Analog Security Camera Installation at Home

Analog Security Camera installation at Home


Home security camera (system) installation issues keep popping up, while you are choosing top surveillance equipment. Drilling holes, running wires and cables inside and outside an apartment may freak you out. Not to mention, the CCTV security camera (system) installation cost in US, Australia, Canada, India, etc. if you ask for professional home surveillance companies, installers, or other video camera installation services.

Hi Indian, no worries. Take a coffee break, and follow the expert instructions below on installing wired and wireless home security cameras inside and outside of your sweet home.
Most home surveillance packages come with the wires, DVR, and cameras included, and are a much easier way to start your system then buying everything separately.

To install a security camera system for your house, start by surveying the layout of your home and assessing how many cameras you’ll need. Once you purchase the system, install the cameras high up on the walls so that they have a broad frame in the shot. Most cameras mount to the walls with screws, and can be plugged into a regular outlet. Connect wired cameras to the monitoring system using BNC cables, or link wireless cameras to your computer.

Buy the right package to suit your needs. You can buy each piece individually, but it is generally cheaper and easier to buy bundled security systems. At a minimum your system should have 1-3 cameras, a DVR (digital video recorder), appropriate wiring (3+1 Cable / RG and BNC cables), and power cords. Unless you are choosing to monitor a large area, wireless cameras with wall mounting should cover your needs.

Basic Home Security: Get a package with 2-3 outdoor cameras (to monitor doors), and a DVR with at least 3 days of recording time.

Make a diagram of your surveillance needs. It is both expensive and inefficient to monitor every square inch of your house, so you need to prioritize what areas you want to watch the most. Draw up a rough diagram of your house or print out the blueprints and note where you might want to place cameras. When you are done, check out each location to make sure it is not blocked by anything and provides the best view possible. You may want cameras for:
·        Front and back doors.
·        Off-Street Windows
·        Large common spaces (kitchen, living room etc.)
·        Driveways
·        Porches
·        Stairways

Choose a high, broad angle for your camera. The best angle of any room is usually looking down from the corner where the ceiling meets the walls. Make sure you can clearly see all entries and exits and that the camera is near a power outlet.
If you are mounting a camera outside, place it above 10ft so that it cannot be easily knocked down. Mount your camera to the wall. Some cameras come with sticky pads to adhere your camera to the wall, but screwing your camera in is the safest way to mount your cameras long-term. While every camera is different, most of them can be mounted the same way:
  • ·        Place the mount in its desired location.
  • ·        Using a sharpie, make marks on the wall where each screw should go.
  • ·        Drill a hole for each screw using an electric drill
  • ·        Hammer in any molding pins.
  • ·        Screw the mount into the wall.
  • ·        Position the camera to your desired angle.

Attach your camera to a power source. Almost all cameras come with a power adapter that plugs into a normal wall socket. Plug the small, round end into the power input on the back of the camera and plug the other end into the outlet.
Use a power supply box to power multiple cameras through one outlet. Power boxes, available online and in hardware stores for Rs.200-Rs.400, allow you to power your cameras through a single wall outlet. They come with multiple ports and are great for powering close-together cameras or cameras that aren't near an outlet, like attic cameras. However, you will need to run lengthy amounts of wire to attach each camera to the same box.
·        Always attach the cameras before hooking the box to electricity.
·        Make sure you buy a power supply box big enough to power each one of your cameras. They should list how many outlets they support on the box.
If your power adapter is missing or broken, contact your manufacturer.

Now the most important part is Cable. In Security camera cable is basically manufactured in such a way that it should optimize video signal quality. CCTV camera cable is composed of two sub cables that will run simultaneously for transmitting both video and power signal, Video transmitting cable also called RJ59 Cable, one sub cable is the central solid copper conductor core shielded by dielectric material, then further shielded by copper or alloy braid that will transmit video signal and another is power cables that will transmit power and both two-part is insulated by PVC having diameter of 5.5 mm to 7.5 mm.

Now I would like to explain core means RJ59 cable, which is made up of dense copper having diameter of 0.22 to 0.28 mm. this core is very crucial and play a vital role for CCTV integrator. If use cable which have good quality solid copper which have more than 0.25mm diameter and have more than 30 shielded braid then definitely you can transmit video up to 150 meter but you should keep in mind that for 150 meter Video transmission you should also transmit power for 150 meter, for this you need good quality AWG power cable. In India this type of cable is very rare you have to make on order. General Cables comes in Indian market have 0.22mm diameter core that will transmit up to 90 meters only.  As far as security camera cable wire color code is considered generally yellow wire is used for video, Red color power wire is used for positive (+), Black color wire is used for Negative(+) and green is for ground. BNC Connector is connected to yellow wire and DC connector is connected to red and black color.
There is 3 type of security camera cable which as is as follows.
·        4+1  CCTV Cable – This Cable is the composition of two type sub cable that will run simultaneously one part is four power cables that will transmit Power and another part is the RJ59 cable that will transmit video.
·        3+1  CCTV Cable – This Cable is the composition of two type sub cable that will run simultaneously one part is three power cables that will transmit Power and another part is the RJ59 cable that will transmit video.
·        2+1  CCTV Cable – This Cable is the composition of two type sub cable that will run simultaneously one part is two power cables that will transmit Power and another part is the RJ59 cable that will transmit video.
Note:
Maximum length for coaxial cable for CCTV is 300 meters of CCTV Cable without any joint but it will transmit video only up to 100 meters.

Hide your wires. To have a truly professional looking system you can run your cables through the walls and towards your surveillance hub. Be sure you know the layout of your walls and the location of any pipes, cables, or studs as you begin running wires. Running cables requires you to drill a hole in the wall, then thread the cable through the walls to your DVR through open spaces in your house, usually the attic.
·        If you are not comfortable drilling into your walls and running cables through, call a professional carpenter or handyman to take care of the cabling.
·        You can also secure cables to the walls or baseboards using a staple gun.
·        Consider hiding cables under rugs, but tape them down so that no one accidentally trips.

Attach a wired camera to your DVR. Surveillance equipment is connected using a BNC (Bayonet Neill–Concelman) connection.
BNC cables are simple to use -- they are identical on both sides and you simply plug them into the appropriate port, turning a small nut on the end to lock it in place. Plug one end into your camera's "Output" and the other into one of the DVR "Input" ports.
·        Note which input you plug into -- this is the input your DVR must be set to in order to view your camera's video.
·        If your cable does not have a BNC connection you can buy a simple BNC adapter online or at a hardware store. This will slip onto the end of your cable to make it BNC compatible.
Attach the monitor to the DVR. This connection frequently uses a BNC cable as well, but some DVR's can attach with HDMI cables or coaxial cables. Using your preferred connection, attach one end to the DVR's "Output" port and the other to the monitor's "Input."
·        You can hook up as many cameras as your DVR has inputs -- it will automatically record every camera you install.
·        Note which input you plug into-- this is the input you need to choose to see your cameras.

Create a central "surveillance hub." When you are wiring a lot of cameras at once, you'll need one simple place to bring all of the feeds together to your DVR. This should be a place that is easy to access, and where you can comfortably run wires from anywhere in the house. Attics, offices and your internet router all make good places to base your surveillance system.
You should only need one DVR for all of your cameras. Attach each video cable to a separate DVR port. Your DVR can handle multiple cameras at once, allowing you to record every room in the house with only one box. Your monitor will then display every camera, or you will have to cycle through them using the "input" button on your DVR.

Guidelines for outdoor security camera placement
  • Install cameras 8-10 feet from the ground. This height is low enough to capture fine details but high enough to be out of easy reach of thieves and vandals.
  • Don’t point cameras directly at the sun. Bright light causes glare and high contrast in your footage, which makes it hard to tell what’s going on. Consider the movement of the sun and angle your cameras for indirect light.
  • Decide whether you want the camera to be visible or hidden. Visible security cameras are effective burglary deterrents, but they are also targets for theft and vandalism. Some homeowners choose to prominently install a fake decoy camera and back it up with a real one that’s slightly more concealed, while others add heavy-duty hardware or casing around the camera to make it more difficult to damage.  
  • Protect the camera from the elements. Top outdoor security cameras have ample weather- and waterproofing, but they are not all created equal. Choose a camera that’s appropriately rated for your climate, and place it under eaves or in another semi-protected area if you can.


Guidelines for indoor security placement
  • Corners are your friends. Hanging an indoor camera in the corner of a room usually gives you the largest possible vantage point.
  • Windows can cause reflection issues. Pointing a camera out the window might degrade its image quality. Many security cameras have infrared (IR) light technology, which aids in motion detection and enables the cameras to function in low light. IR light can reflect off of windows and other glass objects and obscure your footage, especially in the dark. If your footage looks washed out or whited out, there is likely a reflection problem going on.
  • If it’s necessary to point a camera out the window, positioning the lens as close as possible to the glass and/or backlighting the outdoor area (perhaps with motion detector lights) are two glare-minimizing measures to try. It can also be helpful if your camera has wide dynamic range (WDR) technology.
  • Angle for indirect light. Again, direct light will wash out your footage. With indoor cameras, be mindful of lamps, light fixtures and bright windows. Avoid facing your camera directly toward any of these light sources.


Attention: Don’t be cheated by some cheap wired security camera systems with DVR, which use old analog cameras, and record fuzzy and useless videos. Some other wired CCTV DVR security camera systems may have more functions and cost you over Rs. 12500, almost the price of a quality NVR wired security camera system with improved performance on all rounds.

Anyway, the wired security camera with DVR is by no means a futurist choice, if it is not outdated.
