cctv camera - do-it-yourself installation guide - cctv camera case
Brief: This guide is written for people who do need video security and can't afford expensive installation services, or if there is no CCTV installer in your area
The latter is more common than people think.
We will cover the most common types of security devices, as it is almost impossible to browse through such a wide range of different security cameras and recording/video processing devices on the market.
I think anyone who thinks about doing thisit-
I have basic knowledge of wiring technology and practice for CCTV installation.
I am not responsible for equipment damage due to improper handling or misuse. Remember;
Be sure to pay attention to safety during installation.
Working and using tools at high places can be dangerous, please follow all safety measures.
Now let's jump straight to it.
Planning: The first step in any camera installation is to plan the location of the camera and the monitoring device.
When planning the position of the camera, please consider the light condition, do not install the camera in the room with insufficient light, direct to the sunny area, this will add glare to the picture, this is not enough even if your camera has backlight compensation.
Use an infrared camera and/or a B/W camera with the lowest possible number of Lux in very dark conditions.
I am not going to discuss the right device options as this is the subject of my previous article.
It is not easy to choose the best camera position, and it will directly affect the camera's perspective.
In addition to the light conditions, the distance from the monitoring object is equally important.
There are many types of lenses and focal lengths;
Your selection will depend on the light condition and the distance from the camera to the monitoring object.
In a small room about 500sq. ft.
Standard 3 camera.
6mm lens should be OK.
Keep in mind that most bullets and board-type cameras come with 3.
6mm lens, the greater the distance to the monitoring object, the longer the lens focal length is required.
There is no easy way to judge lens selection, you can guess or buy a professional lens selection tool. .
Alternatively, you can start with your lens selection and get a longer or shorter focal length lens later if needed.
As far as lens selection is concerned, the other option is to use a variable focal length lens, which is a very general method that can be guessed from the lens selection process.
For those who don't know what a variable focal length lens is, it's basically an adjustable focal length lens that can change the focal length within a specified range, for example: 2. 6mm -8mm or 5mm -50mm.
In order to maximize the coverage of the camera and get the maximum benefit from the CCTV system for the least amount of money, unless complete area coverage is required, put the camera in a strategic position
Avoid overlapping camera views, do not install them directly in front of the light source, and do not point infrared cameras to each other to eliminate the risk of over-exposure.
These are the most common mistakes that need to be avoided.
After booking the initial camera position, let's take a look at the location of the cable.
Make sure it is actually possible and practical to connect the cable to each location, if connecting the cable to any camera location is not selectable for some reason
Go to another place.
Wiring: the most time-consuming and important part of any camera installation is wiring.
Carefully Plan your installation to minimize the length of the cable and ensure the quality of the video signal.
Do not run the cable next to the high power cord, it is recommended that there be at least 12 "spacing between the video cable and the power cord.
Most people take the cable for granted, but it is actually a very important aspect of any installation.
CCTV's system is only the weakest part.
I usually use the power Coleman Cable (
Yes, we did it)
It is sometimes called Siam cable.
It is a combination cable that will transmit video and power as an alternative, sometimes using RG6 standard coaxial cable with a lower price, and the Power operates separately as a 18/2 ad hoc working group.
The Siam cable is small in size and it is easier to run, and it is recommended to use this cable as the power supply will be powered from public places next to the monitoring and recording equipment.
Since only one line is needed for each camera, the use of Siam cables can make the installation cleaner and cleaner.
If there is a power outlet near each location, running the RG6 cable with a separate running power supply may be the solution.
In this case, they are powered using separate power plugs, and the power cord operates as a line independent of the camera.
Dvrexperts provide both types of cables.
When running the cable, it is better to leave a few extra cables in the camera and monitoring position.
Additional cable lengths are required if it must be moved slightly in future monitoring or location.
Labor after the cable is in place-
The intensive part of the installation is over and now we can go to the interesting part of the installation.
Camera installation: Most s come with mounting screws and brackets, securely attach the brackets, and keep in mind that in some cases it may be necessary to be different from the one that comes with the holder on the camera.
Attach the camera to the stand and adjust the position around this time and we will come back later.
The typical security camera is powered by 12VDC or 24VAC and the power input type is screw or push head terminals or 2. 1mm plug.
The power connection for each power supply and input mode will vary.
Most cameras are 12VDC and it is important to observe polarity in this case, otherwise it may damage the camera.
The power cable has two conductors and in most cases it will be a red or white and black cable.
Use red or white on the front and black on the negative.
If there is a screw or push the terminal power input, if it is 2, directly connect the cable to observe the polarity.
1mm plug, Special 2.
1mm the parent DC plug with the flight lead must be connected to the cable again, please note the polarity.
The 24VAC connection is very similar and there is a major difference --
Polarity is not important.
The next step will involve some special tools and accessories.
We will try to see the installation process of the BNC curl-
On the video connector, I will be releasing a video demo of the BNC Curl technology soon, so please check the website mentioned in this article frequently. Steps: 1.
About 1/2 removed-
An inch long coat with pigtails exposed from the end of the video cable. 2.
Slide the cord bucket into the larger diameter cable. 3.
Pull the weave back to reveal the inner isolating material and remove 3/8-
So you have exposed the core conductor now. 4.
There is a small hole on one side of the main part of the Connector;
Push the exposed core conductor of the cable into the hole. 5.
Push all the braids folded in step 3 back onto the BNC connector and evenly distribute the braids around the connector. 6.
Push the cord bucket all the way to the BNC connector. 7.
Use the press line tool to squeeze the press line barrel onto the BNC connector, and now the cable weaving is compressed between the press line barrel and the BNC connector to ensure a secure connection.
The BNC connector is On, Let's connect it now, and if you have purchased 16 camera systems, you may want to have some coffee first, please repeat the steps for each camera.
Monitor and recorder connection: The camera is on and it's time to make the final connection.
I will focus on standard CCTV monitors, stand-alone DVR recorders and power distribution as this is the most popular and possible solution for most CCTV installations.
First of all, we also have to install the BNC connector on this side
It's time to have another coffee.
Now it's a good idea to make room for the display and recorder and set up some type of table, shelf or shelf to place all the equipment.
In order to determine the appropriate power position, we need to install the monitor and the recorder.
The power supply should be installed within a few feet of the DVR video input.
After the power supply is fixed, separate the power conductor from the Siam cable and connect it to the power supply.
As we do with the camera when using the 12VDC power supply, we need to observe the polarity, each terminal on the power supply is marked, so there should be no doubt.
Make sure the power supply is not plugged into the power outlet yet.
Connect the video cable to the DVR video in the port.
We need a video cable to connect the DVR to the monitor, if you don't, you can cut off a piece of Siam cable, separate the power conductor from the monitor and install the BNC connector on both ends, you have the cable now.
Connect the DVR monitor output port to the monitor video input.
We are almost ready.
There is only one thing to pay attention to before we do so.
We need to protect the device from power spikes by plugging it into a power regulator or better backup.
If there is a frequent power outage at the installation location, it is strongly recommended to use the spare equipment.
To extend the backup time, simply plug the DVR and camera power into the backup unit, plug the monitor into the regular power strip, so that if we lose power over a period of time, the DVR and the camera are still working properly when the monitor is turned off.
Turning off the display will not affect the DVR and the camera in any way;
If not used to extending its life, it is actually a good habit to turn the monitor on.
Boot and final adjustment: Yes. . .
We are now ready to power it up for the first time, and if this is your first installation, it could be nerve --
Start by turning on the camera power, turn on the monitor, and then the DVR system. The stand-
DVR after independence
Depending on your model, the test will display the camera or settings menu on the first power-on.
To set up the DVR, please refer to the manual for the correct settings.
Check each camera view to determine if the view is really what you want, and it's almost never the case if there's no extra adjustment.
In order to adjust the position correctly and easily, it will be very convenient to test the monitor if it is not an essential tool.
If satisfied, please go to each camera location and connect the test monitor to adjust the location according to your preference
We won't be back in front of this.
You have just completed the most likely first installation of the CCTV system.
