• Before hiring a nanny or childcare worker, parents can explain the decision to use a nanny cam to monitor routine childcare tasks. If a prospective nanny objects or considers the nanny cam an intrusion, parents probably won’t want to hire the individual.
• A second benefit to the nanny cam discussion is that, if the prospective employee has any tendency to treat a child improperly, knowledge of nanny cam taping can serve as a deterrent.
• A third benefit supports mutual respect between the childcare worker and employer. A discussion about childcare expectations is essential in any working relationship. The nanny cam’s presence need not cause concern for an ethical, responsible childcare worker.

A security alarm system is a system designed to detect intrusion – unauthorized entry – into a home, business or specific area. Security alarms are used in residential, commercial, industrial, and military properties for protection against robberies, theft, property damage and personal protection against intruders.

Some alarm systems serve one purpose of robbery protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with CCTV systems to automatically record the activities of intruders, and may interface to access control systems. Systems range from small, self-contained noisemakers, to complicated, multi-area systems with computer monitoring and control. This is designed to your needs and specifications. It may even include two-way voice which allows communication between the panel and Monitoring.

• The Alarm Control Panel is known as the “brain” of the system, it reads sensor inputs, tracks and registers arm/disarm status, and signals intrusions and movement. Today, this is typically one or more computer circuit boards inside a metal enclosure, along with a power supply.
• Sensors: Devices this detects intrusions. Sensors may be placed at the perimeter of the protected area, within it, or both. Sensors can detect intruders by many different methods, such as monitoring doors and windows for opening, or by monitoring unoccupied interiors for motions, sound, vibration, or other disturbances.
• Alerting devices: These indicate an alarmed state. Most commonly, these are bells, sirens, and/or flashing lights. Alerting devices serve the dual purposes of warning occupants of intrusion, and potentially scaring off robbers. These devices may also be used to warn occupants of a fire or smoke condition.
• Keypads: Small devices, typically wall-mounted, which function as the human-machine interface to the system. In addition to buttons, keypads typically feature indicator lights, a small multi-character display, or both.
• Interconnections between components. This may consist of direct wiring to the control unit, or wireless links with local power supplies.
• Security devices: Devices to detect unauthorized entry or movements such as spotlights, cameras & lasers.

In addition to the system itself, security alarm systems are often coupled with a monitoring service. In the event of an alarm, the premises control unit contacts a central monitoring station for example ADT or Chubb. Operators at the station see the signal and take appropriate action, such as contacting property owners, notifying police, or dispatching private security forces to the property to assess what the issue is. Such signals may be transmitted via dedicated alarm circuits, telephone lines, or the internet.

Wireless access control allows for:

• Quicker, easier, less disruptive, cheaper maintenance.
• Easier integration with existing access control systems.
• Easy, quick, minimally disruptive installation.
• Battery life in exceeds two years.

It’s worthwhile to start thinking of the benefits of wireless access control as opposed to its wired counterparts. Wireless offers the installer the benefit of a less complicated installation, “especially in those hard to reach areas where trunking just isn’t possible. The end-user in this instance receives a more finished and whole solution which otherwise would have created many more problems such as remodeling and redesigning … if access control was critical for that location.”

He adds that a wireless solution should offer a hybrid variation with wired systems. “The power of hybrid means that wireless becomes complementary as pure wireless does have range limitations.”

Wireless access control solutions allow for quicker installation, but adds that they also provide more options for installation. This reduces the cost of labour and time on-site drastically.

The ease of wireless access is like using Wi-Fi to connect your laptop to the Internet, as opposed to a network cable. It just makes everything easier. The benefits extend to installation where time to install is reduced dramatically, which results in labour cost savings. Secondly, there is a saving on the cost of material, such as cabling, conduit and other peripheral equipment.

Overall maintenance on the system is reduced and less expensive to perform. “Wireless access control solutions form part of the mechanical lock that requires very little maintenance and this is also less susceptible to external interferences like lightning, power spikes and surges that piggyback on cabling. Because it is using the mortise lock in the centre of the door, it also offers better security than using magnetic locks residing at the top of the door.”

“On average, installation takes less time because the wireless lock combines everything found around the door, the lock, the card reader, the request to exit, and the door contact into a single point of installation rather than wiring these components separately.”
