HD camera family

by Mark Rowe

Bosch Security Systems now offers the MIC family of ruggedised pan-tilt-zoom cameras. The new MIC IP starlight 7000 HD camera delivers HD video images in extreme low light situations and captures moving objects in 720p HD resolution at up to 60 frames per second. It delivers video images where others fail, even down to 0.01 lux. HD images are captured in colour down to 0.05 lux – when others switch to monochrome – to reveal colour details. The new MIC IP 7000 HD family withstand a range of harsh conditions – from minus 60 to 60 degrees Celsius with up to 100 percent humidity, as well as rain and snow, high wind gusts and vibration.

The MIC IP dynamic 7000 HD offers 1080p resolution and captures multiple exposures of the same scene to provide detail in areas with both bright and dark lighting conditions. The wide dynamic range and intelligent backlight compensation are so that moving objects or specific objects of interest are enhanced and can be identified in scenes with simultaneously bright and dark areas, which typically challenge standard cameras.

Both cameras also feature intelligent de-fog to dynamically adjust camera contrast settings where scenes are affected by fog, smog, mist or other low contrast scenes.

Detection of objects of interest in complete darkness is ensured by the optional MIC illuminators. These illuminators consist of both IR and white light LEDs, and operators can switch between the two light sources at a click. This enables detection of objects up to a distance of 175 meters, it’s claimed.

Another differentiating feature of the MIC IP 7000 HD family is built-in Intelligent Video Analysis (IVA). It helps to focus on relevant situations by alerting you when needed, or automatically tracking objects of interest. IVA also adds sense and structure to video data by adding metadata already in the camera. This allows retrieval of the relevant images from stored video. Metadata can also be used to deliver forensic evidence or to aid business processes based on, for example, people counting or crowd density information. A user can simultaneously combine eight of the 15 available IVA rules, to combat false alarms.

Among other uses, IVA can assist in monitoring unmanned stations or pipelines where people are not expected during normal operations, and since security guards cannot be everywhere, or watch everything at the same time, IVA alerts can also be sent to mobile devices when needed.

Intelligent Tracking (iTracking) automatically tracks moving objects based on pre-defined alarm rules or a simple click. By distinguishing between single and multiple reference points, iTracking will provide uninterrupted tracking. Optimal capture of the object of interest is assured by dynamically adjusting the field of view, so the user never loses track of objects of interest.

Limited bandwidth makes it impossible to stream HD video on mobile devices whereas Dynamic Transcoding delivers live video streaming and access to HD (1080p) images when needed, regardless of available bandwidth, according to the makers. With the Video Security app, users can access camera controls, live video streams and HD images via a mobile device. It also enables you to retrieve the correct video data from recorded material. The new MIC IP 7000 HD family is fully supported by Dynamic Transcoding with either one of the Bosch DIVAR IP recording solutions or a Bosch VIDEOJET transcoder.

To reduce storage costs and network strain the new cameras feature intelligent Dynamic Noise Reduction (iDNR). This leads to bandwidth only being used when needed. When there is little or no movement in the scene, less bitrates is required. Therefore, iDNR actively analyses the scene distinguishing between relevant information such as moving objects and image noise artefacts. The degree of noise reduction is adjusted accordingly so that important objects are captured and image noise artefacts suppressed, optimising the camera’s bitrates. Thus, iDNR saves up to half it’s claimed on bitrates and hence storage and network strain without the makers say compromising video quality. Local storage on the camera compensates for short network outages, so that video data is available in VRM systems without breaks.

Using the VIDEOJET connect 7000 with MIC and other Bosch IP cameras provides Power over Ethernet support and flexibility in network configuration and remote video access. Its built-in network switch supports connections to multiple IP cameras, for installations along perimeters or roads. Live video streaming and instant access to HD (1080p) images within limited bandwidth connections and control of HD video images is through its built-in transcoder which supports the Dynamic Transcoding.

Bosch IP standard-definition and high-definition cameras, encoders and analytics work with security software and recording solutions from Bosch and other industry providers. This is backed by ONVIF conformance (Open Network Video Interface Forum) and the Integration Partner Program (IPP), which gives developers access to software development tools to integrate Bosch products with third-party systems.
