CCTV

CCTV
A Closed-circuit television (CCTV), widely known as video surveillance, refers to video cameras’ use to transmit signals with a limited set of cameras to a specific limited number of televisions on the same circuit network.
How the CCTV works.

CCTV has several inbuilt cameras. The camera itself has an open aperture that captures the light stream through the lens. The light stream is then channeled to a digital chip inside the camera and then turned into a sequence of images. The images are then transmitted in the form of a signal either wirelessly or by a cable to the recording device.

Is the use of CCTV legal?

The usage of CCTVs is legal when it complies with the law’s guidelines or terms and conditions. According to the government, if a person decides to install a CCTV in his/her business premises, he/she must inform the public that they are being recorded. In this case, it also has to have appropriate signage.
On the other hand, if a person decides to set up a CCTV in his/her home premises of property, he/she does not require permission from anyone, but the person should inform the neighbors. And if you do not own that property, you should first talk and gain approval from the landlord.

How the CCTV is installed.

Below are six simple steps that will guide you in installing your CCTV camera.

  1. Choosing the right spots for your CCTV camera.
    The selection of favorable spots is the most crucial step of installing your CCTV. You must ensure that the location you have chosen maximizes camera coverage and also minimizes the length of the cable used. For indoors, it’s advised that you select a corner from where most of the entry points are visible, and for an outdoor camera, choose a higher spot that covers all the entry points, the door, garage, and windows.
  1. Mounting the camera.
    The second step involves the process of mounting the cameras. This process involves;
    i. Placing the camera unit at a desirable place, marking guide marks for drilling.
    ii. Drilling the holes and hammering in the screw moldings.
    iii. Screwing the camera firmly into place.
    iv. Inserting the power cable of the camera in a socket.
  1. Placing the DVR.
    A DVR refers to the hard disk that stores all the recordings of the CCTV cameras. Therefore it should be placed in a highly secure place that is out of reach from anyone but yourself.
  1. Management of the Camera cables.
    This step starts with marking the pathways for your camera cables from the Security cameras to the DVR. You should ensure that those pathways are safe and manageable before nailing those cables into place.
  1. Connection of the wires.
    It’s critical to note that the video cables are connected using a BNC port; hence, you should remove 1.5 centimeters of the lines’ outer coverings, thus exposing the braids after telling them to slide the crimping barrel onto the cable. After this, you will remove the white insulator, which covers the innermost line, then insert those exposed cables into the BNC port then screw the crimping barrel. After completion of the above steps, connect the DVR output port to your chosen screen.
  2. The last step involves powering the whole system starting with the cameras, followed by the display, and then lastly, the DVR. Confirm that each camera has a desirable angle and is working correctly.

The importance of installing a CCTV.
There are numerous advantages of CCTV installation. Some of those advantages include:

  1. A CCTV acts as a force for law enforcement.
    The installation of a CCTV repays in the collection of evidence whenever a crime happens in your premises. The CCTV helps the raw enforcers place locations, times, suspects, and places where the crime occurred hence solving the crimes far more quickly. It’s also crucial to note that the CCTV can be used as evidence in the court of law in crime commitment scenarios.
  2. It encourages work productivity by monitoring the activity of the workers.
    The installation of CCTVs will help eradicate workers’ laziness during the working hours, thus increasing work productivity.
  3. It can be used in monitoring the safety of people.
    For example, a CCTV can be installed to help monitor workers working in a dangerous environment. It can sometimes be used to track lost people, especially young children.
  4. It helps deter crime.
    A CCTV infers an air of danger to a person planning to commit a crime or presence of the law. Thus, installing CCTVs, baggers, and thieves’ fear of being seen by the owners prevents crimes.
  5. Decision Making.
    Whenever one is solving disputes in domestic or commercial scenarios, the CCTV footage is crucial. With this evidence, you will know the truth of what happened in that particular place.
  6. It helps to keep records.
    The CCTV footage is significant, especially on a commercial premise. It helps record when the staff reports at work or leaves the premises, when deliveries are made, and when visitors enter and exit the building. This information plays a significant role in ensuring that the business runs smoothly.
    The cost of CCTV installation at home.
    The cost of installing a CCTV generally differs depending on the number of cameras, the quality of the CCTVs, the distance to be covered (the compound’s length, and the number of houses).
