Application and Service

  • Baud Rate: The baud rate is associated with many mathematical formulas. Its units are either symbols per second or pulses per second. Baud can be determined by using the following formula: Baud = (Gross Bit Rate / Number of Bits per Symbol). This can be used to translate baud into a bit rate using the following formula: Bit Rate = (Bits per Symbol * Symbol Rate). Baud can be abbreviated using the shortened form “Bd” when being used for technical purposes. Setting for PTZ, Baud rate/ Camera address/Protocol on camera must be the same as on the DVR in order to make the PTZ from the DVR.
  • Code: Coding can be divided into CBR(Constants Bit Rate) and VBR (Variable Bit Rate)
  • Dual-Stream: Main stream, sub stream
  • DHCP: Dynamic Host Configuration Protocol
  • DNS: Domain Name System
  • DDNS: Dynamic DNS
  • FPS: Frame per second
  • GB/TB: Refers to the hard drive size. Gigabyte/ Terabyte, 1000GB=1TB.
  • Master-Stream: Main stream, local transport stream high definition video can achieve higher storage. Same FPS and resolution at live view and DVR (ex: D1 at 30 fps), required more bandwidth.
  • Max Bit rate: 64kbps, 128kbps, 256kbps, 512kbps, 768kbps, 1Mbps, and 2Mbps according to the different DVR options
  • POE: Power Over Ethernet POE
  • POP3: Post Office Protocol 3
  • Quality: Quality client-side image-quality, picture quality is higher, clearer image, select range lowest, lower, low, medium, higher and highest
  • Resolution:
    • CIF: 352 ×240@NTSC 352 × 288@PAL
    • D1: 720 × 486@NTSC 720 × 576@PAL
  • ·         SMTP: Simple Mail transfer Protocol, is an Internet standard for electronic mail (e-mail) transmission.
  • ·         Sub-Stream: Sub streams, remote transmission in the lower stream to accommodate various networks such as CDMA/ADSL and obtain higher image smoothness. Sub stream is good for networks with slow upload speeds, all the cameras are on sun stream by default when you access it remotely.
  • ·         Three Stream: Three streams (main stream, stream, ultra-low stream)
  • ·         Ultra low stream: Ultra low bit-stream is used for 3G network

 

DVR Vocabulary

 

  • ADSL: Asymmetric Digital Subscriber Line
  • CMS: Central Management system, the software on the CD that ships with our DVR is this program, allowing multiple DVRs and up to 1000 cameras to be view at the same time.
  • DDNS: Dynamic Domain Name Server
  • Dual core: Refers to the processor in the motherboard of the DVR, will be able to format hard drive
  • FTP: File Transfer Protocol
  • H.264: Is a new video codec standard which can achieve high quality video in relatively low bitrates. You can think it as the “successor” of the existing formats (MPEG2, MPEG-4, DivX, XviD, etc.) as it aims in offering similar video quality in half the size of the formats mentioned before. The codec process include five components:
    • Inter and intra prediction (Estimation)
    • Conversion (Transform) and inverse transform
    • Quantization (Quantization)
    • Trans quantified loop filter (Loop Filter)
    • Entropy coding (Entropy Coding).
  • HTTP: Hyper Text transfer protocol
  • PPPOE: Point-to-point protocol over Ethernet, ) is a specification for connecting multiple computer users on an Ethernet local area network to a remote site through common customer premises equipment, which is the telephone company’s term for a modem and similar devices.

 

Static IP/Dynamic IP: As the name implies Static IP addresses are the same every time you connect or send a message. Static IP Addresses are used by all major web sites, email services, FTP services and so on. There are no exceptions to this. You will pay handsomely for static IP addresses. Dynamic IP addresses may change each time you connect to the Internet or even, in extreme cases, every time you send a message. Dynamic IP addresses are the normal customer access method used by most ISPs or Service Providers.

  • UPNP: Universal Plug and Play, Universal Plug and Play (UPnP) is a standard that uses Internet and Web protocol s to enable devices such as PCs, peripherals, intelligent appliances, and wireless devices to be plugged into a network and automatically know about each other. With UPnP, when a user plugs a device into the network, the device will configure itself, acquire a TCP/IP address, and use a discovery protocol based on the Internet’s Hypertext Transfer Protocol (HTTP) to announce its presence on the network to other devices.
  • Interface
  • Alarm in (Sensor in): Alarm input, two lines no distinction between positive and negative pole connection normally open (NO-normal open) or closed (NC-normal close), usually by jumpers or software settings, sometimes require an external resistor, and resolved through serial or parallel probes of the normally open and normally closed compatible.
  • Alarm out (Relay output): Alarm output, is usually normally open (NO) settings
  • Audio in: Audio input connections pickups, generally uses RCA connectors
  • Audio out: Audio output, connect speakers or the monitor’s Audio in
  • BNC: Bayonet Nut Connector is a tool for coaxial cable connector, full name is the Bayonet Nut Connector (bayonet nut connector), BNC connectors can be isolated from video input signal, signal interference between, and signal bandwidth than a normal 15-pin d-type connector, and can achieve better signal response results.
  • CVBS: Composite Video Broadcast, composite video broadcast signal to baseband video or RCA video (BNC line transmission is the CVBS signal)
  • Compact Case: Compact chassis
  • ESATA: Extended serial hard drive interface, full name is the External Serial ATA (external serial ATA), which is SATA SATA interface for external extensions → eSATA/USB large hard drive directly to an external specification. In other words, eSATA is the “external” version of the SATA, which is used to connect to external rather than internal SATA devices. For example with eSATA interface, you can easily move the SATA hard drive with eSATA interface connection Board, replace the SATA hard drive without opening the chassis. Generally used for backup interface or disk array interface;
  • GND: Grounding port (public)
  • HDMI: High Definition Multimedia Interface is a digital audio/video interface technology. For the HD digital signal interface, used to close HD digital signal transmission. Image to display using the HDMI interface is clear, smooth, minimal delay

  • RS485: Used to control the front of PTZ devices such as speed dome
  • SATA: Serial Advanced Technology Attachment (serial advanced technology attachment, a serial based on industry-standard hard drive interface), is determined by Intel, IBM, Dell, APT, Maxtor and Seagate company jointly made hard drive interface specifications. In 2001, consists of Intel, APT, Dell, IBM, Seagate, Maxtor which consists of several major manufacturers of Serial ATA Committee formally established the Serial ATA 1.0
  • SDI: Serial Digital Interface A data channel that transfers digital data in a serial fashion: one bit after the other over one wire or fiber. Serial interfaces may have multiple lines, but only one line is used for data. The other lines are used for control. SDI digital output interface data rates, long-distance, cabling and the construction of traditional analog lines the same, basic rate reached 270Mbps.
