Emerging Video Technologies – Pt5 Storage on-board IP Cameras

Posted on by

Today, we take a look at On Board storage for IP cameras

Potential Benefits:-

Some camera locations have limited or unreliable bandwidth. In those lcoations, ensuring that video can be streamed and recorded remotely can be expensive (or simply not possible). Putting storage inside of an IP camera can eliminate this problem. Of course, some network connections will be needed to remotely view/download record video. However, this will only need to be done periodically.

Cost: While storgae costs drop continuously, today the cost of on-board storage is far higher than centrally storing video in hard drives. Moreover, for most video surveillance applications, it is simply not possible to solely store video on-board IP cameras as it is not technically possible (with the exception of  suppliers supporting hard drives inside or attached to their cameras)

  • End User Risks
    Using on board storage may force compromises in the length of storage or the quality of storage (because of limitations on how much video can be stored inside the camera). Additionally, most VMS systems do not support remote playback of video recorded on an IP camera. This could make it difficult to access and use this video.
  • Installer Risks
    If the on-board storage cannot be remotely accessed using the existing VMS playback, the installer may be called for additional service calls. Some systems will require a technician physically remove the on-board storage while others will require downloading raw video files.

Taken from the ‘Emerging Video Surveillance Guide 2010’ from http://ipvideomarket.info/

we at IntegratedCCTV agree in part with the report – however, we still think that a camera recording in a continuous loop, just enough to cover a 3 9’s network (99.9% allowable down time, 43 minutes per month) and then using technology such as March Networks’ Shadow Archive feature, means that the system can synchronise video lost during the network downtime, with little effect on the overall system…………this is new and probably not known at the time of the report, but it is worth noting when discussing the above!!!

Navtech Radar

An interesting twist on Perimeter protection!

We became aware recently of a new, emerging technology in the Security Industry……….Radar

It’s not a new technology, but certainly new in our industry.

Is it expensive?

Well, yes…….but, you need to look beyond the capital outlay and see what it replaces…

historically, protecting a huge perimeter, such as that of an airport, would involve 10’s or even 100’s of sensors, whether beams or detectors, alarm or dedicated CCTV beams such as those from companies like Optex etc…..

but, one single Navtech Radar unit, placed centrally, can monitor movement in an 800m 360 degree zone………and link various zones to multiple cameras……controlling PTZ cameras such as MIC-400 from Bosch or the new and excellent 360 Vision Predator product, moving them automatically to moving objects and dynamically tracking as the object moves within the detection zone………

Offering a complete revolution of the mentioned 800m 360 degree view in ONE SECOND this represents a very different way to think of sensor detection.

We think this is a very exciting new product, there is defintely a cost increase, but we are prepared to bet that if installation costs and labour are factored in, there is very little in it!

Navtech’s website can be found here – let us know what you think!

CCTV reviews.

Over the past few months we have reviewed many products. Below we link to some of the most popular posts and look for comments  from yourselves as to your views.

Engineers and sales alike, join in the debate and let us know what your experiences of IP CCTV really are. Too expensive ? too difficult to install or just too hard to sell at the moment . We want to know what you think.

Are your sales down this year?

What do your customers think about you …find out

Just a few of the posts that have created a bit of debate and interest so far register today and feel free to comment and blog giving your views and comments about your products and company or just some interesting views you think that we should all know about.

Cathexis Hybrid DVR

Posted on by

Cathexis catSytems.

Cathexis are a well established manufacturer of digital surveillance equipment. The catSystem range offers both hardware and software products that boast a level of flexibility not seen in many products of this type.

Customised for every requirement.

The catSystems have the ability to to allow the customer to specify a custom built recording suite that allows hybrid integration of both new and existing cameras, both analogue and IP.

H.264

Using H.264 compression technology high performance is assured. Used extensively in the retail and mining sectors, a powerful database engine allows real-time recording and monitoring. This, synchronised with audio allows customers to build a system exactly suited to their needs. This solution means no over specified unit costing more than is actually required allowing more budget to be spent on quality cameras as well.

Hybrid DVR solution.

The Cathexis DVR has an application to meet every need it has been engineered for stability and reliability and the fault monitoring side of the product with full system logging is a godsend for installers. It is highly net-workable for hybrid options and remote monitoring and maintenance gives CCTV control staff high levels of functionality through advanced CCTV software.

Integrated CCTV.

Finally third party integration has been considered a must in the the design of this product allowing fire systems, access control and EPOS all to be seamlessly integrated. A robust product designed for blue chip companies can also be used by medium sized business as well. A visit to the website would not go amiss.

IPCCTV over WIFI

Posted on by

The scenario.

Picture the scene (pardon the CCTV pun!)

Building A is 500 metres from building B

There are 4 cameras on building A, one on each corner (don’t you just love perfect worlds!) and they need to be viewed, recorded and controlled (did I mention they were PTZ?) all from building B

THE PROBLEM

The two buildings are separated by a river – a very nice river, big boats coming up and down, delivering stuff to dockside delivery points.

No chance of cabling then….. Until recently, the answer was to use free range wireless transmission solutions, such as RF, Microwave, Laser etc……… but, history shows that each has it’s positives and negatives but they all share one common negative….. expense.

ANOTHER WAY?

With the upsurge in IP, there is another way………..Wifi…………ok, professional wireless is what all the proper ‘wifi’ consultants will call it, but wifi nonetheless.

You see, Wifi does not have to be a one to one transmission solution…………. with typical bandwidth of 54Mbps, even if we halve it (because clever network guys will tell you that there is always a drop over distance etc), we can expect a 27Mbps bandwidth allowance……

So, take our building A and B scenario…. cable all the 4 cameras to a central point (it is a perfect world after all !) and either convert to IP from analogue using encoders (or, if we are to get this industry into the 21st century let’s push the boat out and go true IP cameras!) and connect to a regular 4 port network switch…

Take the output of that switch and insert into something like the Silvernet product range….. 1Km line of sight, pre-configured to create a point to point connection…..go to building B, position the receiving unit line of sight to building A and either decode back to analogue or bring one, neat, simple CAT5/6 cable out and introduce to the network for full control and view of the system ! simples !

THE THEORY AND THE PRACTICE

Ok, we don’t always have a perfect world, clearly, however, using the above solution, we have sent 4 cameras over the one link….saving a LOT of money:-

RF/Microwave/Laser = at least £2000+ for EACH camera

WIFI = under £1000 for a 1Km link with the ability to run a good few cameras – typically a PTZ IP camera would be around 5Mbs and a static at around 2Mbs

But, just like RF/Microwave/Laser, if the Wifi states ‘Line of Sight’ or LoS, then it REALLY means that…..so much as a leaf on a overhanging tree, or, in the case of our River separating the two buildings, boats that might momentarily ‘interrupt’ the signal, it is imperative to ensure that the TX and RX units are positioned so as to enjoy clear and uninterrupted transmission!

The cost savings are impressive and just might give this industry the excuse to use IP !!
