CCTV security systems HD-CVI stands for High Definition Composite Video Interface. This is a brand new technology in the security camera industry that provides a different method of transmitting video signals over coaxial cables. Until this new technology surfaced, analog CCTV video was limited to 960h video resolution. 960h resolution refers to the 30% increase in horizontal resolution, so the maximum analog resolution up to this point was 960 x 480 pixels. This has been the accepted limit to analog video transmission for many years. In order to achieve greater transmission would mean switching to digital video using either HD-SDI (High Definition Serial Digital Interface) or Network IP video formats.
Enter HD-CVI, a true alternative to Network IP solutions. HD-CVI uses a licensed video transmitter and receiver that is able to transmit up to 1080p video resolution (1920 x 1080) in an uncompressed format over the same standard coaxial cable that is used for standard CCTV cameras. This uncompressed video format is able to transmit over longer distances than either HD-SDI or Network IP cameras and without the latency and bandwidth issues that are so common. Additionally, HD-CVI is able to transmit video, audio and control (OSD or PTZ) over a single coaxial cable instead of requiring separate cables for each transmission.
What is really separating this technology from the rest of the options for video transmission is the cost effectiveness of HD-CVI. In most cases HD-CVI is around the same price as the older analog CCTV technology and is far less expensive than HD-SDI or IP Network transmission.
CCTV cameras are limited to 960h resolution which is 960 x 480 pixels. HD-CVI cameras can transmit up to 1080p resolution (2 Megapixel) which is 1920 x 1080 pixels. HD-CVI is capable of up to 450% great resolution and detail than standard CCTV cameras and DVRs.
CCTV can only transmit video over the single coaxial cable. Audio and control must be run over separate cables. HD-CVI can transmit video, audio and control over a single cable saving money and time.
The price point of analog CCTV and HD-CVI is about the same. You get more resolution for the money with HD-CVI.
There are some benefits to IP cameras over HD-CVI cameras that should be considered as well:
CCTV security systems cameras are capable of higher resolution than 1080p and the available resolutions will continue to grow in the future.
IP cameras are capable of POE power so you can transmit both power and video on a single ethernet cable if using a POE camera and a POE switch.
An IP camera is a network device itself so it can function without the need for a network video recorder.
If there is an existing network infrastructure and available network bandwidth is not an issue, it can be easier to add additional IP cameras to an existing network.
Rhodium security camera systems is one of the pioneers of HD-CVI technology so if you are considering this technology we are the experts in the industry. This technology should be considered if you wish to upgrade an existing CCTV camera system to megapixel quality video. By simply replacing the existing analog cameras and the DVR with our cost effective HD-CVI cameras and DVR you will instantly upgrade your system to megapixel quality video producing an increase of up to 450% in resolution! There should be no need to replace the existing cable infrastructure which is usually the most expensive portion of the installation.
If you are considering a new security camera system, we highly recommend our HD-CVI systems since it will cost around the same as the analog CCTV security systems installed today. It can provide you with the same resolution as most IP Network camera systems for a fraction of the cost and without the bandwidth and latency issues experienced with network cameras.
If cost is not a factor at all, then we recommend you seriously consider an all IP network camera system since the ethernet cable infrastructure can be used over again in the future to upgrade your cameras as higher resolution cameras become more available. Keep in mind that IP camera systems usually require network expertise to ensure that you have adequate bandwidth available inside the network and to ensure that the network camera system does not negatively impact your existing network infrastructure.
Requirements for an HD CVI security camera system:
When planning the installation of a HD CVI surveillance system, make sure to consider all the parts that will be needed.
You will need to select your cable infrastructure:
The best choice for HD CVI video transmission is high quality RG6 or RG59. Most professional security system installers will chose Siamese cable since that will include both RG59 for video, audio and control transmission and 18 gauge power wire for power transmission in a single run. We have tested both copper core coax cable and CCA (Copper Clad Aluminum) Coax cable and both have performed well.
You can use CAT5 or CAT6 cable with the same video baluns you use for analog CCTV cameras. This infrastructure does perform well, but the quality of the video is slightly degraded. It is still a dramatic increase in resolution over the analog CCTV camera resolution. Most people will never notice the difference in video quality. We estimate the degradation in quality to be around 5-10%.
We have tested prefabricate plug and play cables. Again, the resolution is excellent, but the video quality is also slightly degraded. There is around the same 5-10% degradation, again barely noticeable to most people.
You will need to select your connectors:
The most popular connectors are BNC Twist on connectors because no tools are necessary. These will work fine.
BNC compression connectors is what most professional CCTV installers will use for the cable connection. This is also what we recommend.
BNC Crimp Ons are also popular and will perform very well.
Select your power source:
HD CVI can be powered the same way as analog CCTV cameras. Most HD CVI cameras will require either 12V DC or 24V AC power. You can choose from various power distribution boxes or easy plug in power transformers.
Select your recording DVR (Digital Video Recorder)
You will not be able to use your existing DVR (Digital Video Recorder) with the HD CVI cameras. Like HD-SDI and Network IP camera systems you will need to select an HD CVI DVR in order to be able to record your HD CVI cameras. We offer a wide range of HD-CVI DVRs and in most cases, the HD CVI DVRs are the same price of even less expensive than their equal standard CCTV DVR or NVR and they are less expensive than most HD SDI DVRs.

Accoding to the statistics Victoria has become the nation's murder capital after a crime surge that saw the number of murders increase by nearly a third in the past year, the first large jump in five years.
The state has recorded more murders than NSW and Queensland in the past 12 months.
There were 66 murders in Victoria last year, according to the latest crime statistics, while NSW recorded 57 in the same period and Queensland had 51.
The murder rate had remained relatively stable in Victoria since 2011/12, with the number of killings hovering between 49 and 54 until the spike in 2015/16.
Victoria has been struggling with an escalation in gun violence in the past year but Police Minister Lisa Neville said deaths from firearms had decreased in the most recent figures.
Premier Daniel Andrews told reporters the increased crime rate was a trend that began six years ago. He described the latest figures as a "challenging set of crime statistics".
Mr Ashton said the homicide rate fluctuated over time but over the long-term tended to be stable. However, he said the homicide squad had experienced a very busy year.
Earlier this week, a man was charged with murder over a fatal daylight shooting at a busy shopping centre car park in Melbourne's north.
While the raw murder rate has not been adjusted for population growth, the "homicide and related offences" rate per 100,000 people was also up 17.3 per cent in Victoria last year.
Offences related to homicide include driving causing death, which climbed 26.2 per cent in the past year. It was also the first significant spike in that category in five years. Victoria's road toll has risen 16 per cent from last year.
The latest release from the Crime Statistics Agency shows Victoria's overall crime rate was up 13.4 per cent last year, with 535,826 offences committed in the 12 months to June.
Crime Statistics Agency Chief Statistician Fiona Dowsley said that while the total number of unique offenders had increased, there was a drop in the number of recorded offenders under the age of 25.
"Over the last year we have seen a four per cent drop in the number of offenders under 25, with the greatest change seen amongst 15 to 19-year-old offenders which dropped by 5 per cent," she said.
Police Association Assistant Secretary Bruce McKenzie said Victoria need a boost in police numbers to ensure it kept pace with population growth.
"On Grand Final week, we ought to be reflecting with pride on Victoria being the nation's sporting capital and not with shame as its undisputed crime capital," he said.
Opposition leader Matthew Guy said the latest statistics showed Victoria was being hit by a "crime tsunami".
"Make no mistake, these crime statistics are the result of Daniel Andrews' cuts to police, closing of police stations, and weakening of bail laws," he said.
In the past year there were 20 murders in South Australia, five in the Northern Territory and two in Tasmania. Western Australian and the ACT didn't state how many homicides were classified as murder.
Security cctv cameras and security footage will help to uncover these crimes Rhodium Security cameras will work together with Victorian police and Crime stoppers to make Melbourne Victoria a Best and safest place to live.

wireless security cameras Internet Protocol (IP) addressing for Communicating with Computers, Switches, Bi-directional
Receivers, Encoders, Axis Video Servers, etc.
An IP Address is a Numerical I.D. for a computer or a device that communicates via a network. A Sub-net
Mask tells your computer or device which I.P. addresses are local to your network and where to send
information. Changing the IP address and sub-net mask of your computer allows you to communicate with the
device that you want to configure; like a switch. When a switch is new, it comes with the factory settings. In
order for it to communicate on our network, we have to re-configure its IP address and Sub-Net Mask to ones
that are suitable to our network. In order to do this, we must first (temporarily) modify our computer’s network
settings. Once we have changed our computer’s network settings, we can change the IP values of the switch.
To change the IP settings of the Switch, you must open the internet browser at the top of the computer screen
and enter the factory default IP address of the switch -Click ok. The switch will have a “home page” that will
allow you to navigate through its settings. At this time you can enter the switch’s name, location, IP address,
Subnet mask and the Ethernet Interface. Ethernet Interface refers to the switches ability to send and receive data
in either half duplex or full duplex. For example, in Half Duplex information can move in only one direction at
a time. In Full Duplex, information can be sent and received at the same time in both directions between
The Point of Security Cameras
If you already have a security system, it may seem redundant to also have security cameras.
After all, if a security system is supposed to keep out intruders in the first place, ideally, you
wouldn’t have to use cameras to catch any burglars. Unfortunately, intruders can still break
into your home, even when you have a security system. Beyond security surveillance, there are
many other uses for security cameras, such as seeing who’s at your door or checking up on kids
or pets. Let’s take a closer look at some of the instances in which security cameras have been
useful in theft cases.
Security Cameras at Work
In some cases, security cameras catch intruders right away, and in other cases it takes more
time and police investigation to catch an intruder. Here are a few examples in which home security
cameras have proven useful in catching and preventing burglary:
Catch doorstep thieves
In December, a UPS worker in Texas was
caught on a security camera stealing an iPad,
which was a father’s Christmas gift for his
daughter. This savvy dad, had installed a camera
to monitor his front door, and when he
later reviewed the footage, it was clear what
had happened. When UPS didn’t respond to
customer service calls, he posted the video on
YouTube, which got their attention, and ultimately,
the iPad was returned.1
Nab burglars almost
When you have a live camera feed that alerts
you when it senses motion, you may catch
burglars in the act. One day, New York City
resident Levent Centiner was sitting at his office
desk when he started receiving emails
with live images from his motion-activated
camera. Upon receiving the images, Centiner
called 911 and the burglar was caught then
and there. Centiner is now an open advocate
for everyone setting up security cameras in

Crime statistics in Melbourne
Alleged offender incidents rhodium Security cameras
An alleged offender incident is an incident involving one or more offences to which an individual, business or organisation has been linked as an alleged offender. An alleged offender incident represents one alleged offender but may involve multiple victims and offences. One incident may involve offences that occur over a period of time but if processed by Victoria Police as one incident, it will have a count of one in the data presented in this section.http://www.securitycctvmelbourne.com.au/security-cameras
There may be multiple incidents within the reference period that involve the same individual, business or organisation. If there are multiple alleged offenders related to a criminal event, each will have their alleged offender incident counted once in the figures.
Where there were multiple offences recorded within the one incident, the incident is assigned an offence category of the most serious offence in the incident, known as the principal offence.
Security cameras in these sort of incidents help enormously to identify the offenders and these images from security cameras are evidence when stand traile.

The Importance of Home Security System
Why do we need a home security system?
Melbourne When you look at your family is number one, and your home, you know you want them to be safe and sound, always out of harms way. When you leave for work, or out you expect to come back to a smiling family, and to a home that is secure. But as they say, hope is not a strategy. The growing crime rates Melbourne infant in the world,across cities reflect the bitter reality. Many people overlook, ignore, and underestimate the need of taking appropriate home security measures.Rhodium security is the number one supplier of security solutions to Melbourne. A burglary or theft can lead to devastating consequences, both emotionally and financially. While the financial loss may be recoverable, the trauma inflicted on your family and yourself may last forever. So take a minute and think about this; is this loss worth.
It is proven that alarm systems help deter burglars. Another research conducted by the University of Melbourne proved that burglars would be hesitant to enter a home fitted with an alarm system. In fact, 31% burglars are likely to retreat from a home if they come across a security system. These figures reflect the effectiveness of home security systems and security camera systems.
Types of home security systems
There are many, many types of security systems for households and businesses. Typically, you will find major components such as a control panel, alarm, sensors, and detectors in a security system. Each component is integral to the system. You can opt for a wired security system or a wireless one, depending on your preference and budget. Some are Bosch, Hills, Honeywell, Tesla, paradox and more Rhodium security camera systems deal with most prestigious brads in the market.
DIY home security systems
In case of DIY security systems, all you have to do is follow the instructions that come with the kit. Most DIY security systems are wireless and easy to install. You can place sensors and detectors at main entry points such as doors, and windows.
How to choose
Choosing a security system for your home is probably the trickiest part of the whole process. Since there are so many companies out there, selecting the best one can be difficult. It is always recommended that you go for a firm that is well-recognized and ranked among the best Rhodium security has the experience and the knowledge to tackle the most copulated job.
When choosing a company, it is better that you first research a little, ask friends and family, and then make a well-informed decision.

Home security camera systems: your legal obligations and how CCTV deters burglars
Home is where the heart is and where you should feel that you, your family and your belongings are safe at all times, day and night.
With car keys, and expensive small items like tablets and mobile phones scattered around, a burglary can be costly; in a study by the Home Office in 2000, it was calculated that the average cost of a burglary was £2,300. With inflation, this now sits at £3,600. Of course, this could be increased further if a burglar steals your car keys and drives off with your vehicle.
A study by the University of Leicester found that CCTV systems were the single biggest deterrent in pre-planned crime
In April 2015 and March 2016, there were 375,034 cases of burglary in the UK. With this in mind, you may be looking to protect yourself and your home from this type of crime. Your first steps are to ensure you lock all doors and windows, and make sure there is nothing that can be climbed on to access upper levels of your property.
If you intend to take your home security further, you could try installing home CCTV. Here is what you need to know and consider before proceeding – and how the safety of your home could benefit.
The benefits of home security camera systems
If you think you’d like to take the next step in home security, it’s worth considering the following points:
A study by the University of Leicester found that CCTV systems were the single biggest deterrent in pre-planned crime. When burglars are selecting their targets, they are less likely to choose a home with surveillance.
Burglars are less likely to attempt a burglary in a home where a CCTV warning sign is present, as they know the homeowner is clued up about crime and has taken steps to prevent it, according to the same study.
The purpose of CCTV is to catch offenders in the act. This increases the chance of apprehension and prosecution, and therefore enhances deterrence. Police stressed the usefulness of community intelligence and public support in catching criminals when two men were arrested in South Gloucestershire after being caught on CCTV earlier this year.
Further benefits were seen in 2015, with the release of Lisa MacKenzie’s CCTV footage. The recording went viral after she fitted a camera to her property after a break in, and captured a potential intruder trying to enter her home.
A still from Lisa MacKenzie’s CCTV footage
Could dummy cameras work?
Dummy cameras could deter some thieves, but they shouldn’t be relied on – and experienced criminals can spot the difference. Plus, one of the benefits of CCTV is capturing the offenders in the act, so you need CCTV that can provide evidence of the crime and its perpetrator.
The law on residential CCTV
Before you consider installing a home security camera system, you need to understand the rules you must adhere to. This will stop you from breaching privacy laws, and allow for a smooth setup and use from the start.
You can install CCTV systems as part of your right to protect your property, but you must do so in a way that reasonably respects the privacy of others. To do this, you must:
Let your neighbours know that you’re installing a system – send a letter to keep it official.
Put a notice up to notify people that a CCTV system is in place.
Give consideration to whether the camera looks into neighbouring properties or public spaces.
You must also regularly delete footage that isn’t essential for the protection of your property.
CCTV could well be worth the investment for protection, peace of mind and prevention of losing valuable possessions. With a solid knowledge of CCTV systems, and the laws you must abide to, home CCTV is an excellent choice for your property.

Rhodium security camera system
Earlier this month, Moazzam Tariq was found guilty of sexual assault against a woman after a night out in Ontario, Canada. In sentencing, the judge mentioned extensive surveillance video footage that showed Tariq giving the complainant alcohol. This was marked as evidence that proved the woman could not consent.
The introduction of security footage in courtrooms as evidence is increasingly common. With the number of closed-circuit television (CCTV) cameras rising, the likelihood of images deemed relevant for criminal proceedings being recorded also increases.
However, while CCTV footage may arguably have assisted in achieving convictions in some high-profile cases, can it assist in the overall reduction of violence against women?
Where it has helped
A well-known example in Australia of CCTV helping solve a crime is the footage pulled from a shop on Sydney Road the night Jill Meagher was raped and murdered by Adrian Bayley. This footage was mentioned in his sentencing in 2013.
In the same year, Simon Gittany was found guilty of the murder of his partner Lisa Harnum. CCTV footage – taken from his own security cameras – was again interpreted as key evidence.
Beyond the courtroom, news media reports of crime are saturated with the use of CCTV footage. In both contexts, it is often seen to be decisive – an authoritative and objective witness that can tell us “what really happened”.
While used in a range of offences, its inclusion in instances of extreme (and public) violence against women can mean certain images receive significant and sustained media attention, and may remain online indefinitely.
The strength of CCTV in our public consciousness is such that questions of privacy are often dismissed as inconsequential. CCTV installed in the homes of family violence victims has even been considered.
But there are concerns
In Australia, women are far more likely to experience sexual violence or be killed by a current or former partner than a stranger. Both of these crime types are also most likely to occur in a residential setting, and therefore probably away from the gaze of Rhodium CCTV.
Despite these statistics, myths persist. It is assumed most rapists are strangers or that there will be clear evidence of sexual violence.
Circulating images relating to the sexual assault of Meagher or the victim in Canada – both of which took place near CCTV and in non-residential areas – risks further embedding these assumptions, given the persuasive power of media representation.
Also, some Australians have a very poor understanding of sexual consent. They assume non-consent will be obvious, or that a woman may lie because she has regrets about having sex. Placing great emphasis on CCTV footage in criminal proceedings to prove guilt is troubling for this reason.
Tariq was reportedly found guilty on the weight of security footage and not simply because the victim told police she had no memory of consenting to sex. News media have further reported that video evidence made up for the victim being an unreliable witness due to her consumption of alcohol.
Like most forensic evidence, CCTV footage still requires interpretation. And yet when admitted as evidence, it can take precedence over other witness testimonies. This is particularly concerning given that sexual assault cases often rely on victim testimony.
Already a traumatic process, if a victim’s account comes into conflict with CCTV footage, the strength of the prosecutors’ decision to proceed in a sexual assault case diminishes.
With only 20% of all sexual assaults estimated to be reported to police, CCTV footage – either its absence or its conflicted account – could negatively impact this rate.
It shouldn’t be essential
Even if CCTV were installed in homes to reduce violence against women, it may not help.
Simon Gittany subjected Lisa Harnum to intimate partner violence prior to her death. This included the installation of security cameras facing into their apartment for the purposes of watching her.
On the day Harnum was killed, however, Gittany had switched all but one off in the morning. Installing CCTV may not prevent violence against women in residential areas, but instead extend it.
Thinking beyond the immediate utility of CCTV in specific criminal cases, images reproduced for other purposes – that is, beyond finding a “guilty” verdict – should also be considered in the context of violence.
The “cultural afterlife” of criminal evidence can be unmediated in its use. Materials can be used in new ways, such as artwork, and often without the consent of individuals depicted.
Not only this, the unnecessary reproduction of CCTV footage that replays a traumatic moment in someone’s life may be considered unethical and harmful.
With the expansion of CCTV in public and private settings, it is important to interrogate its purpose in both the courtroom and the news. Rather than assuming its account as “best witness” or simply harmless, we should revisit underlying causes of crime so that CCTV need not be essential in reducing violence against women.

A POLICE taskforce tracking the notorious Apex gang and other violent crimes is investigating three vicious street attacks within hours, including a knuckle duster bashing.
Police believe a group of men, described as “African in appearance”, attacked one person in Dandenong on Tuesday morning and two more the next morning in a robbery spree.
Investigators attached to Operation Cosmas, a statewide operation to combat Victoria’s spreading carjacking and aggravated burglary scourge, have appealed for public assistance.
The worst attack was the last — on Wednesday morning — when two men armed with knuckle busters assaulted a man who was walking along Thomas St about 4.40am.
Without saying a word, they punched the victim in the face and head and stole his mobile phone and an amount of cash.
They also stole a distinctive red and black backpack.
Home Security Camera systems
About five minutes earlier, three men threatened a man on Thomas St and demanded his wallet and phone.
When the victim refused, the offenders punched him in the face but he managed to flee.
On Tuesday, a trio chased down a victim who was walking home along Mason St about 5.25am, assaulting him as he tried to run away.
His bank card and mobile phone were stolen, as well as a small amount of money.
Investigators have released an image and CCTV of two men who they believe may be able to assist with their inquiries.
Operation Cosmas was rolled out last month. It aims to prevent, deter and investigate aggravated burglaries and carjackings across the state.
Its formation followed Taskforce Tense, which was charged with cracking down on gang-related crime in Melbourne’s southeast.
The Apex gang originated in Melbourne’s southeastern suburbs and is mostly comprised of youths of African and Pacific Islands heritage.
It has been linked to a string of home invasions, car thefts, and the Moomba riot in the CBD in March.
