The first step is to raise the strategic and vulnerable points of your home. You need to plan where you want to put the cameras and how many cameras will need. Another point is to define the place a DVR installation, there is no point having a complete security system, high resolution cameras and recording at the time of an event you have your DVR stolen.

Defining the type of camera

To set the type of camera should be considered light the camera's distance from the object and the location has been set. There are cameras that are for internal use only, which have no protection for rain and cameras for outdoor use with IP66 protection system. In addition to the protection index, and the fact that it is internal or external, there is much to be considered as the type of image sensor, the lens type, focal length, among other features.

Defining the type of DVR

After selecting the camera's time to choose the device for image recording. The DVR also known as Stand Alone that is responsible for managing all the cameras make recording and internet connection and monitoring Local and Remote.

Knowing the number of cameras can set the DVR model. Models are 4, 8, 16 and 32 channels. It is recommend to use a model that on at least one camera output, since, after fitted the bill, it can happen to find some vulnerable point.

The Stand alone DVR not included with HD (Hard Disk - HDD) for recording, but allows his internal installation, observe the specifications of your DVR which capacity and model it supports, the Stand Alone models that we work work perfectly with this model (HD Sata Internal DVR to 1 Tera) without the HD your DVR will monitor but will not record the cameras. The vast majority of DVRs available on the market has monitoring via the Internet by PC, Mobile or Tablet, worth checking this information before finalizing the purchase.

Defining the type of cable

Set the camera and DVR, we must choose the type of cabling that will do between the cameras and the DVR Stand Alone. The first step is to calculate the distance from the cameras to the DVR and decide the type of cable that we use, it will be Coaxial cable or UTP Network. Since the cables that reach greater distances are more rigid.

An important note when using a coaxial cable is to see if it is of the bipolar type (which has two wires for power connection) and the amount of fabric that he has, the lower the percentage of larger mesh will be the loss of signal and quality .

Another alternative is a network cable known as UTP, these cables who knows has four metal wire pairs, with the use of an adapter called balun for network cable picture link use two threads, ie with a Network cable can connect 4 cameras. The great advantage of the network cable is to have more flexibility and greater distance when compared to a coaxial cable.

As we already know beyond the image we need electricity for the cameras, when using the network cable can also use 2 wires for image and 2 wires for power.

Setting the font type

This is another important point of your project, Mini spy ameras, Bullet and Dome models use 12V supply with 1 Ampere, you can use a single source for each camera model as the link (Source 12v 1/2 Ampere), or use a shared source of 10 Amperes that allows up to 16 cameras from the same source, Click here to view a shared source

If you choose to place individual sources for each camera, or a shared source, this will depend on your project, it may be that at some points you get an outlet next to the camera, or may have cases that power all cameras need leaving the central point near the DVR, or you may have taken near the cameras but you prefer to send all CPD where you have a UPS for example.
