Are you going to install CCTV cameras? Well, this article would be very helpful for you!

In this article,  we will be covering Top 10 CCTV installation tips and tricks!

However, you can hire an expert to get CCTV singapore services so that they will handle all of your headache.

1. Connection of multiple cameras:

This is one of the most common issues with cctv camera installations. There are basically 4 types of connection; BNC, RCA, Video & Power combo type and one to four wire grounding type. The first three connections (BNC, RCA & Video & Power combo type) are usually used in domestic installations.

If you have multiple cameras with BNC connectors, then run a coaxial cable through the house power lines. Make sure that your power supply is strong enough to support this extra load of the CCTV camera. The next option would be to use an AC  to DC power inverter which is basically used to convert the 220V AC supply to 12V DC. The third option would be using a BNC Video Balun. Connect one end of this balun to the camera and another end of the same to the monitor or DVR unit.

2. Powering up cameras:

Normally , CCTV cameras and DVR units are powered up using the same power supply since they both use DC. But if your installation requires you to use different power supplies, then make sure that you connect a capacitor between the positive and negative leads to avoid voltage spikes which may damage your camera or DVR unit.

3. Powering up multiple cameras:

If you have multiple cameras connected to a single power supply source, make sure that the total load of the cameras does not exceed the maximum current rating of your power supply. If you do not know what it is, kindly ask a professional electrician to help you out!

4. Using DVR’s with UPS (Uninterrupted Power Supply):

To avoid power outages from damaging your DVR, you can use a UPS. This would be the best option if the power supply to your installation location is not stable or poor. In case of a blackout, UPS will kick in and provide you enough time to save all your recordings and shutdown safely without losing any data!

5. Protecting your cables:

To protect your cables in outdoor installations, you can use PVC tubes with slit openings at the bottom. To avoid any water damage to your equipment, provide proper drainage for rainwater. Make sure that there are no puddles of water or snow around your equipment since they might cause short circuits inside the camera and lead to damaged equipment.

6. Properly running the wires:

Cables should always be neatly run in order to avoid any accidents or unnecessary damage such as someone tripping on your cables and falling over them! Make sure that they are not hanging loosely to the floor since this might cause tripping too! Not only that, make sure that the cables are not hanging loosely around any sharp edges or corners. Sharp edges might cut through your cable insulation and eventually lead to complete damage of the wire within few months!

7. Avoiding moisture:

Make sure that there is no water contact with your equipment since wet CCTV cabling may corrode the wires over time and damage your equipment. This is often seen in wet weather conditions or heavy rain!

8. Avoiding dust & debris:

Dust may affect the internal parts of any electronic equipment since it attracts static which eventually damages them over time. So make sure to keep them protected from any dust or debris by keeping them inside a cabinet to avoid any damage.

9. Keeping the equipment safe:

  It is important to keep all your electronic equipment in a dry and indoor location unless you have already set up a well ventilated area for them outdoors. This is to avoid any heat or humidity that may also affect their normal functionality and cause damage to the internal parts due to corrosion or rusting of the metal parts.

10. Waterproofing:

If your CCTV cameras are going to be installed outdoors then you can use a water proof casing over them. This will protect them from any moist weather conditions and prevent any possible damage due to rain, snowfall etc . However , do not forget that a proper drainage system for water should be in place so that your equipment can remain dry at all times!
