Active vs Passive Security – How Can Different Security Measures Work Hand-in-Hand?
Active security can be categorised as a system which itself either reacts to an unwanted situation, or gives off a (typically) silent alarm to notify those responsible for reaction that something is amiss. A good example of an active security system would be a motion detector. This system picks up even the slightest of movements, and triggers an alarm to the control room. The monitored control room will then respond accordingly. Perhaps an even simpler way to explain an active security system is that it allows for immediate response, alerts and notifications.
A passive system – such as a non-monitored surveillance device is there mostly for record-keeping purposes. Think of a CCTV camera placed at the entrance to a residential complex. This will record the number-plates and capture a facial image of every person entering the complex. It does not alert security to any breaches, nor does it send silent signals. Rather, it keeps visual record of all parties which can be referred back to in a situation where an incident or breach of security has occurred.
Both security system types have their unique benefits:
Active and Passive Security For During An Intrusion
During an Intrusion – Passive security: records what happens as accurately as possible.
During an Intrusion – Active security: detects what happens as accurately as possible and notifies the proper authorities. Here are some questions active security can help answer during an intrusion:
- When is there a potential intrusion?
Monitored 24-hour control rooms will be alerted to any suspicious activity via CCTV real-time streaming, and may be able to diffuse the situation or at least warn you of the possible threat.
- Is this a legitimate alarm or a false alarm?
Passive systems may be liable to sending off false alarms, which result in a waste of time and resources for the responding company as well as unnecessary call out fees and worries for the customer.
- Which authorities should be notified? (e.g. property manager vs. send law enforcement).
The monitored control room can see whether a van of masked robbers is attempting a home invasion and alert police and dispatch their own backup, or see if it’s a spiteful ex trying to gain access to your property.
- Where is the intruder in the facility?
Criminals will either hide or flee at the first sign of police or security; active security gives the upper hand in being able to locate the criminal via real-time CCTV and notify the responding authority (or their own teams) – which is far more likely ot lead to a successful apprehension and arrest.
- Is the intruder still on site when the police arrive?
The intruder(s) may be armed and simply waiting for police to arrive; active security allows for the criminals whereabouts to be noted and passed onto law enforcement to ensure they are not taken by surprise.
Active and Passive Security For After An Intrusion
After an Intrusion – Active security: helps start review process as soon as possible after the incident.
After an Intrusion – Passive security: allows for review and analysis. Here are some questions passive security can help answer after an intrusion:
- Who broke in?
Surveillance cameras are able to record faces, movements, vehicles and number plates. Passive security may help trace the criminal “after-the-fact”.
- How did the intruder enter the facility?
Again, camera footage may be pulled up for a specific period in which you suspect the crime was committed. You can see where entry was gained and inspect that area for weak spots, tools left behind, perhaps an identifying item such as a cell phone etc., which may help lead law enforcement to a successful arrest.
- When exactly did the intrusion occur?
For insurance purposes it may be beneficial to you to be able to pinpoint exactly where and when an incident occurred; it also aids law enforcement by providing a timeline to help ascertain here they can begin looking for the perpetrator.
- What might have been taken?
You may be overwhelmed to come home to a burgled home, and the last thing on your mind is to look for antique jewellery which may have been stolen. Surveillance footage may be able to help you trace the steps of the burglar to see what they were looking for and what they got away with. It may also help law enforcement uncover their modus operandi to assist in similar future crimes, helping by establishing their pattern.
- How can changes be made in the future to prevent this situation?
Other than finding the weak spots which allowed the perpetrators to gain entry in the first place, you may want to make changes to your existing security setup – i.e. – implementing active security systems.
