Being dealers of all types of security cameras it is not possible to cover all the various types of camera systems and each process of installation, however we will cover the steps carried out to set-up a analog system. Analog technology has been around for a long time now and is considered one of the most secure systems.  The newer systems of today do have a few variations, however the installation type is very similar to the analog interface. The following equipment is a must for a successful installation; DVR (Digital Video Recorder), Security Cameras, Power Supply, Cabling, Connectors and Siamese connections.

Digital Video Recorder

A digital video recorder is used to transmit signals from the surveillance cameras to capture and record video feed. DVR’s are available in multiple configurations that allow different number of cameras to be attached to it. A standard DVR is available to attach upto 4 cameras, other configurations are available in 8,16 and 32 channel DVR’s. 8 channel DVR’s are mostly recommended by most CCTV camera dealers in Goa which are suitable for villas and small apartment complexes. Additionally, the DVR would also require a hard drive to be installed in the unit to store the captured footage.

Security Cameras

Security cameras are the devices through which video is captured and transmitted to the DVR. There are a wide number of cameras varying in specifications and capabilities. Depending on the needs of your security you can accordingly make a purchase. It is advised that you consult with us to provide you with the most optimal setup. This installation in particular guide covers a standard OB-LX700IR50-W.

Power Supply

All the cameras and the DVR would need a 12 volt power supply which provides 4 amps of power for the entire configuration or 500 milliamps for each channel. Power supplies do vary according to the number of cameras that are connected together, this installation is particular to the 8 channel power distribution box.


For the products available with us we provide three types of cables, in this case we will use a Siamese cable that has RG-59 for video transmission along with 18/2 for the power source. The Siamese cable has a tough outer installation.


For this particular installation we would require three types of connectors which are power leads (PT-3 (2 nos )and PT-4(2 nos)) along with two twist BNC connectors required for each of the cameras you would install.

With all this equipment in place, the points where the cameras needs to be mounted needs to be decided. Before getting started on the installation, double check that all the equipment/hardware required for the installation to be set-up is available. Before mounting any of the cameras it would be advised to test the configuration in an easy to access location as it would increase the work if the problem occurs during or after the installation.  To ensure all the equipment is working right, connect the DVR to a power source and attach a wire to each camera one at a time in a manner described below.

Careful thought needs to be put into the locations of the installation eliminating direct access to the cameras. Installation points should be such that the camera needs to be secured. The location of the DVR also needs to be secured. There would be a lapse if an intruder broke in and had access the DVR unit, the whole purpose of recording footage stands to be lost.

The power supply for the surveillance system needs to be mounted within 2 to 5 feet to the location of the DVR unit.  This is ideal as the power wires and cable wires split as they approach the location to the power lines and to the DVR set.  The next step is to run these cables to the points where the cameras are located. It always advised to conceal the wiring in the best manner possible. This process is labour intensive and the right planning is required to achieve the successful results.

At this juncture you should be aware of the location points of the cameras as the next phase would be to mount them. Mount them securely in a manner that the wires for transmission and power are easy attachable.  Siamese cables are cables with two wires, these wires need to manipulated with ease so mount the cameras in a manner that these wires can be sighted easily to join or detach.

To prepare the Siamese wiring, you would have to first begin with the smaller wire which is in the 18/2 size, that acts as the power source to the camera. Stripe back the wires of the 18/2 wire about an inch and a half and attach it to the red and black wire that is also peeled in a similar manner. The same needs to be done for the two wires of the PT-3 connector as well. Once this is done, this needs to be twisted together and connected.  Once completed the connection can now power the camera, similarly,  the same needs to be carried out at the DVR’s end as well.  The next step would be to connect the RG-59 wires to the DVR’s video inputs attaching them firmly to the unit. The inputs on the DVR box are numbered enabling you to display the order of cameras as desired. Once completed switch on the DVR and ensure a monitor is connected to it to view the live feeds.
