Beijing ## Chain Restaurant Monitoring Solution

Demand analysis

This monitoring solution belongs to network remote monitoring project. Above all install 2~3 channels cameras at each branch store by fixed and unfixed installation. Suppose that indoor sunlight is sufficient.
It is demanded transmitting branches video to control center to be managed.

Designment essential

This solution belongs to the remote monitoring of management field and its key point lies in selecting suitable DVR according to user’s demand:

• If branch store demands not to record or view local video, it is acceptable to upload video signal by DVS; all signals are transmitted to control center for unified management.
• If branch store demands to record or view local video, it is suitable to adopt DVR (digital video recorder) which enables local monitoring and upload video to control center for unified management.

More than that, the key part (especially total adoption of DVS) of system designment and establishing is how to ensure all monitoring signals normally transmission with finite bandwidth and numerous branch stores.
For the essential of resolving this key question, apart from advanced compression skill of reducing bandwidth, it is also necessary to design a scientific, reasonable and improved network, so as to save net resource and enhance usability. Therefore, it should adopt our big network monitoring solution------"IDRS NVMS"

Equipment selection

Fixed indoor camera is recommended adopting dome camera: ceiling mount, smart shape, hidden installation, reducing the disgust to monitoring devices greatly; integrating with camera, lens and dome’s housing, easy mount; charming cost performance. Due to rich sunlight, it has no demand for illumination of camera.
Moveable indoor camera is recommended adopting all-in-one color camera with pan/tilt and decoder. Compared with traditional cameras "box camera with motorized zoom lens", all-in-one camera has features: high integration density, built-in high-powered lens, wider viewing scope; auto iris, auto focusing, easier installation; smarter shape, suitable with common pan/tilt; adopt SONY movement, good quality, clear image, high saturation; super low illumination, suitable for poor light environment; easier installation, fewer maintenance frequency; more charming cost performance. By far all-in-one camera is the most popular in moveable camera series. The matched product is indoor dome’s pan/tilt of features: dome shell, built-in pan/tilt, ceiling mount; hidden visual effect, high sense of wholeness. Price is higher a bit than common pan/tilt.
Main control device adopts IDRS-6000S-HC series real-time DVR (especially high-end configuration) of features: H.264 compression format (top advanced worldwide), save more space; audio and video sync record, clear picture and sound; real-time video display & record speed; full functions, strong expansion ability (direct expand to 24 real-time channels); strong network remote monitoring, occupy less bandwidth; system window more friendly, easy set, high stability; multiple languages satisfy various users. Functions: real-time view monitored area, store video; control camera & lens and network transmit. All specifications gain Public Security Ministry’s authentication.
Main control devices can be matched with IDRS404C DVS of 4 channels of features: advanced H.264 compression algorithm, lower compressed code stream, faster network transmission, higher image quality; embedded real-time multitask operation system (RTOS) and embedded processor, integrate audio/video capture, real-time compression, net transmission, PTZ control, video storage, linkage alarm and bidirectional voice talk; support RTP/RTCP, RTSP stream protocols, IE browse; smart size, easy installation, plug and play, suitable for scattered and networking transmitted surveillance projects, compared with DVR:

• Performance: They have same monitoring functions. But NVS without HDD and fails to save data locally, accordingly, it converts video signal into digits to network so as to be viewed by net clients; on the contrary, DVR adopts HDD storage locally, due to local viewing not affected by bandwidth, local video is real-time. Meanwhile, DVR supports network functions of NVS, able to upload all monitoring signals to network for remote visit and monitoring, besides, local client operation separates with remote client, standalone each other.
• Usage: due to NVS small size and most as singe channel or 4 channels, it fits scattered monitoring environments (i.e. among different regions or nations) which has finite amount and hard to set up control center locally. However DVR is mainly used when local cameras are excessive and demanding set up control center to fully real-time record & save, meantime needs remote network monitoring.
• Management: DVR supports picture browse, PTZ control and video record, but it needs place at specific room with definite person’s protection, which costs much cost. Thus for small size branch stores, adopting NVS is more suitable for them.
• Price: so far NVS has mature models of single and 4 channels, but DVR has 4, 8, 12 and 16 and 24 channels. Therefore, it is more economical for multi-camera company or store to select one DVR than select multiple NVS.

Needing to be pointed out is that network transmission is different with coaxial transmission and transmission effect is usually affected by network stability and bandwidth. So in order to get ideal effect of transmission, besides adopting good transmission device, we must try to select better network condition, by this way, stable and fast transmission will come true.

Such a selection is based on the precondition of ensuring stability and demand, separately choosing economical or high-end product according to price range differences. Users would select definite product according to real cases (Suggested: try to adopt higher performance product in order to enhance monitoring effect and security degree).
