The Access control system majorly involves round the mode of access to a restricted area, this area is secured and could only be accessible through any form of biometric access. This kind of device is commonly used in Hotel rooms, safes, highly personal zones and offices. This gives only authorised people access to open the door of the restricted environment. Its mostly used as a biometric fingerprint access control and mostly run as a door lock. Sometimes, its been used with the Time and attendance devices making it an access control time management system. This opens the door of the premises to staffs only after clocking in, and also always ensure the reason for going out of the building is stated before leaving.

Crystalhills Software Inc, Registered under the cooperate affairs commission, presently located at Lagos, Nigeria. Started in 2009, As a Software based firm into Web Development, Software Programming, and have since developed and deployed Shopping POS Applications, School management software, a Hospital Management Application and Hotel management portals running in various organisations across the country.

Crystalhills also have a major partnership agreement with one of the world’s most reliable electronics producers to install, develop, upgrade, sell and support all hardware produced from there factory. This as giving us an edge towards been the first electronic manufacturing company by 2018. We deploy devices from our manufacturers and we can upgrade and support it to any length. Also all devices purchased from Crystalhills automatically attract 12month warranty, a maintenance plan replacement policies on damage.

Our Crystal kits contain everything needed to get a new access control system up and running. A wider range of options are available for you from the starter to a professional level. The kind of kit you use for the access control system of your door is dependent on the kind of door you are installing it on and also the standard and level of the network in which you are placing the access control device.

The access control kit includes

- Magnetic Lock
- 12v Power box
- Back Up Battery
- Exit button
- and a biometric Device

Magnetic Lock

A magnetic lock also known as a maglock is a locking device that consists of an electromagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail safe" or "fail secure". A fail-secure locking device remains locked when power is lost. Fail-safe locking devices are unlocked when de-energized. Direct pull electromagnetic locks are inherently fail-safe. Typically the electromagnet portion of the lock is attached to the door frame and a mating armature plate is attached to the door. The two components are in contact when the door is closed. When the electromagnet is energized, a current passing through the electromagnet creates a magnetic flux that causes the armature plate to attract to the electromagnet, creating a locking action. Because the mating area of the electromagnet and armature is relatively large, the force created by the magnetic flux is strong enough to keep the door locked even under stress.




Power Box
This is a 12v supply pack that receive AC current and converts to DC. This power park supplies current into the Maglock, Device and other access control kits. The Access control power box also serves as an housing for the UPS battery and other related devices.

Back Up battery
This is a 12v battery that gives extra power to the access control network. It is always placed in the power park. It’s rechargeable and mostly assures over 24hours extra power on the access control device. The power park serves as the charging circuit for it.


Exit Button
On most Access control systems, the biometric devices is always places at the entrance of the door while a button is places inside the restricted area for people who already gained access and are trying to exit the area. The button places inside the area is called the Exit button, it mostly looks like a switch but could look very stylish at times depending on the equipment been deployed.
