CCTV system Through Internet

IP BASED CCTV SYSTEM INSTALLATION

1.    Purchase a DSL modem as required (ADSL or SDSL).

2.    Connect one end of the Ethernet cable to the Ethernet port at the back of the DVR box and the other end to the modem.

3.    Set up your IP address. You can obtain it with your DSL connection.

4.    Activate your Firewall, so as to limit external interference in your recorded data on the Internet.

5.    Connect the router to the DVR with the help of a cable in case you require a network of connections.

6.    You now have an Internet connection through the DVR. Now you are able to view every movement from your  Bussiness Establishment online.

Things We Need:

• IP address
• DSL modem
• An Internet service
• Firewall security
• DVR
• Router
• Ethernet cable

Tips & Warnings

• Acquire a unique static IP address from the subscriber when you go for it. It will save on time and confusion in the Internet connectivity to your device.
• You can also connect to the Internet even if you have a standard dynamic IP.
• Always remember that your IP address is your password to the Internet service; enter it without any mistake.
• Ensure that the LAN cable is appropriately connected

4. Insulation Resistance                      -- Test Procedure: 3
5. Polarity Test                          - Combined with Test: 1
6. Earth Electrode Resistance     --- Test Procedure: 5

After Supply is Connected

7. Isolation Transformer 230/230 Volt for safety Reasons.

Cable Size Calculation

CABLE SIZE CALCULATION

1. ALWAYS REMEMBER {LOAD <CB< CABLE}
2. Calculate the Demand Load or Connected Load Ic = P/1.732 * V * p.f.
3. Choose the Next Size of Circuit Breaker In = ( CB =Ic).
4. Cable Size = (CB x 1.15) /(Ft *Fg)

{ Ft - Temperature Correction Factor ( from A7(g)) If the ambient temperature differ from 30C.
{Fg - Grouping Factor ( From A7(h) If more than one circuit}


Grouping Factor






Temperature Correction Factors

mV/A/m - VALUES

Power Factor Calculation

Voltage Drop Calculation



Example:- If Connect load is 6KW, 2 C PVC non-armoured cable cliped on wall, ambient temperature is 40 C and Power factor is 0.85.
 If Load is Single phase
Load Current Ic = Ic = P/V * p.f.  = 6000/1.732 * 0.85 = 30.6A

Circuit Break Size = 32A ( Next One Higher Value)

Cable Size = CB x 1.15 /Ft * Fg  = 32 * 1.15/0.87*0.85 ( From above Table the value of Ft and Fg )
                 = 49A
From A7(c) Cable Size = 2C x 10mm2 ( One next higher value)

Voltage Drop Calculation

               Ic x L x ( mV/A/m)
 Vd =   ----------------------
                  1000

From Table A7(a) for 70 C Thermoplast PVC non-armoured Cable  "mV/A/m = 18"

So            30.1 x 22 x 18
    Vd = -------------------   = 7.9  so %age Vd = 7.9 /230 = 3.4 % ( which is less than 4% nominal Value)
                    1000

5. contactors of 25Ampere of 220 volt coil supply of Federal Electric and Siemens installed.
6. Siemens Contractor are good for frequest jerks
7. Each Floor control panel made seperatly and installed on each floor level.
