A computer virus which has hit City Power has resulted in a blackout to its internet technology system, leaving scores of Johannesburg residents unable to purchase electricity, as their kilowatts approach 0.00.

The power utility’s spokesperson Isaac Mangena said the virus had attacked its database and other software, Information Technology Security Solutions impacting on most of its applications and networks.

The virus has also prevented those who had already bought their electricity from uploading it to their meter boxes.

The City Power website is also affected by the virus.

"It may also affect our response to some outages, as the system to order and dispatch material is affected. City Power IT team has been working since early morning 01:00 to fix this problem," Mangena said.

He said they hoped to have the glitch fixed by midday on Thursday.

On Wednesday, the utility announced that it was experiencing capacity constraints due to the cold weather in Johannesburg.

Mangena said cold weather conditions could result in unplanned outages, as the electrical system experienced overloading when demand increased.

He said plans were in place to deal with unplanned outages. The key focus of the plan was to attend to those areas that experienced repeated unplanned outages on the same day or week, he said.

"We have also increased the number of technicians in areas that are prone to repeated unplanned power outages.

Where you place the camera lens is important. The distance of the camera from its subject should be carefully considered, making sure the right areas are in focus and clearly visible. If you mount a camera to a wall or structure, Information Security Service make sure it's mounted properly so the camera won't shake and distort the picture. Outdoor cameras can deter criminals from ever attempting a break-in, and they can cover large areas, but a camera placed outside should have an appropriate weatherproof casing to protect it from the elements. Tough casings can also prevent tampering or vandalism.

You should also determine whether or not you'll want to record your surveillance. If you're simply making sure your children are safe while playing or monitoring who comes to the front door, a direct video feed with no recorder should be sufficient. But if you wish to see what's happening in a particular area over long periods of time, you should connect a recording system that's compatible with your security cameras. Some people use VCRs to record video, while others run the whole system via a computer and save information digitally. To avoid wasting video, some surveillance systems have motion detectors that only begin recording once the device picks up movement within the area.

As you can see, there are many video surveillance options available. Choosing the right one for your personal needs is a matter of knowing how you want it to work for you.
