In the past installing a surveillance system was an expensive both in getting the equipment and getting someone who can watch the system, but that's the past. Now having a security system is very affordable, you can equip your entire home with surveillance cameras for under $1000. The systems that used to be around relied on VHS tapes, so if nobody was their to change the tapes it would simply record over itself which isn't good if you end-up getting robbed and the robbery got taped over. The new modern system use hard drives which can store days of video so you can review the recordings at your leisure.

The other thing that was bad about surveillance systems of the past was the black and white. You would need to know the robber to be able to make a 100% accurate statement to any law enforcement. Now your security footage can get recorded in high definition color. With the improved picture qualities you don't have to worry about blaming the wrong person if anything happens on your property.

If you think that having a surveillance system installed in your house is just for the burglars think again. The uses for this type of technology are endless, for example let's say there is a fire in your house and the insurance company suspects you were at fault and denies your claims well if you had video surveillance of the whole occurrence they have no grounds for denying your claim. With how inexpensive this technology is you really have no excuse not to have it in your home.
