Bosch IP An introduction to IP technologyand the future of CCTVBosch IP Network Video Product Guide

2 3Changes in CCTV technology have been driven by three main requirements.The first is the need to reduce the cost of recording and storing video for longperiods. The second is the need to reduce the amount of space required by thesesystems. And the third is the need for improved accessibility.IP Network Video –the next generation of CCTVGreat leaps in technology are made onesmall step at a time. Bosch IP NetworkVideo takes you step by step into thefuture of CCTV.VCRs were the first – and for many years, only –CCTV option. Affordable and reliable, VCRs arealso labor-intensive, requiring someone to switchtapes, clean recording heads and performscheduled maintenance. And the thousands ofvideotapes generated not only caused storageproblems, but were a security risk as well.Anyone could view or alter them, and therewas no existing backup.Network video recorders (NVRs) using IP NetworkVideo are the third generation – the next step inthis evolution of more cost-effective and spaceefficientsolutions for viewing and storing video.IP-based digital encoders push encoded videoonto the network for storage anywhere. This hasopened the door to the process of convertinganalog video to digital, storing it in one place,and viewing it from anywhere in the world.Digital video recorders (DVRs) revolutionizedthe industry by eliminating bulky videotapesand placing archives of video at your fingertips.No more costly maintenance or tedious tapeswitching. Searching became instant and reliable.And while DVRs still require a switcher to funnelvideo into the operations station, as technologyimproves, so do video size and storage devices.As with any technology advancement, some userswill be ready to make the jump to IP immediately,while others will prefer to transition over time.Because Bosch IP Network Video products arecompatible with existing analog components, thetransition can be effected gradually, allowing youto take advantage of the benefits of IP video whilecontinuing to make profitable use of your analoginvestment. Or, you have the option of installinga complete IP system all at once for instantaccess to the latest CCTV technology.

4IP Network Video systems offer a number of advantages over traditional analogsystems. Convenience, cost effectiveness and overall efficiency of the CCTVsystem all play a part in the decision to make the change to IP.The advantages of IP Network VideoWith IP, a single operator can monitor remoteand wireless cameras anywhere on the network.AccessibilityAs the market strives to reduce the amount of staffneeded to operate security systems, IP networksallow further centralization. A single operatorcan monitor remote and wireless cameras fromanywhere on the network, and the video canbe stored remotely as well. And while manycompe titors offer point-to-point wireless capability,Bosch allows wireless access anywhereon the network.Simplified installation at lower costsRather than requiring extensive coax cablinglike analog systems, IP Network Video systemsconnect through CAT-5 or wireless communicationsystems that already exist in many buildings.Reduced storage costsWhen CCTV video moves into the networkedworld, it allows you to take advantage of ITtechnologies like network attached storage andstorage area networks, which can hold hugeamounts of data. The system is using dedicatedhigh-density storage servers rather than relyingon a single hard drive. The video on those serverscan then be shared with anyone anywhere onthe network.ReliabilityIP uses the benefits of Internet technology tocreate a more reliable security system. It canautomatically redirect video traffic to a backupstorage system in the event of a power failureor network outage.ScalabilityIP networks offer improved flexibility for enlarginga CCTV system. It is not only easy to add cameras,but also to add storage space and distribute itacross the network. Plus, IP networks are uniquelyable to support multiple viewers. In the same waythat an e-mail server can send the same data tomultiple people at the same time, the networkswitch has the ability to clone the video and usethe same data multiple times.Video qualityModern IP systems use MPEG-4, which makesmore efficient use of the network than M-JPEG.For times when lower quality would be sufficientand would help control the amount of storageused, IP gives you the ability to customize thequality of the video output based on your viewingneeds and storage capacity.M-JPEGMPEG-4IP Network Video systems using MPEG-4 deliverhigher-quality video than M-JPEG for the sameamount of bandwidth.

6 7Bosch can help you make a smooth, efficient transition from your current system to IP capability.We now offer a complete line of IP Network Video products for video and audio streaming,recording, playback and archiving. Our IP Network Video products are unique because we offer theoption of having storage within the encoder devices. This capability bridges the gap between DVRsand IP video, as well as offering other specific advantages.Bosch VIDOS Video ManagementSystem allows you to switch camerason your PC monitor or bank ofanalog monitors.Reliable CCTV – even through network failuresOnly Bosch can offer you the reliability of itspatent-pending Automatic Network Replenishment(ANR) technology. ANR allows local storage in theencoder to act as backup if the network goes down.Conventional NVRs experience recording gaps duringnetwork failures, but Bosch’s NVR uses ANR toautomatically replenish those gaps. It even staggersthe information relay to the NVR so the networkdoesn’t get overloaded.Trust Bosch for your IP Network Video solutionBosch’s patented ANR technologyensures uninterrupted surveillanceand recording, even through networkfailures.Audio capability – listen inOptions are available with one- or two-way audio.Bosch enables video and audio to be relayed as asingle media stream so the two are synchronized.Pre-alarm recording – capture the lead-upto major eventsBosch encoders can temporarily record video of keysecurity locations; then, if and when an alarm isactivated, they will rewind and permanently recordthe information just before and just after thealarm. The relevant video is safely stored on thesecure server, but valuable space isn’t wastedwith hours of uneventful recording.Video management systems – bridging PCand analog viewingBosch encoders can temporarily record video Thebest CCTV systems enable users to view video viaboth PC and analog monitors.

8 9The ideal IP Network Video system would offer the highest quality video and audio sent fromcameras located at every conceivable point, viewable from anywhere in the world with an unlimitedamount of long-term storage. The reality is that every system is limited by two finite resources:network bandwidth and disk storage. Bosch’s goal in developing IP Network Video solutions is touse these limited resources to maximum advantage, giving you the most cost-effective andspace-efficient CCTV system possible. Some key benefits of Bosch IP Network Video productshelp achieve this goal.The most efficient security systems are those in which all aspects can communicate. But to do this,they need to speak the same language. IP technology is this common language. With an IP-basedsystem, customers can mix and match best-of-breed solutions for intrusion and access systems aswell as CCTV cameras – all of which are making the transition to IP. In the near future, securityproducts will communicate predominantly through IP. But until then, Bosch is helping you make thetransition by leveraging this new technology rather than embedding it in every product at once.Bosch toolsfor better resourcemanagementBuilt-in motion detectionMotion detection through an IP encoder is typicallyused to raise an alarm to the operator, increasethe frame rate of the recording to capture theevent in more detail, and cause the alarm video tobe safely stored either locally or on a distant NVR.The impact of IPon security technologyRelaysCentral monitoring sites simply can’t afford tohave dedicated wires running to and from everylocation and device that needs to be controlled.IP technology allows the operator to switchanything on and off and control it from anywhereBosch motion detection is even more sophisticated,in the world.allowing you to designate the specific directionVideo and audio compressionThe evolution of compression formats is an unendingprocess – from MPEG-1 on S-VHS to MPEG-2for DVD, then MPEG-4 for Internet streaming. Boschvideo IP encoders are field upgradeable, so if abetter compression format is discovered, you haveaccess without investing in new hardware. Ourcurrent technology relies on MPEG-2 and MPEG-4rather than MJPEG to achieve better efficiency.Specifically, MPEG-4 stores only designatedkeyframes and then the difference betweenof motion that would trigger the alarm as well ashow much motion needs to happen. The result isthat as little information as possible is sent acrossthe network and stored when nothing is happening,but as soon as an event occurs, it is captured ingreat detail.MulticastingIP network technology enables the network switchto automatically clone data if multiple recipientswant to view the same thing. The proper switchAudioLike Internet radio, IP allows the transmissionof audio over enormous distances. And becauseit’s digital, not analog, the sound quality doesn’tdegrade over long distances. Once archived,it can be played back over and over withoutdegradation. Most importantly, there’s no needto run separate microphone or speaker wiresfrom the camera to the observer. It’s all doneover the ethernet.Serial portsThe average serial cable becomes unreliable afterthe first 3 to 4 meters. But by converting the serialdata to IP, the same data can be moved across theplanet and in both directions. In CCTV applications,this is particularly important to the reliableoperation of PTZ cameras over long distances.WirelessAdvances in wireless technologies have beenfueled by the demand for increased mobility andsubsequent frames. So if the view of a hallwayremains unchanged for hours, the scene and anychanges in it are captured using a minimum ofstorage. And the number of keyframes is fullyconfigurable according to specific user needs.Dual streamingBosch encoders offer dual streaming capability.Depending on the model chosen, users can adjustallows multiple viewers to see the same cameraover an LAN or WAN without stressing the singleencoder. This is a vital component to a scalablesolution.Bandwidth throttlingEven dedicated CCTV networks can get crowdedperiodically. With Bosch, users can choose how toadjust to accommodate temporary traffic surges.Sophisticated built-inmotion detectionallows the user to setparameters to maximizeboth surveillancecapability and networkefficiency.AlarmsAlarm triggers can be generated by an amazingrange of products, including contacts, sensorsand other systems. But now, instead of beingtranslated from voltage across two wires, theyhave become bits of information that can bereceived and handled anywhere on the network– even by multiple recipients.ease of installation. IP enabled products instantlyleverage this trend without requiring any changein their technology. Where is this technologyheaded? Imagine walking around with a singlewireless tablet and viewing any camera on yournetwork. Or instantly installing cameras alongtunnels and bridges without any cabling exceptpower.
