Home Security Camera Motion Sensitive


One of the most effective residential digital video security systems is the home security camera motion sensitive. This camera not only conserves recording time and power resources put can effectively act as an alarm unit, only recording when motion is detected.

There are basically two types of home security systems, digital video security camera systems and security alarms (intrusion alarms). The home security camera motion sensitive combines the advantages of both systems into one by only recording video only when motion is detected. Not only does the owner benefit from digital video documentation of a potential criminal perpetrator inside the home, but if the system is connected to the internet, an email alert can be sent immediately to the owner’s smartphone notifying them of the intrusion.

If the home security camera motion sensitive is used outdoors, (i.e. is an outdoor type digital video security camera) it can also be used to notify the owner of the presence of someone on or approaching the residential property. Cameras of this type are commonly used on extended driveways or gated property/driveways. They can alert the homeowner of a visitor, long before the visitor arrives at a door.

The home security camera motion sensitive is a digital video camera with a built-in Passive InfraRed (PIR) sensor. The PIR scans the camera’s field of view for a differential in heat signatures, such as that caused by a person walking into the PIR and camera’s field of view. When the PIR detects the change in infrared radiation, it interprets this to indicate motion.

The PIR is connected to a relay inside the camera housing. When the PIR senses motion, it triggers the relay to turn the camera on and begin recording. The camera stops recording either when the PIR no longer detects motion or after a pre-programmed time delay. When the camera is battery operated, the PIR conserves battery life (or time between recharge cycles if the batteries or rechargeable) since the electrical drain caused by the PIR function is drastically lower than that needed for the camera to capture video.

There is also another type of home security camera motion sensitive system. The camera for this system is also on and capturing video images. However, the Digital Video Recorder (DVR) and Digital Signal Processor (DSP) are programmed to recognize changes in the video image of the camera’s field of vision. When this occurs, the DVR begins recording as long as the motion is detected. However, this system uses a non-motion sensitive camera and does not offer the advantage of power conservation as does the home security camera motion sensitive.

Residential digital video security systems are incredibly versatile in application these days thanks to improvements in camera, electronics, and computer technology. There are many additional optional features available for home security camera motion sensitive. The following is a list of some of the more common optional features available:
• Day/night vision cameras. These cameras are very sensitive to light such that they can still produce high quality color video in very low light conditions.
• Night vision infrared cameras. These cameras use infrared illumination which is invisible to the human eye to produce high-quality black and white or monochromatic video in total darkness.
• Outdoor cameras. These cameras are designed with a protective enclosure for the purpose of preventing damage to the camera from exposure to weather and other elements (dust for example).
• Wireless cameras. These cameras send their video transmission data using radio waves instead of cables. Using these cameras eliminates the need for an RG-59 coaxial cable to be run from each camera to the DVR. There are also battery operated cameras of this type creating a truly “wireless” camera.
• Internet Protocol (IP) ready cameras. These cameras contain built-in web server technology and can use the internet as a vehicle for networking. Furthermore, these cameras can be monitored anywhere in the world where broadband internet access is available (including 3G and 4G smartphones).
• Hidden or disguised cameras. Camera technology can produce such small digital video cameras that they can be hidden or disguised as another object.

The various features in addition to the motion detector makes the home security camera motion sensitive one of the most effective residential digital video security cameras.
