How to choose the right power supply for your video surveillance camera?


To connect the CCTV cameras, it is necessary to use a power source providing the appropriate voltage and current depending on the project as a whole. In this article, you will learn how to choose the right power supply for your surveillance camera.   

In most modern installations with analog cameras, power is centralized and distributes power to all installed cameras. This type of power supply can be used to connect several cameras according to their maximum current.


Connection is extremely simple as there are labels on each of the connectors, the power supply must be connected to a power outlet using the connectors, and the positive and negative connectors are connected to the cameras. There is also a connector for grounding.

It is recommended to use a power supply with a maximum capacity of 80% to avoid any overload problem. When the system is turned on, there is an initial peak current which can compromise the source if it is too close to maximum capacity. For a video surveillance project, it is necessary to know the current (amperage) consumed by each camera in order to be able to use the appropriate power supply.

This information can be found on the camera label or in the installation manual. In some cases, there is information on the power supply in W (watts). It is therefore sufficient to carry out the conversion by simple division calculation. From there you can calculate which current is used.

Now that we know how much current is needed for one camera, just do the same for the others and add up the total number of cameras that will be used in the project to calculate the power needed, not forgetting to use 80% of the capacity.

Some explanations on image resolution.

No matter what combination of analog or digital surveillance equipment a company has, it is always good to know how it works. The functionality of any CCTV or IP camera focuses on two things: image resolution and field of view (what area is covered on the screen).

The video resolutions currently available.

There are many subdivisions within the categories of video surveillance systems according to the number of pixels, the size of the screen and the panorama (field of vision).

The reason why no table dealing with video resolution comparisons would be complete without an analog section is that there are still a lot of low definition analog systems in use. They are often the only choice for a small business. Cameras using analog technology are often integrated into digital systems as a hybrid surveillance security blanket.

Cameras capable of operating at an angle of 180 or even 360 degrees have also been improved. The video resolution of these applications will also be provided in the table.

The terminology and numeric parameters listed below describe the size (resolution is measured in pixels), how it is transmitted, and how it is stored.

 Best pharmacy safety practices.

Pharmacies are a tempting target for criminals. With the circulation of cash and large quantities of controlled substances, pharmacies are often the target of theft. A quality security camera system can be a valuable tool for loss prevention, management assistance and helping you meet regulatory requirements.

Go to the local requirements page.

The recommendations or requirements for surveillance cameras in pharmacies vary from region to region. In addition to other measures required or recommended by your local licensing agency, high-resolution cameras can provide indirect benefits such as lower insurance costs, or better confidence from your customers.

Show your protection. 

To get the most out of your security camera systems in Chicago, you need to make sure your cameras are visible and that signage signs are posted throughout the pharmacy. Some traders may adopt the theory of "hidden cameras", but security cameras are more effective in preventing theft when potential perpetrators know they are being watched. In addition to the usual entrances and exits, the cameras must monitor all the places where the medicines are stored, dispensed, counted, kept or put back in stock.


Adopt the most modern features.

When thinking about the features that your security camera system needs, it is important to think about how the potential sequences can be used. From images of security cameras that we often see in the news or on YouTube, it seems that many business owners are content with the "just enough" approach.

However, grainy images and poor quality cameras will not help protect your business in the event of theft. Our technicians work with you to map your location to ensure that your cameras have an adequate field of vision and cover all areas for your security needs. With a wide range of cameras with special functions such as panoramic zoom, wide-angle lenses and infrared sensors, we can design a set of cameras that will best meet your security needs.

3 main security controls of a warehouse.

Warehouses face many problems: contraband, theft and even terrorist activities, all pose potential risks, and can threaten the financial and legal well-being of your business. This is why warehouse owners are generally known for their strict and effective security practices.

The importance of warehouse security.

Warehouses are very visited places, daily logistical problems often take a long time to resolve. However, it is essential that warehouse staff and owners take safety and productivity into account. Follow these instructions to stay on top of security risks.




When it comes to warehouse security, the first thing you want to control is who has access to the facility, and when access is granted. In order to monitor this, you need to have an effective video surveillance system, if possible with face recognition. Security, however, should not start at your warehouse door. Obviously, your perimeter must be secured with a fence and a checkpoint. Vehicles should always be watched and parked away from cargo areas. Pickups and deliveries should only take place in designated areas with adequate security measures.

2. Installation of cameras. 

An effective warehouse security plan relies heavily on the security technology in place. Surveillance cameras covering all sides, possible entrances and exits are essential for warehouse security. Monitoring systems must be maintained 24 hours a day, with image storage for at least 30 days. To ensure that you can recognize the people recorded on your cameras, it is important that your system is installed by a team of professionals. Factors such as positioning, programming and the type of security camera are not as easy to determine as you might think. 

 3. Train your employees in safety. 

Security, surveillance and threat awareness are not to be overlooked. In order to guarantee the security of your warehouse, it is necessary that all of your staff understand their security responsibilities. Communicating the importance of security checks to your staff is essential for the processes of receiving, processing, storing and sending filmed images. Employees are much more likely to report threats if they understand why and exactly how to do it, because even small threats can report a potentially compromised shipment or turn into dangerous situations. It goes without saying that regular fire, alarm and natural disaster drills are essential.
