In order to set up a Video Security System which works smoothly, the wires and cables play crucial roles. They help connect between the camera and the power source. They are also the video signal bridge between the camera and the DVR. However, choosing and setting up these components are not an easy task. There are many things to pay attention to in order to make sure the system works well. You should also read the security camera systems reviews to purchase the best one.
First of all, you must have a good understandings of your camera security system. Are they analog or digital?
Secondly, the camera is connected to a nearby power source or remotely? In case remotely connected, the video and power cables should be run together. In other words, you will need the Siamese Cables or a special cable which combines two of them. With these particular cable, the installation process will become much easier.
One rule of thumb is before you set up the camera, I highly recommend you to check the camera cable. You connect the camera with the power source and with the DVR via this cable for this task. You should also test the pre-made cables. Caution is never be an excess. It can keep you stay away from headaches during the installation process.
Pre-Made Cables Wiring Tutorial
- As we all know, a cable has 2 ends. The cable is used for connecting the camera and DVR. There’s a male power connector on the camera. That’s why the end with the female connector is right for the camera. The rest is for the DVR.
- Link the power source and the video to the camera pigtail.
- Now, it’s the time to use the BNC cable for connecting the DVR via the video connector.
- Connect the power source with the power cable. It depends on which type the camera is, there will be two possible cases – a power source vs multi-camera splitter or some power supplies or each source is connected to a camera.
What the camera sees will be broadcasted to the live screen on the DVR.
Some further information regarding to the video cable and its maximum length
The quality of the camera has nothing to do with the distance between it and the recorder. This is the problem of the cable connecting them. The professionals prefer the coax cable for this task. A RG59 coax cable can have a length of 600 feet. RG6 can even have longer length – 1000 feet! The length of a camera cable can be up to 500’ boxes. The pre-made cables can be long up to 100’ boxes.
How to wire the Bulk Cable and choose the appropriate cable length
- Choose the appropriate length of the BNC cable and cut it from the box.
- Take the BNC cable and make 2 ends of this cable fitting. After finishing this task, connect one of the end to the camera and the other one to the DVR.
- At the end of the power cable which is for the camera, remove the outer shielding in order to see the black and the red wires inside. Remove around a quarter of inch of each wire jacket.
- Connect the power cable to the power source pigtail. The red with the red. The black with the black. Then, use a screwdriver to make the screws on the terminal tighter. Then, put the camera into the fitting located at the end of the pigtail.
- At the end of the power cable which is for the DVR, remove the outer shielding in order to see the black and the red wires inside. Remove around a quarter of inch of each wire jacket.
- In case you have a multi-camera power source, the wire should be connected directly to the power box leads. The red wire is attached to the Positive and the black is for Negative.
- In case you have a single camera power source, use the pigtail instead.
Make BNC Cable Fitting Guide
- Remove around 0.5’’ the cable shield in order to see the center conductor
- Remove 0.25’’ of black covering in order to see the shielding. Prevent the copper shielding from touching the center conductor
- Plug the cable into the fitting. Be careful of the center conductor, due to the absence of the shield and the black cover, it is quite fragile now. Now find the hole of the fitting before plugging.
- Turn the fitting around in a circle with your hand on the wire and simultaneously put a slight pressure on it until they are firmly connected to each other.
