 Security Camera Buying Guide

You’ve decided to purchase a security camera. You’ve had stock stolen at your store, or someone hit down the mailbox. Regardless of the reason, you’re looking for one thing which is safety here our team is always ready to serve you and your families we are Providing Best CCTV Services in Lahore. Even so, purchasing a security system involves understanding highly technical terms that are difficult to interpret without any prior knowledge of the security camera industry. Terms like RG59U, hd-over-coax, ip cameras, and frames per second (fps) are confusing. Acronyms such as IP, PTZ and HDCVI seem foreign. Suddenly, your safety becomes an overwhelming and time consuming process filled with jargon. Let's break it down. In this guide we will provide you the basic knowledge needed to know which security camera you should buy.

How to choose a security camera?

Professional Surveillance System or Cloud Based Security Camera?

You have been researching which product in the vast and complicated surveillance camera market is going to work for you. If you have tried a Nest cam or other “cloud camera” products, you have realized that video recording with cloud cameras is dependent on your internet speed and the recurring fees add up quickly. Security cameras that record to the cloud sound great but are highly impractical for the budget conscious customer. It doesn’t make sense to buy a camera and then pay monthly fees to record each camera.

A professional camera system allows the home or business owner to pick and choose the best security cameras for his/her use and take advantage of camera resolutions up to Ultra HD 4K. Home consumer products like cloud based cameras fail to offer 4K resolutions with fluid video recording. A professional HD security camera system uses a central recording unit called a Digital Video Recorder (DVR) or Network Video Recorder (NVR) that stores all the footage for cameras wired to it without any monthly recurring costs. Professional systems may sound intimidating at first, but are simpler once you familiarize yourself with the jargon of the security camera industry. The hardest part to putting together your own surveillance system is the physical installation of the cameras and running the wire. If that is too difficult then easily outsource that work to a handyman or local IT company familiar with the process and begin enjoying your newfound security.

To choose the best security cameras for yourself it is important to ask yourself why you need cameras and what you intend to watch with them. The security camera industry jargon is best learned in practice when asking yourself these questions, so let's begin. Because we are providing Best CCTV Services in Pakistan.

How far do you want to see?

During the day, cameras function similarly to the human eye, but a camera’s resolution limits the distance a camera can view. In darkness, cameras view about 5-10 ft less than they can view during the day. For example, if a camera can see a face up to 40ft away during the day, it will see a face clearly about 30-35ft at night. Remember, the picture you see at night will usually not be color, but a black and white video. This is because of the camera’s night vision provided by its infrared LEDs that allow it to see in dark conditions. Infrared LEDs around the camera’s lens illuminate the area the camera is pointed at with light that only the camera can see, and a human cannot. All humans see is a faint glow around the camera as shown to the right.

To understand how far different cameras can see, it is important to understand the following key concepts:

• Resolution
• Lens
• Infrared Night Vision

Resolution: the difference between confusion and conviction

At CCTV Camera World we have developed the below infographic security camera resolution comparison to illustrate the varying degree of clarity provided by different camera resolutions. It is important to note that our security cameras are manufactured with high quality sensors that are true to spec, unlike inexpensive cameras available on your favorite marketplace (named after a tropical rainforest) that use low quality sensors to provide interpolated images. The camera matrix should only be used as a guide for picture quality offered by reputable companies, while cheaper low-end cameras will not match this performance. your Security is our first priority here we are providing Best CCTV Services in Lahore.

Security Camera Resolution Comparison

Security Camera Resolution Comparison As you can see from the camera matrix above, the amount of facial detail you get depends on the resolution of the camera, which is measured in megapixels (MP). Megapixels is a way to quantify the resolution of the camera. The higher the megapixels, the greater the number of pixels captured by the camera. For example, if you compare the video quality of 2MP vs 4MP, you will find the latter captures twice the detail; that's why you can digitally zoom in and see a face up to 40ft away with a 4MP security camera, while the 2MP camera can only provide facial detail up to 20ft, i.e. half that distance of a 4MP. So ask yourself, how far do you want to identify facial detail with each camera? Using the matrix is an easy way to understand the role resolution plays in picture clarity in order to recognize faces at varying distances while the camera maintains a standard viewing angle of around 84 degrees provided by either a 3.6mm or 4mm lens. Be sure to plan your expectations for facial identification before purchasing your security camera system. For example, a 2MP or 3MP camera will suffice in an office environment where you don’t need facial detail more than 20-30ft away from the camera. On the other hand, a warehouse with 20ft ceilings will require a camera that has over 40ft of facial recognition in order to properly identify a perpetrator, or when reporting a work-related injury.
