Installation of CCTV Security Cameras

With the noteworthy rise in number of crimes in the society, security has become the major concern of everyone. Due to which the demand of security solutions like CCTV cameras or security monitoring devices has exaggerated from last few years. It is not limited only to big companies or offices, but people are opting for CCTV/ security cameras for their homes,shops,storage area and government is also using them at public places, local buses  etc.
Now, coming to the actual purpose, How to avoid the extravagant installation cost?
The answer to this you will find in later part.
There are few steps, to help the successful installation of your CCTV cameras.
1.  Select the camera and monitoring equipments- as plenty of options are available in the market for selecting the CCTV /security cameras with multi specializations, like you have different lenses for daylight and darker areas. Then next consideration is about the clarity of video provided by camera.Likewise, there is many options available to select from.Next, is to buy the monitoring devices for watching the recorded video. You could choose from television to be used as monitor or a separate LCD for reviewing footage.
2. Placement of camera: after purchasing the appropriate equipments, next comes the time to look for places where you want to establish the cameras.
NOTE: cover your all entrances including main door, subways, garage doors; basements etc .other thing to check is keep safeguard from possible vandals.
3. Wiring: Now you have to decide about the route you to built like either from attic or basement.
But more efficient option is of attic because of its easy accessibility for drilling holes.
This phase is most tedious of all as it takes lot of time and efforts. Try to obtain the minimum cable lengths and prominent video quality.
NOTE: Don’t compromise on the quality of the cable, as this is to be used for long time.
You can rely on RG59U with power Coleman cable (YES it is US made) sometimes called Siamese type cable
Now, bring the cable to the first camera location and mark it as ‘X’and drills the hole by using a1/2 inch or smaller drill. Pull cable of about 10-14 inches from the hole made and move towards the backend of your system. Once you reach at the backend, pull out another 2 feet of your cable, which is enough to reach the power supply and DVR with the leftover length and cut them off.And, don’t forget to label this part.So,finally you have placed your cables .
4.  Mounting camera enclosures:  As you have finished of setting up of cables, it’s time for mounting camera enclosures.Go,at the place of the CCTV cameras and mount it accordingly along with leaving ample spaces for it’s easy movement to up-down, left-right. Opt. for drilling of pilot holes while mounting your enclosure arm.
After the mounting of enclosures, feed the cables safely at the back of the enclosure.
5. Screwing camera: take out camera and lens from the box and uncover them carefully.Now, screw them together but keep the lens cable loose and plug it into the back of the camera. Make sure that you are facing the camera’s back and ‘lens’ switch is set to ‘video’ not to ‘DC’.Time for mounting cameras on the enclosures. Slide out the camera rig and mount bottom of camera to slide via screw in enclosure packing. Slowly slide the camera towards enclosure. Add the ends to your cables. Make the BNC connection with crimp on BNC connector and your pins of BNC crimps.
To start with take barrel part of connector, with wide side at top slide it on cable. With wire cutters, cut about 3/4 inch of the outer casing, leaving only the center copper wire and protector. Then use wire cutters to cut, about 1/2 inch of the copper wire casing, leaving the bare copper wire. Shear the copper wire at an angle and slide BNC over the exposed copper. Then pull the barrel up of the RG59 cable, over the end of the BNC connector and use your crimps for crimping them together. Don’t connect this to the camera yet.
6.   Setting DVR:  Drag the DVR out of package and position it where it belongs to. It’s time to braid our power wire and feed it into the power supply. When you are connecting your power wire, make sure to keep (+) and ground wires uniform with their corresponding camera. Positively, make sure your power supply is not on.
7.  Focusing camera: As our power is connected both at the back-end and camera. Move ahead and plug power supply into the wall. Check out for left over piece of RG59, of 3-6 feet, and throw BNC ends on both sides. This will plug in out LCD monitor and back of the camera, so you could focus it. With the small thumb screws over the lens, adjust the focus of the lens, but be patient while adjusting because it may take few minutes. Once, you got it accurate, tighten the screws and pull back the BNC wire.
Put down, portable monitor for a second and plug designated BNC connector into the camera. Close and lock the enclose, ensure all excess wire is either zip ties to the frame or snug away in the wall.
8. Final step: Plug your BNC cables into the back of the DVR. Get an extra piece of the coaxial cable and join BNC ends to it. . Be certain about that extra piece of cable is long enough to reach from DVR to the LCD monitor to be used for reviewing footage. Once making that connection, plug one end into “out” on the DVR. Other ends require your BNC-to-RCA adapter, and then join the RCA into your LCD monitor. Connect your DVR and LCD monitor into the wall and switch on power.
At last, we are almost over with installation, just to be on safe side, review your connections and power supply along with setting of your monitoring device.
