Tips for Choosing the CCTV Power Supply

Last updated: November 9, 2022 at 17:16 pm

Regarding security, nothing is more important than seeing what is happening around your property. This is why so many people have turned to CCTV cameras as a way to keep an eye on things. However, ensuring a suitable power supply is one of the most important aspects of having a CCTV system. This article will provide the necessary information for choosing the proper CCTV power supply.

What is a CCTV?

CCTV is an acronym for closed-circuit television. A CCTV system comprises cameras and monitors that record an area’s video footage. Businesses and homeowners often use these systems to deter crime and monitor activity around their property. Big companies often have CCTV systems covering all of their premises indoors and outdoors.

Your family or company might need or want to install a CCTV system for several reasons. If you have a business, CCTV cameras are the physical way to protect your employees and customers. Specifically, it can do the following:

  • Monitor activity: You can use CCTV footage to monitor employee productivity and identify potential safety hazards.
  • Reduce insurance costs: Many insurance companies will offer discounts to businesses with security systems.
  • Prevent crime: CCTV cameras can prevent criminals from targeting your business. Knowing this safety measure will discourage them from even attempting a break-in or robbery.
  • Determine liability: If a crime does occur, companies can use the footage from CCTV cameras to identify the perpetrator and determine liability. This is especially important in the event of an accident.

Power Supply on CCTVs

There are two main types of power supply for CCTV systems. AC Power Supply is the type of power supply that plugs into a wall outlet and provides power to the cameras. AC power supplies are typically used for small CCTV systems. On the other hand, DC Power Supply is a power supply that uses batteries to provide power to the cameras. DC power supplies are typically used for larger CCTV systems. Power vendors also offer dual voltage security cameras, which can be powered by AC and DC power supplies.

Most CCTV cameras will require AC power, as this is the standard type of household electricity. However, some cameras may be designed to work with DC power. It is essential to check your camera’s specifications to see what type of power it requires. If you are not sure, it is always practical to err on the side of caution and go with an AC power supply.

With a suitable power supply, your cameras will be able to function correctly, and it can lead to several problems, such as fuzzy images or even no images. Sometimes, it can cause your camera to overheat and stop working altogether. On the other hand, if your power supply is more than what your camera needs, it can damage your CCTV completely, causing problems with the quality of your images and shortening your camera’s lifespan.

What to look for when choosing CCTV Power Supply

When choosing a CCTV power supply, you must consider some vital things. Check these out before you make your purchase:

The type of system you need.

The initial step is determining the type of CCTV system you’d like to set up. This will determine the kind of power supply you need. An AC power supply will likely suffice if you have a small system. However, you will need a DC power supply if you have a more extensive system.

The voltage that your camera requires.

Most cameras will require between 12 and 24 volts of power. You must ensure that your power supply can provide enough current for your camera. Most cameras will require between 300 and 600 milliamps, and if the voltage wouldn’t match, this could damage your camera directly.

The type of connector that your camera uses.

The most common type of connector is the screw terminal or the BNC connector. However, some cameras may use a barrel connector. Again, it is crucial to check the specifications of your CCTV camera to see what type of connector it requires and what suitable power supply is needed.

The price of the power supply.

Some CCTV power supply vendors promise the world but deliver very little. Do your research to find a reputable vendor that can provide you with a quality power supply at a reasonable price.

How to choose the right power supply for your CCTV cameras?

Now that we’ve listed what to search for when choosing a CCTV power supply, it’s time to establish the right one for your needs. Here are a few tips:

Determine how many cameras you will be using.

This is crucial because you must ensure that the power supply can provide enough power for your cameras.

Research what the company offers.

As mentioned earlier, you want to ensure a quality power supply from a reputable vendor. Therefore, check the reviews from other customers to help you understand what others think about the company and its services. It is also essential to note companies with good customer service so that in case of troubleshooting, you’ll be able to get as much support as you need.

Look for a power supply that comes with a warranty.

This will give you peace of mind knowing that if anything goes wrong with the power supply, you will be able to get it replaced or repaired without having to spend any additional money.

Get an estimate.

Once you have determined what company you want to purchase your power supply from, it is always a good idea to get an estimate from them. It will give you a general idea of how much the power supply will cost and any installation or shipping fees associated with it.

Get a power supply that has backup battery power.

You can still have your cameras up and running during a power outage. A backup is imperative because you don’t want your security system to be down when needed.

Check the price.

You want to pay for your power supply reasonably, but you also want to maintain quality. Find a balance between the two by checking the prices from different vendors and comparing them to what you need.

Power supplies are a crucial part of having a CCTV system. If they wouldn’t work as intended, it could cause a significant setback to your security system. That’s why it is imperative to take a moment to choose the right one for your needs.
