Video Surveillance Troubleshooting

Problems that may arise with security camera systems are sometimes related to powering issues or even factory defects. However, more often than not, these problems are usually attributed to improper cabling and connections, which boils down to the installation.

Prior to security camera system installation, technicians must be mindful of the features, functions, and especially the limitations of the actual hardware. While all installations are different, an understanding of the specific system and the customer’s expectation is crucial for a quality job.

Here are some common installation problems you may come across along with helpful trouble shooting tips.

Rolling Lines On The Screen
Whether they are white or multi-colored, these rolling lines or ghosting over the camera’s video are often caused by video cables that run close to high-voltage power sources.

To prevent this, cameras should be tested at another location prior to installation in order to eliminate any hardware defects as a cause to any future issues. Also, keep wires away from sources that supply high-voltage electrical charges at any point of the run. Improperly grounded electrical circuits can also cause video disturbances, which is why high quality camera cables are crucial.

Infrared Glare/”White Out”
The most common causes of IR glare are reflective surfaces and large, lightly colored areas. “White out” (unrecognizable white silhouettes on screen) is often caused by objects that are too close to the camera. Also, if you install infrared security cameras under eaves, the beams of the IR LEDs may hit parts of the structure and bounce back, causing the reflection to blind the camera.

To combat these potential problems, install your cameras in areas clear of any objects that may cause glare or obstruct the camera’s view. Also, be sure that the user keeps these areas clear (at least three feet). You should also test daytime and low-light conditions before completing installation. Cameras with “Smart IRs” that have dynamic IR strengths can help to alleviate these problems as well and ensure high-quality night time images.

IR Cameras Unable To See In The Dark
In order to employ IR cameras properly, a surface is necessary for the IP light beams to bounce off. For example, when you point a flashlight into the night sky it remains dark because there is nothing allowing the light beams to bounce back.

Choose cameras that have sufficient IR distance capabilities. During installation, point the cameras at an angle facing a surface (ex. ground, wall) and test them under low-light conditions before proceeding.

Extreme Glare During Daylight
If your property has lots of glass doors and windows, you may have an issue with extreme glare. Glare from the sun does not mix well with security cameras, which means a special alternative is necessary.

In these situations, you want to invest in cameras with mechanical Wide Dynamic Range (WDR). These are designed to prevail in extreme lighting conditions. While “digital WDR” does it exist and can be helpful in these situations, it does not work as well as true, mechanical WDR.

Insufficient Power Causing Cameras To Drop Out
Without the proper power source, security cameras will not perform properly, causing them to drop out or lose power. While spec sheets may specify the camera’s power needs, they may not factor in the added power necessary for IR/low-light applications. For example, the system may work fine during the day, but drop out at night when the IR kicks in.

It is advised that you use a power supply which supports twice the voltage requirements of all your cameras combined.

When it comes to power, distance may play a role as well. Voltage drops can occur due to poor quality cables and long distances. To avoid this issue, AC voltage is recommended for runs greater than 250ft.

Inadequate Coverage
With great features and functions come limitations as well. For maximum coverage of your property, first map out your installation to identify areas that need surveillance. Based on the locations, you can determine which specific features you need for certain areas. For example, focal lengths and angles of view should be considered (longer lenses for closer view, shorter lenses for wide-angle shots). In general, license plate cameras should be installed no more than five feet from vehicles and valuable points of interest (such as cash registers, entrances and exits) should have a camera dedicated solely to monitoring that area.
