Night Vision Security Camera Tips

Burglars often like to creep in the dark night in hopes of being undetected. This is precisely why night vision security cameras are so important. But keep in mind that the value of night vision cameras is directly connected to their effectiveness and performance. To employ the best night vision surveillance system, keep these things in mind.

  • IP Power

Remember that all IR CCTV cameras have a quoted maximum range. For example, these can range from 5m to 50m or longer. This range is the absolute maximum, meaning at these extremes, your image quality will not be its best. Measuring how far you need to see and then adding a third of that is recommended. For example, if you need to see 30m, it may be advised to invest in a 40m camera.

On the other hand, you don’t want the IR to be too powerful either. Most CCTV cameras cannot adjust the IR brightness, thus, if a subject is too close to a camera designed for long ranges, it will simply look too bright and/or washed out.

  • Wide Angle Lenses

IR LEDS are designed to brightly illuminate the center of an image, therefore, most of these cameras will not have a very wide angle of view. While this is not a common problem, some cameras will have varifocal lenses that can zoom out. With these, be aware that at the wide end of the zoom, the corners of your image will not be covered by night vision.

  • Field Of View

For all security cameras, you want to be sure that the field of view is clear of obstructions, but this is especially important for IR CCTV cameras. If there is something like a branch or leaves in the frame, the LEDs will focus on these and they will be brightly lit. The rest of the image will be made darker in order to compensate, thus rendering the image is useless.

  • Reflection For IR

In order for night vision cameras to work, IR needs something to reflect off of. When users point a camera into an empty field, they may be alarmed when there is nothing but darkness and may assume the night vision is not working, but this is not the case. When a subject moves into range, the IR can reflect off of it, and thus, the subject will be visible.

  • Mounting Height

Keep the height at which your cameras will be installed in mind when you are considering the power of your night vision. This is especially important when installing cameras above ground floor height. For example, if your car is parked 4m away from your house, and your camera is mounted 3m from the ground, the actual distance from camera to car is 5m.
