Security Cameras

The number depends on the school’s size, number of entrances, yard and corridors. Main entrances, yard gates, corridors, stairs, the canteen and the perimeter wall are usually considered together. Cameras are not placed in private areas such as toilets, changing rooms and the counseling room. It would not be right to give an exact number without seeing your school; let’s work out your plan together.

Retention depends on the recorder’s disk capacity, the number of cameras, the resolution, and whether recording is continuous or only on motion. First we talk about how far back you want recordings, then choose the disk to match. For personal data protection, it is also right not to keep recordings longer than needed and to limit access.

Yes. When IP cameras and recorders are connected to the internet, you can watch the live view and past recordings on your phone with the manufacturer’s app. During installation we set up the app on your phone with you and show you how to use it. We also recommend setting a strong password for access.

Night vision cameras use infrared light to capture images in the dark too; the viewing distance depends on the camera model. For a clear image, it is important to mount the camera at the right height and angle, with no reflective surface in front of it. Some models can also give a color image in low light.

Cameras made for outdoor use have a specified operating temperature range and a dust and water protection rating (such as IP66 or IP67). Choosing a model that meets these ratings with the summer heat and dust in mind, and placing the camera out of direct sunlight where possible, extends its life. Cleaning the lenses from time to time also keeps the image clear.

Not always. We check the condition of the existing cabling, recorder and cameras; it is often possible to keep the parts that still work and replace only what is needed. We work with brands such as Dahua and Pelco, and we also plan for the system to grow in the future.
