Introducing 4K vandal-proof IP dome camera WV-SFV781LH

Designed and manufactured in Panasonic Yamagata Plant, equipped with 6x optical zoom block camera, utilizing Lumix optical structure design from Leica, Panasonic WV-SFV781LH can not only deliver ultra high definition 4K images, but also provide ultra wide view angle, plus many top-notch features. It's a delicate dome camera, every single detail indicates the superb design capability of Panasonic. This security camera is suitable for use in airports, squares, lobbies, train stations, playgrounds, subways, tunnels and other needs of indoor and outdoor high-definition surveillance applications.

Let's begin exploring this cutting-edge 4K camera.

The camera's dimension is 228mmx189mm, the weight is approximate 3.2kg, the big size gives me the illusion that it's a PTZ camera.

This dome camera adopts aluminum housing painted with light grey color. Unscrew the screws on camera, then open the plastic dome cover, we can see its internal design. Moreover, Between plastic dome cover and camera, there is a black rubber ring to help camera withstand water ingress, dust.

The BIG size elliptical block camera is very eye-catching. It supports manually horizontal and vertical rotation to obtain ideal view angle for different video surveillance applications.

Panasonic WV-SFV781LH is a day/night surveillance camera, there are 18 pieces IR illuminators around the Stretchable lens.

This system supports temperature compensation function, through its internal fan and heater, the security camera can work in extreme high and low temperature condition. You can find a fan at the rear of camera, this fan can cool the system.

The on-board setting includes RAC video output, NTSC/PAL system switch, RESET button, SD card switch, SD card and Network working indicators, Auto Back Focus (ABF) button, Lens Tele/Wide (Zoom in/out).

While, this camera has simple connection interface, it has RJ45 connector which supports PoE, Audio I/O RCA connector, Alarm I/O connector, as well as DC 12V input jack. Please note that this dome camera can't be powered simultaneously by both PoE and DC 12V.

This dome camera adopts 1/1.7" progressive scan CMOS image sensor, its effective pixel up to 12.4 megapixel. Under the 3840×2160@30fps, 8192kbps video parameter, we measure the camera's resolution through test card. Its horizontal resolution is 1950TVL, vertical resolution is 2000TVL, edge resolution is over 1000TVL.

As we know this camera can provide ultra wide view angle, in aspect ratio 16:9 mode, it can achieve horizontal 17°(TELE) -96°(WIDE); vertical 9.3°(TELE) -54°(WIDE) wide viewing angle; meanwhile supports 6x optical zoom, 3x digital zoom, total up to 18x zoom capability.

In the same video parameter setting, we use the bit-rate test software to measure its video latency time. From several tests, we can conclude that its video latency is stable, controlled in the range of 500-620ms. The average video latency time is 550ms, and optimistic result is 500ms.

Similar to other Panasonic IP camera, WV-SFV781LH also supports many image enhanced technologies including wide dynamic range, 2D+3D digital noise reduction, as well as back light compensation (BLC). In the test, we put a doll inside the lamp, turn on the lamp to simulate strong light condition. After we turn on WDR function, the image get significantly improved. We can see much more detail on tester's face, as well as the doll inside the strong light lamp.

Aside from WDR, BLC function, the Panasonic WV-SFV781LH supports defog function. It has 1-128 level adjustable. After we turn on the defog function, the image becomes sharp, color and saturation enhanced.
