When choosing the right camera for a given purchaser’s needs, there are several things the buyer should look for. The first is a lens that gives the user a clear image of the area covered by the camera from its mounting point. If the area under surveillance is not in focus, then there is no real point to monitoring it. The next feature is the sensor, whenever possible buyers should go for the 1/3 inch CCD sensor as this provides the most information for the DSP to process. The final feature of the camera itself is the output resolution. While many companies may put this feature first, its usefulness is limited by the components in front of it.
The key is to start by identifying the needs a camera has to meet. Once those needs are known, it becomes easier to find the right camera, as opposed to spending a large amount of time trying to select a camera without really knowing how or why it will be used. Knowing what matters to a given purchaser not only speeds the decision process, but also helps to ensure they make the right CCTV camera purchase decision. Therefore, the key is knowledge, knowing what to look for in order to meet the user’s needs.
Once the hardware capabilities have been determined, the next step is to decide which type of camera best fits the user’s needs. Those covering large outdoor areas, such as homeowners wanting to cover their property, may want to consider a day/night camera. Bullet cameras work well for monitoring staff, while ceiling-mounted dome cameras are good for covering the entire premises of a shop or business.
There are a number of things to look for when buying CCTV cameras. Some are technical factors which apply to every situation regardless of the intended use: every camera can benefit from a better lens and high quality sensor. Other factors are more dependent on the intended use of the CCTV camera, as some types are more useful in some situations than others. A day/night camera is great for keeping an eye on visitors coming up the drive, but it may not be the best choice for monitoring staff or business premises.
Many businesses may be better served with either dome cameras covering the entire floor or small bullet cameras to monitor the staff. Regardless of the buyer’s needs, it pays to look for quality. Therefore, understand how CCTV cameras work and the importance of optical zoom as opposed to digital zoom makes it easier to recognize said quality. The most successful purchases are informed purchases, and knowing what to look for makes buying a CCTV camera much easier.
