Walkie Talkies Solution Over the Internet PTT

We are all familiar with the normal standard walkie talkie that we see guards, stores, restaurant, police and many other agencies or groups using.

What we may not be familiar is that they are mostly controlled items as their primary build and use was for enforcement. Their larger and longer range cousins were for military and defense usage.

Now the traditional walkie talkies go over the air either in analog or digital forms. There are some variations such as over the satellite.

Over the last few years with the increased usage of internet and the conversion to wider spread of internet usage with its terminals. Walkie Talkie functions have also had a migration across with many methods. The most widely spread version is on the IMS platform. Specifically the PUSH To Talk system. In some sense it is like a digital intercom except it can go one to one and one to many.

The presence of this function is in many Chat applications and other dedicated built applications. The hard ware need not be specialised. But there are specialised hardware available for those whom prefer specialised hardware.

The for public use especially the licence not required category normally has a small throw of below 5km. Further than that a licence is required per device and only trained users with licences to use can own and use the units. Other person allowed to use would normally be enforcement personnel.

So with the short range limit or licenced required for device and operator higher range variants, what you may end up with would be clusters of connected persons then needing to swap to a mobile phone or land line for longer distance communication.

PTT in its bearest state just needs data networks based on IP (Internet Protocol). So it can be hosted on wifi, mobile internet and data over satellite.

PTT could be in one group or a one to one communication of known users.

The friendly part of PTT even if you are in one site. You could also create purpose/role/responsibility or other reasons for grouping. Even within one site. And a single user can belong to many groups.

With above configuration of usage. You can also extend the usage to multi sites. Same features. But as different groups. And number of users could belong to groups from other sites too.

Now the traditional sets would have cost a huge amount of money. As such to switch over can be a barrier. Also having too many different technologies that dont talk to each other could put off any sane user.

However there are solutions to integrate the old with the new. As in the case with either embedded gateways within the device or separate gateways per site.

With this you would retain the ability to use the old sets using unverified call signs and unverified locations. With the current by user login, password, gps position with visual verification by video and still image new technology PTT (internet walkie talkie).

The best part is that the technologies can mix and the features can be extended within the environment even down to putting digital fences using GPS and other positioning tools. Hence creating what is called a geo fence. This can be used in a positive manner of providing notification to the user that he is partroling further than his agreed area. And for the central monitor that the user has exceeded his area of partrol which could mean something that is bad has happened. And with the right device have even control to remote enable camera, communication and more for verification that the user is fine.

Valuable in Transit – One Example Cash In Transit (CIT) and ATM Cash Cassette Replenishment


The risks of valuables transportation services (cash, jewelry, intellectual valuables etc) along with valuable replenishment services (ATM cash replenishment and retrieval) to name a few are high as are the cost for the services.

Specifically Cash In Transit (CIT) or the service activity of transporting money for legal entities is a large business due to the level of risk. This normally requires many factors to reduce those risks. But with cost as a consideration viability normally could reduce the measures that are taken. Thereby directly increasing the risk.

The task normally consist of the pick up activity (This is where verification actvities and accountabilty take over activities are carried out.), the actually transportation activity (This would be remaining vigilant, Protecting, driving and avoidance) and finally at the destination is the Handover activity (where verification again take place, accounting and transfer of responsibility)

In Malaysia additional activities that are also outsource to guard companies the actually loading of money into ATMs. Hence even more risks are exposed.


Some of the risks that arise are : –

Any activity dealing with cash or valuables and not handled by the owner themselves bring about the following: –

  1. Honesty
  2. Reliability
  3. Attack
  4. Theft (internally and externally)
  5. Loss by any other means (fire, wind, earth quakes, acts of nature, etc…)

Addressing the Risks

Even though the activity may bring risk the rewards can also be fulfilling for the right people. To ensure the risk is worthwhile and to reduce them some measures must be taken. The following are the ones taken today:-

  1. Primarily hiring honest people.
  2. When not available to reward people that will reduce their willingness to commit the crime.
  3. Then is to use secure carriers that limit the persons whom can access the item. (i.e. strong boxes with locks/combination, key release, biometric, a mix combination and many more.
  4. Have good handling processes. (Limited knowledge and access to those processes, Check in, multi verification medium, methods and more)
  5. Tools, Tracking and Recording (TTR)

Raising the Bar

In addressing the act of raising the bar beyond the cost of vehicle, fuel and man hour rate, There is more to be provided with justifiable cost increase but higher benefits in terms of security and possible reductions on other protection received as rewards in reduced insurance premiums and more for the companies involved.

Tool, Tracking and Reporting (TTR)

Though there were 4 other items of main issues and measures needed to be addressed , we will only deal with the fifth one which is Tools, Tracking and Reporting. Though it is not said that there is none today (And there cannot be no measures in place), the measures used could be updated and upgraded to increase transparency, insert digital tracks with alarms when conditions not met and reporting of the overall activity (in action and when action completed).

The three main components to be enhanced is the vehicle traceability, the cargo with path validation and personnel support. This by tagging with real time tracking visually, audio and GPS positions. of all components involved in the service/activity.

With all those components in place the hidden or unknown better yet described limited information for verification previously available possible due to technology. The increase of it in tandem with the tried and proven processes, illuminated by the current availability to provide real time viewing with evidence (real time and post time) of the service being carried out.

But not withholding the best improvement yet, the ability to provide remote support when the risky events occur. Such as calling in relevant personnel and parties when robberies or interception of the valuables occur.

This in itself will increase the risk factor to the criminals and increase the safety factor to all provider personnel and customer valuables.

But though it may improve capabilities. It does not eliminate the original risks at all.

Dash Cameras – For Cash In Transit, School Bus, Tour/Public Buses, Fleet Management, Private Transport

Security for vehicles and their cargo (Human, animal or inanimate) has been long in the market in various forms. The most recent and has now got more interesting is the CCTV on the go in the form of action cameras, dash cameras (in and out of cabin) and body cameras.

The technology initially started with the stand alone forward facing cameras mounted on the dashboard (later on Mirror). This was for on coming collision protection and incidences.

The Technology included functions such as on board/external memory card or both recording, G-sensor for orientation support, Motion Detection (for both stationary and on the move detection), 140 – 170 degree vision (some even wider today), Parking monitor, Loop recording, Resolution from 480p upwards, High frame rate from 15 to 60Fps, Multi lingual,

Then came the dual camera solutions

Then came with Wifi enabled and phone application. Generally IOS and android supported.

Then came GPS enabling and subsequently near real time remote monitoring via cloud and point to point mapped monitoring.  (phone support via app in this segment is also now available.)

 Driver attentive monitoring and lane straying  features.

 Satellite (GPS), tracking and real time (near Real time) Video tracking and verification.

 Passenger attendance and tracking via RFID. (3d barcode, barcode, nfc, app attendance and many more methods possible too.) This could be the replacement of tickets and could be the enhancement of tracking beyond driver and passenger recognition and attendance for school and factory buses.

Multi camera position support. Includes external front real viewing, but also wing viewing and internal sectionalised multi position in cabin viewing.

This has now come further in the development of feature rich solutions of protection and monitoring on the move. 

For the private vehicle purposes to provide protection in disputes, high risk situations and more with the tracking right down to passenger.

On the commercial transport for passenger tracking of attendance RFID etc (reducing time lost going through passenger manifest for reassembly during pit stops, as well as initial embarking and disembarking.) GPS and Video Surveillance for tracking transport progress of the trip for passengers pick up by family members at destination. For company estimation update of travel and much more. Great for school buses as well. For parents and school peace of mind.

On fleet management of cargo and such for commercial goods movement, which includes oils and crops. The information support includes weight, speed and more.

Black box support for after the fact investigation, for any disputes and incidences.

Driver attention and stray detection monitoring with alerts to ensure better safety of the road captains.

The possibilities are getting to be endless. Reporting and accountability is possible at not so high a price today with the advancement of technology with availability.

And the features are getting richer by the day.

Cloud Able Network Mobile CCTV with GPS for Vehicles (Cloud able Network Dash Camera)


Today Vehicle security is required not only when it is not moving and locked but also when its on your journey.

With todays dash cameras from stand alone single forward facing, to dual outward facing cameras (both front and back) to high resolution are normal expectations.

More current are the networked versions which are locally networked versions that require a smartphone, tablet or pc/laptop to transfer videos out via applications.

Or the latest which is on Cloud access networked solutions with GPS, power down relay back up solutions (for recording last recording prior to power off), add on microphones, multi camera even for in cabin with optional audio. Excellent for tracking your precious cargo (which could be your family or customers in the case of ridesharing/commercial controlled transport) or just for personal safety.

The advancement of mobile CCTV further to the advancement of standalone dash cameras is the enabling of recording on an dedicated recorder which can support more cameras. Which now gives you more options of placement of cameras to not only be forward and backward facing from inside the cabin out but also to have wing support and or in cabin too. With this setup the audio visual can also be maintained as in some dash camera offerings. More importantly is the ability to have web management and viewing with possible application support on smart devices. Hence getting multi level monitoring if you wish for the security and management of your vehicle security. And with the add on of GPS that visual can have coordinate tagged positions further enhancing your management and tracking.

You get data analysis features that can be enabled.

You have file integrity management.

You have multiple display just like in any cctv management setup. You have listed format records of your recordings. you have search functions that are easy to handle. Playback controls that are easy to manage. Privacy features such as blurring of images. G-sensor support for orientation in movement and mapping.

Most of all you have in simple easy to view and manage controls.

The components are simple to connect and easy to add on.

An example specification of a system could be as above.

IP rating on electrical products briefly explained

Now when buying electrical products from time to time you would note that in the information it would say IP xx rates. Example for outdoor suitable devices the common rating claimed would be IP 66 which is state to have certain criteria suitable for outdoor use.

To quote a description from one website (credits listed as a link)

“IP (or “Ingress Protection”) ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.” – www.enclosurecompany.com/ip-ratings-explained.php

To quote another description from another website (credits listed as a link)

The IP (International Protection) Rating of a product is represented by two numbers. The first digit is the protection rating against solid foreign objects (i.e. dust) and the second digit represents the protection against the ingress of water. The ratings available and descriptions are as follows:

First #
Solid Foreign Object

Second #
Water Ingress Protection

no protection

no protection

protected against solid objects up to 50mm

protected against vertically falling drops of water

protected against solid objects up to 12mm

protected against direct sprays of water up to 15º from the vertical

protected against solid objects over 2.5mm

protected against sprays of water up to 60º from the vertical

protected against solid objects over 1mm

protected against water splashed from all directions

protected against dust

protected against low pressure jets of water from all directions

totally protected against dust

protected against strong jets of water

protected against immersion

protected against complete continuous submersion in water

To get the most current explanation the best place of course would be to get it from the standards body itself that has ratified (created/agree/provided) these standards.

But what you need to know and be aware is that there are some standards and regulation that provide you some minimum and in most cases best protection for your purpose.

So the next time you have a product that you require for use in possibly challenging conditions do look for the one with the features most relevant to your need.

Price isn’t always a factor of quality or suitability. Read the specifications and standards adhered to.

CCTV Monitoring Temperature and Humidity

CCTV systems have increased in the features that provide for specific functions. They range from low light (IR or sensitive CCD/CMOS sensor), facial recognition, stock count keeping automatically updating the stock levels, to motion detection and many more features.

Today the latest entrant to those features is temperature and humidity monitoring. This is especially useful for environments that require the ability to capture and monitor these changes. Industries that can make good use are from farming to monitoring environmental changes to sensitive products such as wineries, rooftops, computer rooms, telecommunication centres, utility centres and more.

CCTV Signal and Power – The different methods for the different technologies

This is a follow on from our previous article CCTV Basics http://kanshare.com/Solutions/cctv-basics-ip-cctv/

Today is about power and video. First is power. Everything needs power.

The most basic CCTV setup is the distributed power setup. This is easier as you grab power from the nearest socket or extend from the nearest power socket or lighting point.



The next format is the centralised power supply system. This requires wiring from camera all the way back to the central power supply. Generally you drag one cable for one camera. There are occasions some may split the power to cameras along the way. But this method is the surest way to having problems in the long run. In terms of trouble shooting and also the more technical which is power drop.

Below are the types of cables that can be used for a power solution for CCTVs. But they all have their particular use, methods of use and characteristics. A little more descriptions as enclosed in the slide.


Now as power has been provided separately. The choice of video transmission is equally varied. And basics limit the options to the relevant technology. But in over the years innovative solutions such as transmitters receivers, converters and baluns have allowed cross transmission of video on different cable and wireless solutions.


Even further creative uses of older technologies have even provided the single wire solution for both Power and Signal. And they totally differe from the analog twin signal and power cable.

These technologies actually transmit the both the power and signal over the very same cables.

POE. Power Over Ethernet uses the friendly computer cable to make connection between the recorder/viewing station. As the name says there is power and signal transmitted over the ethernet cable with RJ45 connectors.

PLC Power Line Communication or sometimes known as the HomePlug. Transmit both the video and power over the normal house power line. Very stable. Hardly any wiring required in addition to whats there.

POC/EOC Power Over Coaxial and Ethernet Over Coaxial. Now the former is relatively new as traditionally you did not send power over any coaxial cables. Reasons very obvious which you can read up more on the purpose of cables and their types. (You could wiki it and more. Maybe we will do a little write up in the future.) The later Ethernet Over Coaxial is relatively old as it is similar to the token ring network with the exception of the speed and the finickiness of token ring which required very strict cable types, lengths and terminators on each end.

We have written a little bit about this in brief for our customers. But soon there will be some publishing on this here too. Look out for it.

All in all to sum up, the security market today is beyond national deployment in the more staid governmental policing and army. Nor is it the sole commercial controlled security services industry which requires trained personnel (which it used to have and abundance of source in the past. Today they require huge investments into training which is sometimes daunting).

You now have an array of solutions to put part of the monitoring of your security in your hands. And to support the organised bodies to enhance their reach to keep everyone safe.

IP CCTV in its basic form isn’t basic till bare bones. It in general has a rich feature list that in the analog CCTV offering would be considered rather advanced.

Why where the basic analog cctv which today is now way advanced from its predecessors, the IP CCTV is based on a form of computer and immediately some networking.

That in its base form gives you immediate increase in features. They start immediately by being networked hence easily integrated into a normal IP data network. When in that network its access is easy but along with that easy access there is already some basic authentication requirements unless turned off or given a standard default.

cctv basics - ip cctv


It can work as a stand alone system right from the start. It provides security to access it, it has open standards to viewing such as pcs, laptops, smart devices such as smart phones, tablets and also dedicated devices. Even recording can be on any device beyond dedicated devices.

Increasing number of view points and devices to capture as well as view is pretty simple.

cctv basics - ip cctv


After adding the devices this is where it can be pretty back to front as opposed to the analog systems. To have a dedicated recording and playback monitoring device now you add a dedicated recorder or multiplexed switching NVR (Recorder)

CCTV basics – IP CCTV

Today the IP CCTV options are so diverse includes wifi based systems and more. Especially visible in the stand alone systems from the more reknown IP product manufacturers where they provide you a wired option in addition to your wireless option(wifi).

Even on the wired option they have improved to provide reuse of as much legacy infrastructure (Coaxial cables, power sockets and more) to make the migration to getting more out of your cctv and giving your monitoring more freedom yet the ability to stay static and have escalated viewing functions.

Its level of mobility is high to being accessible far and wide locally via wire or wifi till the internet on a peer to peer basis (with complicated configuration) or simplified cloud solutions. Its all in your hands.

CCTV Basics – Analog CCTV

Close Circuit TeleVision is a tool used in security and monitoring.

In its most basic form just had a camera a screen on the other end, wires to interconnect the devices and power to both end. On the monitor end the connectors started from a coaxial version to a converted variant to RGB format using RCA connectors to d-subs. No recording.

CCTV concentrators with switcher function.

CCTV Concentrators with switcher functions.

As the need for more points to be viewed at a time as less men were deployed then came concentrator boxes such as switchers to switch between camera views. This reduced the installation of screens and one to one deployments of viewing devices. It also brought focus back to the security monitoring team. But it still left a hole during the switch over time. The first versions were manual then came the auto versions based on timers and other logic.

multi screen cctv

Multi screen CCTV

As the need to simplify, shrink foot print of equipment install base, multiplexers were the next innovation on the viewing end of the cctv solution. This gave more than one camera view on one screen. Married with switchers this kind of concentrator gave more options and less security breach opportunity as the viewing was for longer periods of time per multi view.

cctv multi screen with recording

CCTV multi screen with recording

After the evolution of dispersed viewing providing more tools to the security personnel providing a total security solution, evidence was required for prosecution and more. This is where the recording function appeared as the requirement. This combination did not change very much with the exception of accessories such as controllers(joy sticks, keypads, mouse pads, keyboards etc), zoom tools and more.

Today in the analog arena you have High definition video solutions currently the common resolutions are 1Mp (720p), 1.3Mp (960p) and 2Mp (1080p also refered to as full HD).

Analog solutions also have some wireless solutions. Most on radio transmission up to microwave solutions that are commonly proprietary.
