Tips: How to Choose CCTV for Your Home
Surveillance technology that relies on Close Circuit Television (CCTV) is increasingly developing nowadays. CCTV can help you in the event of a crime, demolition or other event that poses a risk to the security of your home.
CCTV is not just a camera and recorder, this tool already offers a high level of security that combines audio, face detection and infrared features, as well as quality night vision recording.
What should you do when you want to buy a CCTV camera for your home?
1. Analog CCTV camera, for longer recording duration
Analog CCTV cameras consist of special cameras and monitors that work only by being connected to a power source (power supply). This is the main advantage of this type of CCTV camera. In addition, some products of this type of camera can be connected to an external hard disk. As a result, you can get a longer video recording duration.
2. How to Choose a Wi-Fi CCTV Camera, for more flexible checking
Most CCTV cameras for homes that are marketed are IP cameras or Wi-Fi cameras (network cameras). This type of camera is connected through the internet network, then you can check it through the application on the cellphone. The advantage of this camera is that the price is much more affordable than analog CCTV cameras.
3. Camera Resolution
CCTV cameras have different types of quality from one another. For example, with HD or TVL quality. This selection is also adjusted to the needs and available budget so that the camera runs effectively.
4. CCTV data storage
Data storage capacity for CCTV is very diverse. You can choose a capacity of 16 GB to 1 TB. Not only that, the storage capacity can be increased by adding an additional hard drive.
5. Choose a camera that can capture objects clearly, even in dark places

Omicron, symptoms and how to deal with it
Based on the results of the study, the most common characteristics that indicate a person is infected with the omicron variant of the Covid-19 infection are as follows:
1. Sore throat but no cough
A sore throat accompanied by a cough is one of the common symptoms when someone is declared infected with the Covid-19 virus.
But in the Omicron variant, the sore throat tends to be itchy, dry, even without coughing.
2. Muscle and joint pain
Reporting from the Gavi.org page, the first reports of Omicron symptoms in South Africa showed a reaction to lower back pain.
In addition, this pain also continues to spread to several other areas such as joints, and muscle pain (myalgia).
Another symptom of Omicron is fatigue so that the body becomes weak and even easily feels tired even though it is not strenuous activity.
These signs of fatigue are constant because they are usually felt by other variants of Covid-19 sufferers.
A painful headache accompanied by a fever like the flu is an inflammatory reaction that the body is fighting a virus.
In Omicron symptoms, this headache feels throbbing, pressured, and sometimes accompanied by a stabbing feeling of mild to severe intensity.
5. Don't lose your sense of smell
In the previous Covid-19 variant, infected patients will experience impaired sense of smell and taste.
But for the Omicron variant, it's the opposite. Patients do not lose their sense of smell and taste so they still feel normal as usual.
After The Accident
What is Water Hammer?
Have you heard about water hammer? Water hammer is the result of a pressure surge, or high-pressure shockwave that propagates through a piping system when a fluid in motion is forced to change direction or stop abruptly. This shockwave is also commonly referred to as a hydraulic shock or hydraulic surge, and may be characterized by a marked banging or knocking sound on the pipes immediately after shutoff.This can happen if you pass through a flood with a water level of more than 50 cm
This term is also called hydrolocking, where water enters through the air filter so that the engine stops suddenly. The second problem can also be caused by water entering the lubrication system so that it mixes with the oil.
