☛ First, make sure the camera channel or the RF modulator use a channel that has no local TV station.

☛ Then, check the level of power output on the modulator and accordingly, use a coaxial cable to connect the RF output to the input on the booster.

☛ Next, measure the input on the booster and depending on the input, use a mixer to feed the coaxial output of the RF modulator.

☛ Finally, if the booster appears to be a split type and your TV channels receive signals through aerial connection, then using a pass through type of mixer will be recommended.

I haven't ever been questioned on my trustworthiness, but if I did, I would cooperate fully and give everyone anything that they need to complete an investigation. I know that they'll need concrete details, so I'll do my best to give them this kind of information. I wouldn't take it personally because it's our job to maintain integrity and do our due diligence.

This is due to the depth of field changing as the light conditions change and can be easily overcome by following set procedures.

It is all right to discuss an assault that you experienced in your personal life, if you have never encountered one professionally. If you have never experienced an assault, do not make one up, but you can ask whether describing a hypothetical situation would help.

This question is focused on your ability to encounter anger without becoming emotionally triggered yourself and without resorting to violence. A successful outcome in this context involves pacifying the angry person and resolving the situation. If you’ve ever worked in any kind of customer service role, you’ll have something to share. Just remember to focus on the outcome and what it says about your skills and abilities, rather than getting bogged down in telling a funny (or horrifying) story.

The choice is wide and varied dependent on the system requirements. You may require Top mount, Side mount, 230V AC or 24V DC to name just a few.

TOP MOUNT:

☛ Pro: Can fit two IR lamps on the side of the Pan/Tilt. These act as a counter balance enabling you to use a lighter duty Pan/Tilt head.

☛ Pro: Compact size.

☛ Con: Restricted tilt often -45 to 0 dependent on the housing fitted.

☛ Con: Cannot be inverted.

SIDE MOUNT:

☛ Pro: Can be inverted.

☛ Pro: Often cheaper.

☛ Pro: Large tilt often +or- 180

☛ Con: Difficult to mount IR lamps.

☛ Con: Generally large size.

When setting the back focus of a Color camera for low light conditions you should place an ND1 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera for low light conditions you should place an ND3 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera fitted with I/R lighting for low light conditions you should place an IRP (Infra- Red Pass) filter in front of the lens.

☛ Connect the red wire to red and the white wire to the black wire of the camera.

☛ Make sure the red and white wires are positive and negative.

☛ Then, insert the solid or center copper wire of the RG59 to the unit’s yellow video line.

☛ Finally, connect the braided shield of the RG59 to the black ground wire of the camera.

If you don’t have prior experience in security, talk about how you used team-based problem-solving in some other type of position.

Camera housings come in various shapes and sizes. With regard to the correct IP rating protection, this will range from dust and water ingress. This system is governed by a number of European and British standards.

IP55:

☛ Protected against dust - limited ingress.

☛ Protection against low-pressure jets of water from all directions - limited ingress permitted.

IP655:

☛ Protection against low pressure jets of water from all directions - limited ingress Permitted.

This is achieved by following five simple steps:

☛ Set the physical focus of the lens to infinity (clockwise from the front).

☛ Aim the camera at the subject to be viewed.

☛ Release the camera back focus mechanism.

☛ Adjust the back focus to obtain the best possible picture.

☛ Secure the cameras back focus mechanism.

First, check if the device has a BNC connector and the CCTV uses an RCA input. If so, connect the BNC cable to the RCA jack on the monitor; otherwise, plug the RCA camera to the BNC input. Then, push the ‘Source’ button on the remote control to select the input ‘Composite’ on the TV. Finally, make sure there is power to the camera to see the video.

The DVR Board only capture video signal but doesn't compress it, it is the computer CPU and RAM to do this compression work. It's high cost of CPU and RAM resources. In this system the computer CPU and RAM are often overloaded. It is easier to crash than hardware compression system.

This is a commonly asked question and there is no simple answer. Some manufacturers may recommend that their cameras can be run over (X) distance with (Y) cable. This however should still be considered as a general guide. Cable conductor size and installation route must also be taken into consideration. If you are unsure, we would recommend that you contact Technical Support for guidance.

Turn off the ‘Auto Panning’ feature on your device and see if it solves the problem. If not, the unit itself could be at fault that will need to be replaced.

☛ An Auto Iris lens is one that automatically adjusts its iris for changes in the scene lighting levels. The motor that opens and closes the iris is driven by an Amplifier that processes a small electronic signal changing with the light level.

☛ A Direct Drive 'DD' lens does not have this Amplifier and can only operate with a camera fitted with one.

☛ A camera specification will indicate the available output options.

A general rule of thumb is only to use a MI lens in an internal application. This is because you are reliant on the electronic circuitry of the camera compensating for light changes in the scene and this is not able to compensate to the same degree as that of an Auto Iris lens.

This can be achieved in a number of ways, the easiest of which is the installation of a Ground Loop Isolation Transformer. This is best installed at the monitor or recording end of the system.
