Hanwha Techwin has further strengthened its keenly priced Wisenet Q series with the introduction of four new PTZ cameras.

The new indoor and outdoor 2-megapixel PTZs are equipped with a host of innovative, practical features including Focus Save function, which can be applied to 32 pre-defined areas and ensures that the cameras are able to rapidly come into focus when they are moved to a specific position.

Precise PTZ control is achievable with the assistance of ‘click & drag’ which enables operators to use a mouse to rapidly move the camera to a new position and ‘click to centre’ which focuses the cameras on a specific area of interest within a field of view. A scroll wheel zoom feature also allows operators to quickly zoom in to see close up activity of any suspicious activity or incident.

In addition, up to 12 customised direction indicators, such as ‘to the car park’ or ‘main exit’, can be superimposed over a field of view to help operators, who may not be familiar with the location they are monitoring, decide where to point the cameras.

The outdoor models have enhanced protection from rain and snow. This is because, unlike conventional PTZ cameras which can require up to 5 separate cables, they only need a single RJ45 cable to operate. In addition to minimising the possibility of water damage, this also makes them quick and easy to install, as does a ‘match 3 points and twist’ installation feature.

Other key features include the following:

The ability to ‘hand-over’ to cameras covering adjacent areas, means operators can continue to observe people or vehicles as they move out of the PTZ’s field of view.

Digital Image Stabilisation (DIS) with built-in Gyro sensors which comes into effect when a camera is disturbed by wind or vibrations. This delivers more stable images, whilst also compensating for roller shutter effects.

A Micro SD slot allows video or data to be stored at the edge should there be disruption to the network. Up to 256GB of video which might have been potentially lost, can be retrieved when the network connection is restored.
Power over Ethernet (PoE+) which negates the need to install a power supply and separate cabling for the camera.
When connected to one of the new PTZs, an optional Wisenet SPM-4210 Network I/O box provides the choice of 4 alarm inputs/outputs or 1 audio port and 2 alarm inputs/outputs.

The new cameras are as follows:

QNP-6320: 32 x zoom indoor PTZ
QNP-6250: 25 x zoom indoor PTZ
QNP-6320H: 32 x zoom outdoor PTZ
QNP-6250H: 25 x zoom outdoor PTZ

In addition to these just launched PTZs, Hanwha Techwin has announced that it also intends to introduce 2 further Wisenet Q series PTZs at a later time. Both of these will have built-in IR LEDs which will illuminate objects located up to 100metres from the cameras.
