Fog, rain or smoke is no obstacle.

At the largest annual security event, IFSEC International 2012 in Birmingham, closed on May 17, Pelco, Inc. by Schneider Electric, demonstrated product dramatically expanding the capabilities of CCTV.

Thermal cameras of Sarix Thermal IP series from Pelco allow for detecting people, vehicles and other objects in total darkness, fog, smoke and rain. The main innovation is not the technology that is known and used for years, but the way of its integration with CCTV systems.
Sarix Thermal IP camera
Thermal imaging cameras, used mainly in armed forces and various industries, have their own standards of image capturing and recording, independent from those used in CCTV. ONVIF specification for modern IP CCTV cameras is currently being developed to ensure interoperability between products regardless of manufacturer. The more surprising is the fact that the Sarix Thermal IP camera is compliant with ONVIF 1.02 protocol.
Consequently, Sarix Thermal IP cameras can cooperate with typical NVRs. The built-in analytics includes motion detection, suspicious behavior recognition, object counting, detection of parking in prohibited areas etc.
At night, the cameras can detect a car from a distance of 1.9 km, a man from 800 m.

Due to new methods of mass production of sensors for thermal imaging cameras and the decrease in their prices, the technology will be a growing sector of the security industry. Faced with this technology, many ways of masking and misleading the current video surveillance systems will be ineffective.
Snapshots from this year's IFSEC security exhibition
IFSEC in Birmingham is the most prestigious exhibition event in the security market. This year it was attended by 750 exhibitors. The crisis on global markets and limited budgets of many companies resulted in more modest stands than they used to be in previous years.
This year the exhibitors presented a lot more IP and HD-SDI cameras, which is connected with the growing demand for high image quality in CCTV systems and new legal requirements for public video surveillance systems (e.g. for monitoring of mass events), where 4CIF resolution is found unacceptable.
Another area of ​​rapid development is image analysis. In addition to standard features like motion detection or counting and tracking objects, the systems are often equipped with procedures for interpretation of crowd behavior or quick comparison of human faces with photographs in existing databases.

Two-channel mobile DVR with GPS and vehicle speed recording.

Rising insurance premiums and fuel prices, dangerous driving situations and collisions which sometimes have to be examined in courts - all these factors prompt drivers of private cars and owners of transportation companies to install video monitoring systems in their vehicles. The optimal solution is the use of Protect 802 M70802.
Car DVR camera system: PROTECT 802 (2 channels, GPS, accelerometer)
DVR camera system PROTECT 802, 2 channels, GPS, accelerometer
Protect 802 M70802 is a mobile device (for indoor applications, typically inside vehicles) combining two cameras and DVR capable of recording high-resolution video (1280x480 from both cameras - side by side) and audio, plus GPS data and 3D accelerometer readings that can be displayed in the form of charts using three axes.
Wide viewing angles are ensured by 90° lens of the front camera and 120° lens of the rear camera. The images from the both cameras are merged into one picture with resolution of 1280x480 pixels, recorded at speed of 30 fps. This is an optimal solution for simultaneous monitoring of the interior of the vehicle and the road ahead of it. The video quality is sufficient for analyzing traffic incidents, behavior of people, and even recognizing people's faces or license plate numbers (of cause it depends on the distance of the objects from the front camera).
The video and data are recorded on Micro SDHC (Micro TF) card (supported capacity from 4 to 32 GB). 4 GB memory card can store about 65 minutes of recordings (two channels simultaneously). In the case of recording one channel, the time increases to about 140 minutes.
After moving the card to a reader on a PC platform (Windows/MAC), it provides dedicated player (JPlayer). After running the player, the user can play back the recorded video files, protect them against overwriting, read the speed values and GPS locations on Google maps (the PC has to be connected to the Internet), view graphs illustrating acceleration for each axis separately.

It's time for optical solutions.

Until recently, due to the high cost of FTTH system components for television distribution, long-distance transmission lines were based on thick and expensive coaxial cables and cascades of RF amplifiers. Today, it is neither modern nor cost-effective solution.
Currently, fiber optic networks often distribute TV signals directly to the end users, both in residential and other buildings.
Typically, the attenuation of optical fibers is 4000 times lower than that of high quality coaxial cables.

Example application of MOS-211A R81720 optical transmitter and Terra OD-003 R81728 optical nodes. This FTTH solution has been used in the plant of a consumer electronics manufacturer for testing DVB-T receivers.
The stands for long-term tests are spread over a distance of over 600 meters. Each node provides signals simultaneously to 15 receivers.
Optical Node TERRA OD-003 (FTTH receiver)
Optical node Terra OD-003 R81728 is ideal subscriber receiver for FTTH systems. The maximum RF output level of 80 dBuV is suitable for distribution of the channels via passive components throughout an apartment, office or one-family house.

How to properly install easy access cables?

ULTIMODE Building System is the latest solution for fiber optic cabling in buildings, which minimizes the number of optical splices. The basis of the cable system is provided by ULTIMODE BS cables with structure allowing for easy separation and distribution of individual fibers from the tube.

Easy access cable installation steps:
1. BS ULTIMODE cable should be
routed to the top story of the building (point A).
2. In order to connect a fiber to a subscriber's optical network unit in point D, it is necessary to cut out windows in the tube in points B and C; cut a selected fiber in point B and pull it out of the window in point C. The fiber is routed to the outlet in point D.
3. The windows in points B and C should be protected with appropriate shields.

Easy access cables:
  • L7712 - ULTIMODE BS-12SM (12 single-mode fibers)
  • L7724 - ULTIMODE BS-24SM (24 single-mode fibers)

Service monitor for CCTV installers.

After mounting a CCTV camera on the spot, the installer usually wants to make preliminary adjustments immediately, such as the focal length (field of view), focus, and other parameters available in OSD menu of the camera. MS-35P M3103 can be directly connected to the camera on the spot in order to monitor the image and all the changes. Thanks to a small size (3.5" screen diagonal), light weight and the possibility of wearing on the wrist, it can help the installer working even in an uncomfortable position such as standing on a high ladder.
The monitor can be powered from its built-in rechargeable battery or external AC/DC adapter. Another advantage is the ability to supply other devices operating at 12 VDC, with load up to 500 mA. This feature can be used when the camera is not powered yet from the CCTV system, but should be tested on the spot.

What kind of camera is best to promote towns on the internet?

The Municipal Council in Sandomierz, Poland, tests another camera showing the beauty of the town. This time it is a PTZ device operating in auto-patrol mode. The camera has been installed on the council building and provides video stream with resolution of 1280 x 720 pixels. Thanks to compliance with ONVIF standards, the stream can be easily archived on NUUO NVRs or other servers supporting that specification. The images from the camera, with the use of RTSP protocol and streaming server, have been placed on the town's website, together with the player.
