newly developed 3-layers lens driving system. In 16:9 aspect ratio can achieve horizontal 17°(tele) ~97°(wide), vertical 9.4°(tele)~55°(wide) ultra wide viewing angle; furthermore, the lens supports 6x optical zoom, 3x digital zoom, total 18x zoom, in 6x optical zoom, the 2km remote objects clearly present on video, while image color keeps bright and vivid.

The camera can provide smooth video when it set to 8MP@30fps, 8182 kbps video parameter. The camera aims at outdoor scene, using the bitrate calculating software, we can test its video stream bitrate is controlled in the range of 7.9-8.0Mbps. Through 10 times video latency calculation, we find that its average video delay time is in the range of 439-494ms, bitrate control and video latency performance is quite impressive.

Then, let's test its performance when WV-SPV781L works in different light conditions. After enable the WDR function, the image's background becomes bright; if enable the BLC, background brightness significant improves; enable the HLC, the doll inside the strong light shade becomes clear. Moreover, this camera supports digital defog function. In real test, the image becomes clear after enable the defog function.

In aperture F1.6 auto control mode, we put the camera into dark box. After measurement, we find that the camera will automatically switch to B/W mode when illumination is 1.3Lux. In B/W mode, the image keeps clean, meanwhile we find that its low illumination is 0.00 Lux (real value is 0.001-0.009Lux), low color illumination requirement is 0.35Lux, its low illumination reaches star-light level.

"0.00Lux" Low illumination

When illumination is 0.75Lux, the built-in smart LED illuminators will automatically turn on, quick and high sensitivity, these infra-red illuminators enable camera to capture images even under complete darkness environment. In this camera auto-switch setting, it has additional auto-switch (Infra-red) and auto-switch super color compensation (SCC) function. After switch to Infra-red mode, image keeps clean, to SCC mode, image's color has effectively improved.
