CCTV Buyer's Guide To PTZ Cameras

CCTV Help Zone

Perhaps what springs to everyone’s mind when they hear the words CCTV but also somewhat off putting for the rookie CCTV engineer. Here are a few things to look for when picking out the right PTZ camera for your installation.

A B C to go for...


Always choose a style that suits the building so they don’t overpower the setting. Mini PTZ domes with a smaller optical 10x zoom available in white or grey are a great alternative that measure just 14cm in diameter! Order code: SEE-PTZ635W (white) or SEE-PTZ635G (grey).

Buy a keypad controller, even though you can control your PTZ through your DVR or client software, the PTZ705 mini keypad is cheap and a simple method for your customer to use with little training.

Consider our classic range with a dual TVI and analogue output, offered in a choice  of case colours with a variety of brackets and attractive mirrored domes, there’s a style and zoom option (23 or 30x) to suit most sites.

What To Avoid:


Running just a video cable out if you think you’ll need to upgrade to PTZ in the future as they require a data signal to tell the dome which way to turn and how much to zoom in. Don’t panic though if you left it too late, a CCTV mule can send multiple signals including data down just 1 CO-AX. Check out the full range here.

Wiring and then controlling multiple PTZ cameras can seem daunting but use our 3 simple steps to put you on the right track.

  1. Pick a suitable cable, try our PTZ combo cable with cores for power and data as well as an HD quality co-ax for video. (Order code: CAB060)
  2. Decide your cabling route, do you need to run a cable to each from 1 central location (star method) or can you run from one camera to another in a daisy chain fashion.

Did You Know?

Did you know?

Baud rate - named after French Telegraph Engineer Maurice Emile Baudot - is the rate at which data is transferred in a comminucation channel. Eg: 9600 Baud means a transfer speed of 9600 bits per second. The lower the rate, the further the transmission distance without errors. Typically the baud settings of two devices must match in order to comunicate.

Jargon Buster:

Protocol – A specific set of rules or procedures relating to the format and timing of data communication between two devices. A standard procedure that two data devices must accept to be able to understand each other.

PTZ- Pan, Tilt and Zoom cameras have the ability to rotate and angle itself to look at a given area. The zoom function is from the lens of the camera zooming in and out to focus on an object. Great for monitoring a wide area such as a car park.

RS485 - A serial data standard in which data is sent typically down a pair of wires (Twisted Pair/CAT5) to send control commands to devices.
