Burglar alarm systems come in two types in terms of how the sensors are connected in the system: wired and the wireless home security systems.
Wireless home security systems are varied depending on the detection methods used. There are those wireless home security alarms that utilize infrared beams that are activated when there is a “cut” in the beam which is caused by something or someone interrupting the beam between its transmitting point and receiving point; and then there are those that use motion detection methods.
Two most common types of detection methods are the infrared beam field and the use of sound waves. Both would react to changes in field situations and that happens when there is movement inside that certain area being protected. Even a leaf floating in that field can be detected depending on the sensitivity settings. So animals in that area of protection would also be detected, which may give false alarms. There are more sophisticated motion detectors that can be adjusted to lessen if not totally eliminate false alarms caused by non human movements.
The above mentioned home security alarm devices can mostly be left unattended by the user. The best home security systems seem to have a life of their own that even without user attendance or presence it would signal an intrusion and transmit that intrusion appropriately.
One of the best burglar alarm systems around though integrates the use of cameras. These home surveillance camera systems aid greatly in recognizing or identifying the intruder, that can lead to his/her arrest as well as create evidence of the intrusion and other crimes that may be committed. There are wired home security cameras and there are wireless home security cameras.
The wired ones are more convenient in terms of power supply to the camera while wireless ones have their own power sources by the use of batteries, thus, batteries must always be juiced up for normal functioning of the camera. There are motion security cameras though that turns on when motion is detected in its field of coverage and turns off for a certain delay if the motion detected is gone.
This helps in the conservation of the power supplies. For wired home surveillance camera systems, wires are used to also feed the video to a recorder or video monitor or both while wireless home surveillance camera systems transmit through the air with certain transmission bandwidths.
Home surveillance camera systems are not only limited to the inside of the house. Outdoor home security cameras outside the gates or walls are used to outright identify people who might want to enter or are just trying to look for the residents. This is sometimes added with a separate intercom system to establish communication between the outside of the house and inside of the home without coming face to face with one another. This adds in the security of the residents avoiding possible threats of outright physical attacks.
Home surveillance camera systems used outside of the home are weather proofed since they are exposed to the elements of the weather. These include the wrings if wired ones are used.
Ordinary cameras may be used but for a better home surveillance camera system, night vision surveillance cameras may be used in order to have a better contrast or brightness of the field during darkness or with little light than when using ordinary cameras.
Home surveillance camera systems may either be connected to a video monitor or to a recorder or to both. Video recorders may be continuously running or turned on or off automatically by motion security cameras.
Home security systems with integrated home surveillance camera systems could very well be one of the best burglar systems around as there is added intruder identification possible and also existence of evidence of the intrusion and other crimes that could be committed.
