Teleste MPH241 - high performance IP HD/SD video encoder
Teleste MPH241 - high performance IP HD/SD video encoder

Standardised HD technology enables today cameras to provide higher resolution of video images than conventional SD CCTV – and transmitting HD video over IP is a key consideration in specific video surveillance applications. However, considering reliability, maintenance and security of typical IP cameras, it may not always be wise to extend your network to connect cameras “on the pole”. Why not use HD-SDI signalling for the first leg of your network and perform IP encoding in a safe location?  Teleste MPH241 is a compact, temperature-hardened and field-proven encoder that provides HD-SDI video input for further H.264 processing and networking. The encoder supports also standard SD video. MPH241 belongs to the Teleste MPH series that provides encoders for versatile network video encoding needs in both standalone and rack installations, and it meets the compliance requirements of EN50121 Railway standard as well as NEMA TS2 standard that is widely used for ITS applications. The MPH241 encoder delivers up to four independent video streams at full frame rate and full SD resolution using H.264, MPEG-4, MJPEG or MPEG-2, or any combination of these. Each of the individual streams can be optimised for separate purposes such as live viewing, recording, web applications and PDA. The MPH241 also ensures safe and seamless migration from any legacy hybrid video network towards fully H.264 based networks. For HD operations, the composite video input can be configured to a digital HD-SDI interface with full 1080p resolution. A synchronised audio stream can be attached to the video, and the video streams can be decoded by standards compliant media players and video decoder devices. The MPH241 offers excellent functionality that is not restricted to video operations. The encoder provides direct copper cable and fibre connectivity to Fast/Gigabit Ethernet networks through a built-in 4-port Ethernet switch. With SFP plug-in optics the encoder is suitable for a wide range of network topologies. The built-in EIA RS data channels provide multi-vendor PTZ camera control through Ethernet network. The encoder also includes alarm input and output that can be used to trigger events and control external devices. In addition to Command Line Interface (CLI) and comprehensive Web user interface, the MPH241 supports ONVIF specification and provides straightforward interoperability with any ONVIF compliant management system. Integration to third party systems can also be achieved using RTSP, SAP or SNMP. The MPH241 also offers low cost of ownership that is guaranteed by low power consumption and mechanical design that is made to guarantee high performance in harsh environments. DIN rail mounting is available through a set of accessories, and alternative powering methods support both local DC feed (10.5… 28 V) or PoE 802.3at.

H.264 video, audio and serial data encoder for IP/Ethernet networking systems MCC101/201 is an entry level single channel H.264/MJPEG IP video server with audio and PTZ data transmission capability. All settings and configurations are easily managed by an ergonomic web user interface. MCC101/201 provides a fluent unicast/multicast communication over LAN/WAN Ethernet networks. MCC101/201 is ONVIF/PSIA compatible and can operate as a part of a video management system. MCC101/201 has versatile video encoding parameters available, including resolution, frame rate and bit rate. For more technical requirements the unit has configurable settings for video profile type, de-interlacing, CBR/VBR rate control and I-frame interval. The video operation is supported with additional features such as information display overlay and burn-in OSD to the encoded video. For alarm and event activities the MCC101/201 series has a built-in video motion detection functionality and two sensor inputs (calendar synchronised). By using an event configurator all actions of interest creating an alarm can be forwarded either to email or to ftp address. A clip from the primary or secondary video stream, or a JPEG snapshot can be added as an attachment. In addition to video features the MCC101/201 series has two data ports for PTZ camera control and serial device communication. For audio operation there are two channels that can be switched to simplex or duplex modes. Audio coding can be selected between AAC or G.711 algorithms. For recording purposes the MCC101/201 series has a file transfer support for either FTP server or to external high capacity storage device (via an USB port). MCC101/201 is provided as a compact, small profile aluminium stand-alone housing. A wall mount is an option. Installation into a standard 19 inch rack can be also provided with an additional 1U high installation chassis having installation slots for two MCC101/201 units. MCC101/201 series units are suited for easy installations inside premises and other technical locations providing controlled environment. The nominal supply voltage for MCC101/201 series is 12 VDC and can be typically fed via a separate mains adapter. However as the MCC101/201 series is supporting PoE technology (Powered Device) the unit can be powered over the Ethernet network cabling as well.

Teleste CFO460 four channel video link provides low cost video transmission

CCTV and fibre optics – they are still dating Today a CCTV system does not necessarily need to be full IP yet. Much depends on the application, the scale of the video system or that the requirement is rather looking at a point-to-point transmission than spreading the signal into LAN or WAN network. The most critical specification requirement is naturally latency. For the vast number of analogue based CCTV cameras with composite video output still in use today, it is evident that the most efficient, maintenance- and trouble-free way of transmission is a basic fibre optic system. The same method is valid for HD video for which the transmitted content is a high bandwidth HD-SDI signal. The answer for deployments with high value on network safety and robustness against intrusion is a hybrid network solution. The so-called First Mile path from the CCTV camera to the nearest network node locating within “safe premises” can be carried out with a fibre optic link transmitting the signals in a secured and safe manner over a specific telecoms cabling or any dark fibre available. Such systems also have good scalability as there are available fibre modems that can multiplex and transmit various services simultaneously (video, audio, data, contact closure etc.). Multiplexing is also possible on the optical layer meaning that several modems can share the same fibre media. With very specific modems and passive backbone components the cabling topology can even be expanded from the typical point-to-point arrangement to support add-and-drop or redundant ring type operation – still only one fibre core is needed. The technology in these systems is based on standard CWDM lasers operating on different wavelengths. Should the application look at real time SD video operation the answer is modern fibre optic transmission. If the IP/Ethernet operation on the outer rim of the system is in control and approved, a modern fibre optic transmission system is an excellent choice for future system migration plans towards IP video. A specific fibre optic modem can support both analogue and digital IP cameras fluently by having the necessary interfaces to both worlds. Typically this is enabled by introducing a Fast Ethernet 10/100Base-TX interface available next to other interfaces reserved to analogue operation. In Teleste’s CFO fibre optic products, there is an implemented Ethernet support on the fibre modems that can be utilised for any type of IP based communication whether it´s video, LAN, industrial or VoIP related. The performance supports 100 Mbps operation in a Bridge Mode. Lately the CFO series fibre modems have also been harnessed with versatile SFP optical transceivers. In practise this means installation- and service-friendly approach by having a single modem model that can be equipped with the most suitable SFP transceiver depending e.g. on the cabling and distance requirement.
