Memilih CCTV

Memilih CCTV 

Memilih Kamera CCTV sering kali membingungkan bagi orang yang awam akan produk ini. Hal ini disebabkan karena produk Kamera CCTV yang beredar di pasaran sangat bervariasi dalam merk, jenis, harga, teknologi, dan kualitas. Kurangnya standarisasi dalam fitur / teknologi yang terdapat dalam Kamera CCTV juga menyulitkan calon pembeli untuk membandingkan produk satu dengan lainnya. Artikel ini mencoba memaparkan secara sekilas aspek – aspek yang membedakan kamera satu dengan lainnya sehingga dapat digunakan sebagai referensi awal dalam pemilihan Kamera CCTV.

Kamera CCTV dapat dibedakan berdasarkan jenis output, lokasi penempatan, waktu penggunaan, mekanisme control, dan resolusi. Mengacu pada jenis output, Kamera CCTV dapat digolongkan menjadi Analog dan Digital.

• Camera CCTV Analog yaitu kamera yang mengirimkan continuous streaming videomelalui Kabel Coaxial

• Camera CCTV Digital yaitu kamera yang  mengirimkan discrete streaming videomelalui Kabel UTP. Camera CCTV Digital umumnya dilengkapi dengan IP Address sehingga sering pula dikenal sebagai IP (Network) Camera. Dengan adanya IP, kamera bisa dapat langsung diakses melalui jaringan LAN/WAN tanpa harus menggunakan tambahan converter.

Berdasarkan lokasi penempatan, Kamera CCTV dapat dibedakan menjadi indoor dan outdoor camera.

• Indoor Camera Jika pemakaian utk indoor saja, pilihannya menjadi semakin banyak, sebagian besar camera yg tersedia digunakan utk indoor. Sesuaikan dengan bentuk fisik camera yg diinginkan dan penempatannya, entah itu di plafon, tembok/dinding, disembunyikan atau tersamar dgn produk lain mis: smoke detector camera.Indoor camera juga ada yg dilengkapi infrared yg berguna utk memantau pada kegelapan, namun jika ruang/area yg dipantau cukup terang setiap saat, cukup memilih yg non infra saja.
  Dome camera khusus dipasang pada plafon/langit-langit dan tidak bisa digabungkan dgn rotator, dikarenakan tidak tersedia dudukan utk rotator, jika ingin ber-type Dome dan dapat berputar pilih Pan Tilt Dome Camera saja, sedangkan diluar type Dome bebas saja penempatannya, dapat dipasang pada plafon maupun tembok/dinding dan juga bisa dipasangi rotator.
  BOX camera mempunyai kelebihan pada lensa yg dapat diganti dan disesuaikan dgn kebutuhan, tersedia beberapa pilihan ukuran lensa yg dijual secara terpisah. Semakin kecil ukurannya semakin lebar view anglenya, dan semakin besar ukuran milimeternya semakin sempit view anglenya namun lebih zoom, atau agar praktis dapat memeilih Lensa Varifocal yg tersedia.
  Camera berdimensi kecil unggul jika pada penempatannya ingin disembunyikan, namun camera berdimensi besar juga mempunyai keunggulan tersendiri yaitu camera dapat terlihat dgn jelas, sehingga sering kali hal ini merupakan momok yg cukup menakutkan para pelaku tindak kejahatan, karena area tersebut jelas-jelas terlihat diawasi dgn cctv camera.
• Outdoor Camera Jika pemakaian utk diluar ruangan/outdoor, pilih camera yg khusus utk outdoor juga. Bedanya dari camera indoor adalah, camera outdoor lebih mampu mereduksi cahaya matahari dan jumlah LED infrared yg dipakai umumnya lebih banyak dibanding yg ber-type indoor. Semua camera outdoor yg tersedia sudah weatherproof (IP66 / IP67) dan dilengkapi Pelindung utk menahan sinar matahari maupun air hujan atau biasa disebut topi, dan tidak perlu membeli housing lagi.

Waktu Penggunaan merupakan faktor yang penting diperhatikan saat memilih Kamera CCTV. Kemampuan Kamera CCTV untuk dapat menangkap gambar pada pencahayaan minimum dinyatakan sebagai minimum lux, yaitu minimum satuan cahaya (lux) yang diperlukan Kamera CCTV agar dapat menangkap obyek. Secara umum terdapat 2 jenis kamera cctv berdasarkan waktu penggunaan (minimum lux):

• Standard Day Camera CCTV yaitu kamera yang digunakan untuk memonitor ruang yang memiliki tingkat penerangan cukup baik secara konsisten (di atas 0.5 lux)
• Day-Night Camera CCTV yaitu kamera yang digunakan untuk memonitor ruang yang memiliki tingkat penerangan kurang (di bawah 0.5 lux terus menerus ataupun sebagian waktu)

Mekanisme control pada kamera cctv memungkinkan pengguna menggerakkan sudut pandang kamera secara vertical, horizontal, maupun mengatur jarak pandang (focus). Berdasarkan mekanisme kontrol ini kamera dapat dibagi menjadi:

• Motorized Camera CCTV yaitu kamera yang dilengkapi dengan motor untuk menggerakan sudut pandang ataupun focus secara remote. Motorized kamera meliputi beberapa jenis kamera seperti: zoom camera dan speed dome camera
• Fixed Camera CCTV yaitu kamera yang sudut pandang dan fokusnya harus disetting secara manual pada saat instalasi.

Faktor lain yang juga sangat penting dalam menentukan kamera cctv adalah resolusi kamera. Resolusi ini dinyatakan dalam jumlah TV Lines (TVL), semakin besar jumlah TVL maka akan semakin tinggi resolusi kamera yang bersangkutan. Kamera yang memiliki resolusi yang semakin tinggi akan menghasilkan gambar yang semakin tajam. Namun kamera beresolusi tinggi juga membutuhkan monitor dengan resolusi tinggi untuk dapat menampilkan gambar yang ditangkap oleh kamera secara utuh. Berdasarkan resolusinya kamera dapat dibedakan menjadi 3 jenis:

• High Resolution: kamera yang memiliki resolusi di atas 480 TVL
• Standard Resolution: kamera yang memiliki resolusi 380 – 480 TVL
• Low Resolution: kamera yang memiliki resolusi dibawah 380 TVL

Semua faktor tersebut di atas akan mempengaruhi jenis kamera cctv secara fungsional, di samping faktor di atas terdapat pula faktor lain yang juga sangat mempengaruhi kualitas Kamera CCTV seperti Jenis Images Sensor dan Jenis Arsitektur Chipset. Jenis Image Sensor yang banyak digunakan saat ini adalah CCD dan CMOS, sedangkan jenis arsitektur chipset yang banyak digunakan pada Kamera CCTV adalah chipset Sony, Sharp, dan Panasonic.
