Some basic Tips to Improvise Your Surveillance System
( CCTV Operator & Customers Perspective )
There blog is being intended for CCTV Operators and clients who have a large responsiblity to protect their premises , saving lives and detecting thefts via Surveillance Systems . Here we are discussing about some very important checklist points that a system designer should follow to reap all the benefits of a good surveillance system and thus qualifies for being all the important checklist points for an operator . Also these tips will be helpful for you to improvise , understand and plan your Surveillance System . Since here we will be talking from End User perspective we will not be going into deep for the technicals and will be trying to make it very simple to fulfill your perspective .
Make sure you are using UPS powers to power your survelliance Servers / NVR / DVR / Network Switches !!
you should use UPS power sources to power all your survelliance servers and Networking Switches which are providing network infrastructure for your CCTVs to your storage and survelliance servers . These equipments uses semiconductors and diodes for their image processing and thus any power fluctuations can damage these equipments .
If Night Vision IR sensors are there in the cameras installed at your premises at Low Light areas , Outdoor Cameras and strategic Locations !!
Yes , please check with your system integrators that the cameras they have installed for you have night vision sensors in them or not . A perfect lighting conditions and 24 hours lighting cann't be guaranteed at all the strategic places and Outdoor areas . The shop owners / Jewellery stores should specially go for all IR Cameras inside their premises . The residence and vills owners should check these cameras availability at their entrances , exits and perimeter protection areas . Even if the system integrator ensures night vision cameras at these place they should know the range ( Distance that a camera can view in night Vision Mode ) so that you know what will cover and what will not . The night vision cameras with 20 - 30 metres of range are easily available in the market . There are some peripheral protection cameras that can even view upto 150 metres and higher during night .
If SD Card Support is present inside your cameras present at strategic places !!
Yes often what happens that strong winds , storms ,rain and other civil activities breaks down the link between your Video Surveillance Servers /NVR/DVR especially at locations such as main entrances , exits and parking areas of your prmises , shops or stores and in that case you may loose important surveillance feeds however this can avoided if your CCTV supports SD Card storages for temporary feeds and immediately sends the feed to your surveillance server / NVR / DVR after the establishment of the link .
The resolution is adequate for the cameras at your strategic places !!
Yes ofcourse !! The better the resolution the more clear the picture will be . General perspective cameras can use 720 P images but face can not be detected at 720 P . Similarly you can recognise a person at 1080 P or 1200 P but can't recognise a number plate of a car . A detail planning and analyses will be required for the cameras to be used at your locations and for what application .
The WDR and HLC is present inside your camera at high light areas or outdoor cameras !!
Sometimes at strong light areas the image obtained are not clear or have white patches of sun rays . A Wide Dynamic Range WDR Cameras and High Light Compensation Cameras have inbuilt features to compensate light differences at such areas . One should use WDR and HLC capable cameras at his entrances , exits and open parking spots .
A environment protection or atleast IP 66 Cameras and enclosures are being used for your outdoor cameras and equipments !!
Please make sure that all your outdoor and exposed cameras such as those located at entrances , Exits , Outdoor Parking areas , Fields , peripheral protection have environment protection ratings at least of IP 66. IP 65 can only handle dusts however IP 66 equipments have protection against both dust and water to certain level . As a thumb rule generally Bullet Cameras are used for outdoor purposes because they have better environment protections .
A shock proof cameras are being used for survelliance inside buses , trains !!
A camera installed for the purpose of survelleiance inside moving vehicles such as buses , trucks and trains should have adequate shock proof ratings and aviation connectors to handle shocks and impulses during movements . A SD Card support is also very critical for such cameras .
An alert or warning messages in case of any network failures , connection breakdowns , Hard disk failures in case of large network of cameras !!
A large network where there are hundreds of Cameras and equipments it becomes imperative to recieve real time breakdown and equipment failure messages . A well planned system at such locations should be configured in such a way that you should recieve immediate warning messages on your emails , Cellular SMS form , Central Monitoring Software Stations . These features can help you in getting timely maintenance services by getting your real time attentions .
Reaping Audio capabilities of cameras is something that is very difficult to achieve !!
A rapid advancement in CCTVs these days have now enabled cameras to be use for listening and recording real time conversations as well . Some courts and Financial firms have started recording client conversations for recording their proceedings as their proofs . However inbuilt microphones inside cameras located at improper distances can hurt your faith . In such cases you can ask your installer to integrate a third party microphone with such cameras so that neither the view nor the sound quality is compromised . You can ask your installer to place such microphones at your workstations and meeting tables .
If hard disk failure protection is there inside your Surveillance Servers / NVR /DVR
Hard disk is something that store all the recordings in the for data . A harddisk failure can sometimes be detrimental for your business . So It becomes important for one operator to be aware of the RAID technologies . Raid support is something that enables data writing at two places simultaneously so that when one of the hard disk corrupts or fails the other hard disk contains all the important data feeds . But having RAID support in your NVR is not enough it has to be configured as well by your system integrator otherwise it will not work .
Slow Streaming on Mobiles and Networks !!
This is something very common that customers complain that their live streaming have lags at remote locations and their mobile view doesn't stream good . Your Installer often blames cable lengths or Internet speed . But this is not true everytime . If you have a Quad stream or tripple streaming CCTV and NVR that means you can have different streams for your Recordings , Live View , Uploading and mobile streamings .
