Reasons for DVR not booting
One of the problems of CCTV system users is that the device does not boot suddenly. This means that after turning on the device, the system remains in the initial startup mode and the device’s functionality is unavailable. Such a problem is generally due to damage in software parts or hardware damage.
But what is the cause of such a problem?
Electrical fluctuations are among the most damaging factors for any electronic component. The sensitivity of these fluctuations is much higher in CCTV systems. Due to the presence of constant electrical currents from the cameras, DVR devices are more sensitive to electrical fluctuations. If the electricity in your system fluctuates, you must take the necessary measures to solve this problem.
The problems caused by electrical fluctuations in the DVR include the following:
1⃣ Deletion or damage to the software (firmware) of the device
2⃣ burn of feeding board
3⃣ Burning of the original chip
4⃣ burning of the HDMI port
5. Hard disk damage
The solution to these problems is simple in some cases and impossible in some cases.
If the software of your device is damaged, you can solve the problem by installing new software and updating the device.
Burned power supply board and HDMI controller are also among the things for which hardware repairs can be done.
In cases where the hard disk or the main chip (CPU) of the device is burnt, it may not be possible to solve the problem easily or in some cases it may be impossible.
According to the mentioned contents, it is obvious that efforts to reduce and eliminate electrical fluctuations in the CCTV system are part of the requirements. Here are some ways to prevent these things:
Stabilize device
The stabilizer device is used to adjust and stabilize the voltage. If there is any drop and fluctuation in the electric voltage, this device identifies it and fixes it.
Coaxial image cable electrical protector
RG59 or BNC image cable power protector is a small electrical component that is used to protect closed-circuit equipment during lightning or high voltages.
Use of coaxial image cable surge protector
It is possible to prevent possible damage to other cameras and DVR devices from lightning damage or high voltage to the system by using a small piece called RG59 or BNC image cable power protector.
In the end, our advice to you, dear ones, is to use standard installation equipment such as electrical plastic box, duct, flexi pipe and CCTV protector to protect your equipment. These devices usually have a low price and in addition to protecting your equipment from external factors, they give a more beautiful face to your surveillance system. Also, paying close attention to the time of assembling the power cables and paying attention to the positive and negative ends of the wires, cameras and power sources are among the important points in installing these systems.
