Langkah-Langkah Cara Memasang kamera cctv
Berikut adalah tips dasar langkah-langkah cara untuk memasang kamera CCTV (Closed Circuit TeleVision):
1. Tentukan kabel yang sesuai
Untuk kabel CCTV, Anda juga dapat dengan menggunakan kabel RG59 Siamese yang telah terdiri dari kabel video dan kabel power (positif dan negatif). Kabel RG59 Siamese juga merupakan kabel standard yang sering digunakan untuk instalasi CCTV.
2. Tentukan lokasi dan area pantauan CCTV
Lokasi pemasangan CCTV juga bisa Anda tentukan berdasarkan jarak pandang yang hendak dimonitoring (apakah dekat atau jauh) dan apakah untuk dalam keadaan gelap atau terang. Dari situ baru Anda bisa tentukan titik pemasangan kamera CCTV.
3. Prioritaskan penempatan kamera CCTV di bawah atap/ tempat terlindung
Terutama untuk pemasangan CCTV di rumah, prioritaskan letak posisi kamera CCTV dibawah atap karena bisa melindungi kamera CCTV Anda dari hujan, angin, dan sebagainya. Selain itu, penempatan di bawah atap juga biasanya telah memberikan tampilan view yang lebih baik dan mudah untuk menarik kabel jaringan.
4. Cari titik untuk mulai menarik kabel dari luar ke dalam
Setelah menentukan titik pemasangan CCTV, berikutnya adalah mencari titik masuk untuk dapat menarik kabel RG56 dari luar ke dalam.
5. Penempatan monitor dan DVR
Monitor dan DVR adalah alat-alat yang telah melengkapi sistem CCTV Anda. Jika kamera CCTV biasanya ditempatkan diluar, maka DVR dan monitor digunakan untuk dapat membantu pemantauan dari dalam ruangan. Tentukan tempat dimana monitor dan DVR akan diletakkan.
6. Memulai penarikan kabel
Setelah didapatkan titik kamera CCTV dan lokasi penempatan monitor dan DVR, maka berikutnya adalah menarik kabel RG59 yang telah menghubungkan antara CCTV dengan monitor dan DVR.
Saco-Indonesia.com - Minggu sore pekan lalu, Gerald begitu bersemangat menangkap bola. Matanya sigap merespon lemparan bola dari pelatih. Tubuhnya sudah banjir keringat dan baju bola serba hitamnya basah. Dia berlari dengan handuk menempel di tangan menuju penjual air kemasan di luar lapangan. Hausnya sirna tersiram isi botol berkeringat uap es.
Bersama rekannya, Izzan, Gerald keluar lapangan saat jam istirahat meneguk air kemasan mineral untuk menghilangkan dahaga. Saban pekan mereka berdua datang ke lapangan hoki di Senayan, Jakarta Pusat, mengikuti Sekolah Bola Tik Tak. Keduanya merupakan bekas peserta didik Liverpool Internasional Football Academy. Sejak sekolah bola Liverpool ditutup, mereka tetap berlatih di lapangan Hoki Senayan dan bergabung dengan Tik Tak.
Kepala pelatih Sekolah Bola Tik Tak Yahya mengatakan Liverpool Internasional Football Academy sudah tutup sejak Agustus tahun lalu. Tidak ada alasan jelas penutupan sekolah sepakbola bertaraf internasional itu. Padahal sejak berdiri Juli 2011 peminatnya terbilang banyak. Total peserta didik saat tutup di Jakarta dan Pekanbaru sebanyak 500 orang.
"Sudah tutup sejak lebaran kemarin," kata Yahya kepada merdeka.com akhir pekan lalu. Selain tutup tanpa alasan, pengelola Liverpool Internasional Football Academy juga enggan memberikan pemberitahuan kepada para peserta didik.
Seorang pedagang air kemasan di Senayan mengaku disuruh berbohong oleh pihak Liverpool Internasional Football Academy terkait penutupan sekolah sepak bola itu. "Kalau ada yang tanya kita disuruh bilang pindah, padahal tutup sejak puasa tahun kemarin," ujarnya.
Yahya selaku mantan kepala operasional di SSB Liverpool mengaku sejak sekolah bola waralaba Liverpool itu hadir di Indonesia banyak tawaran untuk membuka cabang di berbagai daerah. Namun sayang, baru membuka dua cabang di Jakarta dan di Pekanbaru, Riau, mereka sudah tutup. Padahal kontrak kemitraan di Indonesia sebagai waralaba berjalan lima tahun.
Yahya mengaku tidak tahu alasan penutupan SSB Liverpool lantaran manajemen SSB Liverpool menolak memberi keterangan. "Kalau mau dibilang rugi kayaknya enggak. Kan kontrak waralaba itu lima tahun, ini baru satu tahun lebih sudah tutup," tutur Yahya. Kabar berkembang lantaran masing-masing pemodal asal Indonesia mengundurkan diri tanpa sebab.
Untuk bisa menikmati latihan di Liverpool Internasional Football Academy biayanya tidak murah mulai dari Rp 750 ribu sampai Rp 1.6 juta. Sedangkan Sekolah Sepak Bola Internasional Arsenal mematok tarif pendaftaran Rp 500 ribu untuk usia di bawah enam tahun dan Rp 1.5 juta buat umur di bawah 16 tahun.
Yahya selaku kepala pelatih di Tik Tak dan pernah melatih di SSB Arsenal dan Liverpool itu melihat sekolah sepak bola asing tidak serius mengembangkan sepak bola Indonesia. Keberadaan mereka dinilai mengambil kepentingan bisnis.
"Kalau mereka serius, mereka bikin fasilitas di sini. Mulai dari lapangan milik sendiri, yang ada semua sewa," kata Yahya. Meski mereka tidak menjual pernak-pernik klub, namun keberadaan sekolah berkedok klub sepak bola internasional sangat menguntungkan. "Termasuk melebarkan nama mereka di sini."
Anggota Komite Eksekutif Pembinaan Usia Muda Persatuan Sepak Bola Seluruh Indonesia La Siya mengaku tidak mengawasi secara khusus terkait menjamurnya sekolah sepak bola bertaraf internasional. Menurut dia, kehadiran SSB asing hanya mencari keuntungan semata hal wajar. "Terpenting SSB asing itu ikut membangun perkembangan sepak bola Indonesia pada usia dini," katanya saat dihubungi melalui telepon selulernya.

Advertisement Politics Obama Finds a Bolder Voice on Race Issues
As he reflected on the festering wounds deepened by race and grievance that have been on painful display in America’s cities lately, President Obama on Monday found himself thinking about a young man he had just met named Malachi.
A few minutes before, in a closed-door round-table discussion at Lehman College in the Bronx, Mr. Obama had asked a group of black and Hispanic students from disadvantaged backgrounds what could be done to help them reach their goals. Several talked about counseling and guidance programs.
“Malachi, he just talked about — we should talk about love,” Mr. Obama told a crowd afterward, drifting away from his prepared remarks. “Because Malachi and I shared the fact that our dad wasn’t around and that sometimes we wondered why he wasn’t around and what had happened. But really, that’s what this comes down to is: Do we love these kids?”
Many presidents have governed during times of racial tension, but Mr. Obama is the first to see in the mirror a face that looks like those on the other side of history’s ledger. While his first term was consumed with the economy, war and health care, his second keeps coming back to the societal divide that was not bridged by his election. A president who eschewed focusing on race now seems to have found his voice again as he thinks about how to use his remaining time in office and beyond.
In the aftermath of racially charged unrest in places like Baltimore, Ferguson, Mo., and New York, Mr. Obama came to the Bronx on Monday for the announcement of a new nonprofit organization that is being spun off from his White House initiative called My Brother’s Keeper. Staked by more than $80 million in commitments from corporations and other donors, the new group, My Brother’s Keeper Alliance, will in effect provide the nucleus for Mr. Obama’s post-presidency, which will begin in January 2017.
“This will remain a mission for me and for Michelle not just for the rest of my presidency but for the rest of my life,” Mr. Obama said. “And the reason is simple,” he added. Referring to some of the youths he had just met, he said: “We see ourselves in these young men. I grew up without a dad. I grew up lost sometimes and adrift, not having a sense of a clear path. The only difference between me and a lot of other young men in this neighborhood and all across the country is that I grew up in an environment that was a little more forgiving.”
Organizers said the new alliance already had financial pledges from companies like American Express, Deloitte, Discovery Communications and News Corporation. The money will be used to help companies address obstacles facing young black and Hispanic men, provide grants to programs for disadvantaged youths, and help communities aid their populations.
Joe Echevarria, a former chief executive of Deloitte, the accounting and consulting firm, will lead the alliance, and among those on its leadership team or advisory group are executives at PepsiCo, News Corporation, Sprint, BET and Prudential Group Insurance; former Secretary of State Colin L. Powell; Senator Cory Booker, Democrat of New Jersey; former Attorney General Eric H. Holder Jr.; the music star John Legend; the retired athletes Alonzo Mourning, Jerome Bettis and Shaquille O’Neal; and the mayors of Indianapolis, Sacramento and Philadelphia.
The alliance, while nominally independent of the White House, may face some of the same questions confronting former Secretary of State Hillary Rodham Clinton as she begins another presidential campaign. Some of those donating to the alliance may have interests in government action, and skeptics may wonder whether they are trying to curry favor with the president by contributing.
“The Obama administration will have no role in deciding how donations are screened and what criteria they’ll set at the alliance for donor policies, because it’s an entirely separate entity,” Josh Earnest, the White House press secretary, told reporters on Air Force One en route to New York. But he added, “I’m confident that the members of the board are well aware of the president’s commitment to transparency.”
The alliance was in the works before the disturbances last week after the death of Freddie Gray, the black man who suffered fatal injuries while in police custody in Baltimore, but it reflected the evolution of Mr. Obama’s presidency. For him, in a way, it is coming back to issues that animated him as a young community organizer and politician. It was his own struggle with race and identity, captured in his youthful memoir, “Dreams From My Father,” that stood him apart from other presidential aspirants.
But that was a side of him that he kept largely to himself through the first years of his presidency while he focused on other priorities like turning the economy around, expanding government-subsidized health care and avoiding electoral land mines en route to re-election.
After securing a second term, Mr. Obama appeared more emboldened. Just a month after his 2013 inauguration, he talked passionately about opportunity and race with a group of teenage boys in Chicago, a moment aides point to as perhaps the first time he had spoken about these issues in such a personal, powerful way as president. A few months later, he publicly lamented the death of Trayvon Martin, a black Florida teenager, saying that “could have been me 35 years ago.”
That case, along with public ruptures of anger over police shootings in Ferguson and elsewhere, have pushed the issue of race and law enforcement onto the public agenda. Aides said they imagined that with his presidency in its final stages, Mr. Obama might be thinking more about what comes next and causes he can advance as a private citizen.
That is not to say that his public discussion of these issues has been universally welcomed. Some conservatives said he had made matters worse by seeming in their view to blame police officers in some of the disputed cases.
“President Obama, when he was elected, could have been a unifying leader,” Senator Ted Cruz of Texas, a Republican candidate for president, said at a forum last week. “He has made decisions that I think have inflamed racial tensions.”
On the other side of the ideological spectrum, some liberal African-American activists have complained that Mr. Obama has not done enough to help downtrodden communities. While he is speaking out more, these critics argue, he has hardly used the power of the presidency to make the sort of radical change they say is necessary.
The line Mr. Obama has tried to straddle has been a serrated one. He condemns police brutality as he defends most officers as honorable. He condemns “criminals and thugs” who looted in Baltimore while expressing empathy with those trapped in a cycle of poverty and hopelessness.
In the Bronx on Monday, Mr. Obama bemoaned the death of Brian Moore, a plainclothes New York police officer who had died earlier in the day after being shot in the head Saturday on a Queens street. Most police officers are “good and honest and fair and care deeply about their communities,” even as they put their lives on the line, Mr. Obama said.
“Which is why in addressing the issues in Baltimore or Ferguson or New York, the point I made was that if we’re just looking at policing, we’re looking at it too narrowly,” he added. “If we ask the police to simply contain and control problems that we ourselves have been unwilling to invest and solve, that’s not fair to the communities, it’s not fair to the police.”
Moreover, if society writes off some people, he said, “that’s not the kind of country I want to live in; that’s not what America is about.”
His message to young men like Malachi Hernandez, who attends Boston Latin Academy in Massachusetts, is not to give up.
“I want you to know you matter,” he said. “You matter to us.”
Top News Chinas Intents Are Questioned as It Builds in Antarctica
HOBART, Tasmania — Few places seem out of reach for China’s leader, Xi Jinping, who has traveled from European capitals to obscure Pacific and Caribbean islands in pursuit of his nation’s strategic interests.
So perhaps it was not surprising when he turned up last fall in this city on the edge of the Southern Ocean to put down a long-distance marker in another faraway region, Antarctica, 2,000 miles south of this Australian port.
Standing on the deck of an icebreaker that ferries Chinese scientists from this last stop before the frozen continent, Mr. Xi pledged that China would continue to expand in one of the few places on earth that remain unexploited by humans.
He signed a five-year accord with the Australian government that allows Chinese vessels and, in the future, aircraft to resupply for fuel and food before heading south. That will help secure easier access to a region that is believed to have vast oil and mineral resources; huge quantities of high-protein sea life; and for times of possible future dire need, fresh water contained in icebergs.
It was not until 1985, about seven decades after Robert Scott and Roald Amundsen raced to the South Pole, that a team representing Beijing hoisted the Chinese flag over the nation’s first Antarctic research base, the Great Wall Station on King George Island.
But now China seems determined to catch up. As it has bolstered spending on Antarctic research, and as the early explorers, especially the United States and Australia, confront stagnant budgets, there is growing concern about its intentions.
China’s operations on the continent — it opened its fourth research station last year, chose a site for a fifth, and is investing in a second icebreaker and new ice-capable planes and helicopters — are already the fastest growing of the 52 signatories to the Antarctic Treaty. That gentlemen’s agreement reached in 1959 bans military activity on the continent and aims to preserve it as one of the world’s last wildernesses; a related pact prohibits mining.
But Mr. Xi’s visit was another sign that China is positioning itself to take advantage of the continent’s resource potential when the treaty expires in 2048 — or in the event that it is ripped up before, Chinese and Australian experts say.
“So far, our research is natural-science based, but we know there is more and more concern about resource security,” said Yang Huigen, director general of the Polar Research Institute of China, who accompanied Mr. Xi last November on his visit to Hobart and stood with him on the icebreaker, Xue Long, or Snow Dragon.
With that in mind, the polar institute recently opened a new division devoted to the study of resources, law, geopolitics and governance in Antarctica and the Arctic, Mr. Yang said.
Australia, a strategic ally of the United States that has strong economic relations with China, is watching China’s buildup in the Antarctic with a mix of gratitude — China’s presence offers support for Australia’s Antarctic science program, which is short of cash — and wariness.
“We should have no illusions about the deeper agenda — one that has not even been agreed to by Chinese scientists but is driven by Xi, and most likely his successors,” said Peter Jennings, executive director of the Australian Strategic Policy Institute and a former senior official in the Australian Department of Defense.
“This is part of a broader pattern of a mercantilist approach all around the world,” Mr. Jennings added. “A big driver of Chinese policy is to secure long-term energy supply and food supply.”
That approach was evident last month when a large Chinese agriculture enterprise announced an expansion of its fishing operations around Antarctica to catch more krill — small, protein-rich crustaceans that are abundant in Antarctic waters.
“The Antarctic is a treasure house for all human beings, and China should go there and share,” Liu Shenli, the chairman of the China National Agricultural Development Group, told China Daily, a state-owned newspaper. China would aim to fish up to two million tons of krill a year, he said, a substantial increase from what it currently harvests.
Because sovereignty over Antarctica is unclear, nations have sought to strengthen their claims over the ice-covered land by building research bases and naming geographic features. China’s fifth station will put it within reach of the six American facilities, and ahead of Australia’s three.
Chinese mappers have also given Chinese names to more than 300 sites, compared with the thousands of locations on the continent with English names.
In the unspoken competition for Antarctica’s future, scientific achievement can also translate into influence. Chinese scientists are driving to be the first to drill and recover an ice core containing tiny air bubbles that provide a record of climate change stretching as far back as 1.5 million years. It is an expensive and delicate effort at which others, including the European Union and Australia, have failed.
In a breakthrough a decade ago, European scientists extracted an ice core nearly two miles long that revealed 800,000 years of climate history. But finding an ice core going back further would allow scientists to examine a change in the earth’s climate cycles believed to have occurred 900,000 to 1.2 million years ago.
China is betting it has found the best location to drill, at an area called Dome A, or Dome Argus, the highest point on the East Antarctic Ice Sheet. Though it is considered one of the coldest places on the planet, with temperatures of 130 degrees below zero Fahrenheit, a Chinese expedition explored the area in 2005 and established a research station in 2009.
“The international community has drilled in lots of places, but no luck so far,” said Xiao Cunde, a member of the first party to reach the site and the deputy director of the Institute for Climate Change at the Chinese Academy of Meteorological Sciences. “We think at Dome A we will have a straight shot at the one-million-year ice core.”
Mr. Xiao said China had already begun drilling and hoped to find what scientists are looking for in four to five years.
To support its Antarctic aspirations, China is building a sophisticated $300 million icebreaker that is expected to be ready in a few years, said Xia Limin, deputy director of the Chinese Arctic and Antarctic Administration in Beijing. It has also bought a high-tech fixed-wing aircraft, outfitted in the United States, for taking sensitive scientific soundings from the ice.
China has chosen the site for its fifth research station at Inexpressible Island, named by a group of British explorers who were stranded at the desolate site in 1912 and survived the winter by excavating a small ice cave.
Mr. Xia said the inhospitable spot was ideal because China did not have a presence in that part of Antarctica, and because the rocky site did not have much snow, making it relatively cheap to build there.
Anne-Marie Brady, a professor of political science at the University of Canterbury in New Zealand and the author of a soon-to-be-released book, “China as a Polar Great Power,” said Chinese scientists also believed they had a good chance of finding mineral and energy resources near the site.
“China is playing a long game in Antarctica and keeping other states guessing about its true intentions and interests are part of its poker hand,” she said. But she noted that China’s interest in finding minerals was presented “loud and clear to domestic audiences” as the main reason it was investing in Antarctica.
Because commercial drilling is banned, estimates of energy and mineral resources in Antarctica rely on remote sensing data and comparisons with similar geological environments elsewhere, said Millard F. Coffin, executive director of the Institute for Marine and Antarctic Studies in Hobart.
But the difficulty of extraction in such severe conditions and uncertainty about future commodity prices make it unlikely that China or any country would defy the ban on mining anytime soon.
Tourism, however, is already booming. Travelers from China are still a relatively small contingent in the Antarctic compared with the more than 13,000 Americans who visited in 2013, and as yet there are no licensed Chinese tour operators.
But that is about to change, said Anthony Bergin, deputy director of the Australian Strategic Policy Institute. “I understand very soon there will be Chinese tourists on Chinese vessels with all-Chinese crew in the Antarctic,” he said.
