Let’s get started.
1. Surveillance cameras and remote video monitoring

Surveillance cameras and remote video monitoring make the outside of your business more secure by using real-time video footage to confirm alarms.
COVERAGE
It depends on the specific cameras and live monitoring system in use.
Usually between 100 and 1800 feet.
BUDGET
It will differ depending on the number and type of security cameras used, as well as the sophistication of the monitoring system.
Usually between 300$ and 6500$ / camera.
RELIABILITY
It varies depending on the quality and durability of the cameras and other system components, as well as the quality of installation and maintenance.
APPLICABLE INDUSTRIES
Most industries including car dealerships, construction, condos, cities, parking lots, truck yards, and others.
PROS
- There are different configuration customization choices depending on the needs of the company.
- Surveillance cameras and remote video monitoring enable continuous security camera monitoring of a location even when no one is present.
- A security operator can confirm the alarm before your pre-set procedure is carried out. For example, the operator can use voice-talk down or call the police to stop the crime before it is too late.
CONS
- The configuration is more complex than for other perimeter security solutions.
- Sometimes alarms go off for no reason or do not go off when they should. So, it is important to set up the cameras correctly and check the performance of the monitoring system regularly.
- Ask your security installer to collaborate with the security operation center to schedule regular walkthroughs.
For the most cost-effective solution for your business, should you use regular or thermal cameras with advanced analytics?
Here are some quick facts about each to help you decide which one to choose.
Regular camera with advanced analytics

How it works
Regular surveillance video cameras with advanced analytics generate an alarm when a specific object or type of object is recognized. We count human bodies as objects.
It usually involves using computer vision and machine learning algorithms to examine the security camera footage in real-time.
To set up such a system, the user must classify the object or type of object they want to be able to detect. It involves labeling many examples of the object in question so that the system can learn to recognize it.
Detecting priorly classified objects based on their shape
Once the system has learned from these examples, it should be able to find the object in future video feeds and trigger an alarm if it does.
Conclusion
Regular cameras can protect your business from crimes by recognizing the presence of certain objects or types of activity in real-time in well-lit areas.
This is our top pick for sites with adequate light sources because it is typically less expensive than thermal cameras.
Thermal cameras with advanced analytics

How it works
Thermal cameras can find people by picking up the heat that they give off. The camera comes with a sensor that is sensitive to infrared light. When the sensor detects infrared radiation in its field of view, it renders an image that shows how warm different things are in the scene.
Detecting humans behind obstacles and in darkness
The human body gives off a lot of heat, and as a result, people tend to stand out in an image produced by a thermal camera.
Even if a person is hiding behind a wall or another obstacle, the camera can still pick up the heat coming from their body.
Because they do not need visible light to see, thermal cameras can also find people when there is not much light or when it is completely dark.
Conclusion
Thermal cameras are effective for protecting your business against crime when lighting is insufficient and the coverage area is expansive.
