High thermal sensitivity

Like many successful security technologies employed today, thermal imaging cameras had their foundation in the high-spec military arena. The successful adaptation of the technology for deployment in the business security sector harnessed the characteristics of infrared radiation from the human body as the base for the development of PIRs (passive infrared detectors).

The Samsung, Flir, and Bosch thermal camera product lines were developed to deliver reliable performance when there is just not enough light for traditional imaging. Sunell has entered this arena with a competitive offering, outstanding performance specifications and a robust mechanical build, as a desirable alternative in this established market.

Thermal security cameras are an ideal choice when monitoring environments such as heavily forested area and other areas that have obstructions that make viewing difficult. Wireless IP convergence company Miro’s latest Sunell IP thermal surveillance camera uses heat that is generated from an object or individual to detect their location.

In addition to detecting persons in the dark, thermal surveillance cameras are also good for capturing activity when outdoor conditions are less than ideal. Whether a blanket of heavy fog, or if conditions are compromised by the nature of your work, thermal cameras can still detect persons and objects through heat signature.

Thermal surveillance cameras can be the best option when you have difficult outdoor areas to monitor and want to further enhance the strength of your current IP camera system. “The images being delivered by thermal security cameras rely on heat that it is emitted from an individual or object. Thus, recorded video is strictly for detecting persons or objects in areas where they shouldn’t be. If you already have a low-light security camera in place, the addition of thermal surveillance cameras will significantly improve your security operation,” says Jan Keyser, head of products at Miro.

Sunell’s latest thermal bullet network camera, the SN-TPC4200K, includes features such as a non-refrigeration IRFPA sensor, infrared long-waves 8~14 μm, at 420×315 pixels, high thermal sensitivity up to 50 mK, with an 8/15/25/35/50 mm parfocal prime lens (optional), pseudo colour mode shift (black hot/white heat/iron red), and DVE image enhancement.

The Sunell thermal imaging cameras detect the infrared wavelength ranging from 8 m to 14 m and have a resolution of 420x315 pixels. The cameras are characterised by high thermal sensitivity of up to 50 mK and can optionally support a dedicated lens for 8/15/25/35/50 mm focal distance.

They support noise reduction and mirroring as well as four coding algorithms: H.264 BP, MP, HP, and MJPEG. The cameras output three code streams in real time, and satisfy the local storage and network transmission of the video. The three-axis rotational adjustment structure facilitates easy installation and adjustment.
