This is why a security camera can be a great addition to a home security system but it can never really take the place of a full fledged home security system. Monthly monitoring services are what make all the difference. Professional monitoring ensures your home is protected at all times. With that being said, some dogs are so friendly and quiet that they'll treat your burglar as another guest. If your dog is overactive, it might make a scene over false alarms. Some experienced burglars will distract a dog with a piece of meat or some other distraction, so it's best to get special training for your dog to teach them how to attack predators. However, special guard dog training can take years and cost thousands of dollars. If you've already got a dog, that's great, but it shouldn't be your primary source of home security. Home security systems can provide safety and coverage that your dog cant and home security companies also offer quality customer service and assistance that makes home security easier to handle. The best home security company is ranked according to our criteria and home security reviews left by customers. Usually, the company with the most positive user reviews is ranked number one at Best Company, but this isn't always the case.
